Need Assistance With Strobing Edges On Speed Changes
Hi there, I’m hoping someone can offer up some help on how to fight this issue I’m having. So I’m working with some RED One footage. I have this one shot that is a dolly move from right to left, shot at 48fps, 1/120 shutter, in a 23.976 time base. The clip is fine as shot, but the client would like me to speed it up so the image matches the script a little better. When I attempt to speed this clip up, the edges of the apples start to strobe. Is there anything I can do to smooth this out in AE? Here is a sample.

I think it’s for sure judder after to speaking with a few more experienced people then myself. The footage was shot in a 23.976 time base on a RED One at 48fps, so I overcranked. The footage shows up as 23.976 in REDCine-X Pro.

In the camera, you have an option of what time base you’re project will be. So, I can choose 23.976, 24, 25, 29.97, 30, 59.94, and 60. I think that’s all of them. Then, you need to choose what frame rate you’ll be shooting. Most of the time, we are shooting 24 fps, with a 1/48th shutter. You have the option to activate varispeed. This shot was 48fps, 1/96th shutter, in a 23.976 time base, which means, this shot, to the editor, is a 23.976 clip, with slower motion. I have been doing some experimentation in Twixtor, and I’m getting slightly better results.
