What is video frame extraction? Introduction of video frame extraction.
1. Video frame extraction is to extract several frames from a video at regular intervals, simulating the process of taking a photo at regular intervals and splicing it into a video (that is, shooting at low speed). It will feel different from simply fast-forwarding.
2. The effect of video frame extraction is often confused with time-lapse photography and low-speed photography. The difference between them is that time-lapse photography is a method of taking pictures, low-speed photography is a method of taking videos, and frame extraction is a means of later video.
3. Time-lapse photography is essentially an exposure at regular intervals, and the images formed by each exposure are superimposed (synthesized) on the same picture. If it is a film machine, it is a negative that has been exposed many times at the same time interval.
