Abstract

Multi-media project editing methods and systems are described. In one embodiment, a project editing system comprises a multi-media editing application that is configured to enable a user to combine multiple different video clips into a video project. A bitmap processor coupled with the multi-media editing application receives a first bitmap that can be used to render a transition between video clips and automatically processes the first bitmap to provide a different transition between video clips. Processing of the first bitmap can include, without limitation, using the first bitmap to provide an entirely new and different second bitmap, or processing the first bitmap in a manner which renders a transition that is different from the transition defined by the first bitmap. In one embodiment, a user is able to enter one or more parameters, through a user interface (UI), with the parameters then being used to manipulate the first bitmap to provide the different transition. Processing of the first bitmap can include many different operations, among which can be included one or more of: stretching, shrinking, replication, and offsetting. In addition, the first bitmap can be processed to include, in the transition it defines, a border that is not otherwise defined by the first bitmap.

Claims

1. A video rendering system comprising:

a memory;

one or more processors coupled to the memory;

a video application operable on the one or more processors configured to enable a user to combine multiple different video clips; and

a bitmap processor operatively coupled with the video application and configured to receive a first bitmap that can be used to render a transition between video clips and automatically process the first bitmap to provide a second bitmap that can be used to render a different transition between video clips and that is different from the first bitmap, the first bitmap having a respective range of values and the second bitmap having a respective range of values, the respective ranges of values of the first and the second bitmaps being the same.

2. The video rendering system of claim 1, the bitmap processor comprises modules selected from a group consisting of:

a shrinking and stretching module that is configured to shrink or stretch, respectively, the first bitmap;

a replication module that is configured to replicate the first bitmap;

an offset module that is configured to provide a transition that is offset from a transition provided by the first bitmap; and

a border module that is configured to provide a border in a transition defined by the first bitmap.

3. The video rendering system of claim 1, the bitmap processor is configured to receive one or more parameters provided by a user and use those parameters to process the first bitmap.

4. The video rendering system of claim 3, the bitmap processor is configured to use the one or more parameters to change the structure of the first bitmap.

5. A computer-implemented method of displaying a video comprising:

selecting a first bitmap that defines a first transition that can be used to transition between video clips;

operating upon the first bitmap to provide a second bitmap that can be used to render a second transition that is different from the first transition by using one or more parameters that are provided by a user, the parameters being used to operate upon the bitmap, the first bitmap having a respective range of values and the second bitmap having a respective range of values, the respective ranges of values of the first and the second bitmaps being the same; and

effecting the second transition between video clips.

6. The computer-implemented method of claim 5, said operating comprises one or more of:

stretching the first bitmap;

shrinking the first bitmap;

stretching and shrinking the first bitmap;

replicating the first bitmap;

offsetting the first bitmap; and

providing a border that is used in connection with the second bitmap to effect the second transition.

7. A computer-implemented method of displaying a multi-media editing project comprising:

receiving one or more parameters from a user, the parameters being associated with a multi-media editing project and relating to a transition that can be applied between two video clips in the project;

selecting a first bitmap that defines a first transition that can be used to transition between the video clips;

operating upon the first bitmap to provide a second bitmap that can be used to render a second transition that is different from the first transition by using the one or more parameters, the first bitmap having a respective range of values and the second bitmap having a respective range of values, the respective ranges of values of the first and the second bitmaps being the same; and

effecting the second transition between video clips.

8. The computer-implemented method of claim 7, said operating comprises one or more of:

stretching the first bitmap, shrinking the first bitmap, replicating the first bitmap, offsetting the first bitmap, and providing a border that is used in connection with the second bitmap to effect the second transition.

9. The computer-implemented method of claim 7, said method further comprises:

selecting the first bitmap comprising multiple pixels, each pixel being capable of having one of a number of predetermined of gray scale values, the first bitmap being configured for use in effecting the first transition between two videos in a multi-media editing project;

rescaling the second bitmap to ensure that pixels of the second bitmap have, collectively, all of the predetermined gray scale values; and

using the second bitmap in the second transition between at least two videos.

10. A multi-media project editing system comprising:

a memory;

a software implemented bitmap processor, coupled to the memory, configured for use in connection with a multi-media editing application to effect a transition between different videos, the bitmap processor being configured to;

receive one or more parameters from a user;

select a first bitmap that is to be used to render a first transition between two videos;

operate upon the first bitmap in accordance with the one or more parameters to provide a second bitmap that can be used to render a second transition that is different from the first transition, the first bitmap having a respective range of values and the second bitmap having a respective range of values, the respective ranges of values of the first and the second bitmaps being the same; and

apply the transition between two videos.

11. The multi-media project editing system of claim 10, the bitmap processor is configured to rescale the second bitmap so that it contains a predetermined number of gray scale values.

12. The multi-media project editing system of claim 10, the bitmap processor can operate upon the first bitmap by one or more of the following:

stretching the first bitmap;

shrinking the first bitmap;

stretching or shrinking the first bitmap;

replicating the first bitmap;

offsetting the first bitmap; and

providing a border within a transition that is defined by the second bitmap.

13. A software-implemented method of displaying a multi-media editing project comprising:

providing a user interface (UI) through which a user can enter one or more parameters that can be used to manipulate a bitmap-defined transition;

receiving one or more parameters that are entered by a user via the UI;

selecting a first bitmap associated with the one or more parameters entered by the user;

automatically operating upon the first bitmap to provide a second bitmap that is different from the first bitmap by using the one or more parameters that are provided by a user, the first bitmap having a respective range of values and the second bitmap having a respective range of values, the respective ranges of values of the first and the second bitmaps being the same, said operating comprising performing one or more of the following operations on the first bitmap;

stretching, shrinking, replicating, and offsetting; and

using the second bitmap in a transition between at least two videos.
