Make user interface for blend app in Flash / Adobe Air

This project is to make user interface in Adobe Air to get user input and call operating system command line app to process 2 video blend and export result Specifically the Adobe Air app must have user friendly interface to allow to select part of video for crop. User select two mp4 video files (1 base and one for blend). The base video must be full screen video displayed in flash video player on whole video area in the interface. User must be able to select rectangular part of base video to place the video for blend. To select blend video area user must click on left corner and then move mouse by holding the mouse button, selection ends when user release mouse button. After are selected the blend video must play in that area. User must have blend option buttons which should open selection of "blend" function parameters. User choices for blend are described here [login to view URL] Specifically need allow user to select: a) one of 25 blend mode options (like addition,and, etc). b) opacity with slider from 0 to 100% for blend video c) start and end time of blend video. Should be possible to set number of second in main setting and frame (1-24) for precision. Start and end parameter send to command line app is in frames. e) following transition effect setting separate for transition in and out: - no transition (just appear) - fade in - fade out User must be able to play preview and see both videos.. Only opacity option should work for preview.. Also allow user to start playing video from where they want with slider for video player. After click on "Export Video" button user must be able to select folder and file name for exported video and then Adobe Air app must call operating system app with proper blend parameters based on user option selection then monitor error channel for progress to be able to display progress bar. After processing finished must display success buttons Important: by default output terminates when shortest input terminates. So if base video is longer than blend video you must combine output processed video with remaining part of base video. (you can do it easily using same command line app) You will get graphics PSD with UI components design which you need to arrange. If you do good job I have many follow up projects.
