r/handbrake

I've been trying to get a simple script to convert all files in a directory. It seems like it should be a basic thing to do, but I haven't found a guide that works. I'm using Bash on Debian, but if it could be done using inbuilt HandBrakeCLI functionality that'd be fine too.

I've tried:

for %F in (*.mkv) do HandBrakeCLI --all-subtitles --quality 26 --preset "Fast 1080p30" -i "%F" -o ~/Season\ 01/"%F"

But that gives me a syntax error: -bash: syntax error near unexpected token `('

(Transcoding into a subdirectory isn't necessary, but it seems easiest)

I'd like to simply take a 4K and encode it to a nice 1080p x264 mkv file with ac3 audio. I know I have to change the colour space to BT.709. Does anybody else do this this? And what tips can you help me with?
