I selected three video files in MP3Tag and attempted to write the track number "05" to each of the files. After saving the changes to the three files I noticed that only one of the three was updated showing "05" in the track field, the other two show up as "5". I noticed that one file, the one that was updated to track number "05" was an mp4 file, the other two that didn't update as expected were m4v files. I'm I running up against a limitation in the tag structure for m4v files?
I've also had experience with the assign track number feature not padding track numbers 1-9 with a "0" despite having the "leading zeros for track numbers" option being marked as checked. I just remember the file formats selected when using the assign track number feature.
AFAIK the mp4 tag format does not support leading zeros at all. So check what is wrong with the mp4 file.
Yes, this is always the case.
If you really want leading zeros, then, after you have assigned the correct ascending number, use an action of the type "Format value" for TRACK
Format string: $num(%track%,2)
this works only on files with the total number of tracks saved in TRACK.
Thanks for the formatting command for track numbers, I don't think there is anything obviously wrong with the MP4 file in questions, it plays fine which is my main concern. - Rob
