I have been using Shotcut for awhile to record gameplay. Never had a problem with it until a couple days ago. Suddenly, I am getting poor syncing once the video has been exported.
- All of my videos have been created with Nvidia GeForce recording, both the ones that work fine and the ones now going out of sync.
- The videos play fine in Shotcut initially, everything is properly synced.
- Have used the same export settings for all videos.
After reading through the forums, much blame is placed on the shoulders of variable frame rates. So, despite having not run into this issue on any of my other variable frame rate videos (prior to this video, I’ve ignored the warning Shotcut gives when adding raw footage to the playlist and the export was fine) I decided to do the conversion Shotcut prompts. After 9 hours, and going from a 40GB source file to over 400GB, I had my constant frame rate file. I played through some of the footage: beginning, some random snippets in the middle, and the last cutscene of dialogue to random check for syncing. All looked well so I snipped the first 9 minutes, watched the full 9 minutes of footage to ensure that it was completely synced (it was) and exported.
And the exported version is still out of sync.
