Burn in subtitles in the mkv container

[Phil Dicker]

Hi, sorry if this has been asked or is an easy task but I could not find any info. Also thank you so much for the program it is fantastic!

Is there a way to burn in subtitles that are already in the mkv containers? I have videos with srt/ass/ssa tracks and sometimes more than one in the container, like track 1/2/3/etc. I'd like to be able to select say subtitle track 1 from the container and burn it into the video during batch conversion. Is there a easy way to do this? Thank you :)

Hi, you can use the %ff dynamic variable to reuse input source in parameters field.
For example:

-map 0 -c:v libx264 -crf 23 -c:a copy -sn -vf subtitles=%ff:stream_index=0

You have an example in online presets
