[David Battistella] “Is it captured or digitized via firewire or imported. if it imported, where is it captured?
…..I though the Nitris was an 8-bit solution.
Why is the raw picture quality silly?
Is it because FCP is such an awful scaler?
Is the rendered media in FCP somehow inferior to the rendered media in an AVID product?
Just wondering what avid does to the picture to make it so much better.”
David,
DV25 is captured via FireWire and wrapped with an OMF wrapper to make it cross-platform compatible between Avid systems. DV50 and DV100 is captured via FW and wrapped as MXF. I think there are some pretty good multi-generational codec comparisons on Marco Solorio’s One River site.
I believe Nitris is a 10-bit YUV solution. It also handled 2K film files. I’m not saying that Avid’s image is better, rather that at its best, it isn’t worse, which is what you originally implied (or so it seemed to me). I use Kona 2 all the time, so I’m well aware of how good images via FCP can look. At their best, both companies put out excellent images.
My point about the scaling is that Apple does not have good scaling engines in FCP. This was specifically addressed in the FCP5 upgrade. As yet, I really haven’t had a chance to make any new comparisons. I have done that with Motion versus Red versus AE and wasn’t that impressed (with Motion’s quality on hi-res, highly textured stills). My point about raw images, was because this rarely happens. Images are scaled, color-corrected and effected in many ways. In these steps a lot of things happen to alter the image. For instance, many of these processes use OpenGL video cards. These are designed for game playback, so even though they may be pulling in 10-bit images, they frequently are writing only 8-bit images back to RAM.
What about YUV-RGB-YUV conversions? It’s all a pretty pointless argument. Frequently the “better mathematical” processes yield poor images. So for instance, Avid’s notoriously bad DVEs were Pinnacle cards. People objected to the fact that they tended to soften the image. In reality this was needed because the image filtering made the moves look smoother and softened textures, which would tend to scintilate otherwise.
Go look at the arguments on the Smoke forum. Smoke on Linux is an 8-bit box, but that’s 8-bit RGB. Is this better than 10-bit YUV? I don’t know, but Autodesk certainly thinks so and the images tend to bear them out.
