Two hours is normal for some compositions. It all depends on what is going on in the comp. I sent one off to render last week that took about seven minutes a frame and that is about what I expected.
It's always going to be slower to render a highly compressed format like MP4 using the Adobe Media Encoder than it is to render to a frame based format like a tiff sequence or the lossless presets in the Render Cue.
Without details it's hard to say if there is some problem other than the slowdown required to resize the video.
Thanks , I see.
