SubViewer 4.0.6

SubViewer is a veteran Windows subtitle editor that pairs a text editor with a small video player, so you can time captions against the picture.

David Dolinski first released it in 1999, and the copy here dates from 2013 with no updates since.

It may still run, but Subtitle Edit and Subtitle Workshop Classic do the same job today and are still maintained.

What SubViewer Actually Does

You load a video and its subtitle file, play the clip, and adjust when each line appears and disappears. The video side is an embedded Microsoft ActiveX media player, so it only plays what Windows itself can decode.

It reads the common text formats of its day, including SubRip (.srt), SAMI, SubStation Alpha, MicroDVD and its own SubViewer .sub format. It can also open lyric files synced to music, the kind karaoke software produces.

SubViewer took off after the DivX media player added support for it, and it was written alongside SubRip, the companion tool for pulling subtitles off DVDs.

The Program Versus the Format

The SubViewer name lives on mostly as a subtitle format. YouTube added support for SubViewer and SubRip files in 2008, which let existing videos get captions after the fact.

You do not need this program to work with that format. Any modern editor below opens and saves it alongside dozens of others.

Who Can Still Use It

It makes sense if you have old projects built in SubViewer, or you simply prefer its bare-bones layout on an older PC. The download is a small zip, so it is easy to try and easy to remove.

The tell that it is the wrong tool is a modern video file. If your clip is HEVC or AV1, or your subtitles are styled .ass files, the built-in player and editor will struggle where current tools do not.

What to Use Instead

• Subtitle Edit is free and open source, fixes out-of-sync timing and converts between hundreds of formats. It is the closest modern match.
• Subtitle Workshop Classic is a lighter Windows editor with a video preview. It feels the most like SubViewer.
• AutoSubs writes subtitles for you from the speech in a video, on your own PC. Use it when you have no subtitle file at all.

Once the file is ready, any player with built-in subtitle support will show it. VLC Media Player and MPC-HC both load a same-named subtitle file automatically.

PotPlayer goes further with fine control over subtitle fonts and timing during playback.
