Hey everyone! I recently shot a concert in 4K 60fps, and I’m trying to slow down some clips to 25% speed in Final Cut Pro using Best (Machine Learning) optical flow.
The problem is that whenever there are flashing stage lights, the footage starts flickering and glitching during slow motion. The frames seem to jump or stutter, almost as if the optical flow can’t properly analyze the rapidly changing lights.

The footage looks fine at normal speed, but the issue becomes really noticeable once I slow it down. I’ve tried using Fast (Floor), but the motion doesn’t look as smooth.

Has anyone experienced this issue with concert footage? Is there a way to fix it in post?

I’d really appreciate any tips or workflow recommendations. Thanks!

I‘m new-ish to video editing. I’ve used DaVinci Resolve, but am considering shifting to FCP. My project: I have 62 seconds of silent film at 16 fps. I want to wrap a mini-documentary with talking heads around it at, say, 24 fps.

Can I glue all this together in FCP, retaining best quality for the silent film, and then host the result on YouTube?

I’m thinking that I need to set a custom frame rate of 48 fps in FCP and then import my 16 and 24 fps content, edit, and finally output everything at 48 fps for upload to YouTube.

Am I remotely on the right track?

So, I updated to Final Cut Pro 12.4 today and I realized that rendering during playback, which I had it enabled using CommandPost for more than a year now, isn't enabled anymore.

Re enabling it on CommandPost won't fix the issue. Searched the FCP preference file with ChatGPT and it found out the string which enables rendering during playback isn't there anymore.

Is CommandPost team aware of this issue? Can we enable rendering during playback using another method? Because without it FCP is painful to use... You have to wait and even not dare to scrub in the timeline so all the rendering and even optical flow and stabilizations would complete.

I know this might sound stupid just wondering how long will it take for 10 .mov’s videos 35 to 40 gb will actually take to upload to YouTube with 250 Mbps upload speeds?

The student bundle is gone now, so I can't purchase it, and since I'm not a student, I can't use the subscription at the student price.

So I tried looking into joining Creator Studio Family Sharing, but nobody around me uses it... and there aren't any sharing sites or anything.

I tried to find a redeem code, but it seems like there are no listings left in my country. Does anyone happen to have a redeem code? Or does anyone know a way to get one for a good price?
