Video editing operator interface for aligning timelines
First Claim
1. A method for time aligning a first video sequence with a second video sequence, the method comprising the steps of:
- representing the first video sequence with a first timeline oriented along a first axis;
representing the second video sequence with a second timeline oriented parallel to the first timeline, the second timeline being displaced from the first time line along a second axis;
marking a location on the second timeline with a reference time mark;
marking a location on the first timeline with an active time mark;
responding to an operator input by automatically time aligning the first timeline with the second timeline so that the active time mark and the reference time mark are aligned along the second axis with a same point on the first axis.

Abstract
An operator interface for a video editing system provides a visual sense of the content of video sequences, as well as their length, while also providing enhanced interactive control of locations and time alignments of the video. As the video sequence is processed into the system, a small but representative sample of each frame is saved in a local memory, while the video itself is stored in mass storage. These samples are used to provide a video pictorial timeline of the underlying stored video. The location of an operator'"'"'s view into the video sequence is controlled by a cursor'"'"'s movement along a detailed video pictorial timeline, a reverse motion area and a forward motion area to provide VTR control for location changes on the video tape. The cursor'"'"'s movement can be controlled by a mouse or a knob. Icons, either static or dynamic, are produced within the motion areas to indicate the amount of selected velocity. Timelines can be marked with time marks, roughly aligned and then automatically fine aligned by the system according to their respective time markers. The editing results associated with these timelines are also time aligned as a result of this process.
