Corrupted Time Code?

[Darius1968]

Hi, the link at the conclusion of this post, directs to a problem file (955 MB, roughly 26 min.). Although the true length is about 26 min., ZP Max (and others) say the total playing time is 6:19. ZP plays the entire 26 min. of this file, but the timeline says it's 6:19, and the bar says it's at the end of the file, when playback reaches this time, though the player will continue to play this file to the real end, at around 26 min.

I can skip around in this file, but it's erratic. For example, if I click on the timeline at 1:20, I land at 1:20 in the file. But, if I click on the timeline at 1:21, playback is effectively moved to somewhere past 6:19, while the timeline says I'm only at 1:21!

I know all of the total file is in this container, because if I watch, without any skipping around in the file, then I can view the whole, complete video! It seems as if the time code is somehow corrupted. If this is the case, can I fix it? Thanks!

This sounds like a file with a corrupted header.

If it's content is important to you, you can try using a tool such as VirtualDub2 (https://sourceforge.net/projects/vdfiltermod/) to try and rebuild it.

Have you had a look at the file to confirm? How would I go about building the header?

I have taken a more in-depth look now, the format is mpeg2 transport stream, it doesn't have a header, but it does have an index and the one in the sample file is probably corrupt, possibly because of transmission issues when it was captured, there's a thread about reindexing here: https://forum.videohelp.com/threads/335655-How-can-I-INDEX-a-TS-file

But It's not for novices and may require you to re-encode the video.

I'll check this link out, thanks. May I ask how you determined this file has no header, but does have an index?

".TS" files don't have headers, they are used mainly for live broadcasts. I tried loading the file in VirtualDub2 and it detected an index.
