I see that this thread is dead, but I'll add my update here in any case:
I used to use gspot to catalog my collection into an Excel file, with loads of tag data, but gspot doesn't work with MKV, so I'm trying to get MC to do the same (without success yet)
To start with, I have around 8000 video files, ranging in NTSC, PAL, and 1080p sizes. 75% of the collection is in AVI and 25% in MKV. I run CCCP, and use WXP.
Recently I found that when I have a fresh MC running, and I select several files and then "Update Library (from tags)" then many of the files will populate the Width, Height, Duration and Bitrate fields (maybe other tags update, but I only track these). I usually know when the file is populating when the "Please Wait..." window has a slow running ticker (1 of 25, 2 of 25, etc.). But once the ticker starts to go fast then I know that nothing is happening. Anyway, what I found is that when the files no longer update the fields, then I exit out of MC and then load it back up, and run "Update Library (from tags)" again. And it then works for a short while (maybe 30 to 300 files or so). I always have to select a small number of files, in order for it to work. And I find that when it stops working for one file, then it won't work for any subsequent file until I exit and load MC again. So I did this around 30 times (exit and reloading MC), to try to get the entire collection updated. And I successfully tagged around 7000 files. But I now find that there are around 800 videos which refuse to update the fields (so 10% of the collection is left, which is better than when I started out). What is even more suspect is that from these 800 files, some of the fields will update, but then when I exit and go back into MC, then the updates are lost (even after repeated tries).
So I'm trying to read through the forums what could be the issue, and I can't figure out why some file tags update and others do not. From these files which refuse to update the tags:
- some are MKV (with H.264 video ranging from PAL, NTSC or HD)
- some are AVI (with XVID videos in PAL or NTSC sizes)
- File sizes are anywhere from 40MB to 10GB in size
So I can't find the common denominator in these files which prevents the tags from being saved.
