I’ve already edited and finished a project and while the audio and video sync perfectly in the editor (this happens across all the tracks, by the way), it goes out of sync after I export it. I’m even running the latest version of Shotcut, as of July 1st, 2018. I’m also using Windows 10. I’ve used both .mov and .mp4 video clips, and I’ve used both .wav and .mp3 audio files.
I export my video using the ‘H.264 High Profile’ option, and the only things I changed are the quality to 100% and the frame rate, which varies. I’ve read about exporting the video with the same frame rate as the clips used in the editor, but the clips can vary from 29.97 fps to 30 fps. In one of the clips, it even dips down to 25 fps. I don’t know if this adds to anything, but I’ve also noted that only .mov clips are 30 fps and that any clip below 30 fps is of an .mp4 format.
Additionally, I’ve heard about ffmpeg, but it doesn’t apply to my situation, or at least I don’t know how to apply that solution to my situation. I’ve tried using it upon both the exported video (.mp4) and even the project itself (.mlt), but error messages appeared both times even though I typed the commands correctly. I’ve noticed that instead of “Open command window here”, it says “Open Powershell window here”. I don’t know if this changes anything, but I thought that maybe it’d be helpful to put out there.
Any help on this would be much appreciated, thank you!
PS: I’m not very well-versed with much editing vocabulary, so please be patient with me if I do not understand something.
