Can you apply multiple filters at once in FFmpeg?

I’ve found out that yes, ffmpeg applies the filters in the order specified; thus it’s not a good idea to e.g. hardsub subtitles first and then apply sharpening filter, e.g. like this: -vf “scale=1920:1080 , subtitles=subtitles.ass , unsharp=3.0:3.0:1.5″(that’s how I found it out accidentally)– edison23May 17 ’18 at 14:59

Multiple options can be separated with a :, which means that any : have to be escaped (so use \\: ).

One work around to this is to use multiple ffmpeg instances running in parallel, or possible piping from one ffmpeg to another to “do the second encoding” etc.
