In order to make those skilled in the art more fully understand the technical solution in the embodiment of the present application, below in conjunction with the application
Attached drawing in embodiment, technical solutions in the embodiments of the present application are clearly and completely described, it is clear that described reality
It is the embodiment of the present application a part of the embodiment to apply example only, instead of all the embodiments.Based on the implementation in the embodiment of the present application
Example, the every other embodiment that those of ordinary skill in the art are obtained should all belong to the range of the embodiment of the present application protection.
Further illustrate that the embodiment of the present application implements with reference to the embodiment of the present application attached drawing.
Fig. 1 is the flow diagram of method for processing video frequency in the embodiment of the present application one；As shown in Figure 1 comprising following step
Rapid S101 and step S102：
Multi-frame video in S101, extraction video sequence, and determine the two adjacent frame videos for needing to carry out transition processing；
It, can be in step S101 when determining the two adjacent frame video for needing to carry out transition processing in the present embodiment
The two adjacent frame videos for needing to carry out transition processing are determined according to the frame number of video frame or the timestamp of video frame.
In the present embodiment, video sequence can be referred to as video flowing again, and the frame number of video frame can also be referred to as stream number.It carries
The different frame video taken can carry out caching process according to the size of stream number.
Need the adjacent two frames video for carrying out transition processing that can be provided by third party application by user man-machine
Operation interface is specified, can also be determined by way of automatic identification.Specifically, the mode of automatic identification is such as specifically led to
The histogram difference determination for calculating adjacent two frames video is crossed, therefrom chooses histogram difference and is more than given threshold corresponding adjacent two
Frame video is the object for needing to carry out transition processing, or also referred to as point, transition.
S102, the transition duration handled according to the timestamp of the two adjacent frame videos and transition, to described adjacent
Two frame videos and transition video synthesized and carried out the addition of transition subtitle.
In the present embodiment, in step S1020 to the adjacent two frame videos and transition video carry out synthesis include：It will
Transition video is shared in the two adjacent frame videos, the transition video in the two adjacent frame videos when sharing
Long summation is equal to the transition duration.
In addition, in the present embodiment, the addition that transition subtitle is carried out in step S102 includes：It carries out without plot subtitle, in love
Save the addition of at least one of subtitle and double exposure subtitle transition subtitle.
Specifically, for example two adjacent video frames are respectively video frame A and video frame B, and video frame A can be referred to as picture
Face, and video frame B can be referred to as into picture, if a length of 6s when the transition of setting, it is determined that the last 3s of video frame A and
The preceding 3s of video frame B, obtains 6s altogether.Certainly, merely illustrative herein, can also as the case may be, flexible configuration transition
Time length of the duration in front and back two frames video.In addition, it is necessary to explanation, the last 3s of video frame A before transition processing
Video content and the video content of preceding 3s of video frame B can intercept or delete in advance, in this way carry out transition when
It waits, directly transition video is inserted into according to the distribution of transition duration between video frame A and video frame B, then is synthesized, to
Complete the synthesis of video.In Video Composition, each subtitle in caption information list in content in subtitle can be believed
Breath item is converted to subtitle bitmap, accordingly, when carrying out the addition of transition subtitle, according to the resolution ratio of subtitle bitmap and synthesis
The brightness of pixel and Color Channel feature on video afterwards determine the point of addition on the video after the synthesis of transition subtitle.

The process of extraction multi-frame video processing in step S202 can refer to the record of above-described embodiment one, unlike, it carries
The multi-frame video taken is stored in a manner of two-dimensional array, and the serial number of two-dimensional array and the frame number of video frame correspond.
S203, the two adjacent frame videos for needing to carry out transition processing are determined；
In the present embodiment, due to there is the frame number of the serial number of two-dimensional array and video frame one-to-one correspondence, with reference to above-mentioned reality
Apply described in example one after manually or automatically method determines point, transition, can with the frame number of two frame video of direct neighbor or
The serial number of its corresponding 2-D data.
S204, the transition duration handled according to the timestamp of the two adjacent frame videos and transition, to described adjacent
Two frame videos and transition video synthesized and carried out the addition of transition subtitle；
It, specifically can be according to setting when the adjacent two frame videos and transition video are synthesized in the present embodiment
Whether Video Composition totalframes threshold decision, which synthesizes, is terminated, for example if the video totalframes after synthesis is equal to the total frame of Video Composition
When number threshold value, in the synthesis processing for terminating video.
It, can be first to the transition subtitle before the addition that transition subtitle is carried out in step S204 in the present embodiment
It is parsed to establish caption information list, is carried out further according to the address offset amount of caption information item in caption information list
The addition of transition subtitle.
