HDV greenscreen for SD project
I’ve got a PSA coming up that we are shooting greenscreen. Background is an already built SD animation. Delivery is for broadcast SD. I am planning on shooting the greenscreen footage in HDV (Sony HVR-S270U). Ingest either Firewire or Matrox MX02 (If I bring the footage in via SDI). Editing in FCP, key with Veescope.
A couple of questions…
1) Would it be better to shoot it interlaced or 30p?
2) If interlaced, will I have field issues?
3) Would I achieve better results by importing the HDV footage out of the camera via SDI thru the Matrox as Pro Res or am I not gaining anything by bringing already compressed HDV footage and converting it to ProRes?
Thanks in advance for any info.

Upon re-reading my initial post I realize the last psrt of it was confusing. For the record, I am going to record HDV to videotape and import that into FCP. Would I gain anything by playing the recorded tape from my camera and capturing it via SDI as ProRes vs. importing from tape via Firewire? Either way am I just capturing the same compressed HDV signal?

[Derek Fremd] “1) Would it be better to shoot it interlaced or 30p?
“All effects work benefits greatly from shooting as progressive frames — it not only makes keying easier, with crisper edges, but the overall resolution will also be two times greater, simply because twice as much information is on-screen at any given moment.

No, it just will be a bit more difficult to pull a perfect key.

Is it possible to have your computer connected on your shoot? You’ll achieve the best quality if you can run the camera’s HD-SDI out into the MX02 and capture live into the computer as Prores 422.

I will have to test that option. I am planning on bringing my computer to the shoot to test the key setup before shooting but I was under the impression that I could not use the SDI out of camera into the MXO2 into MacBook as a capture workflow. If that is possible that would be the best solution.

[Dave LaRonde] “Yeah, kind of, but it’s still going to SD, which means it’ll be interlaced, and unless that Sony HVR-S270U can shoot 720p 59.94, the video will be interlaced to begin with. So I don’t know if it will make a very big difference.”
True.
