If there isn't other reasons against it, I will suggest to rename
the current preset av1.webm to av1_aom.webm
Good suggestion and no one has noted any reason not to. It is done in
GIT along with adding the 2 lines that make the rendered file seekable.
And possibly upgrade to svt-av1 v.2.1.
Agreed -- I started working on this on May 29, but had some trouble.
I will try harder!
I am still pondering the below information.
Transcoding regarding duration was also mentioned above.
My input file here was a cfhd transcoded with ffmpeg from a Prores 422
hq source video file (that is not a arbitrary cut).
Alt. 1)
Therefore I went back to my source Prores 422 (HQ) hd01.mov which
especially default includes 16 channels LPCM audio, even though only 2
ch stereo is used.
Loaded this Prores 422 hq source file into CinGG
1) Video only rendering - no error messages
Rendering to file /Videoklipp/Cineform/av1_aom_yuv422p10le.webm
File format; FFMPEG webm
Video only wrench: av1.webm | yuv422p10le

-----------------
Alt. 2)
Transcoded alt. 1) source input file to Prores 422 hq with 2 ch stereo
audio:
ffmpeg -hide_banner -i hd01.mov -map_metadata 0 -c:v copy -c:a
pcm_s24le -ac 2 hd02.mov
-----------------
Alt. 3)
Transcoded th source file Prores 422 (HQ) with LPCM audio to CFHD
quality 7 (high+), AAC audio (default) to stereo (-ac 2) and Metadata
(some)
ffmpeg -hide_banner -i hd01.mov -map_metadata 0 -c:v cfhd -quality 7
-ac 2 cfhd01.mov
By loading Alt. 2) Prores LPCM or Alt. 3) CFHD AAC with 2 ch stereo
audio into CinGG
1) Video only av1_aom.webm rendering caused the previous FFseek I/O errors
Especially that rendering Alt. 2) Prores with 2 ch audio caused FFseek
I/O errors confused me, because the video part was just copied from the
original Alt.1)
that worked fine.
2) Audio only hd02.mov stereo lpcm -> opus.webm worked ok
