Extracting Images from a Video Tape
By recording a clip or still image stored on a video tape as
a single clip (single file) under certain rules, you can
automatically extract an image from the clip, and save as a
separate frame memory file.
Relation between recorded state of video
tape and files after extraction
The extraction is carried out according to the following
rules.
Example 1: When only video signal clips and a
still images are recorded (single files)
V: video
Red: red marker frame
a)
Single video tape
Result of extraction:
Each section surrounded by red marker frames is extracted
as a clip (main file). If the red markers surround a single
frame, then it is extracted as a still image.
In the case above, two clip files (main files) and one still
image file are extracted.
Example 2: When a video signal clip is followed
by a key signal clip with the same number of
frames (pair file)
V: video
K: key
Red: red marker frame
a)
Blue: blue marker frame
b)
Single video tape
Result of extraction:
The section surrounded by red marker frames is extracted
as the main file, and the section surrounded by blue marker
frames is extracted as the sub file.
In the case above, one clip file (pair file) is extracted.
a)
A red marker frame is a monochrome frame with the RGB signal levels at
b)
A blue marker frame is a monochrome frame with the RGB signal levels
at 0%, 0%, 100% respectively.
