View Full Version : Bitrateviewer max bitrate unit

I've a question about bitrateviewer:

It reports that my peak bitrate is 11602, in kbit, as it states...
How does that make sense?
The nominal bitrate of my stream is 9800000Bit/sec, would be 9570kBit/sec...
But 11602 seems to be plainly wrong...
I noticed that there is no "per second" in the overlay when pointing the mouse on the bitrate field...
But for what unit is the bitrate, then?
I'm somehow too stupid to figure it out!
The background is that my stream has a too high overall bitrate with my audio tracks, but I think it would be possible that the peak bitrate is not as high as the nominal, therefor I want to find out the real peak bitrate, to patch the nominal bitrate to that value.

Thanks in advance!!!

Solved this issue!!
I found a hint here (http://forum.doom9.org/showthread.php?s=&threadid=20709&highlight=bitrateviewer+peak+calculates), that bitrateviewer handles streams with pulldown-flags incorrectly.
I therefor used pulldown to remove all rff-flags, and to set the framerate to 23,976 (was necessary too).
I had to use the commandline-version, the gui-version doesn't support m2v as input...
Now I think I won't have to reencode! Yeah!
By the way, can anybody tell me for certain if in MPEG2 1000 or 1024 is used as factor?
I hate it that one can never be sure how this is handled in different codecs!!

Thanks!!
