vidding with multiple sources?

[electrizity.livejournal.com]

Hello! I have an idea for a vid I want to make centered on a musician, using footage of interviews, performances, and music videos. I now realize that I have more than ten sources from which I want to edit clips, and each of these sources is in a different format, with different aspect ratios, frames per second, etc.

Clip 1:
H.264, 1280 × 720, 0.008999999999999999 fps, 1.80 Mbps

Clip 2:
H.264, 640 × 320, 0.003 fps, 600 kbps

Clip 3:
224 MPEG-2, 1920 × 1080, 16:9, 29.97 fps, 65.00 Mbps, upper field first

Clip 4:
224 MPEG-2, 720 × 576, 16:9, 29.97 fps, 9.00 Mbps, progressive

Clip 5:
224 MPEG-2, 720 × 480, 4:3, 29.97 fps, 9.50 Mbps, lower field first

And so on and so forth.

Is this venture doomed from the start? I know it's been done before, but I'm also still a relative n00b. Does anyone have any advice or know of any guides for this sort of project using Final Cut Pro? Thanks!
