What is the best course of action?

I am creating a presentation that has video and I am synching flash objects with it.

There is no audio synch.

What is the best file type to import into flash. I need the video to have an alpha so that I can put objects behind and in front of it.

I'm fairly new to complex video in Flash, please be specific.

Thanks

If you need an alpha channel in video, your only real option is to use Flash 8, and encode your video into FLV format using the On2 encoder...
