Correct me if I’m wrong, but it appears to me that when playing video in a boygroup setting, that in effect “sync” means “within one second of each other”. I’ve worked in video for decades, and this is the first time I’ve heard “video sync” to refer to anything other than “frame”.
Am I missing something? I find it hard to believe people are using this in places with multiple systems playing a video where parts of the composite display can be up to a second out of sync with each other. And yes I know you can set the tolerance to below a second, but trying to get it within any reasonable concept of “sync” results in the systems thrashing doing constant seeks.
The problem can be seen quite clearly here:
where the first video (coral reef) is synced pretty well, but the jet fighter one is painfully out of sync (the whole display of 21 monitors is running on four boygrouped PCs, in this case using the VLC player node). As the videos cycle, it is pretty random how well they sync up, and I have tried all sorts of tricks to make sure starts were sync’d, pre-searching was done and waited for on all boxes, etc. etc. etc.
