Extract
The tools in the Extract group of the Gallery ribbon can be used to create new images out of extracted frames from sequences displayed in the gallery view.
The tools in the Extract group are described below.
Extract: Use
this tool to extract frames from a sequence into new images. For
example, you can show a sequence of frames in the gallery view, click
on the frame(s) you want to extract, and click the Extract tool. The
extracted frame(s) appear as a new image in the application workspace,
as shown below.
Click the down arrow of the Extract tool to show the drop-down menu which has the following options:
- Extract: Click this tool to extract the currently-selected frames into a new image sequence.
- Extract Frame By Frame: Click this tool to extract the currently-selected frames into new images frame by frame (that is, a new image created for each frame).
Average: Click this tool to create a new image that represents an average of the currently-selected frames.
Difference: Click this tool to subtract frames from frames. If you select multiple frames, then the resulting image sequence will be a sequence of subtracted frames. The following options control how the output is formatted:
- "Wrap" - This option calculates the last frame as the difference between the last and first frames. For example, if you selected frames 1, 2, 3, 4, and 5, then the resulting sequence will contain (2-1), (3-2), (4-3), (5-4), and (1-5).
- "Diff Only" - This option returns only difference frames. The result will be one frame shorter than the original. For example, if you selected frames 1, 2, 3, 4, and 5, then the resulting sequence will contain (2-1), (3-2), (4-3), and (5-4).
- "Pad First" - This option returns only difference frames, but pads the result with the first frame of no difference. For example, if you selected frames 1, 2, 3, 4, and 5, then the resulting sequence will contain 1, (2-1), (3-2), (4-3), and (5-4).
- "Pad Last" - This option returns only difference frames, but pads the result with the last frame of no difference. For example, if you selected frames 1, 2, 3, 4, and 5, then the resulting sequence will contain (2-1), (3-2), (4-3), (5-4), and 5.
