I used the same setup for a music video last month. I used the 'Vivid' scene file
available from Panasonic and made only a few adjustments. I rated the camera at 200 ASA using this setup, and was able to use a studio 2k as my key light for the entire band... so it's pretty effective in relatively low light (25fc was key level). I shot it at a T2, so I could have probably even used the Zeiss standard speeds instead of the superspeeds. If it's in your budget, I also recommend getting the paintbox. Hope that helps.
