摘要： The decode resolution of a video signal can be varied during decoding by decoding a first portion of a video signal at a first resolution; determining a second resolution, different from the first resolution, at which a second portion of the video signal is to be decoded; adjusting one or more reference pictures associated with the video signal to correspond to the second resolution; and decoding the second portion of the video signal at the second resolution. The second resolution, at which the second portion of the video signal is decoded, can be selected from a plurality of predetermined decoding resolutions in response to the detection of a predetermined condition or in response to an input received from a user. Additionally, one or more reference pictures associated with the video signal can be up-sampled or down-sampled in at least one of the horizontal direction and the vertical direction.

摘要： A video signal can be decoded at a reduced resolution by receiving a video signal encoded at a first resolution; determining a second resolution at which the received video signal is to be decoded, wherein the second resolution is lower than the first resolution; and decoding the received video signal at the second resolution. The second resolution can be selected from a plurality of predetermined decoding resolutions. Further, the second resolution can be selected in response to an input received from a user. Decoding of the received video signal can include scaling one or more reference pictures by a first scaling factor and scaling one or more non-reference pictures by a second scaling factor. Additionally, scaling can comprise transforming a first portion of frequency coefficients associated with a block of picture information and discarding a second portion of frequency coefficients associated with the block of picture information.

摘要： Some embodiments provide a method that receives the addition of a video clip to a composite video project. The video clip has a sequence of video images at a first frame rate and the composite video project has a second frame rate for outputting video images. When the first frame rate does not match the second frame rate but is within a threshold of the second frame rate, the method generates output video images for a particular duration of the composite video project at the second frame rate by using each of the video images of the video clip once during the particular duration. When the first frame rate is not within the threshold, generating output video images for the particular duration of the composite video project at the second frame rate by using at least one of the video images for each output video image over the particular duration.

摘要： Some embodiments provide a method that receives the addition of a video clip having a first set of spatial properties to a composite video project having a second set of spatial properties. When the first set of spatial properties and the second set of spatial properties are different, the method automatically applies a spatial conform effect to the video clip to conform images of the video clip to the second set of spatial properties. The method receives input to transform images of the video clip as displayed in the composite video project. The method stores the spatial conform effect and the received transform as separate effects for the video clip.

摘要： Some embodiments of the invention provide a media-editing application for creating and editing a media presentation that displays the results of edits as the edits are made to the media presentation. The media-editing application displays the movement of media clips of the media presentation as the media clips are being moved within the media-editing application to change the media presentation. Also, the media editing application in some embodiments can dynamically display the results of edits in a preview display area. That is, the media editing application has a preview generator that can generate previews of the media presentation on the fly as media clips are being dragged into and within the timeline. This allows the user of the media-editing application to see and hear the results of the operation while performing them.

摘要： Some embodiments provide a media-editing application that includes several background-rendering modules. These modules automatically render segments of a media presentation in the background of a system on which the media-editing application is being executed. By performing rendering in the background, the background-rendering modules produce rendered results for the segments. That is, the modules pre-generate playable media output data (e.g., composite video frames or audio samples) of the media presentation without interrupting other operations (e.g., editing operations, etc.) of the media-editing application. The background-rendering modules in some embodiments include a first background-rendering module and a second background-rendering module. The first background-rendering module determines a prioritized order in which the segments are to be rendered. The second background-rendering module renders the segments of each category in the prioritized order that is determined by the first background-rendering module.
