Either link me to right thread about this or let me know.

Are there different workflow for live greenscreen with HD-SDI output from Canon XL H1 1080/30F or JVC HD250 720/60p or 30p? I considering get Anycast Station HD for live-chroma keying purpose. (Want to avoid post work in greenscreen as much as possible because of space and time).

What are potential pro and con for each?

Thank you
Joseph
