You already know the site and the code, this help me a lot to explain what I need.

1) A listbox "Format", which options are fixed to "MOV" or "MP4", the prices are fixed (see point 2).

2) Add a listbox "Resolution" in the product page to choose a resolution, when changing the resolution the price will change automatically, this are fixed prices:

MP4 640x360 - 360p = $2
MP4 854x480 - 480p = $3
MP4 1280x720 - HD 720p = $4
MP4 1920x1080 - Full HD 1080p = $5

MOV 640x360 - 360p = $4
MOV 854x480 - 480p = $6
MOV 1280x720 - HD 720p = $8
MOV 1920x1080 - Full HD 1080p = $10

3) The admin must be able to add different amount of scenes for each video, set the amount of text lines, characters, and choose the price for each version (in porcentages), the client can choose the amount of scenes from a listbox on each product page and the price will automatically change (and the textboxes and max. amount of characters will change too).

4) The admin must be able to set different color presets (some videos doesn't need this feature), this means another listbox in the product page to choose the primary color, it just add a "_COLOR" to the SKU, price doesn't change.

5) The SKU (product code) should change depending on the options selected from the listboxes (not the SKU in the product, just in the cart and the email sent to the server). For example:

14_720_5scenes_BLUE

This code means the SKU for this video is 14, the resolution is 720p, the amount of scenes is 5 and the color is BLUE, my system will automatically detect this SKU's and proceed to render the video with this specs.

Take in mind the system sends an email to the server with the SKU, username, email and text for the video. I forgot to mention the format adds the format to the SKU too:

14_MP4_720_5scenes_BLUE

This code means the SKU for this video is 14, the format is MP4, the resolution is 720p, the amount of scenes is 5 and the color is BLUE, my system will automatically detect this SKU's and proceed to render the video with this specs.
