Ok so i got raylight and im using Premiere Pro 2.0 I filmed a sequence in 1080/60i but the quality is not very good...why is this? and how do i fix it
 
Run the raylight control program and choose "best" quality. You're probably running in medium or low quality mode (which gives fast performance, but lower picture quality).

If you're running the program in low quality mode, will that be the image quality you get when you export the video(unless you change the quality to "best")?
 
No, the quality setting is only for viewing and editing on the NLE, the real quality is that of the MXF the avi you're viewing\editing is associated with.

So what would that mean for me, a Premiere user with Raylight?

What it means is that the quality setting is just for convenience during editing or during viewing of the clips. It essentially "downsamples" the real HD quality clips to a "playable" quality for viewing in RT or close to RT. Upon rendering out the sequence in Premiere it renders full HD quality.

Does this help?
 
Yes.
Also, we found that on a 1080 60i clip Ray Light did something funny with the color. We finally found that you need to dompress the color space through After Effects and chop the ends off or you'll get REALLY muted colors. (Sort of like running audio through a compressor....but different).

Some of this could be our issue since we are just getting into the workflow, but we're pretty confident Ray Light is doing something to the solorspace on 1080i clips.

I'm eager to see what others are finding.

You do have to put it in Raylight Blue before a final render, though.

So you have to switch it to blue before a render? I didn't realize that. If you are working in the middle setting (yellow I believe) and building previews as you work,
and you switch to blue will it rerender all clips or does it pull the data from the previews that were in yellow? I ask because when changing Raylight Modes Premiere doesn't flag clips as needing rerendered on the timeline.

Thanks!

It's not really funny unless reading ITU-R BT 601 makes you laugh.

Raylight maps black to 16 and IRE 100 to 235. Superwhite
can go up to 255. This was chosen mainly to avoid clipping
but also to avoid banding in the blacks.

Most codecs will expect those values when encoding
RGB back to your final product, whatever that is, so I would
check it on an NTSC or HD monitor and not rely on
how it looks on the computer. Don't stretch it unless you are
publishing to the web or some other RGB format.

You can redo the previews by changing to Raylight
Blue, then in Premiere select Sequence->Delete Previews

I think this is in the ReadMe file, section 7.

I was doing that already to delete the preview files but I wasn't sure it was supposed to work like that.

Thanks!
