[Bug] MKV Conversion

[paulbuchan]

I used SE to download a video from YouTube. It generated a mkv that plays fine in VLC. I went to convert this to an prores file (or anything), it completes instantly, with a file of a few kbs. Meanwhile, if I try the same thing but converting to H264 mp4, in my activity monitor, I have a runaway ffmpeg process that is using up all my system resources, I have to quit that process to release the system resources.

I'm on a M1 Mac, running Sonoma 14.1.1, Running SE 17.7

Below is the console from SE for the ProRes:

I can send the file upon request outside of GH if needed.

Disable GPU encoding should solve your issue for this file.

Paul.

Thanks Paul, I just tried changing the settings in the status bar (I assume that's the settings that you're referencing) but I'm still getting the same result.

[paulpacifico]

Can you send me your file for checking on my side?

Thanks, Paul.
