Topic: Minimum bitrate when transcoding question

Hello,

I have a 4k mp4 video file that is at 30fps with 10Mbps.

When I go to transcode it into 60 fps, the minimum bitrate possible is 40, pushing the quality and bitrate slider all the way to the left. (Using NVENC H.265)

How can get it to the minimum so it at least matches the original file bitrate of 10? Or must it be re-encoded at 4 times the original bitrate for some reason? I went ahead and did the transpose and the output was in fact four times larger than the original ...

Re: Minimum bitrate when transcoding question

minimum value for 4K is 20 Mbps, not 40 hmm

do you really want to encode 4K@60 with single-pass HW encoder at 10 Mbit rate? I personally wouldn't do that...
but you always can switch to the 'advanced' tab and enter any bitrate you like

Sorry I just realized this is a 5k file, that changes everything, please disregard my previous questions
