Alright, so recently I found a Laptop under my bed that hasn't been used in a long while the specs aren't brilliant 3GB ram at the most, I thought it was a good idea to render a few videos on as it's portable I know it might be super slow but that wasn't the issue. Anyway when I rendered out a video and it finished it looked absolutely fine however when I uploaded it to youtube when lots of action appeared on screen it would begin to pixelate. I rendered the same video on my gaming PC 16GB Ram, i7 4790k 4.0GHz and the video was FINE after render and FINE on YouTube any solutions to why this may be?
