I have been using the t3i for a while as the video quality i am getting out of it sucks. There are videos on YouTube with people using it and their quality is 100x better. Mine is filled with artifacts and noise even though I am using manual exposure and a very low ISO setting. It gets even worse if I try to shoot in low light and is why I added a 50mm 1.4 f Lens to try and combat this but my issue has still not been reaolbed. Any help to what I am doing wrong or how do to fix this would be greatly appreciated, thanks.
