By far the best explanation I've seen on TH-cam. You've touched on the sample rate issue which is best to prepare for ahead of time; no one else mentioned it.
Wow Curtis, that was 6:33 of pure and concise information. Very informative, easy to understand and to the point. Thanks man!
+mrgreeneye656 Thanks! That's one of my older pieces and I'm a little embarrassed by it now but if the info is still good, may as well keep it posted.
Curtis Judd
You're welcome, it's a noble act of altruism and for that you deserve the praise. Peace..
Thank you! I watched ten videos and this was the only one that solved my problem on Camtasia 9! I appreciate your help.
@erezbens This is a new mic: Giant Squid Audio Mono Omnidirectional Lav. I'll have a review up in the next couple of weeks on it but I can say right now that I like this new mic quite a lot better than the Audio Technica.
Thanks for doing this so succinctly. I couldn't make it through a video from someone else trying to communicate the same thing, but taking twice as long. I gave up and fortunately found your video. Thanks!
blazingdan Thanks, glad it was helpful!
@erezbens It does not have power--the Zoom H1 takes care of that. I was skeptical at first but amazingly, even without power, it sounds better and requires less EQ in post production than the Audio Technica. Part of the reason this works is that the Giant Squid Audio's cable is much shorter and is better shielded. That seems to make a huge difference.
my goodness this just answered my prayers hahha. for the past few months i been recording using a LAV mic into my Voice memo app then sync to video and i always get the audio drift. I could never figure out why... Curtis Thank you so much you really has saved me from lots of headaches. thank you sir.
You're welcome, glad it helped!
Thanks! Stick around, I'll have episodes talking through EQ and compression in the next couple of months.
Thanks for the feedback!
@SparkieWaller2009 Yes, that's my opinion. And of course you can get the H2 a lot closer to your talent which is very important in getting a good final result.
@jackychanelectronics I looked at the specs on the sony voice recorder and the major limitation is that it only records in mp3 format which is a compressed/lossy format. I'd avoid that. The Zoom H1 records in WAV format which is uncompressed so that you have more room to edit it before compressing it in your final video. I'd save up for the Zoom or one of the new Tascam recorders. In any case, you'll probably need to spend at least $90+ to get a decent sounding recorder.
This is absolutely fantastic! Thank you so much, very helpful info presented in a clear and concise way. Well done and thanks for your contribution.
Thanks!
Tip #2 (at 1:02 and 1:34): Make sure your external audio recorder records at the same sampling rate as the camera (usually 48 KHz) to prevent audio drift! That was an eye-opener for me, thanks a lot!
Big mystery solved! :)
Sincerely, I am thankful to the heart. Simple, clear and easy to apply.
Beshoy Nagieb Thanks!
Wow, you have all the tough questions! ;-)
This may be a case where you might try a different editor to see if it is an issue with the Lightworks.
More likely it is the camera. Which camera are you using? Some tend to drift more than others. I have found my Zoom H1 to stay pretty well in sync with both my Nikon D600 and Canon 60D.
I hope this helps a little. Good luck! Sync issues can be quite frustrating...
@stanrose2 I would set the Zoom H4n to 48khz so that you can sync to the scratch audio you capture with the camera. That should avoid the drift issues.
@jackychanelectronics It depends on two main factors: The room that you're shooting in and how close you get the mic to your talent. I would NOT suggest recording into a camera without XLR connectors or a laptop--they both typically have very noisy audio circuitry and you end up with a messy, fuzzy sound. You're better off just getting the Zoom H1 within 12 inches of your talent. If the room has a lot of echo, then the lav definitely helps by getting the mic even closer to your talent.
@sonicblast2404 I'm not sure but most software licenses allow that as long as you only use one at a time. You may need to wade through the license agreement.
Thank you so much for the information on audio drift!
Eric Tyler Thanks! Happy syncing!
Hi! I haven't yet done any chroma-key with other cameras but my sense is that pretty much anything in the $1,000 USD and higher range will do pretty well. That isn't always an option, of course. I think that getting the lighting right is at least as important, possibly more important for good chroma-key work. Soon I'll have a review of a new lighting kit and I'll have to include a part on how it impacts green screen work.
Exactly right! I have another video explaining how to sync it all up--I hope that helps you!
Very informative and clear explanation. Thanks. Now I'm going to go out and buy and audio recorder! Looking at the Sony PCM-A10.
👍
Awesome. Best explanation I've seen so far.
+Mario Monti thanks!
Absolutely--it is best to give yourself a little headroom--not too much, but enough to prevent clipping and distorting and then normalize the sound in post production. That's the way the pros do it. :)
Can someone help? I have audio track extracted by a video. It´s a presentation. I want to dubb the entire presentation by replacing his voce by mine in another language . The point is: I do not want to open a new parallel audio track to record my voice. Instead of that, I want enjoy the same current track by only replacing phrase by phrase by my voice to keep the current sync with his mounth and lips moviments and silence parts. How can I do that?pls
@SparkieWaller2009 That's a pretty good deal. I've actually switched to a different lav just recently that I will be reviewing that I think sounds a lot better and only costs $10 - $15 more. Standby for an update in the next couple of weeks.
Definitely--clap in the frame after you start recording then line the external audio up with the video clap. :)
Is there a way to stop the time increments snapping to each frame? I’m trying to synchronize audio but when I drag wave file left or right it shifts to the next time frame. I think it’s every 10th of a second and I need at least 40th of a second to match wave files (external audio). I've removed the snap option and zoom in as far as I can. Great channel btw.
+CIRCLE OF TONE Your friend for guitar tone hi thanks! Unfortunately this is an issue I've had too and I haven't truly solved it, just put the audio as close as possible. I think it might be a limitation of the software.
Simple and perfect advice. Thanks!
Brilliant. Thank you very much for your time and effort.
You're welcome.
OOps! Please ignore my previous comment. After writing it, I continued my research and came across your comparison of the H1 and the DR05. My question has been answered.
Thanks for the great video. I have the Zoom H2 but no Lavalier Microphone. It is still better to use the Zoom H2 by it self than just the camera mic?
lol make sense..thanks for taking the time to answer some of these crazy questions from a rookie..also i went and bought the the 2700k 300 watt equiv light bulb and it has me looking a lil orange with no umbrella or softbox..if im not mistaken i just set the white balance on my dslr and i should be good right?
Unfortunately, still no feature in Premiere Pro to auto sync. Perhaps in a future version. But again, it's pretty simple. Or, if you do a ton of editing, you may want to invest in the Pluraleyes plugin.
Hi Curtis..this video very helpful to me..tq very much.
+Nazri Salleh Thank you!
Hi Curtics
Thanks for this video
what mic do you use in this video
is it the audio Technica?
THANK YOU! I dont have an audio recorder yet, but this helps me tons!
👍
@curtisjudd Thanks,
I just bought the Giant Squid Audio Mono Omnidirectional Lav,
does it have power?
because on the website it shows only cable
I am going to use it with the Zoom H1
The fastest way to sync multi-cam footage is to use Pluraleyes or Final Cut Studio X. The cheaper but slower way is to just line up all of the footage, one by one as described in the video.
Glad it helped!
thanks man this is a very good video and love ur vids
Thanks!
your videos are very helpful..my zoom h4n arrives tomorrow... you said that we must make sure that the audio sampling rate must be the same on the camera as on the recorder? how do i set the audio sampling rate on my camera... i have a canon Eos 600D ?
Amazing. Super helpful!
Thanks Samoan Scientist!
Thank you very much for your response!
@Tim Bahrij no difference at all! The technique applies to any sort of sound generating visual cue. Hand claps are as good as a slate/clapper board.
Thank you!
love your audio quality, share your workflow on audio. EQs, compression, etc. pls tnx
Thank you for this clarification. I am planning on purchasing the squid omni directional mic with the H1 recorder per your recommendation. I'm wondering about syching as you've talked about in this video with software from imovie in my macbook. Would this work out or do i need to buy additional software. if so, what inexpensive one would you recommend. thanks for your help.
I have two Sony A6300 for a multicam shoot. They have timecode on them. Timecode isn't good enough on it's own to sync audio on two cams but I use a Rodelink wireless system to send clean audio from the boom to my main cam1. And use the timecode to sync cam2 with cam1 which has the good audio from the boom. I then use 'sync using audio' in resolve to get a better match and fine tune manually. It works well and is a great way of syncing three bits of kit.
👍
@jackychanelectronics You're not doing anything wrong--that is expected. Next you need to use an audio editing application to split the stereo track into two mono tracks and just keep the one with your voice. Audicity is free and do that for you. Then you bring your new mono track into your video editor and sync with your video. Best wishes!
Thankyou for this simple neat trick :)
Thank you, great video
+Comiendo Rico thanks!
What would the difference be between your technique and lining up the clap sound peak with contact between the two hands/ boards?
Hi Curtis! Thank you so much for the video! I am able to sync the video and audio perfectly but towards the end the audio and the video are not in the same sync, what do i do? I even tried merging the video and the audio clip as mentioned by you in the other tutorial! Would be great if you could help me on this!
Anup K.R. One of your devices may not be keeping very good time. You might try this: th-cam.com/video/lLQOyaYkhkA/w-d-xo.html
Thank you so much Curtis! Will look into it :)
No need to set the sampling rate on your camera, it is set to 48 kHz automatically. You'll just need to set your H4n to 48 kHz. I hope you like the recorder!
Thank you very much for giving us these editing tips for beginner, I am confused about one of the points, that is why the audio and video should maintain the same sampling rate, what if the audio is higher than the video sampling rate？
Technically it shouldn't matter. The reality is that some devices have clocks which drift quite quickly so even if the start of the clip is in sync, later in the clip, things can be out of sync.
I have zoom H1 , you mean with the sampling rate the 48/16 in the zoom h1?
+Ahmed Gamal I would set the H1 to 48/24.
Thank you for your syncing tutorial. I found it to be both very interesting and very informative. I was actually looking at the Zoom H1 for an external microphone and it seems to meet my requirements. However, the assistant at the camera store suggested an alternative. Are you familiar with the Tascam DR-05 and if you are what is your opinion? Thank you in advance for your comments.
Latest update: I prefer the H1 over the DR-05 if using an external microphone into the recorder. Using the in-built microphones, I prefer the Tascam. I can't remember what I said in my comparison but that's my latest thinking. Best wishes!
Exactly--get that white balance set and let us know how it goes!
Nice tut, HOWEVER, I wish you had shown more about how to use the
SLIDE tool and also the way to link/unlink.
Thank you so much. Perfect 👌
👍
Complete beginner here, so you need the mic, the recorder, a camera and you sync everything up in editing?
Thank you so much for these excellent videos, Curtis! I am very new at this whole thing and I am wondering how you find out the sampling rate on the camera. Thank you!
Hi and thanks! The easiest way is to record a video clip with your camera, import the video clip into a video editing app and then look at the clip's properties. Most apps will show the audio sample rate. Good luck!
O.k., great, thanks! I'll try that.
Very good! Thanks!
Thanks Michael!
i wanted to know what other option i have with my set up..i noticed that since i have pny sdhc class 10 card it stops recording video a lot with the sound but if i disable the sound it's just fine..now i've watghed this video and i see that you said i need the audio from the camera as well..do you have any temporary solution untill i get a better sd card?
In KDEnlive, I can set one audio track as reference and align another track to it with a mouse click. The program does it for me.
I'm surprised that doesn't appear to be a feature on the commercial editors?
Audio drift is also not a problem in KDEnlive. I guess that's a couple of wins for the open source project. :-)
Nice, thanks for sharing.
Many thanks, it was very helpful!
Thanks Dror.
Thank you this was very helpful and informative 👍👍
Thanks Diontae.
Curtis, excellent video. I am new to this so please excuse the elementary question. Are you doing the two recordings at a separate time or simultaneously with the video? Thank you in advance for your help
Hi Bruce, for sync sound, you always record audio at the same time you shoot the video. Best wishes!
In a lot of ways, I think they were better technically than many of us, but then again, there are a lot more of us doing this these days than back then.
If i have a talent lipsync(MUSIC VIDEO) to a prerecorded audio player playing at 44.1 khz(on location), Do I have to record the zoom h4n at 44.1 khz at the same rate? My video audio will be recorded at 48 khz . How do I sync the audio in post ?
Thank you for doing this. What if you have two H1's recording at the same time?
Thanks Kevin, I believe same thing except that you select both audio files along with the video file.
Thanks for this video
Thank you for the help :-) Chris!
Great stuff. Seems so complicated as I am just starting, but very helpful.
+Cookingdude 123 (Sean Maggi) Thanks!
Hi Curtis. Do you have good tips and practices in recording audio separately from your video before syncing them?
Here's a previous episode on recording dialogue and the workflow I generally use: th-cam.com/video/WXKtiwsy7us/w-d-xo.html
I actually composed that using Ableton Live. But there are lots of places online to get free music or music you can use by attributing the artist. I'd start by doing a search for neumannfilms. He's currently composing 30 songs over the next 30 days that you can use for free. There are lots of other places as well--search for royalty free music.
Hi Curtis! My name is William. Thank you for great videos! I have just one questions. I have a lot of files. And first I need to synchronize audio and video. But I can not hold all of them on the time line. How can I save the video file with new audio, that after I can hold them in folder and import them again to the time line. Thank you.
William De Vital I haven't done that before but I would try syncing and then exporting the new merged clips to a lossless format, perhaps using the "Match Source High Bitrate" preset. I'm not sure what that will do to the quality of the video--you will need to test that and tweak the bit rate settings but that would then allow you to delete the source files once you are happy with the quality of the exported, merged clip.
I use Corel Video Studio. Pretty much the same method. Thanks.
Ah, good to know, thanks!
Many thanks for your reply. It's sounds a good idea after doing a paper record to rename them. Had not thought of that ! Love to see a a video of you do one. Cheers Lori.
And just another question. Are you aware of anything on the market which could sync my Nikon record button to my zoom h4n. This would be a great product !
+MyPhotosForever Yes! Tentacle Sync - it isn't cheap but it works nicely! tentaclesync.com
Hi Curtis; Good Video... How do you sync sepatate tracks withOut a video track. With Video, Plural Eyes is superb... But withOut, I'm stuck.
I have several H4N's that I start before an event that isn't suitable for a slapper,,, a church funeral for example... Any suggestions to sync them up,,, withOut a video track?
Also, with Audition, I'm having trouble detaching files (moving independently) once they're loaded into MultiTrack.
TY!
markg
Hi Mark, the first thing I would try (assuming you have Premiere Pro CC?) is to just highlight the audio tracks, right click, and choose merge. If you don't have Premiere Pro CC, I think this is a manual job. In Audition's multitrack view, I'd zoom way in and then nudge the tracks until their waveforms are aligned.
By the way, what is recorded to the separate recorders? Different microphones for different people?
Question: You say to sync the sample rates (48K) between the audio recorder and the video camera to avoid "audio drift". Would I be safe to assume that exact multiples of 48K (such as 96K or 192K) would work equally well? I like to use higher rates for my source recordings. Thanks.
Hi William, yes, multiples work nicely as well.
Hi Curtis, All good stuff but how do you keep track of all the video clips and audio clips?
ie. camera has file name e.g. DC4_1234 and Zoom has audio track STE 003.
I'm ending up with lots of files and I don't know which one belongs to which ?
+MyPhotosForever Great question! This is really a workflow consideration. What I do is for longer pieces where I'm likely to end up with more than 10 or 15 clips of video and audio, I will usually keep a log (on an iPad or just paper). Then when I download all of the clips to my edit computer, I put all of the audio clips in one folder and all of the video clips in another. I then rename each file. I generally name them like this: 01 Intro, 02 Main for my primary footage and sound clips (i.e., the video clip and audio clip for the first clip both get the same name - 01 Intro). Then for B-roll or secondary footage that I will lay atop the primary footage, I'll usually start at 50. For pieces that will be longer with more than 100 clips, I'll number them 001, 002, etc. I'll plan to cover this in an upcoming episode because it is a great question!
Hi Curtis;TY for your quick reply... even with 32mb memory, PP gives me an "out of memory" error message when I attempt to merge/sync the whole 1 hour tracks... (works great with a few seconds though)... Should have mentioned this.... I don't know why the memory is such a problem.... It's never been an issue before with PP or any other program...just this one function.... Am I doing something wrong?
Hmm, I assume you mean 32GB. There are ways to allocate more RAM for Premiere under preferences but I'm not an expert on how that all works. May be best to contact Adobe for help on that. Sorry I couldn't help more.
You are a life saver, did you record 2 separate audios of you clapping and then you recording the actual audio? Or did you do it all on one Audio and just cut them to separate them? I’m very new to this I understood the whole syncing part but did not understand where the audio of the clap came from. Please respond I appreciate it! Great content by the way!
Just one audio clip. I clapped three times.
Hi Curtis, what editing software would you recommend for syncing video and audio? I cannot find anything reasonably priced that works with windows 7.
Premiere Elements if you need to stay at or around $100.
Curtis Judd
Thanks a lot I'll check it out
iMovie will do a great job!
thanks
Hi Curtis, I have a problem with this, trying to sync recorded wav file in Premiere pro cc 2017 with audio from canon 6D, both are 48.000khz 16bit, but I can't get aligned the exact start frames for both, there is a one or two frame difference between these two audio files when I turn on both sources I hear two claps (or one and half) I tried to do this with all zoomed in timeline and snap turned off, anyways can't get to same line the both audios as you show here in 3:47 any tricks? ideas pls?
I got a little bit lucky here that they lined up so perfectly. There are many cases in Premiere where you cannot align them perfectly but should be able to get close enough (within one frame) so that when you mute the camera audio track, it should appear to be in sync. If the difference is more than one frame then there's something else going on.
Thanks for your answer! I will see in final editing if it's ok or not with one frame!
try multicam feature in premier pro cc. select both video and audio than rightclick and click on "creat multicam sequence". it sync well for videos from different cameras shot simultenously. i haven't tried it yet but might work for audio file and video file as well.
sorry for my english :)
Thanks Curtis great tutorial. I use DaVinci Resolve for video editing. My davinci tutor once mentioned using a time code generator for recorder and you should be able to sync video and audio easily. But I still have no idea how to embed time code into an audio recording using a device other than the recorder itself. Hey Curtis what is you opinion about using time code workflow for audio-video sync? Thanks
Here's a general overview of how timecode sync works: th-cam.com/video/o36XYOPp0BE/w-d-xo.html
@@curtisjudd thanks man! Do you think the time code method is better than the traditional methods?
@@gabrieldillaine2079 Not universally, no. If you're working on Multicam projects or you film 10s to 100s of takes in a single filming session, that's when timecode starts to make more sense.
Great Video
Thanks!
Sir ,
Thank you , Great video. I have couple of doubts....
Does the voice recorder with a lavalier gives better sound than a wireless microphone (i.e) Boya wm8 or sennheiser ? I'm about to setup a youtube channel , but on a tight budget . It could really save some bucks which I can use for lighting.
Also how does this help on your day to day editing ... can you manage without any hassle or re-takes ?
Thank you :)
Hi Krishnan, the Zoom H1 and lavalier reduces the risk of RF interference so from that standpoint it reduces retakes. I would avoid wireless unless you have a compelling need for it (e.g. you are live streaming so you cannot sync in post)
Thank you Sir 🙂
Curtis, how would this work with recording a lecture or seminar? The clap probably wouldn't get picked up by both mics from a distance.
A few options that spring to mind: Turn up the gain on your camera mic--you'd be surprised at how likely it is to pick up hand claps. But if not, look for some point in the video where there's a strong correlation between a sound and visual cue of some sort and sync using those points.
Hi, Curtis. Suppose we have the sample rates matched, can audio drift still occur in very long takes, for example, ones that goes on for 3-4 hours?
Yes, absolutely, especially with consumer grade cameras and recorders. Usually drifting occurs well before that. For long-form video, I highly recommend feeding audio from the mixer/recorder to the camera to avoid drift issues.
Thanks for prompt reply! I might have to get a single system setup instead, will dig a little bit deeper. Your videos are very informative.
Useful points about maintaining a scratch reference track on the camera and synching sample rates
And what would you recommend when syncing multiple audio sources against multiple video takes? i.e. Audio post-production for a TV series or film, where different takes are at hand for both audio and video. Thanks. Great video btw!
Two main choices - Pluraleyes from Red Giant is the more expensive option but works well when you have a lot of clips. Other option is to organize your footage and audio files and do them one by one in Premiere. Tedious and time consuming but technically possible.
Curtis Judd Thank you!
Curtis Judd One more question. How do you usually request file delivery for large projects such as films or TV series? I'm about to start working on the audio post for a TV series, the video editors are asking how do I want the project delivered to work on it (xml, aaf, omf, separate audio and video files). Also, does the audio have to be already in sync with the video? Or is that the audio post-producer's job? Thanks again!
***** great question! If they have not begun editing/cutting, I'd usually just require the broadcast wav files. But in this case it sounds like they may already have a cut as they're offering the exchange format files (XML, AAF, OMF). So it depends on what you'll be using to do the audio processing. I haven't done this a lot but here's a blog with some interesting insights on the difference between OMF and AAF: soundslikejoe.com/omf-aaf-tutorial/
I currently record videos on my mobile device, the OnePlus 3. According to online sources, the OnePlus 3 records at bitrate 54mbps.
That said, and forgive me if this is a stupidly worded question, is that the bitrate I would set the Zoom H1 to?
+Edward Lamadrid not a stupid question at all. That bit rate refers to video compression and doesn't impact the audio settings. If in doubt, set the H1 to 24 bit, 48 kHz. Best wishes!
Curtis Judd Thank you for the response! Looking forward to utilizing the Zoom H1 in my future videos.
Thank you so much!! I just sat for 30 minutes for another guy to begin this part of his segment! It was painful..,.i learned nothing. You helped me is much!
Thanks for the feedback!
This is a great video. Thanks for sharing the knowledge.
I have an upcoming Church event "sermon"
where i need to shoot video and capture the audio by connecting my laptop directly to the audio mixer in the media room.
The laptop will take internal audio from the mixer directly (inside the media room)
And
The camera will be mounted on top of the tripod inside the church
So my question is, how can i produce the clap to Sync ?
+Emad Kamel This is a case where you'll probably need to rely on Premiere to sync. When shooting with the camera, make sure it is getting a good audio capture (set your gain so that the audio peaks hit somewhere around -12 to -10dB) and even without the clap, Premiere can usually automatically sync the laptop recording to the video. Best wishes!
+Curtis Judd I work with Adobe Premiere Elements 11
Not too sure if it has the auto sync feature as well or not.
+Emad Kamel I'm not sure since I haven't used Elements but here's a guy that shows how it works in Elements 11 that you might find useful: th-cam.com/video/E2kLOnOnx9c/w-d-xo.html
+Curtis Judd. Much appreciated
Hi I am hoping you can help me. I am filming and recording from my iPhone 6 and recording audio into a Zoom H1 and lapel mic. Do I need to change the sample rate in my phone 6 to match the Zoom H1? I'm not sure how to find these options. Thanks in advance.
Hi Lee, I don't think it is possible to change the sample rate on your phone. iPhone 6 records the audio with video at 44.1 kHz (same for all iPhones, I believe) so what you may want to do is change the sample rate on your Zoom H1 to 44.1 kHz.
Curtis Judd Thanks Curtis appreciate your reply. I'll look at what you said. Great video by the way!
