Support forum for DG Tools

I have enabled "Log Timestamps" in the settings menu, but no timestamp file is produced when saving the project.
Indexing, demuxing and Info Log work though, but no *.timestamps.txt is produced. Am I missing something?
My source is an .mp4 with VFR.
Thanks.

Edit:
Same problem with .mkv. Timestamps creation works however with other containers which I have tested, like .m2ts, .mpg

"Timestamps" refer only to PTS/DTS timestamps in transport or program streams. Adding a dump for MP4 would be a new feature. I have the code already that I use as a standalone executable to identify "VFR in name only". I'll consider integrating it.

I see, thanks. By "VFR in name only" you mean that in fact it is CFR? That's exactly what I wanted to check as my mobile produces progressive video in .mp4 container with an framerate of around 30 fps (and sometimes exactly 29.97), but typically with a low minimum framerate of about 15 fps and a maximum framerate of slightly above 30 fps - at least this is what MediaInfo tells me. I assume that MediaInfo calculates these rates based on few values only and is therefore not very reliable? That is what I wanted to check.
It seems I can demux and remux with CFR (assumefps(29.97)) and the (short) clips are still in sync which would mean that the video is in fact CFR .....

Yes.

My tool dumps the duration of each frame. Sometimes only the first one has an unusual duration and then every following one has the same correct duration. That's what I call VFR in name only.

As I said I will integrate it if possible (there may be licensing issues, I'm checking). If I can't integrate it then I will give you the standalone tool.

Any new thoughts about the integration?

I haven't forgotten about this but it hasn't risen to the top of the priority list yet. I was about to start and then this forced subs issue came up.

Hang in there.

OK, here is the tool for MP4. I cannot integrate it due to licensing issues. I don't have any plans to do anything similar for MKV but if you need it desperately, open another thread and convince me.

Read the Notes.txt file for usage details.

Thank you very much
Very useful to analyze "VFR" mobile phone clips. And no, I don't need the same for .mkv
Thanks again.

You're welcome. Let me know if I can do anything to make it more useful to you.
