Settings in Syphon Recorder :
220×360 pixels
photo JPEG / quality : normal
15 fps
no sound
Each recording is during 8 sec.
During one day (8 hours) this video installation can be used by 100 to 200 persons for max 100 Mo.
So disk space isn’t an issue here.
@bangnoise : This weekend I’ll test the worklow on my MBP.
Thanks
