Definitions
- This application relates to the field of data transmission technology, and in particular to a video file editing method, device, system, and computer-readable storage medium.
- users can take high-definition pictures and high-definition videos through shooting equipment, such as drones and cameras.
- the captured high-definition pictures and high-definition videos and other media files are stored on the shooting device.
- the media files on the shooting device need to be completely downloaded to local devices, such as PCs, smart phones and tablets, etc., and then the media files can be edited on the local devices.
- complete media files are usually large, take a long time to download, and the downloaded media files will take up a lot of storage space.
- the time for downloading media files is much longer than the time for editing media files, and the local device has insufficient storage space.
- the user experience is not good when the media file download fails.
- the preprocessed video file is sent to the terminal device for the terminal device to display a video file editing page containing the preprocessed video file, wherein the preprocessing includes adjusting the resolution of the video file, At least one of frame rate and format;
- the drone can be a rotorcraft.
- the drone may be a multi-rotor aircraft that may include multiple rotors. Multiple rotors can rotate to generate lift for the drone.
- the rotor can be a propulsion unit, allowing the drone to move freely in the air.
- the rotor can rotate at the same rate and/or can generate the same amount of lift or thrust.
- the rotor can rotate at different speeds at will, generating different amounts of lifting force or thrust and/or allowing the drone to rotate.
- one, two, three, four, five, six, seven, eight, nine, ten or more rotors can be provided on the drone. These rotors can be arranged such that their rotation axes are parallel to each other. In some cases, the rotation axis of the rotors can be at any angle relative to each other, which can affect the movement of the drone.
- the first preset threshold and the second preset threshold can be set based on actual conditions, which are not specifically limited in this application.
- the first preset threshold is 0.2m/s
- the second preset threshold is 10m/s. s.
- the user can further adjust the playback speed of the video file through the playback speed adjustment icon, which can increase the adjustment range of the playback speed of the video file.
- the download instruction of the target video file triggered by the user is acquired, and the target video file is downloaded from the shooting device according to the download instruction. Since the target video file is edited, and the size of the target video file is much smaller than the video file before editing, the time required to download the target video file is short, and the user does not need to wait for a long time, which greatly improves the user experience.
- the video file editing method provided by the foregoing embodiment obtains the editing parameter information of the video file sent by the terminal device, and executes the video file editing operation according to the editing parameter information to generate the target video file, so that the video file editing operation is performed on the side of the shooting device Completed, the performance requirements of the terminal device are low, which is convenient for users to edit video files under various terminal devices, and improves user experience.
- FIG. 7 is a schematic block diagram of a structure of a terminal device according to an embodiment of the present application.
- the video file editing page is displayed by the display device, wherein the video file editing page is loaded with a video file preprocessed by the shooting device, and the preprocessing includes adjusting the resolution, frame rate, and format of the video file. At least one of
- the target specification information is sent to the shooting device, so that the shooting device performs the preprocessing based on the target specification information, and transmits the preprocessed video file to a terminal device.
- the acquiring target specification information of the video file includes:
- the specification information of the target video file is sent to the shooting device, so that the shooting device performs a video file editing operation based on the editing parameter information and the specification information of the target video file to generate a target video file.
- the specification information includes at least one of the resolution, frame rate, aspect ratio, and format of the target video file.
- the processor is further configured to implement the following steps:
- the processor 401 may be a micro-controller unit (MCU), a central processing unit (CPU), a digital signal processor (Digital Signal Processor, DSP), or the like.
- MCU micro-controller unit
- CPU central processing unit
- DSP Digital Signal Processor
- the specification information includes at least one of the resolution, frame rate, aspect ratio, and format of the target video file.
- the editing parameter information includes editing parameters of a plurality of video clips, and the editing parameters of each video clip are the same or different.
- the display parameters include at least one of exposure, contrast, brightness, saturation, color temperature, sharpening, special effects, and filters of the video clip.
