Why don’t videos at 1080p look anywhere near as clear as a photograph at 1080p?
The first thing is that virtually all (amateur) video is compressed, before it gets anywhere near YouTube. You could use a lossless codec if your camera has that ability (on some cameras you can set the quality), but the resulting file sizes would be massive. But before it even gets to that stage…
The Short Answer
The first thing is that virtually all (amateur) video is compressed, before it gets anywhere near YouTube. You could use a lossless codec if your camera has that ability (on some cameras you can set the quality), but the resulting file sizes would be massive. But before it even gets to that stage, the quality of the sensor has to be factored in. And that quality can usually be best described as: "Adequate". In low light levels, because the shutter speed can't usually be made faster than 1/33 sec (on NTSC) or 1/25 (on PAL), the frames are much more likely to end up grainy. But mostly, it's file size.
