Q. I am looking to start a VLOG in my spare time, and I am looking for a solid and affordable 1080p webcam that has good quality video so that green screening won't look choppy. I am aware that I will need good lighting for the green screening, but that is taken care of, I have a good set up as long as the camera works well.
A. HD Camcorders and DSLR Cameras interpolate the video, which means of every 25 frames of video, 4 or 5 frames are taken by the lens assembly; the other frames in between these are filled in by the camcorder inner circuitry, thus giving you not true video. It looks like this -one frame from the lens assembly, 7or 8 from the electronic circuitry, one frame from the lens assembly, 7or 8 from the electronic circuitry, one frame from the lens assembly, 7or 8 from the electronic circuitry, one frame from the lens assembly, 7or 8 from the electronic circuitry, from front to back of the video. Near impossible to edit, even when you have the Multi port processor computer with the big 1GB Graphics card and a Sound card that is required to edit, view, watch and work with the files these camcorders produce.
Consumer Level HD Camcorders and DSLR Cameras have 4 problems. 1) Blurry, fuzzy, out of focus areas closely around people in videos taken by consumer level HD camcorders. 2) Any movement, even a wave or lifting an arm, while in front of a recording Consumer Level HD Camcorder and DSLR Cameras, results in screen ghosts and artifacts being left on the video track, following the movement. Makes for bad video, sports videos are unwatchable. 3) These Consumer Level HD Camcorders and DSLR Cameras all have a habit of the transferred to computer files are something you need to convert, thus losing your HD quality, to work with your editing software. 4) Mandatory maximum record times - 1 hour, 30 minutes, 8 minutes, 3 minutes – four different times advertised as maximum record time for some Consumer Level HD Camcorders and DSLR Cameras. No event I have ever been to is that short. Either take multiple camcorders and DSLR Cameras or pack up with out getting the end of the event on video.
MiniDV is currently the most popular format for consumer digital camcorders. MiniDV camcorders are typically more affordable than their HDD and DVD counterparts. Each MiniDV tape will typically hold an hour of footage at normal recording speed and quality. MiniDV tapes are available for purchase at not only electronic and camera stores, but also at drugs stores and grocery stores, making them easy to find while your on vacation. There are literally hundreds of MiniDV camcorders available; both in standard and high-definition. And add the fact that to get a HD camcorder that could produce better video quality footage, one would have to spend in excess of $3500 for that camcorder that could produce higher quality video

Will my Mini DV camcorder work well for green screen?
Q. I've heard that mini DV video cameras do not work well with green screen and that I need some other sort of camera. Is this true? And what should I be using if not a mini DV camera?
A. the way to get a good green screen is lighting the screen evenly and not having any shadows appear on it when standing in front of it. be at least 5 feet away from the screen. this will allow you to not cast shadows. The screen also needs to be large enough to frame you and the background that you want.
BE SURE TO USE A MONITOR. Don't trust your eyes. Your eyes are way more sensitive than your camera. You need to see what the camera sees for your keying project.
DV is more difficult to key because of its limited color space. 4:1:1. When you start shooting 4:2:2 or even 4:4:4, keying will become really easy. shadows and uneven lighting become much less of an issue.
