Question

Choppy Video When Slowed Down

Hi Community,

I have an unusual problem with my footage shot on a Sony FX3 when slowed down.

The video was shot in 4k at 60fps but when slowed down in a 24fps sequence, what I get is a weird jittery choppy result. This has never happened to me and I have shot videos using same camera a thousand times before without this issue.

What suddenly went wrong? It went from one day to the next and I haven't done anything I hadn't done before. In fact, I compare projects from the previous days to the new ones and I can't see what changed. Someone please help.

 

Cheers!

Kay

    Hey Kay,

     

    Sorry about the issue. Could you let us know what is the clip speed and Time Interpolation set to? Is the playback choppy in the sense that it's skipping frames or does it seem like a preview rendering issue?

     

    Thanks,

    Ishan

      Thank you, Ishan for the response. So mostly I shot in 4k 60fps and 1080p 120fps. I slowed the 4k 60fps footage down to 40% using Frame Sampling. I tried Optical Flow and Frame Bending as well when I was constantly getting a choppy clip. Still the same result. However, when I slow down my 1080 clip by 20%, I get a desired smooth result.

      I have reset my camera to its default factory settings about 3 times aready. I have changed memory cards. Nothing seems to point to the camera, so I thought maybe it's just Adobe.

      Hi Kayero5ED7,

      Sorry. May we have system info? There was a bug with optical flow speed effects on Mac not long ago. I recall that the footage looked rather stuttery after rendering it. Perhaps the bug has returned. Let us know.

       

      Thanks,

      Kevin
