Matt,
I actually suggested incorporating MPEG encoding into your products a number of months ago on this forum and also emailed it to your general email address. I received a reply that it would be mentioned to the development team, but it may not have made it through to you.
If your not familiar with Mainconcept, here’s what I know…
Some of Mainconcept’s PC packages allow for realtime encoding over from FireWire and other inputs, but according to the first poster, not from a DeckLink card. The Mac version of their standalone software does not support realtime streamed encoding at all.
The nice thing about Mainconcept is that they have a SDK that you could license available for both the Mac and the PC. Their encoding is supposed to be of high quality and capible of real-time on most faster machines. You may want to talk to them at NAB and consider licensing the SDK to add this capibility to your products. I think it would be a valuble addtion or option for your cards.
