I am looking for a very program

Hello
In search of a service or program that would uniquely batch video on YouTube and put a watermark on it. I used to use a video spin blaster for this, but now I just stopped the program to perform its functions. Please tell me where to download the program for my requirements ???

Get it done on freelance sites if you don't find an existing program.

There are couple of opensource code which can do the job. You just have to modify it accordingly.
