Over/under crank with the Flash/Nano

[Paul Cronin]

Maybe 1080p60 is the first step toward 1080p120 for super slow motion with the Nano2.

Any update on the under/overcrank feature?

Hi Bob-
We are adding XDCAM Optical drive support and faster compact flash read/writes as well as fixing some minor bugs this month. Additonally, we hope to qualify an affordable ($300) 64 GB Compact Flash card.

Over/undercrank is on the development list for November.

Best-

Does this mean that hot swappable cards has been pushed back yet another month?

Thanks for the update Mike. Will the 64GB cards handle 220Mbps?

Shot your I-Fame clips yesterday from the machine they look nice. Will contact Dan in a few hours when off a shoot.

Dear Paul,

We are still qualifying the 64 GB cards.

We have sent out 10 of the 32 GB cards, from the same manufacturer, to obtain some real-world, field experience with this brand.

We are testing the 64 GB cards in our lab.

These are very fast, very high performance cards. Yes, they will support our 220 Mbps mode.

Dear Billy,

I had an email meltdown yesterday, while fixing my email problem; I was not able to get on the Internet.

I will check on when we will have "Hot Swapping".

For discussion purposes:

Fast, High Performance 16 GB CompactFlash cards have always been expensive, comparatively speaking to other CompactFlash cards, but not to other professional media.

SanDisk Extreme IV 16 GB cards are currently $159.95, after rebate at B&H.

Four of these cards would offer 64 GB.


Now, the 64 GB, fast, high performance cards we are testing, are much higher in performance (about twice as fast), and cost less than half of four of the SanDisk Extreme IV 16 GB cards.


We are working on Hot Swapping; we will be providing Hot Swapping, as soon as possible.

But, please consider this:

Hot Swapping is inherently dangerous as one may eject the wrong card.

Also, one must be certain to replace the swapped out card with a card that has been formatted and has space left on the card.

Note: We show on the LCD a bar graph of how much space has been used on each card, so one can easily check to ensure that a full card was not inserted.

Two 64 GB cards provide approximately two hours and 48 minutes of record time, at 100 Mbps Long-GOP without interruption.

50 Mbps Long-GOP, the same quality as the Sony PDW-700 and PDW-F800 cameras offer, will provide approximately 5 hours and 36 minutes of recording without interruption.



Personally, I feel that investing $600 in 128 GB's of extremely fast CompactFlash cards is better than taking the risk of the wrong card being ejected at an important event.

But, as I said, we are working on Hot Swapping.

I will determine our latest schedule and report back.

Hi Dan:
Is the Flash XDR capable of 1080 @ 60P capture ?

[Dan Keaton]

Dear Mark,

No, it is not.

Our HD-SDI inputs are programmed for 1.485 gigabits per second, which is the standard for single-link HD-SDI that is in common use.

Dual-Link HD-SDI is typically required for 1080p60.

There is also a 3G standard and it may be on a few very high-end cameras.

So, to get 1080p60 one typically needs a very high end camera, and dual-link or 3G support.

[Mark Job]

Hi Dan:
OK. Ironically my new Sony 9 inch HD Monitor has single Link 3G support (Sony LMD 940W) I understand 3G is a new signal chip which allows up to 3 Giga-bits per second data flow.

[Dan Keaton]

Dear Mark,

Many converters and other devices work with 1080p60.

Our transmitters and receivers in the Flash XDR and nanoFlash are also capable of physically transmitting and receiving data that fast.

However, 1080p60 is twice the amount of data as 1080p30 (which is obvious).

Your 3G Monitor, and other 3G converters/devices probably do not have to process and store that amount of data. This is where the problem comes in.

Do you have a camera in mind that you want to use to obtain 1080p60?

It has its uses. One of the old tricks is to undercrank a car chase with the cars traveling at normal highway speeds. Played back though, it will appear that the cars are traveling much faster.

complicated fight scenes are almost always undercranked. this way the actors can move with deliberate slow actions to make sure they don't kill eachother. when played back at standard speed, the action appears fast, not slow like when the actors did it.

[Greg Boston]

That's another great example of under-cranking, Aaron!

....No. I'm shooting with the Canon XL H1 exclusively for now. Perhaps I have misunderstood ? The implication here is if your particular camera cannot shoot at 60p per second, then there is no technically feasible way the XDR or Nano can be programmed to record this frame rate, and even if I did have a camera capable of true 60p, then there is no way to do it, or is there ? I was thinking of a frame or line doubler, which would turn 30 into 60 p somehow ???
