Tero Subtitler

Tero Subtitler is an open-source app focused on subtitle editing, synchronization, and review, featuring an interface that allows you to work with the text and video playback at the same time. In this way, you will be able to verify at all times that your work is being synced correctly.

Edit and review subtitles alongside the video

The interface's layout makes it easy to check every change on the movie or series you're working with. In addition to correcting audio-text mismatches, Tero Subtitler allows you to modify the font and alignment, use grammar correction tools, compare different subtitle sets, and automatically generate transcriptions.

Work with dozens of formats

This program supports more than 20 subtitle formats, including SRT, SUB, TXT, and XML. You can also upload videos in common formats such as MP4, MKV, AVI, and MOV, making it possible to combine all kinds of video and subtitle files stored on your computer. Once you finish editing, you can save the result or export it to other formats, including MP3 and SUP.

My experience with Tero Subtitler

I don't work with subtitles professionally, so many of Tero Subtitler's features fall outside my usual needs, but it still seemed to me like an incredibly practical tool for specific tasks. For example, it makes it much easier to correct those annoying discrepancies between image, sound, and subtitles that sometimes appear in movies and series.

The best and worst of Tero Subtitler

• What I like most about Tero Subtitler is the freedom to work with a huge variety of video and subtitle files without having to convert them first.

• What I like least about Tero Subtitler is its interface and toolset, which might be a little too advanced for most users.

Tools for both simple and advanced projects

Tero Subtitler combines both basic correction and synchronization features with more specific options for those who regularly work with subtitles. Download Tero Subtitler for Mac if you want to edit, review, and convert this type of file from a single program.
