I should hope I could report progress, but sorry - it's the same 
immediately error with av1_qsv.webm

localhost:/home/cinelerra/cinelerra-5.1
# ls bin/ffmpeg/video/av1_qsv*

Error rendering data

Message log:

Render::render_single: Session finished.

Another question I wondered about from yesterday:
"you can change loglevel to debug in bin/ffmpeg/encode.opts too, it will 
produce bugger log, hopefully with more detailed error msg."
-------
localhost:/home/cinelerra/cinelerra-5.1/bin/ffmpeg # cat encode.opts
# apply at init encode
#loglevel=error
loglevel=debug
threads=auto
side_data_only_packets=1
----------------
As I understood this, the loglevel=debug is setup in Cingg's internal 
ffmpeg, to "trigger" debug error messages from the external system ffmpeg(?)
How does communication work, and did it report more detailed error msg."
