 Usefulness of Pixlet for FCP editing? - MacNN Forums
However, maybe if they made a way to convert DV to pixlet (as in on the fly conversion, so you don't even notice it), and pixlet were somehow easier to work with than the DV compression, you might have an easier time working with it while editing.
The downside is that Pixlet is handled by your CPU and DV is handled by a chip on your camera/deck/whatever.
Pixlet was developed so that Pixar could share high-quality playback among its people without resorting to a frame server or high-speed array.

 Pixlet properties
David G., To answer your queries, Pixlet is in the standard 10.3 release as a QuickTime codec that works with any Mac.
By the way, Pixlet compression (forward-encode) is likewise vectorized, and runs within an order-of-magnitude of the decode speed, so, say, several Full-HD frames/sec.
There is one other feature that is of interest for extreme-quality seekers; namely, Pixlet has a final stage output dither, to effect a virtual 48-bit color-CRT display, that is, animation essentially devoid of Mach banding due to the finitude of monitor colors.

Pixlet's file weighs in at 46Mb and took about 5 minutes to render out of FCP 4.

 FCP Edits Pixlet HD just like DV!! - The Digital Video Information Network
Another note, real-time effects are NOT available in FCP when editing Pixlet, but I really wasn't expecting them to be, I'm just amazed that for basically the cost of a new Mac, you can now edit HD real-time on the desktop without any additional hardware, and without having to go to a lower res proxy.
This editing pipeline works just great for me, the convertion from the.m2v file to the Pixlet file is a one step process using mpeg2decx, and I really don't mind going through that extra step to be able to edit HD quality in real time, it's a small price to pay.
One last point not to forget is that if you choose, you can also use Pixlet as your Offline or "Proxy"editing format, and I imagine that's exactly what the high end HD folks with their CineAlta's and Varicam's will do.

I mean, why should someone do video pixlet encoding, when there are other nice and fast encodings?
The most important thing is that Pixlet is a frame based encoding so you can run it forward and backward or randomly jump anywhere.
Basically all other encodings are tracking the changes from one frame to another so you cannot just get any frame you want from anystarting point.
