VariCam on FinalCutPro 4.5HD
Is it possible to cut uncompressed VariCam footage on fcp4.5HD? If so what is the file size per 1 minute of footage?
I am going to be overseeing post on a project where they are shooting VariCam HD. Then I want a local post facility to load the footage, uncompressed, onto my external hard drive. Then I will cut the project on a powerbook running fcp 4.5 HD. The project will be saved on the hard drive and given to the post house which will output a master to HD and make DigiBeta dubs.
The project is a one minute commercial and a three minute video. The director predicts that he will shoot 2 hours of footage. What I need to know is – can I fit the two hours uncompressed footage onto an external drive and will fcp 4.5 HD cut the project.
Thanks,

That depends what codec is being used. Are they capturing 8bit or 10-bit uncompressed to an AJA or something along those lines or capturing native DVCPROHD via Firewire?

You will not have throughput fast enough to deal with uncompressed HD. If the footage is captured via Firewire in the DVCproHD codec then it should be fine.

You need an x-raid or other fiber raid to edit uncompressed HD. A powerbook can edit 720 24p in the DVCPROHD codec from a firewire 800 drive.
Uncompressed HD is only really feasible on a G5, with duel processors.Chris Bell

I will be using the dvcpro codec. Thanks for the tips concerning uncompressed.
Does this workflow work well? I have read articles that state that once the footage is in fcphd it can be onlined and fed right out to film.

What you could do from FCP if you haven’t touched it much in there is recompress the sequence media using the media manager to a 10bit codec and project (uncompressed ideally) then output the file/s from this new sequence (will not play real time now on a laptop system) to hard drive. Take this as a quicktime or image sequence to your post house for grade and film out.

You might want to recapture the final cut at a 10-bit uncompressed resolution throuhg and AJA KONA2 or similar product. This plays back at 165MB/sec and the KONA 2 can do a realtime upconvert to 1080i with Varicam footage.
If you capture the media this way for your final transcode you will be at a full 1920x1080i file size that will be more information for your film out.
It will also be much cleaner with any renders and FX you might have.
