[toke lahti] “Sounds like 1280×720 ccd’s with pixel shift in both axis.
If so, that’s really great, bigger pixels than Z1 or XLH1!”As they say, there is no free lunch,
Bigger pixels will mean higher sensativity but less native resolution (for a given imager size)Mike Brennan

“If you got something to offer say it here on the Cow.
Be direct, don’t be bashful or shy.
Now speak up I can’t hear you cause my Googlevision TV volume is up too loud.”Huh?
Don’t have a clue what you are talking about …! I’m hardly shy about pointing out faults with a f900 if I run a webite listing them!Getting back to the subject the concept Ty is wondering why the f900 is noisy as it is.
This is due to it being the first 12bit HD camera that was designed in a hurry.
Up until the 400 from Panasonic there have been no other 12bit HD camcorders.
Varicam engineer said they couldn’t make Varicam 12bit due to heat and wanting to keep camera small.
Sony made it and solved the heat with noisey fans.In respect to comments about noisey cameras in general compromises and workarounds are made everyday.
I used the 790 camera in same room in a pro studio about 6 feet away whilst Sting was recording the actual take of a number. I put a jacket over the camera.
Ditto Shinead O’Conner. A f900 would also have required a barney for the take.Like SD cameras some are noisier than others, usually as they get older or if they haven’t been serviced.
A comment that soundrecordists could make to PMs before a music recording shoot. Sony 20 and 24 inch monitors have a fan on the HDSDI input which is often overlooked.The fan can be switched off but will eventually come on when the camera heats up.
It could be better but it doesn’t seem to be show stopper, many soundrecordists I know take a roll of fabric or drape if they have critical sound to record on location on HD.
Using the Panasonic 400 tomorrow, will be interesting to see what a few years development does to reducing heat.

Thanks Steve.
I’ll refer to SDX900 references rather than the Varicam film rec
Sounds straight forward.Look forward to using the combination of 12bit AD and 4:2:2!

HD XDCAM isn’t available yet.
Many are confused by the Sony roadshow that XDCAM is hd capable.Mike

If you have shot on video before then zebras will be ok.
Focus will be your big issue.
If you are thinking of buying a used 700, I know there are a few in South Africa doing wildlife, be aware that the viewfinder is probably getting soft, not what you need shooting wildlife on HD.730 has only one filter wheel which is a bit of a drawback for the sunny climates.
Best thing is to learn as you go by replaying on at least 14inch crt or 1920X1080 LCD.
Do as much testing/shooting before you go if you can’t get this kit on location.I’d value a 700a at about US$17-22k. This could drop to $12k within 18 months.

“Are you trying to imply that Ty is not a professional? It was clear to me that he is not a novice just a professional seeking information.”
No it is obvious Ty is a professional, the mystery to me is that he was surprised that/by f900s noise, despite having written the book about audio for video.
Hence asking the basic questions to check there wasn’t something basicly wrong in the room ie camera mic on , mic placement, faulty camera. Kinda things that happen to everyone eventuially.
I guess this led you to believe I was questioning his professionalism?“I regret you did not mention the audio information on your website in your first post which would have been quite helpful for all “pro’s” seeking information.”
Googling the subject “f900 noisy” would get to my site and also I notice, to this very thread!

“l qualified soundmen would place the boom mic within 18″ of the subject for a sit down interview. No such thing as a super duper telephoto mikey phone.”
On a public forum one has to eliminate even the obvious.
Sure we all know the camera is noisy! so why is the sound guy complaining about the camera!If the soundrecordist is complaining it means
1/ There is an unusual fault with the camera so it makes more noise.
2/ Soundrecordist has not worked on video before and is not familiar with normal sound from camera.
3/ Soundrecordist is a novice and either mic placement is incorrect or he has camera mic switched on camera on but doesn’t know it. (a not uncommon occurance with pros too)I said in my post “the critical piece of information is how far the boom was from talent” refering to a previous post from Ty where *camera to subject distance was mentioned*
Tony, you assume the sound op was a pro and experienced on video, this is not always the case!
You also assume that I was ignoring that HD cameras are noisy, I wasn’t, others had already mentioned video cameras are noisy in this thread. I do refer to noisy cameras on the FAQ on my website and included it in a book for European Digital Cinema Production Guide, which included a interview with Bergmans dislike of shooting HD due to noisey cameras.Ty you mention it was a Sony HD camera. Was it a Z1? FX1? f900? HDW750? HDW730? or a HDW700?
The older camera, HDW700 will almost certainly have needed tape transport parts changed or it will become even more noisy. f900 mark ones are probably also of a vintage where this should happen.Is this mentioned in your book that you advertised on your post; “Audio Bootcamp Field Guide”
was written for video people who want better audio.Mike Brennan

If the monitor is in the same room as the lights are when you turn the lights off you’ll see more grain.
Move the monitor or shroud it in black and see if it still happens.
Otherwise there is no internal circuit that should do what you descibe.
Remove cover and reseat boards
Record the shot and replay with lights on to see if it going to tape and isn’t a monitoring issue.Mike Brennan

Thanks for the comments, it is easy to get a few good frame grabs if you are shooting 25 of ’em a second for 50 minutes:)
Let me know how the grade pans out.Mike Brennan
