Funscript out of sync in videos made in Losslesscut?

Also, if it’s from the same video. You might try this:

  1. Cut/Merge like you did (note: you’ll get a few unwanted frames)
  2. Use FunscriptToolbox to create a synchronized script for the recut scene. It uses the audio track for the synchronization, so it should work fine with the unwanted frames.
    "C:\Tools\FunscriptToolbox\FunscriptToolbox.exe" as.cfs -i original-file.funscript -o new-recut-scene.mp4

Note: FunscriptToolbox might not work right now. It seems that the URL that it’s using to download ffmpeg.exe is not responding anymore. I’ll make a new version in a few days.
