Turn off optical flow.

When i turn off optical flow, wont that make the video choppy again?

[Meg The Dog · Accepted solution]

Well, from the video you posted it looks to me that optical flow is making a mess of the action of the hand with the brush.

If it were me, I'd easily choose some slight frame stepping over what looks like a gloppy mess of video - but it's up to you.

Test the other two options - Frame Sampling and Frame Blending and see if you get better results.

So you're telling me there is no way that I can make this video any better. Because I tried to use Frame blending and it does not look good at all.

The best way to achieve good slow motion is to shoot the scene at a much higher frame rate than the frame rate of the sequence you are editing on. This will allow you to slow the motion with no artifacts.

Optical Flow Time Remapping - Tips & Tricks for Best Results | Adobe Blog

When you try to use something like Optical flow, the computer has to guess what portion of the scenes belong together and that some times leads to strange results. Not all scenes will work with optical flow.

You can try the Timewarp effect:  Effects > Video Effects > Time > Timewarp and see if you can improve the result.

As Meg said, to get slow motion, you would shoot in a higher frame rate (ex: 59.94) and then slow that down to 40% speed (for example) in a 23.976 fps timeline.

If you shoot something at 23.976 fps and then put it on a 23.976 timeline, and then try to slow it down, there aren't any extra frames to work with so it will be choppy. Optical flow looks at the frames and tries to generate completely new frames in-between. It works best when your footage was filmed with a high shutter speed for very clear frames without blur but even then it can be hit or miss depending on the shot. Most people just film at a higher fps when they want slowmo as this is not interpretive but is based on frames actually captured during filming.

Thank you very much for that info.
