I'm in the process of designing a website, and I want to use Flash as well as
Quicktime. The site deals with stock footage, so the beauty of Quicktime is
that the user can simply move through the video frame by frame and choose
exactly the shot he or she wants. But when it comes to Flash, is there a player
available that will allow the user to move through the clip frame by frame?

If I am understanding you correctly, you want to be able to navigate through
the quicktime movie, frame by frame.

The setting is when you import the .mov file. Choose embed in the timeline
instead of the other options. Once complete, you can move the slider across the
timeline and view your movie frame by frame.
