Is the team of Telestream aware of this issue?Quality is dependent on source and encoder settings. We'd like to evaluate but you need to provide complete technical settings and source types and possible visual examples so we can examine and help resolve this. Please describe as if you wanted to us to do the exact same thing on our computer.

CraigS Hi Craig, this is my set up, export settings, and sample HEVC result. Thank you!
-
Robert ScreenFlow isn't yet fully compatible with Apple Silicon and doesn't perform very well under Rosetta so it's possible that impacted the encode quality.
Canvas size and exported frame size (is it the same as the YouTube video?) are factors as well since scaling might be impacted as part of the compatibility work we're doing. -
CraigS My Mac is Intel based and not Apple Silicon. Also it doesn’t use Rosetta.

CraigS The clip is scaled down to 1080p.

CraigS When I use MP4 (H264) for export then everything is perfect. However using HEVC provides terrible results. Any idea? Thanks!

Robert ScreenFlow has Big Sur issues as well. That flickering and stuttering I may have seen before. Our internal reference FLOW-6996 HEVC shows jumping and stuttering.

Can you link to the same as an H.264 encode so I can show the engineers a comparison? -
CraigS H264 1080p settings
