HB 1.3.3 (2020061300)
When using "Constant Quality"; is it possible to set in the "advanced options" a max of bitrate to use?
In other words, set a bitrate limit.

Re: Set a Bitrate limit when using CQ
Sure, with vbv-maxrate and vbv-bufsize.
Re: Set a Bitrate limit when using CQ
Thanks,
After several trial-runs, I found that encoding 720p@RF20 and RF19 provided the best balance of quality, file size, and encode times. The problem was that encoding 1080p remuxed files while maintaining a 1:1 resolution would result in files been too large, however, I will test the vbv-maxrate and vbv-bufsize parameters for only 1080p output.
I found the parameter arguments notes to use here:

Re: Set a Bitrate limit when using CQ
With an RF that low, you're better off with keeping the 1080p frame size and going to an RF in the low 20s.
Although encode time will be slower unless you pick a faster preset; about one faster on the list should do it.

I did, I went back to maintaining the frame@1080 after those six files@720 completed.
For some reason those six files re-encoded with a higher bitrate than the source (13.5mb/s) when everything else I have re-coded using the same profile/settings ended up well below the source bitrate/size which is why these particular six files would have definitely required a limit/constraint using the vbv-maxrate while using the same 1080-profile.
