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:
To set the video length, search for "set outpoint" on "monitor".
Add subtitles:
  • Effects
  • Dynamic text
then drag on top of the video track. To add only to part of the video, cut it up first.
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

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!

amazing.
On Ubuntu 22.04 haven't crashed yet.
