Thanks that works fine, but adds up some confusion...
That's the output Igot for the "small" file, I have added the values for the big files as long as they differ. The confusion here is that I have three bitrates, general, video and sound. What is the general bitrate?
General #0
Complete name : /exchange/DVD1/DVD/VIDEO_TS/VTS_01_1.VOB
Format : MPEG-2 Program
Format/Family : MPEG-2
File size : 1024 MiB
PlayTime : 1h 18mn
Bit rate : 1819 Kbps (large file 2365 Kbps)
Video #0
Codec : MPEG-2 Video
Codec profile : Main at Main
Codec settings/Matri : Standard
PlayTime : 1h 18mn
Bit rate : 9800 Kbps (large file 9549 Kbps)
Bit rate mode : CBR
Width : 720 pixels (large file 704 pixels)
Height : 576 pixels
Aspect ratio : 4/3
Frame rate : 25.000 fps
Standard : PAL
Chroma : 4:2:0
Interlacement : Interlaced
Bits/(Pixel*Frame) : 0.945
Audio #0
Codec : AC3
PlayTime : 1h 18mn
Bit rate : 256 Kbps
Bit rate mode : CBR
Channel(s) : 2 channels
Sampling rate : 48 KHz
ChannelPositions : L R
It looks like that the video bitrate (unless it is read out of a header here as well) is really the same. the only significant difference is in the general bit rate, but what does this value stand for?
thanks,
K.
