Bug ID: 467842
Summary: Screencast output looks very poor, likely from
bad/non-configurable default settings
Classification: Applications
Product: Spectacle
Version: 23.03.80
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: m...@baloneygeek.com
Reporter: mira...@mirandastreeter.com
CC: k...@david-redondo.de
Target Milestone: ---
SUMMARY
When attempting to use the spectacle screencast feature, the output looks
awful. I believe this is due to poor capture defaults.
STEPS TO REPRODUCE
1. Open wayland session
2. Open spectacle
3. Record screen (window, workspace, etc)
OBSERVED RESULT
You can see the attached video as an example. The same issue still occurs if I
pick a smaller region. From what I can see the bitrate is arguably higher than
necessary, and defaults to a variable framerate with what seems to be some kind
of ABR-like rate control. Something also seems wrong with the color range,
maybe?
EXPECTED RESULT
A default of, or at least an option for, a constant framerate with some form of
CRF that can be tuned.
