Judging from what you're asking, I'm going to say there are problems that can occur while doing this. First off, the video is synced to the finite length of the music... therefore, any editing to the "visual" portion of the video (adding photos) may or may not end up matching the audio length once you're done. It becomes a very tedious task to match the music length to your new video simply because there is no way other than trial an error to guarantee you're removing enough video to replace with photos. Does this make sense?
What would be a better choice is to create a slideshow that includes many photos of your team and then have the song Rock Star play in the background while the photos get displayed. After creation, burn the slideshow to a CD that can played on the computer. Does this sound like a feasible idea?
I'm asking the questions because to do what you originally want to do will require a lot of work. Its not as easy as you would want it to be! Actually, either case will require work and a learning curve, but a slideshow would be easier and PTE (Pictures to EXE) can do this effectively. The catch is that PTE will cost you $75 for the Deluxe version which you really should opt to purchase in lieu of the Standard version. A plus, is that it's a lifetime purchase, so any updates to the program comes to you free. PTE has been around for a while, and is very popular, so a lifetime purchase isn't so bad. (I started with version 3.0 and now it's at 5.5)
I've created quite a few slideshows for family and friends using photos and music files for the background. The slideshows can be played on any computer, and with PTE, you can even burn to DVD to be played on a TV. Admittantly, I've never gone so far as to create for TV as I never took the time.
In any case, PTE also has a help forum if you might be interested in it. Highly recommended!
