I was looking for a CUDA based encoder software as i have lots of videos to convert every day and CUDA converts them in less than half the time which is fantastic. I came across a encoder with this feature called MediaCoder. I love it and i want to use it.

There is one problem. There is no way to add a logo on the video. I hear this is possible with AviSynth. As i am a complete n00b at file conversion, it would be really helpful if someone could point me towards a ready-made watermarking script that i could load directly into MediaCoder and have the watermarking done. I searched a lot on Google but could not find anything that i could understand.

Please help me out here. It would be really helpful. Thanks.
