adding captions/subtitles to a video

Facebook accepts video captions in the SubRip (.srt) format. [how-to] [file format]

Some tools that I've used to help me add captions to a file:

• HappyScribe.com — a speech-recognition tool that can generate .srt files
  • it's a relatively inexpensive pay-as-you-go service
• YouTube has a free voice-recognition service
• (TODO — other voice-recognition services)
• Handbrake — can render subtitles onto a video itself [how-to]
  • can import .srt files, among other formats
  • the feature "burn in" means to overlay the text permanently as part of the video; also known as "hard subtitles" as opposed to "soft subtitles"
  • if you want to change the burned-in font settings, it's pretty tedious, but it can be done by modifying the .srt file like this

If you're wondering the question "Does Shotcut support rendering hard subtitles?", unfortunately, the answer is "no". You'll want to use an external tool to do this.
