Problems solved by technology

[0003] However, when the existing video preview progress bar is displayed, the omitted picture information between the thumbnails is relatively large, and the video details that the user can preview are relatively few. When cutting the video according to this progress bar, It is difficult to precisely control the position of video cropping, and its video cropping accuracy is relatively low

Embodiment 1

[0056] figure 1 A flow chart of a video preview progress bar scaling method provided in Embodiment 1 of the present application is given. The video preview progress bar scaling method provided in this embodiment can be executed by a video preview progress bar scaling device. The video preview progress bar scaling method The device can be realized by means of software and / or hardware, and the video preview progress bar scaling device can be composed of two or more physical entities, or can be composed of one physical entity. Generally speaking, the video preview progress bar scaling device can be a smart terminal device such as a mobile phone, a tablet, or a computer.

[0057] In the following, the video preview progress bar scaling device is used as an example for performing the video preview progress bar scaling method for description. refer to figure 1 , the scaling method of the video preview progress bar specifically includes:

[0058] S110. Real-time detection of the s...

Embodiment 2

[0088] On the basis of the above examples, Figure 10 It is a schematic structural diagram of a video preview progress bar scaling system provided in Embodiment 2 of the present application. refer to Figure 10 The video preview progress bar scaling system provided in this embodiment specifically includes: a detection module 21 , a scaling module 22 and a display module 23 .

[0089] Wherein, the detection module 21 is used for real-time detection of the scaling operation of the first video preview progress bar;

[0090] The scaling module 22 is configured to respond to the scaling operation, calculate length information of the scaled first video preview progress bar, redraw the first video preview progress bar based on the length information, and obtain the corresponding second video preview progress bar strip;

[0091] The display module 23 is configured to re-extract the thumbnail of the current video and display it corresponding to the second video preview progress bar ...

Embodiment 3

[0095] Embodiment 4 of the present application provides an electronic device, referring to Figure 11 , the electronic device includes: a processor 31 , a memory 32 , a communication module 33 , an input device 34 and an output device 35 . Memory 32, as a computer-readable storage medium, can be used to store software programs, computer-executable programs and modules, such as program instructions / modules corresponding to the image preview sliding processing method described in any embodiment of the present application (for example, video preview progress detection module, zoom module and display module of bar zoom system). The communication module 33 is used for data transmission. The processor 31 executes various functional applications and data processing of the device by running the software programs, instructions and modules stored in the memory, that is, realizes the above-mentioned picture preview sliding processing method. The input device 34 can be used for receivin...

Abstract

The embodiment of the invention discloses a video preview progress bar zooming method, system and device and a storage medium. According to the technical scheme provided by the embodiment of the invention, the scaling operation of the first video preview progress bar is detected in real time, the length information of the scaled first video preview progress bar is calculated in response to the scaling operation, and the first video preview progress bar is redrawn based on the length information, so that the corresponding second video preview progress bar is obtained; and based on the corresponding relationship between the thumbnail width and the second video preview progress bar, re-extracting the thumbnail of the current video and displaying the thumbnail corresponding to the second videopreview progress bar. By adopting the technical means, the video preview progress bar can be zoomed, video preview details are increased by retaking the thumbnail, and the video cropping precision isimproved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a video preview progress bar scaling method, system, device and storage medium. Background technique [0002] Currently, in a video editing application, a progress bar previewing video thumbnails is usually provided for the user to select a node of the video editing. Wherein, when the video thumbnail preview progress bar is displayed, the corresponding relationship between the video duration and the progress bar width is defined, and the width occupied by each thumbnail is defined, and the number of video thumbnails is calculated. Then calculate the time interval for taking thumbnails according to the total video duration, take video zoom images according to the time interval, and tile them in the progress bar in order. The video preview progress bar displayed in this form can provide the user with certain psychological expectations when cutting...
