I have been thinking about system presets for rendering based on the 
source and the targets.

In File>Render the default mp4 fileformat (container) or another will be 
used normally.

IMO the render Profile box down arrow may take advantage of a list of 
ready-made preset render profiles that match the fileformat (container) 
w/compression (codec), bit depth (pr samle), pixels (color depth), 
bitrate, quality.

The profile names could have "self-explaining syntax" based on their 
content above.

The default could be a master render profile for a Master render video 
with quality equivalent to the actual imported source file.

Possibly also the equivalent ffmpeg command lines to the profiles could 
be documented to as options and to explain.

The AVC profile names and the first table lines could be a sample for 
furher documentation:
