I do a lot of encoding of .mkv to .mp4 (mostly to hardcode subtitles for compatibility for mobile devices), and I've run into a recurring problem. I like to tag my .mp4's using Mp3tag for organizational purposes, but I've found that my files are often, but not always, corrupted after I've tagged them. I'll just be watching the video and then there'll be a "hole" in the video. I can confirm that the files were just fine prior to tagging.
This doesn't apply to all .mp4's; I've downloaded hundreds of .mp4's from YouTube, tagged them the exact same way, and have never had a single problem with them. And it's not exclusive to my personal encodes, either; some .mp4's that I've downloaded from other sources seem to be more susceptible to being glitched.
This was a major pain until just recently (because I had no way of telling if a file was glitched or not unless I watched it), when I discovered that if I ran the audio of that tagged file back through my encoder and jump to the end, the audio will be glitched if there's a hole in the file. So, I've had to resort to copying any files after encoding, tagging the copy, running the audio check, and then re-copying, re-tagging and re-checking until I get a tagged file that isn't glitched.
What I'm looking for is a way to:
Repair files that have been glitched because of tagging, and/or
Encode/tag files without them getting corrupted.
I use Xvid4PSP 5.10.346 to encode and the latest versions of Mp3tag to tag. I can provide an example of an untagged file that runs fine and a copy of that file after tagging that was glitched.
And for what it's worth, it seems as though doing things one at a time makes the likelihood of the files glitching go down - specifically copying and tagging.
