SUMMARY
When I transcode a video from VFR to CFR 60fps, during the process the Kdenlive
Interface hangs, I try several times with the same video, until it manages to
process it. Checking, I realize that Kdenlive is the one that hangs (No
response), ffmpeg.exe continues working and finishes normally, converting the
video correctly. I have to cancel Kdenlive so that it can finish running. And
this is how I managed to transcode my videos until now.
STEPS TO REPRODUCE
1. Open a video with VFR
2. Transcode it to CFR 60fps
3. Wait for it to hang, check in Task Management, you will see "No response"
however ffmpeg will continue normally. Note that very rarely the problem does
not occur.
OBSERVED RESULT
The video is processed correctly, ffmpeg finishes normally.. Kdenlive keeps
hanging with "No response", it needs to be cancelled
EXPECTED RESULT
That Kdenlive does not hang and the process ends ok, as it sometimes does with
the same video.
