Make sure your sequence settings match the format in which you import your footage. Otherwise it won’t run in real time.

Really nice green screen material can be found at eefx.com.
Wrinkles smooth out quickly and the surface illuminates evenly.

If you can’t get P2 Genie and need something with similar capabilities right away, Imagine Products just made HD Log available as a demo, and the demo version will allow unlimited offloading of P2 cards and the P2 Store.
HD Log’s demo mode has offload features roughly similar to those of P2 Genie.

[Bob Cole] “Dean, how quiet is that Honda generator? Quiet enough to run during a dialog shoot, say 100′ away?
— Bob C”
Bob…
I hadn’t used one but I’ve seen them running. One was outside a CompUSA powering a hot dog stand and I was amazed at how quiet it was.
They’re rated at less than 60 dB, which puts them on-par with the noise level in my editing bay with a Panasonic air conditioner running about 5 feet away.
Place it around a corner or behind a car and I’d be confident it would be unnoticable, especially if you’re using directional mics or close-miking the subject.

An adapter has recently been annouced to read/write to P2 cards via the MacBook Pro’s Express 34 slot:
https://www.duel-systemsadapters.com/?productid=DP-0001
Special pricing at $99.
In my workflow, the original MXF files are stored on a Level-1 RAID. This “mirrored” RAID will help ensure that data doesn’t get lost in case a drive goes down. Cost of storage is around 80 to 90 cents per minute which isn’t cheap. But it’s still much more cost-effective when compared to the option of Varicam tape.

The Rev drives are expensive.
For my own working RAID and archives I’ve been using Hitachi drives in a Firmtek hot-swap system. I’ve been using a Firmtek host adapter for three years and started using the hot-swap Firmtek enclosure for two years.
So far no failures, and I have 15 of these on my shelf.
They’re not for gorillas. Because they’re just bare drives in sleds they do need to be handled and stored with reasonable care.
Cost is very reasonable. I just bought four 500-GB drives and sleds from Other World Computing for $793, including shipping. They’re being set up as two mirrored RAIDs.

My background in electrical work comes from a 10th-grade electronics class.
Watts = amps x volts
Each device will have info on what it draws in volts and amps. Multiply volts and amps to get watts for each device. Add up all the watts and you’ll have the total amount of power needed. From there you can get a final figure on total amps needed at a given voltage.
Just adding the amperage won’t work if each device has a different operating voltage. 10 amps at 10 volts is the same power as 1 amp at 100 volts: 100 watts. So always get the wattage each device requires first, then add up the watts.
Watts becomes a common denominator. That’s how I do it. A professional might do it differently.
Another thing to keep in mind is that many devices will have a peak draw on startup. When you’re power supply is close to the limit, be careful to avoid overloading it by starting things up in a sequence. Don’t fire up everything simultaneously.
A good example of this is that scene in “Apollo 13” where they test various startup sequences in a simulator in order to find out how they can power up the command module without exceeding a certain number of amps.

Last year I was in the initial planning phases of a remote shoot and here’s what I came up with in terms of power requirements:
Portable production power requirements
MacBook Pro: 85 watts
Seritek 1SE2 enclosure: 48.5 watts
Dolgin battery charger: 25.2 watts
Panasonic battery charger: 24 watts
MyPower MP3400: 60.04 wattsTotal: 242.74 watts
(110VAC at 2.21A)
(12VDC at 20.22A)6-hour charge = 122 Amp-hours
Honda E1000i
120VAC 7.5A.
29 pounds
0.6 gallons = 3.8 hrs at rated load, 0.157 GPHAt 2.21A load probably get 6 -7 hours run time.
About 0.6 gallons/day to charge batteries & run laptop.
1 week = 4.2 gallons. 25.2 pounds.Dean Sensui — Imagination Media Hawaii

Solar power has a drawback in that you need sunlight to charge anything and if you’re using the equipment during the day, that’s a problem. Unless you have two sets of batteries: One set charging while the other is being used.
Another option is a small generator like the Honda EU1000.
https://www.hondapowerequipment.com/ModelDetail.asp?ModelName=eu1000i
It’s quiet, fairly lightweight (30 pounds) and doesn’t use a lot of gas (just over a half gallon for more than 3.5 hours). And generates enough power to cover your needs. You might want to bring a long a small UPS to ensure smooth power delivery.
If you’re bringing a laptop then maybe invest in P2 cards, one or two P2 Stores and forget the Firestore. That would be one less battery system to deal with, and a single HVX-200 battery will easily run the P2 Store all day long.
