Systems and methods for video editing

Abstract

Systems and methods are disclosed to edit video by receiving a source video; processing the source video with a plurality of tasks including one or more transitions, effects, and audio; assigning the tasks to a plurality of general purpose processor cores and/or a graphics processing unit (GPU); and rendering a video output.

1 . A process to edit video, comprising:
 receiving a source video on a handheld device, a tablet or a mobile phone;   generating a plurality of video or audio edit instructions to be applied to the source video;   assigning the tasks to a plurality of low power processor cores to process the video editing instructions in parallel on the processing cores and reduce power to the cores when not editing video; and   rendering video outputs.   
     
     
         2 . The method of  claim 1 , comprising running one or more instructions on a graphics processing unit (GPU). 
     
     
         3 . The method of  claim 2 , comprising using the cores and the GPU to accelerate a preview and rendering of motion, opacity, color, and image distortion effects. 
     
     
         4 . The method of  claim 1 , comprising deleting, moving, trimming, or splitting a video clip. 
     
     
         5 . The method of  claim 1 , comprising scaling the video clip to one of: DV, Digital Betacam, HDV, HDCAM, DVCPRO HD, and D5 HD. 
     
     
         6 . The method of  claim 1 , comprising capturing and editing HDV or HDTV content. 
     
     
         7 . The method of  claim 1 , comprising playing-back video in real-time. 
     
     
         8 . The method of  claim 1 , comprising adding music to the video. 
     
     
         9 . The method of  claim 1 , comprising storing the video on a computer. 
     
     
         10 . The method of  claim 9 , wherein the computer comprises a local computer or a remote computer. 
     
     
         11 . The method of  claim 1 , comprising uploading the video to a video server. 
     
     
         12 . The method of  claim 1 , comprising editing comprises switching multiple nestable timelines. 
     
     
         13 . The method of  claim 1 , comprising generating surround sound. 
     
     
         14 . A telephone, comprising:
 a camera to capture a source video;   a user interface to specify a plurality of video or audio edit instructions to be applied to the source video;   a plurality of low power processor cores to process the video editing instructions in parallel, wherein power to the cores is reduced when not editing video; and   a display coupled to the processor cores to render video outputs.   
     
     
         15 . The telephone of  claim 14 , comprising a graphics processing unit (GPU) to process the video or audio edit instructions. 
     
     
         16 . The telephone of  claim 14 , comprising code to run on the processor cores to delete, move, trim, or split a video clip. 
     
     
         17 . A mobile device, comprising:
 a camera to capture a source video;   a user interface to specify a plurality of video or audio edit instructions to be applied to the source video;   a plurality of low power processor cores to process the video editing instructions in parallel, wherein power to the cores is reduced when not editing video; and   a display coupled to the processor cores to render video outputs.   
     
     
         18 . The mobile device of  claim 17 , comprising a graphics processing unit (GPU) to process the video or audio edit instructions. 
     
     
         19 . A system, comprising:
 a plurality of low power processing cores;   a graphics processing unit (GPU) coupled to the plurality of the low power processing cores; and   code executable by the processor cores and the GPU to receive a source video; process the source video; and render a video output, wherein the code assigns the instructions to a plurality of low power processor cores to process the video editing instructions in parallel on the processing cores and reduce power to the cores when not editing video.   
     
     
         20 . A mobile device, comprising:
 a wireless cellular transceiver to transmit data;   a camera; and   a processor coupled to the camera and the wireless transceiver, the processor having code to:
 capture a video using the camera; 
 display frames of the video for editing; 
 select one or more frames to be cut; 
 select one or more transitions to be applied to the video; 
 select one or more audio tracks to add to the video; and 
 adjust the audio of the video. 
   
     
     
         21 . The mobile device of  claim 20 , comprising a graphics processing unit (GPU) coupled to the processor. 
     
     
         22 . The mobile device of  claim 20 , wherein the mobile device comprises one of: a tablet, a telephone, a camcorder.
