We are hiring videographers and we noticed that some of their videos have colors that appear extremely far away from accurate color reproduction as well as highly pixelated/grainy quality despite 1080p resolution. It reminds me of my old cellphone cameras where it has a low megapixel value and it would end up very grainy.
It was most likely that they used wrong compression or a wrong file format or it because they had bad equipment to begin with. We are looking for professional quality videos similar to the one shown below where it has good color accuracy and the video looks HD with no flickering and pixels flying around:
Budget constraints are taken into consideration as extremely high end camera equipment is probably too way off the budget. What we are looking for is a good enough camera that can reproduce quality similar to the sample video shown. It is very difficult to have an idea of which camera can produce quality videos given there are a lot of options in the market and first hand experience is needed to tell if it is good or not. But there may be a criteria that video production people look for to know which equipment can produce quality videos.
