This is a test video to see how the 10 bit web M video format fares on You Tube. I uploaded this for my own appraisal initially, but thought my gentle viewers would find it interesting.
My first perception of the video is that the colours are more accurate. Comments from viewers welcome.

For those interested in the settings:

GoPro Hero 11
Recorded in 10 bit , high bit rate
Colour:flat
Sharpness: low
Sound: standard .mp3 @ on125 Kb/s video track
50fps
shutter: auto
ISO: auto

Shotcut settings
profile: 10 bit AV1 WebM
(All other setting not listed below were left at standard for the profile).
Deinterlacer: Lancos
50fps
Quality: 85%
GOP: 25
B frames: 2

sharpen: Amount 50, size 50
colour grading: Midtones (Gamma) +16%

Sound: libopus @192 Kb/s (I left it at the standard setting). I recorded a.separate low processed .wav file on the GoPro, but found that the recording level is too low to use, even when boosted to +24 Db gain. If a viewer has any ideas why this is so, I'll be grateful.

I also noticed no banding when colour grading.
