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"
  V....D libaom-av1           libaom AV1 (codec av1)
  V....D librav1e             librav1e AV1 (codec av1)
  V..... libsvtav1            SVT-AV1(Scalable Video Technology for AV1) 
encoder (codec av1)
  V....D av1_nvenc            NVIDIA NVENC av1 encoder (codec av1)
  V..... av1_qsv              AV1 (Intel Quick Sync Video acceleration)

  V....D av1_amf              AMD AMF AV1 encoder (codec av1)
  V....D av1_vaapi            AV1 (VAAPI) (codec av1)
  VF...D cfhd                 GoPro CineForm HD
  V.S..D ffv1                 FFmpeg video codec #1

  V....D libx265              libx265 H.265 / HEVC (codec hevc)
  V.S... mpeg2video           MPEG-2 video
  V..... mpeg2_qsv            MPEG-2 video (Intel Quick Sync Video 
acceleration) (codec mpeg2video)
  V....D mpeg2_vaapi          MPEG-2 (VAAPI) (codec mpeg2video)
  VF...D prores               Apple ProRes
  VF...D prores_aw            Apple ProRes (codec prores)
  VFS... prores_ks            Apple ProRes (iCodec Pro) (codec prores)
  A....D wmav1                Windows Media Audio 1


and some selected encoder's "Supported pixel formats"

ffmpeg -hide_banner -h encoder=cfhd | grep "Supported pixel formats"
     Supported pixel formats: yuv422p10le gbrp12le gbrap12le

ffmpeg -hide_banner -h encoder=mpeg2video | grep "Supported pixel formats"
     Supported pixel formats: yuv420p yuv422p

ffmpeg -hide_banner -h encoder=libx265 | grep "Supported pixel formats"
     Supported pixel formats: yuv420p yuvj420p yuv422p yuvj422p yuv444p 
yuvj444p gbrp yuv420p10le yuv422p10le yuv444p10le gbrp10le yuv420p12le 
yuv422p12le yuv444p12le gbrp12le gray gray10le gray12le

ffmpeg -hide_banner -h encoder=libsvtav1 | grep "Supported pixel formats"
     Supported pixel formats: yuv420p yuv420p10le

terje at localhost:~> ffmpeg -hide_banner -h encoder=av1_qsv | grep 
"Supported pixel formats"
     Supported pixel formats: nv12 p010le qsv
