I Need a Video Converter

I am working with the 5th and 6th graders at church. They came up with a really cool video idea and the head of the Sunday School department called me. She said nobody in the Sunday School department had the technical expertise to help the kids, could I? I said yes, and I do have the knowledge to help them, but I am short a couple of tools.

I have already found a couple of video cameras (multi-angle shots) and camera operators lined up. I have the kids busy designing their storyboard and deciding on locations, stars, etc. The kids have to do all of the coordinating. This is their video. Their teacher is available for support and guidance. I am running/teaching the tech (and occasionally providing support and guidance for their teacher who knows she’s over her head).

What I still need is a good video converter. The scenes are going to have to be edited and spliced. I know how to do it but I am far from an expert.

One of the 6th grader’s parents said she had a video converter for Mac, but I’d have to use it at her house because it came bundled on their Mac desktop.  I don’t want to be stuck in their house at the mercy of their schedule and they likely don’t want me underfoot all the time, either. I need a program — it can be Mac or PC, but with Mac software I could get Amoeba’s help — that is easy enough for me to use and teach 11 and 12 year-olds, but will still produce a quality video. Anybody have any experience or products they recommend?
