2D Video Oscilloscope.
Useful to measure spatial impulse, step responses, chroma delays, etc.
It accepts the following parameters:
- x
-
Set scope center x position.
- y
-
Set scope center y position.
- s
-
Set scope size, relative to frame diagonal.
- t
-
Set scope tilt/rotation.
- o
-
Set trace opacity.
- tx
-
Set trace center x position.
- ty
-
Set trace center y position.
- tw
-
Set trace width, relative to width of frame.
- th
-
Set trace height, relative to height of frame.
- c
-
Set which components to trace. By default it traces first three components.
- g
-
Draw trace grid. By default is enabled.
- st
-
Draw some statistics. By default is enabled.
- sc
-
Draw scope. By default is enabled.
Examples
-
Inspect full first row of video frame.
oscilloscope=x=0.5:y=0:s=1
-
Inspect full last row of video frame.
oscilloscope=x=0.5:y=1:s=1
-
Inspect full 5th line of video frame of height 1080.
oscilloscope=x=0.5:y=5/1080:s=1
-
Inspect full last column of video frame.
oscilloscope=x=1:y=0.5:s=1:t=1
