Changing start timecode of h.264?

teedoubleyou · 23rd April 2009, 10:27

Hi all,

I've had a look around but can't seem to find an answer.

Is it possible to change the start timecode of an h.264? Basically something along the lines of restream which I can just change it from 01:00:00:00 to 10:00:00:00 for example.

Thanks in advance.

Sorry to do this, I realise it's irritating but after much searching I still haven't found anything that can do this.

I came across TSPE (http://www.videohelp.com/tools/TS_Packet_Editor) which is a great tool, but unfortunately is meant for editing Transport Streams, where as I need something to edit the ES.

Just looking at editing the first GOP timestamp.

Cheers.

What AVC ES timecode are you referring to? GOP headers don't exist in AVC.

That's a good start -- explains a lot.

I'm referring to the start time code of an AVC/H.264, which has a start timecode of 01:00:00:00 but I would like to change to 10:00:00:00.

There is no such time stamp in H.264/AVC streams. Perhaps you are referring to the time code which is specified in your container? In this case you might want to change the start time stamp of the video track in the container if the container supports that. What container are you using anyways? MKV, MP4, MPEG-2 TS?

Note: if this is (as I assume) related to the container you are using, this should be moved into the container discussion forum

Ahhh right, thanks for the information.

It's an MPEG-4, in which case you're right it's a container issue.

Then why does your thread title specifically say H.264?

My bad. I thought he meant MPEG4 ASP video.

Sorry if I'm confusing anyone it's not my intention.

I have an AVC/H.264 which I am using for authoring -- I wanted to change the start timecode as the subtitles were not 10 based, rather they were 01 based. I have since repaired the problem, but for future reference it would have been a lot easier to change the start timecode of the asset. In DVD Authoring you can just use Restream, so I was hoping someone might know of a tool that I could use to do the same but for a BD.

I wasn't aware of them being in a container, which seems where I'm causing some confusion.
