Couple of quickies … The manual suggests using Photo JPEG Syphon and then converting to H264, because Syphon doesn’t support H264 - but it does! Have I set up Syphon wrong? Also, any recommendations for a video conversion utility?
Hey there! That part in the manual actually seems to be outdated, since h264 recording has been supported since Syphon Recorder v18. I’ll be sure to remove it 
I personally wouldn’t be able to recommend a conversion utility, but maybe someone else can?
