Here are specs from B&H. It definitely has an ac supply, but there’s no mention of a battery. And I agree with Joel you could use a properly sized battery with it.

Bulbs 210 10 mm LEDs
Output 200W equivalent
Color Temperature 6,500K
Lux 2200 at 39″ (1 m)
Dimmer 15-100%
Mount 1/4″-20 tap
Power 12 VDC input
Draws 1.25 amps at full power
(an AC to DC power adapter comes included. The DC end plugs into the panel and on the AC end is a standard AC wall plug.)
Dimensions 12 x 11 x 1.375″ (30.5 x 28 x 3.5 cm)
Stand: 74″ (1.9 m)

CoreMelt had a sky replace effect for FCP7. It seems based on a luma key. It doesn’t allow you to put your own background in, but gives you control over a number of parameters. Here’s a COW tutorial about it.COW tutorial

I agree HQ is overkill. I think ProRes422 or even ProResLT would work fine. But, select a challenging scene and encode it with each flavor of ProRes and choose what looks best.

Granted you do need lenses, etc. with the BMPCC, but you’ll obtain beautiful 10-bit imagery. And the new firmware lets you choose which flavor of ProRes you want: ProResHQ, ProRes 422, ProResLT or ProRes Proxy, so you can fit more on your memory card. ProRes which is 10-bit (no halos in sky or across graded backgrounds) and gives you beautiful video. And, of course, you can record RAW. You have tremendous flexibility. But ProRes works great. I recently shot a series of interior interviews where we occasionally had windows in the backgrounds. The camera’s latitude was amazing (we were shooting ProRes422) and we were able to hold exposure through the windows. And you may still be able to buy a BMPCC for $495. That’s a deal.

I use CoreMelt’s SliceX which lets you mask, track the mask, adjust keyframes, and color correct. As for corrections in the middle of continuous shots, I cut the clip halfway through the change, adjust each side the way I want, then apply a long dissolve to transition between the two.

It takes longer because the file is encoded at a much higher data rate and so you get a much bigger file. YT recommends using a data rate of 30mbps which makes big files and consequently longer upload times.

I agree with Eric. Why not record sound on the C300. It’s excellent. Never a chance of slippage and you’ll save time in post, too.
