Kdenlive A. I.  speech recognition subtitles
Channel: Solve Computer Science
Date: 2023-10-18

The Kdenlive FOSS video editor offers the possibility to add subtitles on a separate track using the Whisper speech recognition FOSS.

In this video we'll see how to set up the environment having Kdenlive installed as a flatpak package.

I tried several times, and after trial and error it worked in the end.
