Windows 10, mp3tag v3.30

I’ve noticed that in some cases mp4 video files get corrupted when editing tags in mp3tag. After editing e.g. year, artist tags and running quick actions to batch rename title tags, the files become corrupted, i.e. when playing them in VLC, there is no more video or audio (duration is still showing, file size is unchanged). I have not been able to figure why it only happens to some files and not others, I’m guessing it could have something to do with the video/audio codecs (since mp4 is a container format)? Is this a known issue?

In the meantime there is a version 3.33 - could you update to the latest version and try again?
