I need a encoder who does this job:
Ive a database of user, every user has a random ID number of 10 numbers, when the user add one video to his account your script/encoder take the source file/s of the video from my server and encode it in a new unique video (I know, it will take time, no problems about) with 2 watermarks:
1 - static watermark in the left down side of the video, this is easy
2 - a dynamic watermark (I generate a image with transparent background for this). This watermark move in different position every N second (from 10 to 30, random) using a slow *cross dissolve effect* for don't disturb the user who looks the video. I will give you the list of pixel coordinates where the watermark can be located (random as well). The watermark change location in random way for all the duration of the video.
Thats it, easy.
