Video duration discrepancy in 'properties'.

[LT2012]

I am a total newby to video editing (expert on PC hardware).

I have some boot-leged videos (VOB files) that have wrong video duration time in 'properties' ( a few seconds instead of ~30 minutes).
When I try to edit the files, it just runs for a few seconds. I converted many to MPEG II format (by using SUPER video converter) just to correct the time duration discrepancy in 'properties'.

Is there a way I can change time duration of video in file 'properties' of VOB files?
Converting the file to another format just to correct duration discrepancy seems to be a big hassle.

Thanks.

newbie at asking questions also? not much info to go on there pardner. maybe try using the free program mediainfo in text mode and copy/paste the results here and ask a more specific question?

p.s. welcome to the forum here.

In Windows, when you right-click on any file, you get a dialogue box that includes an option or link named 'properties'.

If you choose or click on 'properties', a windows opens up showing file properties that inculdes the information on the file.

In 'properties' window, if I click on 'details', I get the duration of file showing as 00:00:42 (42 seconds) while the file is about 1 GB size and the video duration is more than 30 minutes.

When I try to edit the file, it only runs for 42 seconds (the wrong duration of video in video 'properties) instead of more than 30 minutes.

Is there a way I can change/correct the duration of video in file 'properties'?

Ok, so if the total BR for that file is true (how do we truly know?), it should be 9842kbps * 41s = 49.25 MB. Much less than 1GB. So which one is true?

Could be you really ONLY have 41 sec and the rest is GARBAGE padded on, or could be what you were thinking and it's longer but is being mislabelled (or could be somewhere in between length).

You need to run it through an MPEG header/stream repair app, like MPEG2Repair, VideoReDo (or VideoReDoPlus), ReStream, possibly DGIndex could help.

Then see what MediaInfo has to say (do NOT rely on Windows!)...

The file runs fine for 35+ minutes.
It is part of a DVD file that runs fine. The only problem is in editing.
As I mentioned above, when I convert the file to MPEGII format, the new file has correct properties.
The person who burned the DVDs changed the video frame from 720:480 to 480:352 to fit more videos on the same DVD, and during that process, the file properties were screwed up.

Only when I try to edit the videos, the frames only run for the short duration mentioned in properties. I have several of these DVDs with similar problem. I have converted most to MPEGII. I was just wondering if there was an easier solution.

Mpg2Cut2 is pretty good about remuxing VOB and VRO into MPG files that other programs can deal with. Just select File -> Open (VOB), then File -> Save This Clip.

get the original source dvd - 352x480 has already lost more than half it's original quality after being re-encoded. to do it again is just going to make it look that much worse.
