One more thing when you shoot at 24fps with higher shutterspeed say 100 or 120 etc , and then use this method , it will be even smoother and sharper :)
Just what I needed. I didn't know it was so CPU intensive though. As an experiment I've just added 45s stretched to 6:30 and it's going to take 4.5 hours on my M1 max, 64GB MBP!
This is a magic feature for me. My camera frame rate is limited at 4K (budget) so my only option for slomo is to fix it in post. The results are great, even after variable frame rates resulting from ramping.
I did quite a lot of experimentation many years ago with optical flow in After Effects. I found that you could get away with a lot more when slowing down a clip of someone walking in a straight line too or from the camera. But if that motion was faster and lateral/moving across the frame from left to right or vice versa it became choppy and broke pretty fast. This would in some part be due to motion blur. The best way to get slow mo even now in 2024 is to just shoot as many frames as you camera will allow first which means pre plan with the intension of slow mo. Set a high shutter speed maybe double what it should be for the frame rate. You can generally get away with half speed laterally but not much more and even then depends on how erratic and fast moving the action is.
@@jd5787so, the shutter used to be an actual disc that rotated in front of the film. Mow imagine removing half of the disc, or 180 degrees of it. The light will come through half of the rotation, that's the 180 degrees. Now imagine it being a 90 degree shutter. In this case only 90 degrees of the disc are open, meaning a light gets in a quarter of the rotation. Likewise, a 45 degree shutter is even shorter. Hope this helps to visualize and remember how it works. 😊
It seems like Motion Estimation is a Pro Feature. If i use it, i get watermarkt instantly. But also the other settings are helping. But would be cool to know at the beginning, that a free user cant use your tutorial completely.
Render color output is the way to go. Never turn anything on just before you render. Always make sure to inspect every frame of your video before and after rendering.
Just want to note that if youve done a bunch of retiming and want to just set this for everything, going to file > project settings and set the same setting there, thatll handle it for everything when you export
Thank you for making the video. However, I’m somewhat of a newbie. Are you saying that the video of the girl was shot at 24fps? If so, I think I need to revisit these settings again b/c I’ve not been successful at churning out such smooth footage. Maybe it is solely b/c I should render it out first and view that just to prove out the process. I think, up to now, I’ve only been watching it in the timeline at it was likely choking. P.S. I assume that if I see the frame rate playing at 25fps (for my clips) without rendering out then it should appear super smooth, right?
I use this technique a lot to slow down my clips but I actually do use "render in place" to see the result in real time...might not be the best way but it works for me.
If you want to render ist without importing it after the render again you can just duplicate the clip and render it in place with some handles for editing. That should be a little bit faster.

Why so hasty? If you’re using the free version of DR you should already know by now that there are a ton of features unavailable for you, now someone opens you a door for more great opportunities to improve your editing and although you aren’t forced to watch a video on TH-cam, just simply because he didn’t mentioned on the title something you should already know, you just down vote it? Saying thank you will take you a long way towards a brighter future I bet.
I discovered this by accident not too long ago but never thought about adding sharpening to it. Thank you!
I just did it and it came out buttery smooth!!! Thank you !

Hi, how does that translate in degrees? Thanks
@@jd5787 the higher than 180, the better.
This also called overcranking, done a lot in sports

Good stuff Josh. There's so many ways to do everything. We learn little by little, but sure do love DR and my Speed Editor.
Thank you, It worked 🙏
Awesome! Thanks for the invaluable advice

just followed the steps and the result is just buttery smooth
Great! I use in more in FCPX and it works wonderfully as well!
Great to hear!
Very helpful, Josh. Cheers.

great stuff..this really helps.
Nice! Great video. I wonder if closing the shutter angle down to 90 or 45 would help sell it more and get rid of the slight motion blur
definitely would help but it still looks pretty good here
Possibly!
Sorry I am a bit rusty, 180 is shutter speed at 2x fps. What is 90 or 45 then? Faster or slower shutter speed? Thanks

@@rolithesecond thanks mate! I think 360 = same shutter speed as fps. 180 = 2x fps, 90 = 4x fps?
This is basically twixtor for resolve. Very cool :D
I heard Twixtor is still better.
Premiere and FCP also have optical flow
@@hirobriquet twixtor is dogshit, if you try to move or cut clip after you applied twixtor, it will mess up the timeline completely
Hello, you can export videos with chapter marks, because that option is there but it does not export with chapter marks.

Seems like you need some tips on how to make run heavy projects play smooth
Sorry but I am bit confused about "O" and "i" ... what is the purpose of those and is it necessary to do that?
Thank you!
Awesome!
Does it work in free version not the studio version ?
Optical flow is available in the free version, but speed warp is not.
Nice, thanks!
Great, how do u work on timeline after applying changes (speed warp). There is lag.
old comment, but he mentions this in the video -- disable retime and scaling until you render the video
i have a question, why do you use the resize filter ? (and why sharper?)
Good job. Good info. Thanks. Sub'd
The GPU failed to perform image processing because of an error Error code 702 showing while using Speed wrap🥴any solution please?
it's good. i like it
I use this technique a lot to slow down my clips but I actually do use "render in place" to see the result in real time...might not be the best way but it works for me.
This is what I do... Why wouldnt it be the best way?
Sweet!
and what If I do a speed ramp/slowmo in one single track with key frames? does it work then the same way?
render the clip out in slowmotion and then ad speed ramp to speed up parts
Nice video! Is this available on free version??
Nope, you will get fullscreen watermark
Nem sempre fica bom.
Nice & Thanks :)
It was recordeed in whar frame rate ? :)
24
why are you putting a "p" after the framerate?
Thanks

What Mac are you using?
MacBook Pro M1
@@JoshChappell so I guess I’ll have same issues with my M1 Mac Studio?
I would just render in place
Lets be honest, only Topaz Video AI can make 25fps in 120fps to look realistic and perfect 👍🏼
It might take a week to render
gooood iam from brasil
What's your Graphic Card Specs ?
Wow
That was 96p, not 120p... 😉
Wow this is amazing. Too bad the render is so slow.
why do you even need this if tou have a cam like fx3, used on preview?) just use 100\120p internal recording with x4\x5 S&Q and get clean result)
cause some film purists shoot on low frame rates, then the editor actually needs more for the edit haha

@@Alive1exe_channelagreed, but not everyone is working with the same competency lol😂
@@Alive1exe_channelknowing how to problem solve as much as possible is a stronger mindset as an editor than dismissing the incredible tech this can do

this are 96fps not 120
it needs to be reduced to 20% actually
I just did but my grafic card exploded. Im not kidding, be carefull
This will burn your computer to the ground though 😁
Only in studio available, clickbait

hm but when i look at her face ... see some shakes
You HAVE TO put the word studio in such videos. Otherwise, this is a click bait. And you get a thumb down from me.
