Glenn asked about PAL version.
So can I get double confirmation that it really has 24p? -
Just to add some numbers, Kodak EXR 50D (5245/7245) has also MTF of nearly 200 lp/mm!
There just isn’t very many cine lenses that can resolve that. -
Chris,
maybe you could try to learn what Circle of Confusion (CoC) means. -
[Graeme Nattress] “Where I see the difference between a fixed to the camera lens and a removable “broadcast” stlye lens is in “feel”.”
Eng-lenses are also not so much highly rated in movie making. That’s why there’s so many “cine versions” of these lenses. Most of eng-lenses have focus from 5 meters to infinity within one centimeter in barrel, which makes them quite impossible to focus sharply by the focus puller.

I’m still not very convinced about the reliability of this dv-backupping, but how about dv-deck with big casettes and 3-hour dvcam-casette which is 4.5 hours in sp-mode which makes 25 GB per tape with 1:1 error correction?

[Graeme Nattress] “This is just one way Panasonic is keeping quality up and price down.”
This was already discussed months ago and I didn’t get any real and logical answers to why non-changeable would be so much cheaper. It’s the glass that covers the most of expenses.
How jvc can offer fujinon so cheaply with its 100 model?Last time the only reason that came up was, that with non-changeable Panny can control the PQ better.
And that’s very scary reason. If panny is so scared about their fame and that goes beyond what customers really want, there’s not too much future here…But I don’t understand why panny would not offer next model (hvx-300?) with changeable lens, if that’s what the customers want. There’s lot of cameramen discussing here that wants changeable lens. Why deny what they want? Why act like sony (“we know better what you need and you need interlaced…”)?
If Panny has made a market survey that tells that there’s no market for a camera that is a little bit more expensive than hvx-200 and has changeable lens, Jan, why don’t you just tell us that?
And if that survey is still undone, why don’t you go and make it.If working kit with hvx-200 would be around $10k and with hvx-300 $11-12k and with varicam $100k, the last one really does not compete with the first one. But the second one would be very attractive compared to the first one.
And btw, it’s really no use to compare still camera lens with ones designed for moving pictures.
Use is so different. You never use focus puller with still camera. You don’t have to get pans and track shots stay focus all the time with moving objects with still camera. -
[Barry Green] “There is never a savings on duplicate fields/frames when you’re working with a frame-based compression system.”
Maybe the term “field-based compression” would be more accurate.
And original question was not about better PQ with duplicating fields, but saving CPU power… -
[Barry Green] “Sort of like AA/BB/BC/CC/DD. Since the recording format is interlaced, the frames get split into fields for recording (same as in HDCAM 24PsF). The “fifth frame” is made from one “field” of one frame and one “field” of the other. Not a duplicate of anything else.”
Well, because tape systems care only about fields (they are not recording frames, just fields one after another), there are duplicate fields.
I really don’t have a clue if those duplicate fields are compressed again… -
[Graeme Nattress] “1) you need a RAID of drives for the data rate of DVCProHD.”
If we are talking about hard drives every new 2.5″ or 3.5″ hdd can handle even the fastest dvcprohd.
100Mbps is only 12.5MBps. No need for raids anymore. And in very near future even cf cards will handle 12.5Mbps. -
[Vaughan Wood] “wonder when it’s shipping!”
I feel that by the time when you are dumping hvx-200 for the next model… 😉
