I wish I knew the tech level of this video. This is really basic information you could learn within 1 hour of Wikipedia reading. I learned that people in 2012 still thought that macs were better at audio and video. And that pc's are cobbled together unlike macs which are magically formed in mount doom.
as far as I know, .mts files are used by Canon and other cameras to be able to shoot HD footage and store it as quickly and tightly as possible. You're correct, the codec.. or algorithm is doing exactly that, balancing the size with the quality. I think of it like a dehydrated file. When I take a clip into an editor, it will rehydrate (transcode) it and make it more robust and editable.
Great video. Can you please explain why people say that AVI is a container for uncompressed or lossless video but then they say there is a CODEC inside? If it is uncompressed, what is the codec doing? Just zipping and unzipping it? It is just confusing to me.
Oh my goodness! I've been looking long and hard for something like this! Thank you so much for posting this! I was looking forward to what came next when the video ended. Arrrggh! More! I need mooooorrrrreeeee!! :)
Understandable, Not sure I did the best job explaining that. A 'key frame' in compression is a setting that determines how many frames you'll see that are reusing compressed data to draw the scene. If you specify a Key Frame every 24 frames, then every 24th frame will be a fully rendered frame. Sometimes you can see this in overly compressed online video. the picture will be clear and then degrade/pixelate for a second or two before sharpening up again when it reaches another key frame.
This is an excellent lecture about the basics of codecs, but I dying to learn even more! Do you have any other videos along the same subject, anything more in-depth, maybe talking about industry standards and practices?
The most common codec for mp4 would be h.264. But mp4 is tricky as it can be both a container...AND a codec. VLC is a hefty player and I know it has several options for codecs it can play and others you can install as 'packages.' There are tons of simple small programs out there that claim to play anything. But VLC is the most universally used.
thanks Drew as a non video/audio phile thats was enlightening ... now can you suggest a codec for mp4 for any player, i have tried VLC but cannot play mp4 downloads ... thanks again ..
The Bitrate setting will determine how much data (kb) fits within a second. (s) i.e., 10,000 kbps. Regardless of what you specify as the amount of data it can use for each second of video, you can also specify an independent key frame rate. Hope that clears it up! I'm teaching this course again this Semester and I hope to update some of these lectures and add more.
Du-Marc, Yes, avi,mov,mp4 are all containers,, they can have any kind of codec inside. There are some standardized pairings, like mp4s mostly contain h.264. Here's a great video about it. Search Encoding 101 by smedia1
Is there anything I can do to preserve the quality of an AVCHD recorded event after stupidly removing the .mts and not keeping the folder structure? I discovered how much better my end product is if I kept the folder structure but I have files now and no structure.
Eric Feinstein There is software out there that can rebuild the folder structure if you give it a folder full of .mts files. Here's one from Panasonic, eww.pass.panasonic.co.jp/pro-av/support/content/download/EN/restorer.html OR you can use just encoding software, like iSkysoft iMedia converter to transcode the .mts into another format that Power director likes.
Can someone explain to me how its possible for the 1gb compressed file on his sd card to be 60 gb when decoded? And how can all the pixel information still be there?
Gran's Stuff it can be done because as he said that it ill carry the moving information and leave the rest so it has been manipulated like that as compression h 264 AVC advance video codec
Don't waste your time to watch this. It's covers 5% of the entire explanation of Codex. Read the Mpeg-2 or Mpeg-4 or H.263/H.265 Specs. Read the 700 pages book to get a true understanding. No short cuts in Life.
Holy Wow! That is random! This is my 'day-job,' I teach video production at Weber State in Utah. The stuff I was doing at Mashable was my summer fun-job. :) Can't wait to see what you guys create out there! @knite20
It's all in the compression codec. For example, many cameras shoot with the AVCHD codec, it's small in size, but not great for editing. I like to think of it this way, the information is all there but it's "dehydrated" to make writing easier and faster for the camera. Then when your editor like Adobe Premiere or Final Cut get a hold of that condensed footage, it transcodes it to something it can read and display faster, which means much more data. Some Codecs are great for capturing footage, and others are great for editing because they're robust. Often we transcode the file to move from Shooting to Editing... and then often we transcode again for distribution. ;) Does that help?

I already knew all this its not hard to learn tought my self. This guy seems to be a cool teacher i wasnt bored with how he was teaching
Sir
You remind me of Tom Sonia's of surfaced studios
Your teaching is extra ordinary
Thanks
Thank you for this video. Helps me understand what the heck codec is for!
Thanks for the lesson, really broke down what makes up a codec, cheers.
Very nicely explained.Usually unexplained elsewhere.
Still relevant information. Thanks 🙏

Just want to say a big thank your explanation on Codecs.
Thanks Ali,
I'm teaching this course again this Semester, I'll be posting more lectures for sure. Subscribe!
This was pretty good, but needs subtitles on the questions as they are difficult to hear..
Great summary of codec ..thanks for sharing
This guy, really cool, codecs and H.264, and Today H.265 from 1 or 2 K quality to 16k.😁👍
Not yet, but I've done several lectures in my classes. I'll try to get something posted soon.
very interesting class
thanks for sharing Drew Tyler

I love the size of the wobbly whiteboard,. for this hotel conference presentation,.

Excellent pace
I want to know where can I get a free non paid program file to fix up subtitle synchronisation on my movie
Very well explained.
MP4 is not a codec but MPEG-4 is. Popular MPEG-4 standards are known as the advanced simple profile. H.264 is also known as MPEG-4 part 10.
Also in later 1990s and early 2000, when peaple say MPEG-4, it was h.263

can you explain drop frame here, from video i didn't understand the thing 59 29

That was quite informative . Thank you for sharing
Hi sir thanks a lot u r great kindly explain the drop frames in ntsc as a video thanks...
Awesome tutorial!
All these things determine the q.... anyone... anyone... the quuu.... anyone.... anyone... Bueller...
This was really useful. Thanks!
great lesson :p
thanks mark cuban
Well explained for a layman like me. Thank you
Great Video!- Thanks
Thanks for sharing
thanks alot
Is there anything I can do to preserve the quality of an AVCHD recorded event after stupidly removing the .mts and not keeping the folder structure? I discovered how much better my end product is if I kept the folder structure but I have files now and no structure.
I'm using Power director 13.

Thank you Drew! That may be just what I need!
Nice. Well done and thank you.
Thank you so much for this video!
The explanation of drop frames was a little off.
Can someone explain to me how its possible for the 1gb compressed file on his sd card to be 60 gb when decoded? And how can all the pixel information still be there?
Gran's Stuff
it can be done because as he said that it ill carry the moving information and leave the rest so it has been manipulated like that as compression h 264 AVC advance video codec
Its helps a lot! thanks anyway...!
