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 a graphics processing unit (GPU); and rendering a video output.

Claims

1. A process to edit video, comprising:

receiving a source video;

generating a plurality of tasks including one or more transitions, one or more effects, and one or more audio edit to be applied to the source video;

assigning the tasks to a plurality of general purpose processor cores and a graphics processing unit (GPU); and

receiving the outputs from the cores and the GPU; and

rendering a video clip as an output.

2. The method of claim 1, wherein each processor comprises a 64-bit processor having a compatible 32-bit mode to execute pre-existing 32-bit Windows software, and wherein the GPU comprises a graphics system.

3. The method of claim 1, comprising providing a point-to-point direct link between the processor and an Input/Output device.

4. The method of claim 1, comprising distributing tasks among the plurality of general purpose processors and the GPU to accelerate the preview and rendering of motion, opacity, color, and image distortion effects.

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 playing multiple video channels at full resolution and with titles, transitions, effects, and color correction.

9. The method of claim 1, comprising viewing multiple video tracks from a multicam shoot, and switching between tracks in real time.

10. The method of claim 1, comprising performing color correction.

11. The method of claim 1, comprising applying primary and secondary color-correction tools to match shots;

change colors;

correct exposure errors; and

modify highlights, midtones, and shadows across a clip, a sequence, or a project.

12. The method of claim 1, comprising editing comprises switching multiple nestable timelines.

13. The method of claim 1, comprising generating 5.1 surround sound.

14. The method of claim 1, comprising creating and manipulating multichannel audio to produce surround sound.

15. The method of claim 1, comprising generating interactive DVDs for digital dailies, test discs, or final delivery.

16. The method of claim 1, comprising

rendering transitions and effects using a first general purpose processor;

rendering audio using a second general purpose processor; and

rendering the video clip output using the GPU.

17. A system, comprising:

a plurality of general purpose processor cores;

a graphics processing unit (GPU) coupled to the plurality of general purpose processor 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.

18. The system of claim 17, comprising code to:

receive and edit HDV or HDTV content;

specify tasks to be applied to the content including transitions, effects, and audio;

assign the tasks to a plurality of general purpose processor cores and a graphics processing unit (GPU) to accelerate the preview and rendering of title, transition, motion, opacity, color, and image distortion effects; and

render a video output.

19. A telephone, comprising:

a camera; and

a processor coupled to the camera, 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.

20. The telephone of claim 19, comprising a graphics processing unit (GPU) coupled to the processor.
