Dan,
As regards the DVPRO25/50 upconvert from the 1200A, it actually is in the manual; but it only comes out the HD-SDI spigot, not the firewire, so a work around is to use two 1200A’s one to play back and upconvert and the second to record. Then play the recording into FCP through the firewire. It is labor and machine intensive, but possible!

Chris,
I’d like to hear such a report as well, but I don’t think the “F” will be obsceleted until the D5 Varicam arrives. Of course it seems like the whole landscape is in flux with the announcement of the Thomson/GV Infinity at IBC. This system, which records (or rather “stores”) on non-propriatory Iomega REV and compact flash media would seem to render the P2 Varicam dead on arrival, although the issue of 24/25p remains, and whether JPEG2000 proves to be acceptable for camera origination, especially at the $20K price point and 45 minutes of HD media at $60 list.

Mac,
Stepdown transformers are bulky and inefficient for lighting; you’re best off just buying 220v globes if they’re available for the units you own/use. Otherwise an elegent solution I’ve used is to wire up pigtails to use two 120v units in series. This solution is almost weightless, almost free and further solves the local connector adaptation. I’ll make up the US household part before I travel and go to a local hardware store any buy the plug in connector when I arrive. Several minutes later I’m on the air. As long as you are using any even number of units your fine, otherwise use a dummy 120v load for the odd units.

David,
Lighting for HDV would be the same as lighting for any 1/3″ camera. You are correct in your plan to minimize the ambient light to create a moody environment, but you can achieve the wide open apperture with ND filters as well. This might be the case if you used a northern window as the source; remember that Rembrandt did’t have the luxury of artificial photographic lighting instruments!

Bob,
Don’t feel bad, I haven’t heard back from Dennis yet either!

Craig,
The manufacturers make so many items (just look at the Mole or the Chimera catalog) that they cannot afford to write instructions for every unit (although Chimera often does provide some paperwork because assembling some of their units – especiallly the “pancake” and “lantern” units) can be mind boggeling! This is why they put so much effort into the catalogs and why they are such a great resource.
Otherwise they count on their dealers to provide the cursory explainations that neophites might require as part of the sales “pitch” to encourage you to buy one unit over another (cheaper) one! With this in mind beware of such pitches as the folks in the stores rarely have the requisite lighting experience to provide much help, other than at specialty lighting shops like Studio Depot or Barbizon.

Craig,
You’re asking all the right questions, and seeking out the information on your own in catalogues, etc. so it’s clear that you’re on the right path to lighting success!
It sounds like you’re missing the Chimeras’ “speed-ring” which is used to attach the softbank to the light (in which case you do not use the barndoors). To visualize what I’m talking about check out the chimera.com website and find the proper speedring for you light, then order it up from B&H or whomever you use for lighting supplies.
One light it often enough, it depends on the quality of light and mood you’re trying to create. If the Chimera-equipt light is from the front (near the camera) it’s described as “flat” and most times no fill is needed. If I were to use another light in this scenario it would either be a backlight to create seperation or a light on the background to indicate where the subject is.
As the Chimera’d key light is moved more to the side, you’ll notice that the off-side of the face is more in shaddow. This is often dramatic and more realistic, as if the light is coming from a window or other source to the side. The thing to watch for is to maybe keep the light in both the subjects’ eyes, and for pleasing shaddows from the nose. Here the height of the light often comes into play. Some photographers make a point of creating a triangle of illumination on the check to the off-light side (aka Rembrant lighting), while others prefer to fill the shaddow with a bounce card or even another light in a card or off a wall or ceiling (note the color of the bounce object).
As far as monitoring the effect, without a monitor, you are limited to using your eye and the b&w viefinder (which is a good tool to judge the contrast and exposure), what you’re really missing is a way to judge the color effect. This can be important when mixing daylight and tungsten (the color of your supplementary lighting). With time and experience you’ll find that you mught want to add some blue color correction gel when mixing light in this manner (CTO 1/4, 1/2 or full), but you’ll also find that doing so further limits (as does the Chimera) the amount of light emerging from your 650’s.
That’s why lights are offered in larger wattage and also in daylight color balance (HMI and 5600K tubes for Kino Flos).
I hope this helps. Now you’ve got to experiment with your new tools and find out what you like and what works for you. Remember that the rules are merely guidance, and “proper” lighting often required more tools and power than you might have at hand, so the challange is often to do the best you can with the resources you have!!!

Bob,
I guess it all depends on how hefty your boom stands are!
I use my 4′ Fourbank Kinos on a Mathews Baby Boom Armn and Combi stand all the time. I ballast the whole affair with a sandbag on the stand and on the arm itself.
I suspect that the Mole Biax 8 would be a little too heavy for this rig, but could be flown other ways; perhaps with a more heavy duty “mennace arm” rig which Hollywood grips often make with speedrail or 2×4 lumber, rolling grip stands, ratchet straps, mounting hardware and sandbags. If you are in a “production” environment with all this gear at the quick, go for it, other wise consider the KF Baby Boom option.
Mole makes a “Comet” boom which might accomodate the weight, but it iself is a beast to transport and setup; I’ve seen these things “fly” when unballasted by removing the light on the end. Any of these solutions require care, skill and often two people’s undivided attention; remember you’re usually using a boom to dangle a heavy light above some unsuspecting persons’ head!

Craig,
You’ll learn to love your Mole kit over time due to it’s functionality, compactness and versatility. Unfortuneately there is no instruction book per se, but let me try to help you out with the various queries you have.
Of course regaular grounded outlets are ok, in fact they are preferred, the ground connection protects you from possible shock in the case of a short in the light caused by damage or misuse. It is still possible to use the light in a two-pronged socket with a “three-to-two” ground plug adapter which you can procure at yo9ur local hardware store.
The safety screen is intended to protect against the unlikely occurance of a globe explodeing and showering shards of glass on your subject. Although this rarely happens, I have been present when it did, and without some barrier between the light and the subject it can be quite unsetteling! In addition to the safety screen, a scrim or other diffussion will also serve as protection.
The globes don’t care if you turn them off and on between takes, and doing so, especially in hot environs is a good idea to keep the set cool.
A “naked” open faced quartz light, like these tweenies (and their cousins the mickey and mighty) by themselves do create a rather “gross” quality of light. The creative lighting technician usually modifies their output (especially for portraiture) by diffussing or even bouncing them into white cards or other types of reflectors. Diffussion can be as simple as attaching something like Lee 216 to the doors with wooden clothes pins, unfurling a roll of diffussion in front of the light or by using a Chimera or other light box. All these solutions turn the otherwise raw light created by an open face into a punchy soft source.
The Chimera option is particularlly elegent because it eliminates the use of additional stands and offers options of controlling the spill with grids and honeycombs. In addition in their “closed-up” modes the Chimera packs neatly inside the kit box. An “X-Small” or “Small” sized Video_pro would be appropriate (or even one of each for use as key and fill).
Unferling a roll of diffussion (like the 216 or even 1000H traceing paper) in front, by using a c-stand, creates an even larger source, which has its’ advantages, but then requires even more c-stands, sandbags and large solid flags to control the spill. This method becomes more eq2uipment and labor intensive, as well as often requiring a larger “footprint” in the scene, so is usually reserved for production of commercials and such. One variation of this technique is known as the “book-light” effect, where you bounce the light into a reflector and then through the unferled diffussion. This creates a double-diffussed and very soft source, but ususlly requires a source twice as big (or more) like a 2k of 5k, but you could use two of your tweenies and see if you like the effect.
As you should now realize there are many methods to use and control your open faced lights, that’s why they are so popular for folks who need a compact and inexpensive light kit.
Good luck!
