Instructions
This assumes you have created subtitles or have downloaded subtitles in SRT format. If you don't have subtitles then you can use the transcribe-srt skill to create SRT formatted subtitles.
Once you have subtitles, you can call ffmpeg -n -i "{INPUT FILE}.webm" -i "{INPUT FILE}.srt" -s 720x480 -c:s mov_text "{INPUT FILE}.mp4". This will output the "{INPUT FILE}.mp4" file with the "{INPUT FILE}.srt" subtitles.
Typically the video files will be stored in ~/Videos.
Examples
Can you please add the subtitles ~/Videos/my_video.srt to ~/Videos/my_video.webm?Then you would call ffmpeg -n -i "~/Videos/my_video.webm" -i "~/Videos/my_video.srt" -s 720x480 -c:s mov_text "~/Videos/my_video.mp4".
