Here is my situation:
As a project at work, I have had to encode all 160 hours of our three IT-training classes into quicktime format. These video files are not actual live video; but rather a series of powerpoint slides along with screen-recorded demonstrations on a computer screen, all accompanied by voice lecture.
I was able to convert these classes into quicktime video format, with very high-quality and adequate compression using H.264 with no problem. So I have all the master video files on my hard drive now.
PROBLEM:
Copy-protection. We want to be able to distribute the video files in quicktime format on a DVD+R but need to be able to control each copy with a serial number. The solution we came up with was to watermark a nearly-transparent serial number over all the video files, unique to every copy. That way, for each copy we sell, we record the serial number sold to the purchaser, and then if a copy of the video ever shows up online (which is already happening with our older classes) we can trace the purchaser through serial number to take legal action against them.
Re-encoding all 160 hours of video EACH TIME to create a new watermark is extremely tedious. Even with a blazing fast brand-new iMac, and three Mac Mini's all clustered together using Apple Final Cut Compressor, the process still takes nearly 5 days to make one, watermarked set of videos.
Does anyone know of a better way to do this? Perhaps either more efficient, or a completely new solution altogether that will still allow us to uniquely track every copy? We anticipate needing 300 - 500 copies made in total.
