What does the delayed video of the driving recorder mean?

Time-lapse photography is also called time-lapse photography and time-lapse video. English is time-lapse photography, which is a method of compressing time. At present, it is also called time-lapse video.

Time-lapse photography originated from special effects in film shooting. The movie takes advantage of human visual delay to play 24 photos a second, thus forming the illusion of dynamic pictures. It is one of the laws of film development that the plot changes from slow rhythm to fast rhythm. After the appearance of fast-paced action movies and disaster movies, people are not satisfied with seeing fleeting wonderful pictures. Cinematographers have developed the techniques of fast shooting and slow playing.

When shooting, adjust the number of photos taken by the film camera per second, so that the number of photos taken per second is much larger than 24, and then play them at the normal frame rate. The original high-speed action was broken down, that is, slow motion. The technology of shooting movies in slow motion is called high-speed photography.

Matters needing attention

Stability is very important, so the camera must be firmly fixed on a solid tripod to avoid camera shaking and shooting failure due to wind and other reasons.

Avoid unnecessary debris from entering the picture, such as shooting on the road. In order to prevent pedestrians from entering the picture, be sure to put the camera away from the sidewalk.

Prepare enough spare batteries and memory cards. Time-lapse shooting usually takes several hours or even dozens of hours, so you must prepare enough accessories according to the length of the required material. If conditions permit, it is best to turn on the alternating current to shoot.

Pay attention to the protection of the machine, because it takes a long time. In order to protect the safety of the camera and avoid the damage caused by natural and man-made factors, we must take good care of the camera during time-delay shooting to avoid exposure and low temperature.
