Some of you may have noticed, that the videobitrate is kinda low for 1080p video (around 12Mbit/s).

I've found a gstreamer preset file where we can change this. 24Mbit was too much, I tried upto 20Mbit/s which seems to work without framedrops. I tried changing framerate (at 30 currently) and audio bitrate (AAC at 128Kbit/s) too, but failed so far.

All you need to do is change in the following file:

/usr/share/jolla-camera/presets/GstOMXMPEG4VideoEnc-omxmpeg4videoenc.prs

the line:
target-bitrate=12000000

to the following:
target-bitrate=20000000


Maybe someone else with more gstreamer knowledge can dig more options out of this.
