@"Manual"
I think it could be useful if it is possible to add some overview
table(s) i.e in the manual section FFmpeg Format Options inside
CINELERRA-GG:
That is, valid and Standard Profiles with Compression and Pixels
properties for actual purposes and media, that works for Cin-GG and
Cin-GG multibit respectively?

Andrea, do you want to add this or should I try?

Good idea!
The formats and codecs are too many and with too many variables; an
idea could be to collect the ones used by the users; so we could
indicate the combinations surely functional and tested. What do you
say folks, would you like to send the formats and options you use?
PS (@Phyllis): In the meantime I attach you the modify proposed by Andrew.

Tip:
Pick and compile a list of the most relevant and compatible (standard) file formats/options for Cin-GG/ffmpeg rendering.
While I have just used the generic .mp4 container for my test files, Blu-ray and Ultra HD Blu-ray and DVD video discs use other.

Some reference articles:

IMO users often want encoding settings that fit the input file (source) quality and easy adjustments for the purpose of the output file.
If Cin-GG/ffmpeg automatic could setup default format and render options/parameters/preset this way, it would be a good starting point.
Maybe Cin-gg already is not far away from something like this?

Again, to use my source file as an example:

ffprobe hd01.mov
[...........]
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'hd01.mov':

As this source file is a 10-bit 422 video with pcm audio, I think the following render setup could fit automatic:
Setting Format: rgb(a)-float color model
Render File Format: FFMPEG mp4
Video compression: h264-10bit.mp4 user opti. h265-10bit.mp4
Pixels : yuv422p10le
Bitrate: ?
Quality: ?
Preset: Medium default w/i.e user purpose adjustment faster/slower
Audio: would it be possible and compliant to have the option to just copy the source PCM audio?

(Another one for "home-made HD videos" on Blu-ray discs (BDAV):
Will it be possible to record (copy) source 1080iHDV.m2t files (video and audio) to the BD-R(E) discs?)
