Hello, as a test in Avidemux 2.7.8 I tried re-encoding an mp4 x264 video to both a constant and an average bitrate (same codec), but Mediainfo reports a nominal br for the first one and a constant for the second.
Did the labels\methods get swapped?
P.s: this subforum is called "Main version" but IMO you should remove the "2.6" old version part
They are not really swapped, but you are of course right because the x264 library doesn't have a CBR mode at all, we can only ask it to insert filler when the bitrate gets lower than a particular value. In this sense the "constant bitrate" option is a mild sham. It indeed requests the average bitrate rate control mode from the library (there is no other way to ask for a particular bitrate).
Oh, weird. Thanks for the explanation.
Luckily, however, I mostly use the CRF method since a good while ;)
