Coder for a simple online video handler creation
 

Hello.

I need a page for my website where I can do following:

1. Specify one/several source video file(s) or directory! on the web server.
2. Choose watermark that will be placed on the source video(s).
3. Select the video file that will be joined with the source video(s) at the beginning.
4. Select the video file that will be joined with the source video(s) at the end.
5. Specify directory on the web server where result(s) will be saved.
6. Start button.

Fade effect transision lasting for 2.5 seconds should be added to the join places.
Specifications of the result video(s) should not differ from the source(s) (bitrate and resolution).
Processed source(s) should be moved to another directory of the web server.
