Extract timecodes from MP4 Container

[darktyron]

Hi there. I've got a footage MP4 VFR (with H264 video) and I want to extract the timecodes file and the decimated video, but I don't know how. I've tried muxing it into MKV and then extracting the timecodes with MKVExtractGUI, but it was useless; I'm sure that it's a mix of 23+29+60 fps, but in the timecodes file generated by MKVEXtract it said 46.875001 fps. I've think in use DecombVFR, but, DecombVFR isn't so exact.

What can I do? There's a way to extract the timecodes file and not re-generate?

Thanks and sorry for my english.

google DTSEdit

ffmpegsource("file.mp4",timecodes="timecodes.txt") will write the timecodes, and I'm not sure why you want the decimated video (logically, you'd want either the source video and the timecodes or just the decimated video).

If you still want to decimate, you can use dss2() to decimate to 23.976 fps, and if you want the source, you can use mp4box or something to extract the .264 elementary stream.

Thanks you two. I tried with DTSEdit and it worked perfectly; it generated a timecodes v2 and I converted to v1. The real timecodes were 23fps+11fps+60fps. And, Comatose, I don't understand something: Isn't the source video the same as decimated video? I mean, isn't the source video (extracted from mp4) decimated? And what's dss2() supposed to do? What's its function?

Anyways, I tried with YAMB and extracted the source video, muxed in mp4 container and then loaded with DirectShowSorce to re-encode it.

*Cries*
I am useless at this...
I still dont get how to get the timecode files.
I wish I wasnt so dumb with VFR...

Can anyone give me a link to a gui that extracts timecodes?
Or something that extracts timecodes from MP4. I cant seem to find how to do it...

Sorry for my English...

Ok. I found DTSEdit program, but... Is there any README for it on English? Sorry, no Japanese...

dtsedit -t input.mp4 timecodes.txt

Is dtsedit a free program? (I tried to google a few seconds, but couldn't find anything ...)

dtsedit -t input.mp4 timecodes.txt

Sorry for my English...

Good.
And how to do backwards? Is it possible to add timecodes to CFR file to make a WFR file?
I simply want to find any alternative for tc2mp4

By the way, is tc2mp4 still developing?

[Comatose]

Why do you want an alternative? It works great. Mux video to mp4, add timecodes, add audio.
