I have created an Illustrator mock up for an application in which users can create their own video montage. The interface has been designed, the video clips have been selected and edited, and all that's left is the coding. I do know Flash, however this seems a bit over my head. The user will need to be able to select a number, and the associated video clips will become visible. They can then preview this video clip in a preview area that will then become visible. A button is also made available for the user to add this clip to their sequence. When 5 video clips have been added, users may then add a soundtrack. When all is finished, users may view what they have created.
