MKV H.264 media info

[stiltman]

Is there a program like Gspot that will work with MKV H.264?
Specifically, one that will list SAR/PAR/DAR. and one that scans the file, just not the header.

MediaInfo only lists 16:9 or 4:3

try avinaptic, which will give you a bit more information, but it uses slightly different terminology (FAR = frame aspect ratio)

mediainfo will be enough most of the time, since you have the frame dimensions, and the DAR , you can figure out the PAR (in h.264 terminology , SAR is the sample aspect ratio , which is the w:h of the pixels , traditionally it was called PAR or pixel aspect ratio). If the file was encoded with x264, it should print the --sar x:y value in the header information

Thanks

Here's an example:
The original file was
MPEG2
720x480
SAR 1.5
PAR 1.85
DAR 1.778

Encoded file:
Format : Matroska
File size : 1 017 MiB

Overall bit rate : 1 791 Kbps

Additionally... mkvinfo from MKVtoolnix.

Here's and example of why I would like to see more info
Both of these video were in coded from the same source using Handbrake.
The only setting that was changed was Anamorphic strict and auto cropping

Anamorphic stricted with auto crop:
Video
Format : AVC
Format/Info : Advanced Video Codec
Format profile : Main@L3.0
Format settings, CABAC : Yes
Format settings, ReFrames : 4 frames
Muxing mode : Container profile=Unknown@3.0
Codec ID : V_MPEG4/ISO/AVC
Duration : 1h 45mn
Bit rate : 1 494 Kbps
Width : 720 pixels
Height : 468 pixels
Display aspect ratio : 16/9
Frame rate : 23.976 fps
Resolution : 24 bits
Colorimetry : 4:2:0
Scan type : Progressive
Writing library : x264 core 79

Anamorphic strict without any cropping:
Video
Format : AVC
Format/Info : Advanced Video Codec
Format profile : Main@L3.0
Format settings, CABAC : Yes
Format settings, ReFrames : 4 frames
Muxing mode : Container profile=Unknown@3.0
Codec ID : V_MPEG4/ISO/AVC
Duration : 1h 45mn
Bit rate : 1 487 Kbps
Width : 720 pixels
Height : 480 pixels
Display aspect ratio : 16/9
Frame rate : 23.976 fps
Standard : NTSC
Resolution : 24 bits

Both videos show up as the exact same size on the monitor and TV. Both have the right aspect ratio. So something is setting the SAR/PAR/DAR that I can not see.

If I turn off anamorphic strict, the aspect ratio is wrong

I'm not sure what handbrake does, but you can either set the display flag in the container (e.g. mkv) , or encode the --sar x:y value into the video stream. Handbrake uses a modified version, because the information is missing.

For #2, it could be either container flag 16:9 or --sar 32:27 , you won't know unless the data is in the header , or you look at the stream
