Why doesn't handbrake re-encode show video bitrate in MediaInfo?

[KushSmoka420]

I had an .MKV video that was 7.49GB with video bit rate of 8396 kbps (according to MediaInfo). I wanted to shrink it down to so it would fit on a a single layer DVD-R. I ended up using handbrake to do the re-encode. For video "quality" setting I chose AVG bitrate and used 4000 kbps, also used 2-pass encoding with turbo first pass. The resulting file is 3.46GB, but when viewing in MediaInfo, it does not give any info on the video bitrate. Why?

because mediaInfo not always reports the average bitrate.
only if a. it is directly specified in the start header or b. it can be easily calculated through size/length (this is only done for some formats iirc. and mediaInfo does not really care about container overheads)

If you are curious, then you can watch the varying bitrate in VLC->tools->media information ->statistics

MPEG File Bitrate Viewer (it works for many different file types, not just MPG).



As to why you can't see the bitrate after Handbrake -- is the reencode variable frame rate?
