The upgrade (just released) adds a new category 'HD recording' to the 'HDD Mode' screen.

Only tried it briefly but all seems to work fine. I recorded a few minutes from the Z1 to the FS4 then played it back through the Z1, also checked the m2t file when transferred to computer.

The revised manual on the CD (pdf format) simply says

"Support for cutting edge HDV camcorders with 720p and 1080i capacity equipped with a Firewire 1394 connection"

What it DOES mean is that the continuous recording limit of one hour (set by the physical size of HDV recording tape) is extended to almost three hours - of particular interest to event videographers.

Have Firestore sorted out the battery life now then? or is that still a potential pitfall with long recording times?

Focus now do a longer-life battery (supposedly three hours) but because of it's extra size it won't fit in the holster that Focus supply.

Since the holster (with Hama shoe adaptor) provides hot-shoe fixing on all types of camera (see pic as example) and I value this above battery life, I've not bought a long-life battery.

That looks suspiciously like the IDX LED light sitting next to it, which I believe to be 12 volt. If you have 12 volts that close to the base of the Firestore, what's to stop you splitting a feed off into the bottom of the FS4, and waving goodbye to all FS4 powering issues?

Or do IDX do a 6 volt version of the LED light........ ?

The IDX light is certainly 12v and runs off a small sealed lead-acid unit.

Very soon after I got the FS-4 I tried to run it on 12v (from a different but fully charged L-A) and it didn't want to know. Although the internal FS-4 battery is 11.1v the external dc socket is labelled 15v so maybe 12v is not quite enough to get though the dc regulator.

12V on Firestore is OK

I made up a 12V Battery pack with a Petrol bag, a 12v 7ah SLA battery, a small enclosure to put a Voltage meter, a couple of terminals to plug in accessories, and two cigarette lighter sockets. I use this to power my Firestore FS4ProHD 80Gb - last night having tested it recording for 6 hours straight off the battery pack. 12V runs fine for these units, but what you will find is that once the Unit is off the 12v Supply your on-board battery may not be very charged, 12v will charge the battery over a long period - but only if the unit is not in use.

It's not unusual for power supplies to need around 4 volts overhead to work properly. The best I've ever designed worked down to 0.8v overhead, but that involved some unconventional circuit design, and, after 25 years, I've forgotten how we did it.

Get my test cards document, and cards for 625, 525, 720 and 1080. Thanks to Gavin Gration for hosting them.
