Question - Constant bit rate for Slideshow output No.71581
Rowan  Mail /  )  2020-08-24 00:49:53 ( ID:ny5j87/ow0n )  

I have been trying to generate a slideshow using a constant bitrate. So far I have not been able to get that to work. I have tried to generate mp4 (H.264/AVC), mpeg2 and a few other types and always set the "Rate Control Mode" to "CBR (Constant Bitrate)". When I inspect the output file the bitrate is always variable and is not constant.

Is this a bug or am I missing some other option?
