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 :)
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.
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.
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?
@@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. 😊
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
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.
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 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.
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 RU-vid, 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.
@@DaveKatague every prod will drop this edit with that stuff used in any commercial) so just prepare your storyboard with all timings&framerates and ull never be needed to touch frame blending or optical flow)
