Subtitld For Linux

In today's world with all the streaming services at our disposal, the demand for offline videos, movies, or TV shows is understandably lower. The same can be said about subtitles.

Nevertheless, if you need to add subtitles to your videos, as well as create, edit, and transcribe subtitles, then might as well go for a specialized solution.

Subtitld is one such specialized solution, a free, open-source, and cross-platform application (works on Linux and Windows) that provides you with all the necessary tools for doing just that, creating, editing, and transcribing subtitles.

Here's what you need to know about Subtitld. For starters, it's important to note that Subtitld is capable of working with some of the most popular subtitle-related formats. These include SRT, SSA, TTML, SBV, DFXP, VTT, XML, as well as SCC and SAMI formats.

The app works with all types of videos, without a video time length limit. The GUI is pretty good and is fully adjustable to perfectly fit the size of your display.

At the core of Subtitld, we can find two frameworks/tools what need next to no introduction thanks to their popularity. The first one is ffmpeg which handles all the internal processes used for audio/video manipulation purposes.

Secondly, the app uses libmpv (or the MPV playback engine, if you will). Libmpv is one of the most powerful video playback engines out there.

The app uses PySide6 for the GUI, and the app's code is almost fully written using Python version 3 (which should make it very compatible with most of the modern Linux distros out there).

Working with Subtitld is somewhat of a combination of working with a simple video editor, on top of a fairly unusual text editor. The GUI allows you to adjust the playback speed without changing the pitch, set timecode parameters for repeated playback, open various formats (both video and subtitle), as well as adjust the start, duration, and end of a subtitle directly from the timeline bar.

That's not all. The app is also capable of slicing, meaning that you can merge to the last or next subtitle, or slice in the middle of the text cursor position. You can also add subtitles with editable durations (or remove selected subtitles), benefit from up to 20 levels of zoom (which should enable finer editing), as well as from the grid system (that shows a grid in order to help you better visualize your projects by frames, seconds, or scenes).

There's also a file history feature (that allows you to open files from a list of recently-used entries), a undo and redo feature (with unlimited actions), as well as a series of default keyboard shortcuts that will improve your productivity.

Subtitld is definitely one of the most well-designed apps of this sort out there. What makes Subtitld so special is not only its amazing set of tools, not the nice GUI, but the fact that it allows you to edit subtitles directly while also being able to perfectly sync them with the video at hand and preview the changes in real-time.
