It would also be useful with an updated list over supported formats,
codecs and bit-rates, based on CinGG's internal ffmpeg engine.
Some codecs like Cineform is not mentioned in the current manual.
CineformHD is only mentioned in the "Overview on Formats and Codecs"
appendix.
Ok, there it was mentioned. I searched only the html manual index and
didn't find it.
If you provide a brief description we can incorporate it
into this section. Or you can do a more in-depth specific section in
the "Rendering" chapter, "Some specific Rendering" section. I don't
know if the manual is the right place to describe the various codecs,
though. In the "Private Options" section, it is recommended to study
the white papers of each codecs we want to use:
"Render presets in CINELERRA-GG should work Out Of the Box. You can
still configure the Global Options and Private Options manually.
Finding the combination of parameters that best suits your needs, or
simply finding working (legal) combinations, requires studying each
codec in depth. You can start by looking in Wikipedia until you get to
download and study the white papers of the codecs of interest. In any
case, you must then start a long experimental phase, trying presets
with different configurations or creating new ones, until you get
satisfactory results."
Perhaps the best thing is a document outside the manual but
downloadable from the site, like your "Preserving Camcoder Media.pdf,"
where you can accumulate all the data on codecs that users have
experienced.
I found this table:

I didn't really mean that Cineform should get a more specific
description than other codecs.
And of course, the CinGG manual has to delimit surrounding details, a
knowledge interested can find other places.
In addition to the table url above and wikipedia mentioned, here
follows url to the Cineform SDK

1) To sum up and add to my background references, I forgot we also had a
thoroughly discussion about Cin vs Cinx in 2021
So evidently more frequent repetitions is needed as getting older ;)
from this post by Andrea on, section:
2- I don't really understand the multibit version.Why put both the
regular version and the multibit version?
Are there things that work with one and not the other version?

2) Possibly I can make an update extension of my previous "Preserving
Camcoder Media.pdf," document included experiences from my ongoing DVD
project, but not before I have finished that.
Even though I don't plan to make a codec/encoder document, I still think
it would useful with an extensible table or list over "Supported pixel
formats" for each encoder of interest. This based on CinGG's internal
ffmpeg engine, which I don't think can be accessed by users from a CinGG
package or appimage, and which might be some different from the system's
enabled codecs and encoders(?)
By the way, this should not need to a longer document than a few of pages.
As an example using my own systems ffmpeg, a short encoders list (of my
current interest) could be
ffmpeg -hide_banner -encoders | egrep
"av1|x265|x264|mpeg2video|prores|cfhd|ffv1"
