I tried another videocamera, another HDMI cable, finally I upgraded to beta 10 without improvement… Still frozen frame.
2) I succeed with the settings with the Billboard and the “open GL scene”, and could see the video stream both in Syphon preview window and QC viewer; BUT still got a frozen image with sound when recording…
So, at this time, it was only preliminary testings, right now I’m working on the narrative side of this project. When it will be time to work on the computer side, I’ll probably come back here and ask for help.
So, thanks again, for your help and your work,
