PRS (Pre-Rendered Subtitles) is a format for storing image-based subtitles.

Currently PRS only supports PNG images.

Pros of PRS:

  • Ability to store any kind of graphic
  • Even advanced effects can be included as softsubs
  • Harder to "steal" than text-based softsubs
  • Images can be re-used and combined in various ways
  • It's very easy to port

Cons of PRS:

  • Hard to modify
  • Usually needs a tool to generate the files
  • Requires more space than softsubs and might require more than hardsubs

PRS filter is coming. Currently fixing: Seeking. Guess who you should blame for the delay?
