• Device Movie Length and default window size configured in Setup > Output.
If your window size is the same as the Setup > Output default size, this is the maximum
number of frames shown.
If you set your window size to be smaller than the default size, then you are shown
more frames, since the same amount of memory is allocated for movies.
If you set your window size to be larger than the default, you get fewer frames.
• Max Time determines the maximum possible span of the movie. This limits the number
of frames.
• The number of frames available on disk. To see this, check the Time icon.
Flush the Loop Buer
The loops are "sticky". The frames are kept in a loop buer so the loop does not have to
reload if it stops and restarts. This is convenient when you are working with long loops.
If you make a change to the window such as the color scale or the Display Options, the
buer automatically "flushes" and the loop reloads your changes.
If your loop must be flushed and reloaded or your loop buer becomes corrupted, use the
Flush button to refresh the buer. The loop reloads the next time it starts.
Previous/Next
Single step forward and back through the loop. This is similar to using the Time Slider or
using the left/right arrow keys on the keyboard (with your cursor in the image area).
Toggle
Swaps between the current image and the previous image on the display, regardless of the
image type or time. Sometimes this is useful for comparing 2 dierent products (for
example, TOPS and VIL).
Display both products, then use the Toggle icon to alternately display each one.
It is convenient that when the cursor is used, the position is displayed correctly in the 2
toggle frames, even if their scales are radically dierent.
Skip Time
If you want to loop a long time series of data, for example, say 24 hours, you must usually
necessary skip some frames so that you can display the entire 24-hour span without
exceeding your Device Movie Length for the maximum number of frames.
