Well, actually that video grabber you mentioned in your link, was the thing that started the whole idea for us. We did our first tests, the videos, app prototyping andwhatnot with it. Though LukiLink will be manufactured by the same company (Hint: it's not Pearl, they just resell it), we have our own custom made board inside (without going to deep into this here, but it has a lot to do with latency/lag, and some other parameters, which don't really mater for a video grabber, but for the main usees our product), and we also want to implement some features in the future, that would not be possible otherwise, like LUT upload to the device, an SDI option and some other stuff, which I can not talk about here, because of NDA. Also - if you look at the Kickstarter site - we have a female USB output connector implemented for us, not the fixed cable of the grabber. We made sure that both female connectors withstand the rough handling on set, and don't break as easy as the one of the video grabber (don't ask me how I know). That also makes a custom made housing necessary. Also we developed our own apps that will provide a ton of functions like peaking, waveform, markers etc. - also that grabber does only work with Android and not iOS.
