Combine two ffmpeg commands to encode, watermark, and subtitle a file

  • 772

How to integrate these two commands so I only need to run one?

I want to add watermark, encode the quality and add a subtitle all with one command.

Encode and watermark:

ffmpeg -i video.mp4 -i watermark.png -filter_complex "[0:v]scale=640:360[bg];[bg][1:v]overlay=10:10" -tune psnr -refs 3 -c:v libx265 -preset veryslow -crf 33 videofull.mp4

Add subtitle:

ffmpeg -i video.mp4 -filter:v subtitles=text.srt videosub.mp4

How can I combine the two?

command-line

    ffmpeg -i video.mp4 -i watermark.png -filter_complex "[0:v]scale=640:360[bg];[bg][1:v]overlay=10:10,subtitles=text.srt" -c:v libx265 -preset veryslow -crf 33 videofull.mp4

    Filters in the same linear chain are separated by commas, and distinct linear chains of filters are separated by semicolons. See FFmpeg Filtering Introduction for more info.

    I removed -tune psnr -refs 3 because psnr is detrimental for general encoding and refs should be covered by the preset.
