Re: BBC test of 890

Ok, so here's a test. This was shot in 422 pro res HQ, and that's how it was uploaded. I can link a dropbox of the file if anyone wants it. I understand the light is low. We don't have a lot of lighting fixtures to work with, so it's primarily lekos... and even then we get a lot of requests to tone them down. Is the mistake, just not enough lighting? I didn't shoot this one, but I did check the camera before show time, and if I remember correctly it was 1.4f and 0 db of gain.


Well youtube kind of degrained it a bit, so here's a dropbox link too.

Mark, it's hard to see the noise with all the compression artifacts of youtube. Any other footage I've seen from the 800 series cameras has been very clean...especially given the sensors are 1/3".

What are you viewing your media on?

Re: BBC test of 890

Check out the drop box link right below the video. Can you not download it where you're at? Like what device do I see the noise in? I'm watching it on the 27" iMac I'm editing it on.

Anyway so we did a video shoot yesterday, and I took it off cinema gamma- and was able to add more light to the point where I could add -3 decibels of gain, and there still was a bit of noise on the blue drape.

I though about uploading it to Vimeo but they seem to have limits. And that video is larger than what they allow without upgrading.

Re: BBC test of 890

The blue channel will have more noise than the green or red channel, so that might be why you're seeing the noise in a dark blue curtain. You might try putting 1/2 CTB on your lights and white balance to that. I've been told that this will give a cleaner image.

Re: BBC test of 890

Ok, I'll try that. I seem to get some degree noise in just about any dark color or shadows on stage, so I'll try that. Whether it's blue or black.
