When editing a video, why do you lose frames when the video is accelerated?

You should use frame sampling. This kind of acceleration, if it is accelerated too fast, will lead to frame extraction in the video, which will lead to what you call video frame loss and rigid picture action.

Generally speaking, if the acceleration is too fast, it is suggested to mix the frames of the picture, which will make the picture relatively smooth.

Frame drop generally refers to the phenomenon that the frame rate is too low because the hardware is not enough to load the frequency of dynamic display and display screen refresh, which leads to the picture stagnation (or short time or long time).

Film editing is to screen, select, decompose and combine a large number of materials shot in film production, and finally complete a work with clear meaning, distinct theme, strong artistic appeal and coherence.

Starting from American director Griffith, the art of editing was produced by using the method of lens shooting and then connecting these lens groups. Editing is an indispensable work in the process of film production, and it is also the last re-creation in the process of film art creation. French new wave film director Godard: editing is the official beginning of film creation.
