MiniDVCAM tape casette is physically identical to miniDV.

I originally took this deck for an example, when this phrase “miniDV can’t handle more than 25Mbps”
was took as a somekind of law of nature in these boards.
DSR-85 was bulky, expensive and had 14 heads, but it was done five years ago.
This clearly shows that it would have been easy to develop miniDV mechanism from 25Mbps to at least 40Mbps,
what 720p24 needs.
In five years CPU speeds, hdd sizes, data tape storage sizes and everything else has grown at least 400%.
MiniDV tech has been frozen for a decade, mainly because AV manufacturers have consentrated themselves
to make same old stuff cheaper with still the same just acceptable quality.

Well, if there’s a production that combines “scripted”+”budget”+”15mins a day” I’d suggest using film.
Cheaper (if s16) and better quality.

And we are living in digital age:
every copy is a Master.
You can copy your p2’s to tape, optical disk or hard disk.

If you are worried about your shelf space with your tapes, dvcproHD tape is 35GB.
You can put 10 of those tapes to one hdd and save a lot of space.
As a backup, you could use 50GB blu-ray disks and save space also with them, when you don’t have to
keep all half empty tapes.
And all your archive is “near on-line” = instantly editable.

8 minits limit is _very_ limiting. I’d say p2 cards will be widely usable when we have 32GB cards.
Nevermind the price of cards, by the time we’ll have cf card adapters…

I guess that this mandatory pull-down with 1080 is just some weird legacy codec limitations.
If it would be for outputting 1080 via fw to some legacy tape deck, the pull-down could be done
at the output and there would be no reason for saving this pull-downed material to p2.

For editing 720p24 with FCP the bitrate has always been 40Mbps. Varicam duped frames have been
dropped off since FCP got dvcproHD codec.

“Who use hvx200”
Not so many people… 😉

P2 is a bit big for PDAs, but CF cards might be nice.
Anybody wanna bet that we will get next year HD camcorders with
CF slots?

Faster = 4x speed = 100Mbps.
If you use Sony’s editstation with it you can read tapes 4x speed through QSDI.
If you have two of those decks, you can DUB tapes with 4x speed, so then it’s
reading _and_ writing 4x speed through QSDI.

Ccd sensivity developes slowly as material science and research develops,
but I don’t see any reason why Panny would have somekind of surprising
miracle in their backpocket in case of sensivity.
AFAIK they don’t manufacture ccd’s by themself. Am I right?
If so, Panny just have to follow the overall development.

So if there is any reason to believe that hvx-200 will have exceptionally
better sensivity (which has a straight relation to pixel area size) than
other products around, just let me know.

I think we need at least 2 stops more than fx1/z1 which has 960×1080 cells.
Ccd sensivity usually gets better something like 1/4 stop per year.
If hvx will have 1280×720 it will be only 1/8+1/4 (pix size + 1 year development)
stops better. Better ad-converters and signal prosessing can help a bit, but so
far it looks like only half a stop more sensivity when 2 stops would be needed.

960×720 would give half a stop compared to 960×1080.

Jvc hd100 has 1280×720 if I remember correctly.
Any reports on its sesivity yet?

For many years there has been dvcam deck that can read/write with 100Mbps.
Although it has 14 heads, there is no limit in miniDV enclosure for not to do this.
