On Ubuntu 20.10, just:

To change font size: stackoverflow.com/questions/21363334/how-to-add-font-size-in-subtitles-in-ffmpeg-video-filterThe default appears to be 24, so just multiply that by whatever seems like a reasonable factor.

Note howver that .ass subtitle files can contain style information, which ffmpeg respects. Aegisub can produce and preview such styles, making .ass one of the best options.

Written in C#.

This worked well on 3.2.2 Ubuntu 20.10. Recommended.

First import video with:They don't have an aegisub executable without the version number. Amazing.

If you already have a subtitle file that you want to edit, then just pass it on as well:

Ctrl + P: play and pause video.

Ctrl + 3: set current substitle start time.

Ctrl + 4: set current substitle end time.

Enter: finish editing the current entry and start a new one.

Good shortcuts and user experience.

No waveform viewer: github.com/otsaloma/gaupol/issues/49 so unusable.

Not to be confused with Subtitle Edit.

As of 0.54.0 this feels featureful, but extremely buggy or lacking UI obvious enhancements that would be simple to implement, and offer huge value:

It is hard to understand how that project reached this weird featureful but crappy state. Feels like they just gave push permission to a bunch of random people.

A Microsoft format for flashing microcontrollers by copying files to a magic filesystem mounted on host, e.g. as done on the Micro Bit and Raspberry Pi Pico.

Revolutionary for its time, and a big part of Ciro's Enlightenment.

But too insane, and did not keep up with internet age, and so Ciro wants to kill it now.

LaTeX subset that output nicely to HTML.

Too insane though due to LaTeX roots, better just move to newer HTML-first markups like OurBigBook Markup or markdown.

XML, ain't nobody ever going to write that manually.

This is good software.

If it only it were written in JavaScript instead of Haskell (!?), then Ciro might have used it as the basis for OurBigBook Markup.

Ciro Santilli was contributing to this, when CommonMark left private mode and killed it, thus wasting many hours of Ciro's time.

CommonMark is a good project. But its initial release method was not very nice, they first developed everything behind closed doors with the big adopters like GitHub and Stack Overflow, and only later released the thing read, thus wasting the time of people who were working on alternative in the meanwhile, e.g. github.com/karlcow/markdown-testsuite which Ciro contributed to: Ciro Santilli's minor projects.
