use linked monitors create to "montage'd" events

I'm not sure if this has been suggested before but it would be a pretty slick trick to allow linked monitors to create to create a single event consisting of the captured frames from the respective sources, in synchronized playback.

In other words, linked monitors would create events that playback just like we now 'montage' monitors in real time.

I have seen this in some commercial video surveillance applications that record continuously, not sure if it has been combined with motion detection though...

Thank you for the suggestion. This thought has actually crossed my mind on a couple occasions. but getting them to play back in sync in modect is the biggest challenge. Doing so with the monitors in mocord/record mode is not to tough though.

Yeah. I figured that would be the tricky part.

But, if you'll pardon my blissful ignorance of the voodoo you coders do, instead of trying to synchronize the playback of multiple sources, would it be possible to use your "magical scripting powers" to copy/combine the captured jpeg frames into a single jpeg frame, then playback those 'combo' frames as a single event? .

Granted, you wouldn't be able to switch between individual source views and the 'combo' view during playback, and I imagine generating the 'combo' frames would be something of a resource hog making it's practicality largely dependent on the hardware... you might even have to limit the options to 2, 3, or 4-source combos to keep it simple...

Yeah, I know. But it's so easy to say "Can't you just...." when you're a clueless mortal! I can't help it!! LOL!!

It would likely be such a resource hog that it would cripple all but very high end systems, You would be basically adding four more processes to add each one into a single image on top of whats already going on.
