Our verdict: Subtitle Workshop is still a quick, lightweight way to fix timings, convert formats and clean up errors in text subtitles. Its error marking and CpS display remain useful. The catch is age: the last release is from 2013, so it lacks waveform editing, speech recognition and modern format updates that Subtitle Edit offers.

About Subtitle Workshop

Subtitle Workshop creates, edits and converts text-based subtitle files. It reads and writes over 60 formats through its Subtitle API library and can also save to a custom user-defined format. Version 6.0 was based on the classic Subtitle Workshop 2.51 and added a toolbar, a pause and characters-per-second system, a multiple tags mode and a new error marking system.

Tools cover automatic durations, smart line adjusting, spell checking, FPS conversion, search and replace, and detection of timing and text errors. An integrated player previews subtitles over any video the system has codecs for, and a translation mode shows the original next to the translation. The current version, 6.0b, was released in November 2013 under the GNU GPL v3.

What it does well

  • 60+ subtitle formats. Opens, converts and saves SRT, SSA, MicroDVD, SubViewer and many more.
  • Timing tools. Automatic durations, FPS conversion, delay shifting and pause adjustment.
  • Error checking. Marks overlaps, too-short pauses, too many CpS and other problems.
  • Video preview. Plays video with the subtitles on top, including full-screen mode.
  • Translation mode. Edits the original and translated text side by side.

Who it is for

Good fit

Translators and hobbyists who need a light tool for timing fixes, conversions and error cleanup.

Look elsewhere

Users who want waveform-based timing, speech-to-text or OCR of image subtitles; Subtitle Edit covers those.
