S3, the RGB data extracting pending picture from described PNG formatted data and alpha channel data, and the BMP form in video is inserted into according to above-mentioned two data genaration;
S4, obtain and be used for the snatch of music of generating video and background picture, and the feature of this snatch of music and background picture is analyzed, obtain the feature moment;
S5, based on obtain the feature moment, determine the switching instant of snatch of music and background picture, determine the switching instant of each pictures in snatch of music and background picture in the picture of generating video simultaneously;
S6, PNG formatted data based on pending picture, according to the switching instant determined, generate the animation of band background music and background picture;
S7, obtain one or more snippets pending video material and be processed into standard video file;
S8, the band background music of gained and the animation of background picture and standard video file anastomosing and splicing are generated short video set.
Preferably, the concrete steps of step S4 comprise:
Obtain snatch of music and background picture and obtain its not characteristic value in the same time;
According to predetermined characteristic value siding-to-siding block length, determine that at least one characteristic value of snatch of music and background picture is interval;
According to the interval order of predetermined characteristic value, the 5th stack features value is chosen according to characteristic value order from big to small successively from least one characteristic value interval, the quantity of the quantity in the moment corresponding to characteristic value wherein in the 5th stack features value to be n-1, n the be picture for generating video;
Using the moment corresponding in snatch of music and background picture for each characteristic value in the 5th stack features value as the feature moment.
Preferably, the concrete steps of described step S7 are:
The different video fragment got is carried out video standard conversion processing according to user to the order that material adds respectively, namely described video standard conversion processing is carried out frame sign process to described video segment and is carried out format code transferring again, thus the Video Quality Metric of different size is become established standards form.
Preferably, for generate animation picture in each pictures be greater than 0 the switching time in described snatch of music.
Preferably, in the feature moment of acquisition, first feature moment on snatch of music and the distance between the start time of described snatch of music are not less than first threshold.
Preferably, in the feature moment of acquisition, first feature moment on background picture and the distance between the start time of described snatch of music are not less than first threshold.
Preferably, the feature moment of snatch of music is decibel feature or frequecy characteristic or tonality feature.
Preferably, the feature of background picture is color characteristic or textural characteristics or shape facility or spatial relationship feature.
The present invention has following beneficial effect:
The plurality of pictures photographed in actual life and multistage video effectively can be spliced generation short video set, and background music, background picture, picture and video perfectly can be combined.
