Isadora Manual v1.3 - TroikaTronix

Performance Monitor
Performance Monitor gives statistics about Isadora’s performance,
including the current average frame rate and video processing overhead.
Input Properties
• update: Sets the frequency at which the outputs are updated in cycles per
second (hertz). If you would prefer to trigger the outputs manually, you can
set this frequency to zero and use the trigger input instead.
• trigger: When triggered, updates the outputs.
Output Properties
• target fps: The target frame rate as set in the Isadora Preferences expressed in
frames per second (fps).
• fps: The average rate at which all stages are being updated, expressed in
frames per second (fps).
• cycles: The current cycle rate; the frequency with which Isadora is able to
process all active scenes, expressed in cycles per second.
• vpo: The current video processing overhead; this is the percentage of time
that Isadora spends performing video processing related tasks as compared to
the amount of time Isadora spends processing all tasks.
Picture Player
Generates a video stream from a picture imported into in the Media
Window.
The output of the picture player can be connected to any actor that has a video
input. Unlike the Movie Player, which sends a frame of video on a periodic basis
when the movie is playing, the Picture Player only sends a new frame of video
when 1) its Scene is activated, 2) its visible property goes from off to on, or 3) the
picture property changes from one valid picture to another.
