DVFilm RAYLIGHT is here

Hey there is also us, laptop users here... I wonder if we will see a P4 prossecor close to 5ghz sometime soon :(
 
wow, wait a minute here... so intel's P4 840 Dual core (1MB X 2, 3.2 GHZ, 800MHZ FSB) is like a 6.4 MHZ machine ?????????

Yes the Core Duo processors are dual-core 2Ghz so X 2 is about 4Ghz machine.

Unfortunately, having two processors doesn't necessarily make your computer twice as fast... every piece of software from your NLE to the plugins you are using have to be optimized for multiple cores for you to get full use of both processors... otherwise it just runs at single core speed with the other core(s) available for multitasking.

dual-thread or even quad-thread, but how many of us have
multiple processors?

My guess would be 75% or more of HVX buyers will have HT, Dual Core or Dual CPU processors. I would make this priority #1.

if software isn't optimized for multiple cores, does the OS at least have each piece of software spread out over the cores as a whole? Like, if I was running 2 simple programs and FCP, would the mac put the simple ones on one core and FCP on the other?

Any 720 or 1080 24fps MXF available for testing?

Previewing out, it gives me 21-22 fps.

I assume you're previewing in SD?

From what I've read, this plugin doesn't make AVI "copies" of the MXF data, but rather "reads" them in realtime and allows you to work with them in lower-quality form without reducing the quality of the actual files? Kind of like a proxy setup? If that's so, that's awesome... I might even reconsider getting a Mac if it works as well as the website seems to indicate. They mention that Raylight uses its own codec, however; does that mean it's recompressing the original files, or are you able to edit the files and output them untouched from the original DVCPRO-HD data?
 
That is a superb question! You also described what I thought Raylight do but wasnt 100% sure about. I hope we get an answer equaly awsome !

So far, I can't tell. It does make copy files, and you can't move the original files, so I wouldn't be surprised if it's a proxy setup.

How it renders, I can't say as of yet. I know the rendered files are very high-quality.
 
Raylight will support 1080 50Hz format in the coming weeks

Raylight is what you might call a transparent proxy. The avi contains a low data rate copy of the frames (for Raylight Red), a link to the original frames in the MXF files, and the audio. When you switch from Red to Yellow or Blue, the codec automatically draws data from the MXF files instead of using the Red copy. The beauty of it (for a programmer anyway) is that the editing system actually hands the codec the link to the hi-res data on the hard drive because it is imbedded inside the lo-res image, kind of like a jpeg virus.

Raylight can be used for non-recompressed editing, so the output AVI is just a rearranged version of the original frames from the camera. Or you can also recompress to DVCPROHD or any another format.
 
Thanks mvb.

I am going to buy Raylight with Vegas, but I want to try the demo with some 720/24P clips first.

I can't find any 720P HVX200 MXF files.

One area that I wasn't sure about and has me a bit concerned is the "Don't move the files" restriction. I understand why they can't be moved (the raylight files won't find them) but I don't see why you can't move the whole set of files without having to re-run Raylight to re-process the files. If you move the Raylight and original file together it should know where to find it. Moving files happens all the time and this could be a workflow issue.
 
A codec's not privy to the file location, it only sees the frame data which may have been created days or months before.

Probably we'll provide a way for RayMaker to quickly update the pointers in the AVI if the files have been moved, which would maybe take a few seconds per clip.
