Not sure if this has been posted in the forum, but here is the BBC test of the 890.

Thanks Scott--it's good to get an engineer suggestions on setup for the 890 and presumably the 850.

The 850 is really the best JVC camera they have produced in my opinion and also the 600/650
I'm about to add these into my kit.

I agree, the new cameras are a definite improvement over the 700 series. I'm thinking about an 850 to replace my 700...but the trend towards large sensor and 4k has me thinking twice. Maybe I need both;)

The test of the 890 by Mr. Roberts is encouraging. I was impressed by the dynamic range and low noise results, and the fact that the 800 series cameras are 2 stops faster than my 700...that would be handy.

My only worry is going from CCD to CMOS and the associated issues. I shoot with CMOS cameras all the time without issue, so I need to get over this.

Thoughts?

2 stops faster? So the 890 my station is getting me soon will see at night at 0db what it takes my current 790 12db to see? f10@2000 vs f11@2000 isn't that big of a difference. My Panasonic SPX800 was f13@2000, and had about a 9db advantage side by side with my 790 in testing.

I rate my 700 at about f5.6 or around ISO 200-250(1080 30p @ 1/60th). I found 9db was the maximum gain I would use, anymore is too noisy.

BBC needs 50mb/sec minimum right?

BBC needs 50mb/sec minimum right?

It depends on the "tier." For journalism, "tier 2," which is under 50mbps, is accepted.
For bigger productions, like documentaries and narrative shows, 50mbps is the minimum requirement. Of course, if it's like in the US, there's always exceptions.
And BBC now conforms to EBU's standards.

BBC needs 50mb/sec minimum right?
And as long as a long-GOP codec - if I-frame only it's 100Mbs.

Otherwise it's as Glen says - 50Mbs for main stream programming, 35Mbs for news.

(If the programme requirements are generally for 50Mbs, lower category material can be used for a limited amount - but is classed the same as Standard Def and archive. A case has to be made if the total amount of these is more than a certain percentage.)

We purchased the 890 earlier this year for in house video recording of events. It's a nice camera but the stock 20x lens we exchanged through our dealer for a 17x. The low light performance of the 20x isn't great, and I'd rather sacrifice OIS and get better low light performance. Although the OIS of the 20x did work well, but most of the time the camera was fully zoomed and 3.0f is unacceptable inside a dimly lit hotel ballroom. I'm still trying to get the noise under control in the blacks though- so maybe I need to shoot in standard instead of cinema gamma?

The kit lens is a good lens I'm sure, but loosing 2 stops at the tele end is too much. As for gamma settings, try the standard gamma with a bit of black toe compress, it should give you more contrast and lower noise.

I'll try that. I'm a bit unhappy with the noise I see in dark clothing- but skin tones and lighter clothing are always nice and clean. Yeah, losing two full stops at zoom was a killer for us. The 20x was nice, but I prefer a faster lens, with just a touch less zoom.

If the cine gamma is the same as the 790, then you will probably see blacks get very deep compared to standard. Obviously this is meant to bring down the whole image to decrease noise, but it seems to require a LOT of light.

Also, on my 790, as you slow down the shutter speed (1/30 vs 1/60) or gain up considerably, the 790 (890 too?) the blacks are brought up a bit. I find level 1 black compress button puts them back in their place nicely.

I'm surprised that you're seeing that much noise, the EBU test report seems to suggest it's a clean image for 1/3" sensors. Mr. Johnston at HD Warrior raved about how clean the camera is.

Mark, can you post a sample?

Yeah I'll see what I can do. Most of the stuff is at work on a Hard Drive. I have a few streaming samples I can link, but it doesn't show the noise I get sometimes in lower light. Mind you, we are primarily a hotel AV company, and because we have only basic source 4/ leko lights to work with, and low ceilings in our ballrooms, we often have to compromise by setting the lights on 10 foot poles- and we are often forced to use un-diffused lekos as our lighting- because we often use projection (light can't bleed onto the screen). That and we have to comply with those who say the lights are too bright and turn them down. I'll need to upload a sample tomorrow that hasn't been compressed by FMLE like this example was from streaming.

Africa?s Image and U.S. Perceptions in the 21st Century and Conclusion - YouTube

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?

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.

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.

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.
