@spitsyn.andrey:

Thanks for the script file. Give me some time to ask GG if there is a way to add this to the shell commands to let you do this inside of Cinelerra. The limitation of passing the filename is the problem. When gg added {cinelerra_path}/doc/RenderMux.sh he saved the variable name used from the Render menu, but in this case that is not available obviously. Maybe he can save the last loaded filename and use that. I will see what he thinks. Phyllis

Here the script file:

#!/bin/bash

filename="$1"
fileout="${filename%.*}"
proxy="6"
# Hardware encode AMD
ffmpeg -threads 2 -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i "$1" -c:v h264_vaapi -vf "format=nv12,hwupload,scale_vaapi=iw/'$proxy':ih/'$proxy'" -vcodec h264_vaapi -preset fast -c:a copy -bf 0 -profile:v 66 "$fileout".proxy"$proxy"-mp4.mp4
