s3: determining the scale precision of a video time axis based on the sliding speed, wherein the greater the sliding speed is, the greater the scale precision is;
s4: determining the progress control duration of a video time axis based on the scale precision and the sliding distance of the sliding gesture;
s5: and playing and controlling the video based on the progress control duration.
According to the video playback method, the scale precision of the video time axis is flexibly adjusted by detecting the sliding speed of the sliding gesture of the user, the larger the sliding speed is, the larger the scale precision is, the longer the user slides the video time axis correspondingly adjusted by the same distance is, for example, when the sliding speed of the user is 2cm/s, the scale precision is 60min/cm, so that the user can adjust the video progress time in a large range when the user slides quickly; the smaller the sliding speed is, the smaller the scale precision is, for example, when the sliding speed of a user is 0.5cm/s, the scale precision is 1min/cm, so that the user can accurately adjust the video progress time when sliding at a low speed, the user can rapidly and accurately position the accurate progress time when playing back video, the playback picture of a certain time can be easily operated when the user is positioned and checked on a relatively long video, and the user experience is improved.
In order to simplify the determination manner of the scale precision, in some alternative embodiments, n sequentially increasing scale precision and n sequentially increasing reference speed ranges are preset, wherein the scale precision corresponds to the preset speed ranges one by one;

Of course, the scale accuracy and reference speed range configurations are not limited thereto, and those skilled in the art can select other suitable designs in light of the teachings of the present application, without limitation.

s20: and acquiring the sliding distance of the sliding gesture in a preset time interval, wherein the sliding speed is the ratio of the sliding distance of the sliding gesture to the time interval.
The time interval can be 1s, 2s or 3s, and the like, so that the corresponding scale precision can be adjusted along with the change of the sliding speed of the user, the user can more quickly adjust the progress time of the video recording, and the user experience is improved.
