he came up with some answers for the new Updowncross HD that are not in the manual. The email response was forwarded to me from the Product Manager.
my question was specifically in regards to what happens when the unit is converting from 1080i50 to 1080p50:
A: "It’s de-interlaced to 1080p25 so no loss of fields and then doubled to 1080p50. "
My second question was "if its therefore de-interlacing, what method is it using?"
A: "In this case we are basically doubling the number of fields so you could call it “Progressive Scan”.....engineering say that the method used for the Updowncross HD in this instance would be closest to "Weave""
this is a really interesting product! Darrell tells me its flying off the shelves and they cant keep up with production, there is over 1 month backlog at the moment for stock. Im not surprised. Its a hardware box that deinterlaces using TERANEX algorithms for $200 bucks.
it does sound like the video is going to be jumpy tho? its dropped from 50 fields/second to 25fps. that causes jittery scrolling I would have thought?

Yeah, that reply from BlackMagic makes no sense.
usually that's exactly what I suspect as well...artifacts and lack of smooth video. Plus... I agree jagabo that it makes no sense.
It was in an email in writing from them too...its not like I translated it wrong over the phone or something!
