avidemux too slow

It’s better use (one of) the following codecs for encoding

  • x264
  • libavcodec MPEG-1/MPEG-2
  • libavcodec MPEG-4
  • Xvid 

so Avidemux will be able to optizmize the CPU usage and will be much faster. And the CPU temperature will be lower.

speech to text in Linux con KDE connect

If you cannot speak-to-text directly from the smartphone to PC, you can before dictate a text within KDE Connect and then, after, send it to your PC (provided that your smartphone and your PC are both connected with KDE Connect):

KDE Connect (on smartphone) – > remote input -> small icon on high, as below

Then choose as keyboard, Google Voice Typing

Then you will be able to dictate your text (seeing it, before, on the smartphone [KDE connect] screen) and send it to your Desktop device.
