Abstract
Abstract An electronic video processing system comprises a store for storing data defining plural video clips, and a processor for selecting from the stored video clips a plurality of clips and for selectively combining data defining the selected clips to form data defining a video story. A plurality of representative frames respectively representing selected video edits is displayable to portray a portion of the video story. Also, for each selected clip, a frame representative thereof is displayable together with a pair of smaller frames derived from the first and last frames of the clip.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
135 words
An electronic video processing system comprising: a store for storing data defining a plurality of video clips each comprising one or more video frames; a user operable input device; a processor connected to the input device and the store and responsive to operation of the input device for selecting from the stored video clips a plurality of clips and for selectively combining data defining the selected clips to form data defining a video story; and a display connected to the processor for displaying images defined by data output from the processor, wherein the processor is responsive to the user operable device to output data defining for selected video clips a respective representative frame, the processor thereby causing the display to display a plurality of representative frames which together comprise a portion of the video story.
Claim 2
Dependent Claim
31 words
A system as claimed in claim 1, wherein the processor is operable to cause the display to display a cursor at a position determined by manipulation of the user operable device.
Claim 3
Dependent Claim
40 words
A system as claimed in claim 2, wherein a representative frame is selectable by the cursor, the processor being arranged to respond to further manipulation of the cursor by displaying another frame in the represented clip as the representative frame.
Claim 4
Dependent Claim
24 words
A system as claimed in claim 3, wherein the processor is arranged to display other frames in response to sideways movement of the cursor.
Claim 5
Dependent Claim
42 words
A system as claimed in claim 1 or 2, wherein the processor is arranged to cause the display to display each said representative frame together with a respective indicator which indicates the position of the representative frame in its respective video clip.
Claim 6
Dependent Claim
70 words
A system as claimed in claim 5, wherein a representative frame is selectable by manipulating the cursor relative to the indicator displayed with the representative frame, the processor being arranged to respond to further movement of the cursor both by replacing the selected representative frame with an other frame of the represented clip and by adjusting the indicator to indicate the location of the other frame in the represented clip.
Claim 7
Dependent Claim
42 words
A system as claimed in claim 6, wherein the indicator comprises an elongated strip and the processor is arranged to display said other frames and change the length of the strip in response to movement of the cursor lengthwise of the strip.
Claim 8
Dependent Claim
29 words
A system as claimed in claim 5, 6 or 7, wherein the indicating means is a distinctively marked narrow strip displayed on the display alongside the displayed representative frame.
Claim 9
Dependent Claim
57 words
A system as claimed in claim 2 or any of claims 3 to 8 as dependent thereon, wherein the processor is arranged to output data representing plural frames of a clip for display in sequence on the display, thereby to enable selection of a representative frame for display on the display separately from the clip represented thereby.
Claim 10
Dependent Claim
37 words
A system as claimed in claim 9, wherein the processor is arranged to output data defining an associated indicator which indicates the position of the representative frame in the represented clip for display with the representative frame.
Claim 11
Dependent Claim
31 words
A system as claimed in claim 9 or 10, wherein the displayed representative frames and their associated indicators are displayed in an area of the display as a sequence of frames.
Claim 12
Independent Claim
71 words
A system as claimed in any preceding claim, wherein the processor is responsive to the user operable device to output data defining the start and end frames of each selected video clip for display together with the respective representative frames as a pair of reduced sized frames on the display, the start and end frames of the clip of the associated representative frame being displayed as a sequence on the display.
Claim 13
Dependent Claim
57 words
A system as claims in claim 12, wherein the data defining the start and end frames is output together with further date defining the representative frames, thereby enabling the display to display the representative frames in one display area and simultaneously to display the sequence of representative frames and start and end frames in another display area.
Claim 14
Dependent Claim
72 words
A system as claimed in claim 12 or 13, wherein the sequence of representative frames is displayed as a column of frames together with the respective indicators displayed as narrow, distinctively marked strips between pairs of the representative frames and said reduced size frames are displayed as a column of frames alongside the column of representative frames, each pair of reduced size frames occupying the vertical height of the associated representative frame.
Claim 15
Dependent Claim
93 words
A system as claimed in claim 12, 13 or 14, wherein the data defining the video story comprises data representing one or more selected frames of each clip, and the processor is so arranged to respond to manipulation of the user operable device that movement of the cursor relative to a chosen reduced size frame causes the representative frame associated with the chosen reduced size frames to sequence through the selected frames of the corresponding clip and also through frames beyond the selected frames, of the clip not used in the video story.
Claim 16
Dependent Claim
84 words
A system as claimed in claim 2 or any of claims 3 to 15 as dependent thereon, wherein the user operable device is a pen and tablet device and movement of said cursor is effected by holding the pen under pressure in contact with the tablet and moving the pen relatively to the tablet whilst said pressure is maintained. A system as claimed in claim 16 as dependent on claim 15, wherein selection of the frames being sequenced occurs when said pressure is relieved.
Claim 17
Independent Claim
36 words
A system as claimed in any preceding claim, further comprising access means connecting the store with the display, which access means is capable of transferring video data at video rate between the display and the store.
Claim 18
Independent Claim
29 words
A system as claimed in any preceding claim, wherein the processor comprises a separate video processor and a display processor incorporated together with a display store in the display.
Claim 19
Independent Claim
67 words
A system as claimed in any preceding claim, wherein the display is arranged to display the representative frames in a user selected order as a column of frames in an area of the display, and the processor is arranged to combine selectively the data defining the video clips in an order corresponding to the user selected order of the representative frames in the displayed column of frames.
Claim 20
Dependent Claim
62 words
An electronic video editing system for combining a plurality of video edits each comprising a sequence of one or more video frames selected from a plurality of video clips so that the combined video edits form a video story, in which system a plurality of representative frames respectively representing selected video edits is displayable to portray a portion of the video story.
Claim 21
Dependent Claim
57 words
An electronic video editing system for editing a video clip comprising a sequence of video frames to form a video edit comprising plural frames selected from the sequence, in which system a frame representative of the video edit is displayable together with a pair of smaller frames derived from the first and last frames of the edit.
