About shooting video with SLR?

Skills cannot be achieved quickly. The most important thing is to grasp the aperture and focal length. At present, there is no need for special grade, which requires a lot of late material and editing, which is more troublesome. Usually a video can be recorded for 30 minutes. This has nothing to do with the later period. If you can't splice the video, don't shoot the video. The general battery life is about 1 hour.
