What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
version 22.06.23
Can you repeat the problem? If so, what are the steps?
When I go to split the video track it does some weird stuff. I don’t really know how to explain it but I recorded it.
Thank you! That fixed it! I didn’t even think of trying to convert it. I probably should have tried that first when it wouldn’t let me use the remuxed mp4 file. I do still wonder why it was doing that with the base file tho. Very odd but thanks again for your help
