Dear Steve,

We expect to post a major new release of the firmware, possibly as early as next week.

It is in final testing.

We suspect that most of the problems that people have reported we due to cable problems and/or a glitch in the HD-SDI signal.

We could handle, in recent releases, the loss of the HD-SDI signal, for example if one powers down the camera while recording, or unplugs the HD-SDI cable. We just close the file, and it the power or signal is restored, we start recording again automatically.

But, we could not gracefully handle very slight glitches in the HD-SDI signal.

I was testing the new release candidate yesterday and I could not make it fail. If we detect a glitch, we close the file and start recording again. But, it does take us some time to resync to the incoming HD-SDI signal and restart the recording.


Two other recently reported problems involved race cars. One involved stunt jumping a card over 100 feet.

In both cases, depending on the setup, very high quality, double and triple shielded HD-SDI cables should be used in an attempt to prevent very serious EMI (Electromagnetic Interference) from interferring with the HD-SDI signal.

Now, in recent months, we have had major productions which have used the Flash XDR without any major problems. One was in new Zealand, a 13 week dramatic series for television, and the other is Cash Cab (Discovery Canada). Another one was an episode of Mighty Ships. This was an interesting one in which they would have never gotten the shot without the Flash XDR (This is according to the crew.)

At trade shows, I get a lot of people coming up to me reporting how much they like using the Flash XDR.

The nanoFlash builds upon the field experience that we have with the Flash XDR.

Just read in the manual that it's advisable to warm the unit up for 5 minutes before use - what's the story there?

Dear Steve,

In normal weather conditions, normal ambient temperatures, this is not really necessary.

In extreme cold conditions, we recommed this to allow the unit to come up to a reasonable temperature.

While this has not proven necesary, one could easily turn on the Flash XDR when one first turns on their camera.

For example, if it is -40 outside, I would recommend placing the CompactFlash cards in the Flash XDR and then powering it up. There is an internal temperature display on the LCD. One could monitor this to ensure that a reasonable working temperature has been reached.

Some CF cards may not work below -25 degrees celsius, but the Flash XDR will warm the cards.
