RE: [Avid-L2] Re: OT: Best ways to confirm a noisy image...

Sorry Terry, I didn't mean to imply that the JVC was a grade 1, my grade 1 is a Sony BVM CRT, I was just listing the monitors i'd viewed it on. It was, however the only monitor i had available that would show the image at its native resolution without having to take a downconverted feed. I have access to a Tek WVR-7000 so i will try what you suggest, that's just the kind of tip I was looking for, I was hoping there would be some kind of vectorscope magic I could make use of! And thanks to you John for your info on why the blue signal is more noisy, I'm learning all the time.

Cheers,

Andi

Grade 1? What does that really mean?

Don't take offense please, I was one of the first to say the JVC was the best bang for it's buck at the time it came out. But that was a while ago, and I still hung on to my CRTs as the LCDs (including JVC) weren't good enough, especially in the blacks.

<<Other than by pure visual inspection and a monitor just showing the blue signal are there any other ways to test for noise in an image?>>

Yes. Take a still from the original source, and a still from the final master, comp them both in photoshop and use "difference" to see what has been added in the noise.

If you don't have the original, look on an external vectorscope, and magnify it. If the signal shows a bunch of blocks, that is digital 'noise" or compression artifacts.
