Problems solved by technology

[0005] Because the existing technology is limited to the above two processing methods when performing video processing, the processing method is relatively single, and because the processed video content is mainly concentrated in the title of the video, when the processed video is played, its visual effect has certain limitations

Embodiment 1

[0033] The present invention provides a method for processing video, see figure 1 , the method flow provided by this embodiment includes:

[0034] Step 101: Obtain the video to be processed;

[0035] Step 102: Perform primary encoding processing on the video to be processed to obtain a primary encoding result;

[0036] Further, the first-level encoding process is an axis-shifting filter encoding process;

[0037] Perform one-level encoding processing on the video to be processed to obtain the first-level encoding results, including but not limited to:

[0038] The video to be processed is encoded by the shift filter to obtain the encoding result of the shift filter.

[0039] Further, the method also includes:

[0040] Preset the rotation angle of the aperture;

[0041] Perform tilt-shift filter encoding on the video to be processed, including but not limited to:

[0042] According to the pre-set rotation angle of the aperture, the video to be processed is encoded with a ...

Embodiment 2

[0055] The embodiment of the present invention provides a method for processing video. Combining the content of the first embodiment above, the preset number of levels is two levels, the first-level encoding process is the axis-shift filter encoding process, and the second-level encoding process is accelerated encoding. The processing is taken as an example, and the video processing method provided by the embodiment of the present invention is described in detail. Among them, the axis-shifting filter encoding process can realize blurring around the video image of the video to be processed, that is, add edge blur effect to each frame image in the video; and the accelerated encoding process can achieve faster speed than normal playback speed Play the pending video. see figure 2 , the method flow provided by this embodiment includes:

[0056] Step 201: Preset the rotation angle of the aperture and the video playback speed;

[0057] Wherein, the preset rotation angle is used f...

Embodiment 3

[0078] An embodiment of the present invention provides a device for processing video, which is used to execute the method provided in the first or second embodiment above, see image 3 , the device consists of:

[0079] Obtaining module 31, for obtaining the video to be processed;

[0080] The processing module 32 is used to perform primary encoding processing on the video to be processed acquired by the acquisition module 31 to obtain a primary encoding result; perform secondary encoding processing on the basis of the primary encoding result to obtain a secondary encoding of the video to be processed result.

[0081] Further, the processing module 32 is also used to perform encoding processing at the current level on the basis of the encoding result of the previous level until the encoding result of the preset number of levels is obtained, and process the encoding result of the preset number of levels as the video to be processed the final processing result.

Abstract

The invention discloses a video processing method and device and belongs to the field of multimedia data processing. The method includes the following steps: obtaining a to-be-processed video; carrying out first-level coding processing on the to-be-processed video so as to obtain a first-level coding result; and carrying out second-level coding processing on the basis of the first-level coding result so that a second-level coding result of the to-be-processed video is obtained. The device includes an obtaining module and a processing module. Through carrying out multi-level coding processing on a to-be-processed video, the video processing method and device realize an objective that one processing method achieves a plurality of processing effects, enrich a video processing method and enable a visual effect to be better beautified when a processed video is played.

Description

technical field [0001] The invention relates to the technical field of multimedia data processing, in particular to a method and device for processing video. Background technique [0002] With the continuous progress of the society, it has become a hobby of many people nowadays to use electronic products such as mobile phones with camera functions for video shooting. After video shooting, people hope that various playback effects can be presented when the video is played. Therefore, in order to meet people's playback needs, how to process the captured video has become a key issue. [0003] When performing video processing in the prior art, there are two processing methods. The first method is to add text effects to the video to be played, and the added text can exist in any position of the video screen; the second method is to perform a layer mask on the video to be played, that is, to place the video screen of the video to be played on the In the set graphics screen. Fo...
