What i dont understand is why you dont just shoot the damn thing on Digi Beta.
The cost of a one day shoot including camera man is roughly $1000.
Then all you have to do is connect the camera straight into your decklink cabels.
If you dont have decklink or if the client does not have $1000 then perhaps DV is worth it but remember that there will be lots of exra time spent on getting the key looking decent when shooting on DV and it will always look a lots worse anyway.
Therefore I refuse to shoot green screen on DV. If the client cant pay for the Digi Beta camera then I dont wanna do the job anyway. Just my 2 cents.
