Ciro Santilli This seems like a decent option, although it has bugs coming in and out all the time! Also it is quite hard to learn to use.
To get started:
- import a clip
- drag it onto the track area
Shortucts:
- Shift + R: cut tracks at current point. You can then select fragments to move around or delete.
- Shift mouse click drag: select multiple clips: video.stackexchange.com/questions/21598/select-range-of-clips-in-kdenlive
To set the video length, search for "set outpoint" on "monitor".
Add subtitles:then drag on top of the video track. To add only to part of the video, cut it up first.
- Effects
- Dynamic text
Preview has no sound on Ubuntu 20.10. Fixed as of Ubuntu 22.04.
Sound worked on Ubuntu 21.04 though, but it then soon crashed with:
= = SET EFFECT PARAM: "rect" = 0=1188 0 732 242
MUTEX LOCK!!!!!!!!!!!! slotactivateeffect: 1
// // // RESULTING REQUIRED SCENE: 1
Object 0x557293592da0 destroyed while one of its QML signal handlers is in progress.
Most likely the object was deleted synchronously (use QObject::deleteLater() instead), or the application is running a nested event loop.
This behavior is NOT supported!
qrc:/qml/EffectToolBar.qml:80: function() { [native code] }
KilledOn Ubuntu 22.04 haven't crashed yet.
Ubuntu 23.04 broke the clip drag and drop!
Worked on Ubuntu 20.10.
The UI is a bit too buggy to bear.

The default appears to be 24, so just multiply that by whatever seems like a reasonable factor.
ffmpeg -i input.mp4 -vf "subtitles=subtitle.srt:force_style='Fontsize=64'" output.mp4Note 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.

This worked well on 3.2.2 Ubuntu 20.10. Recommended.
First import video with:
They don't have an
aegisub-3.2 ourbigbook-parent.mkvaegisub 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:
aegisub-3.2 ourbigbook-parent.mkv ourbigbook-parent.assCtrl + 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:
- fundamental not defined out of box, e.g. Tiny forward/backwards. You can define them yourself, but they should be provided.
- github.com/SubtitleEdit/subtitleedit/issues/4976 can't export SubRip?
- can't interact with video on waveform?
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.
