Strange fps value

[Keiyakusha]

Hi. I'm not saying this is x264's fault but have no idea where I should post it so here it is...

I'm using x264 r1542 from x264.nl, mkvmerge 3.3.0 and mediainfo 0.7.31
After encoding to raw stream (here is small sample (http://www.mediafire.com/?hjtmnzmzwuy)) and muxing it to mkv, mediainfo shows: Original frame rate: 2535 078.750 fps.
Isn't it a bit too much? I believe mediainfo shows this field only if FPS was changed on container level, but stream should be 24000/1001 and the same I selected in mkvmerge.

So any thoughts whats going on?

P.S.
I also tried mediainfo 0.7.30, x264 r1510, mkvmerge 3.2.0 (in this order) - result is the same.

your raw stream:
dgavcindexnv: 24000/1001
mediainfo: 23.976

muxing it into mkv with mkvmerge:
dgavcindexnv: 24000/1001
mediainfo: 2535 078.750 fps
(mpc-hc also plays it back at 23.976)

guess you should file a bug report to mediainfo saying it's broken.

Thanks for checking this! I'll ask Zenitram then. :thanks:

Downgrade to MediaInfo 0.7.23BETA. :p

This is definitly a MediaInfo bug.
It will be corrected for next version.

Under the topic "weird framerate"... x264 often (but not always) says "48000/2002" instead of "24000/1001". Why?

For interlaced content, isn't it?
AVC "framerate", for interlaced content, is based on fields (2 fields per frames --> 48 fields per second), I guess that it provides a hint about how is coded the frame (24000/1001 for progressive, 48000/2002 for interlaced)
