Embodiment
For enabling above-mentioned purpose, the feature and advantage of the application more become apparent, below in conjunction with the drawings and specific embodiments, the application is described in further detail.
Embodiment one
With reference to Fig. 1, it illustrates the processing method of a kind of video image described in the embodiment of the present application one, comprising:
Step 101: put needing the primary video material of editor on the time line.
Timeline is made up of track, primary video material is put in track and edits, track is divided into the orbital head containing some attributes of track and the track container all primary video materials put in track, timeline is longitudinally being made up of track from level to level, wherein timeline is being laterally time shaft, and represent the length information of timeline, the primary video material on track will arrange in time-axis direction order, will first broadcast on the time shaft left side, below by rear broadcast.
Step 102: select to act on behalf of rank according to the editing environment of primary video material, obtain the video material after process.
Agency can comprise for set computer hardware resource, by other edit mode of agents level, can realize carrying out live preview and smooth editor to high-quality video, after importing browser by primary video material, do not need material transcoding, as long as select to act on behalf of rank, live preview and direct editing can be carried out to primary video material.
Act on behalf of rank and larger primary video material can be compressed to very little video file, eachly act on behalf of the corresponding a kind of compress mode of rank, wherein, to act on behalf of rank be the compress mode of 1/2nd correspondences is by the length of video and widely compresses according to 1/2nd, such as: when primary video material length is 1024, wide is 2048, be two when acting on behalf of rank/for the moment, primary video material length after compression is 512, and wide is 1024, namely primary video material can be diminished by acting on behalf of rank.
Primary video material is generally all larger, because the computer hardware resource of different clients is different, therefore in order to make the video material after client process more clear, therefore need to select different to act on behalf of rank according to the editing environment of primary video material, rank of acting on behalf of according to selecting carries out compression process to primary video material, obtains the video material after process.
Video material after process still can reflect the feature of primary video material, and the size of the video material just after process diminishes than primary video material size.
Video material after process can be kept in internal memory or in database, does not do concrete restriction to this application.
Step 103: decode operation is carried out to the video material after process.
Decoder is used to carry out decode operation to the video material after process.
Step 104: judge whether the decode operation of described decoder supports agency, if support agency, then performs step 105.
Step 105: according to acting on behalf of rank, the video material after process being decoded, obtaining decoded video material.
The video material obtained after decoding is low quality video material.
Step 106: described decoded video material is carried out video editing, generating video image.
After video clipping completes, by the primary video material on agency's link return time line, the primary video material on timeline is exported according to video editing, thus achieve the video actions that editing completes and be synchronized to primary video material.
Step 107: the video image generated is exported.
Pass through the present embodiment, timeline is placed on by needing the primary video material of editor, select different to act on behalf of rank according to the editing environment of primary video material, obtain the video material after process, then decode operation is carried out to the video material after process, if decode operation support is acted on behalf of, then according to acting on behalf of rank, the video material after process is decoded, obtain decoded video material, and video editing is carried out to decoded video material, generating video image, by selecting according to the editing environment of primary video material different to act on behalf of rank, other compression of different agents level is carried out to primary video material, thus solve the problem that the impact of computer hardware resource on Video processing cause poor user experience.
