Please make inexpensive HDSDI recorder

Keith Wakeham · June 7th, 2005, 06:51 AM

SataII isn't to worrying, there are ways to translate parallel ata to sata, and sataII is backwards compatible with sata I.

Personally, I'm still pretty amazed at the lack of modes (well, desirable modes anyway) that companies are putting in cameras. The funny thing about all formats for hd (both 720 and 1080 resolutions) is that the number of pixels are exactly the same. Not active pixels, but all the pixels, the datarate still is identically based on 74.25 Mhz for ever HD format. Why do they keep giving us 720p and saying progressive is better than 1080i when there are just as many 1080p modes defined as their is 1080i.

It really means they are holding back, but the worse part of it means that something like an uncompressed recorder becomes less useful since were stuck with half the resolution if we want progressive, but twice the framerate, or the right resolution but interlaced. The funniest thing is that if the sensor can do 1080i@ 60 fields, then it is able to do 1080p @ 30 frames because the sensor still runs the exact same frequency.

Interesting.

Looks like VIA is still progressing there low powered processor game.

Keith and Radek, yes I think they are holding back so they can charge more for their production cameras.

Wasn't aware of that thread John. I don't know how complex cineform is, but likely would require a lot of work to make it into a small device or the always unpopular full computer approach would work.

I think the new Via C7's are great processors and would be awesome for certain applications. Personally, I don't have clue how they could be intergrated, its definetly possible. I do see some other uses for the processor, but most of my ideas fall to the general purpose applications.
