I would support, however, a way to define this in the settings or have a switch here that sets whatever changes I made as the defaults. This way every user can determine what their default state for this window is.
Because productivity and control become an added value
It is correct to insert it in the general settings example
bitrate mode: Constant or Variable
Audio compression 160, 192, 256kb/s
Video frame rate Constant: Yes or No
Video quality: Maximum
Interesting the overall bit rate to have a final product calibrated on 24Mb/s or 56Mb/s and you set it depending on the video cameras you use. If the native file is 48Mb/s set 48.
Is that something you really change a lot? The optimum default for this is codec specific (eg. for 2-channel audio, Opus is transparent at 128kb/s for all but the most extreme audio, and higher bitrates are just wasteful). But the size of the audio content is also generally insignificant compared to the video track, so there’s not much reason to skimp on quality there.
Are there really many people wanting constant bitrate for rendered files these days? It’s really only useful for live streaming over dedicated and strictly constrained bandwidth. For just about every other use it’s sub-optimal.
That seems more like something you’d want custom profiles for, for specific use cases, rather than a button which most people would only hurt themselves with if they click it?
