4k idea

I was just thinking, if they made a codec you could capture 4k like HD is to HDV, you might be able to compress a 4k Image down to DVCPRO file size. Like HD is compressed to roughly DV file size with MPG2 Compression it might be easy to make a codec similar for 4k editing, just a though, not on camera but a capture codec.
 
Unfortunately, that wouldn't work. If you used an interframe codec with a 4k image, the processing power required to edit in real time would be out of this world.
 
Yep, you'd have to wait for something like 2008 until you can edit highly compressed 4k with your home computer. Most of us will not even have a 2k camera by then...
 
I don't know why you couldn't do 4K, you'd just need a multiple dual core processor machine. Only problem is that Windows Vista is a little ways off and Windows Server 2003 isn't good for NLE's. If Apple could release a 4-way dual core Mac, a true quad processor machine, then you'd be in good shape but your wallet would be...well...dead! =)
 
That's not really what I'm saying.

What I'm saying is that editing 4k MIGHT be possible with a fast RAID array and a top of the line computer. With an intraframe codec, of course.

With an interframe codec, however, you would need a ridiculous amount more speed for perhaps 4 times the efficiency. So you might not need the RAID array, but it wouldn't matter; no computer could edit that footage, or even come close.

So what I'm saying is that HDV is harder to edit than DVCPRO HD, so a interframe solution for 4k would be much worse, not better, than an intraframe one, despite larger file sizes.
 
Yeah, in that case, you'd be right. A lot of the time it isn't the speed of the computer that counts, but it's the quality of the coding for the codec.
