I'm going to post side by side screen caps of what I'm describing, just can't at the moment and figured I'd at least get the question out there.
I'm having some issues with my video going from CS6 to Vimeo. The exported video file (which is h.264 mp4 as vimeo suggests) when I play it from my computer retains its crispness and colors pretty well, even compressed down to 200mb. However when I play it over vimeo it looks highly degraded, edges are much softer, there seems to be some mudding or aliasing that isn't there in the source file. Obviously vimeo encodes the video to a smaller bit rate. However I've definitely seen videos on vimeo as simple as test shots that look better then this, so I know it can handle better quality.
What would I be doing wrong perhaps? I understand thats a possibly vague question, so let me know whatever Info you'd need to better help diagnose my problem, because this seems to keep happening everytime I upload something.
