Subtitle formats can seem pretty complicated. It may seem easiest to just choose whatever format is most popular or widely supported, instead of the one that’s just right for what you plan to do with the subtitles.

To help you make the best decision, we’ve compiled our recommendations for the best subtitle file formats to use based on your needs below, along with some Quick Tips.

Supported Subtitle Formats for Import/Export with Amara:

  • SRT
  • SSA (SubStation Alpha)
  • TTML (Timed Text Markup Language)
  • SBV (YouTube format)
  • DFXP (Distribution Format Exchange Profile)
  • VTT (Web Video Text Track)
  • TXT (untimed text transcript)

What are you planning to do with this video after subtitles are added?

Display subtitles with the video online:

If you’re using a different hosting site, check the support documentation for that site to see which subtitling formats they support.

Use subtitles in a video editing tool:

Editing Tool

Best Format

Final Cut Pro ITT
Premiere Pro CC SCC or a Final Cut Pro XML export
ffmpeg Sub Station Alpha
MacCaption WebVTT or ITT
Sony Vegas, Lightworks check software support documentation

Note – For Sony Vegas and Lightworks:

  • Many video editors only support manually creating title cards.
  • We recommend adding the subtitles with a different video editor on a separate step, or checking with the software’s support and community for recent features or unofficial add-ons.


Using other subtitling editing tools might erase some of the work you did on Amara. For example, editing subtitles in the YouTube editor gets rid of any top-positioning you might have done to subtitles made on Amara.

Always use a programming text editor like Notepad++, TextEdit (MacOS) or gedit (Linux).
