Pull Source Value #

Pulls the last known value of a source. Will return 0 if the source doesn’t exist.
Very useful command to use together with Source: Motion commands. For example, you can pull the current X and Y position of a source and then use Source: Motion Position to smoothly move it across the screen.

Pull Type	Description	Possible values
X/Y position	returns X or Y position of the source	for example 500
X/Y scale	returns scale of the source that affects its width (X) and height (Y)	1 = 100% scale
Rotation	returns the degree of rotation of the source	0-360
Volume	returns the volume percentage of the source	0-100
Muted	returns boolean value whether the source is muted or not	0 for unmuted and 1 for muted
Visible	returns boolean value whether the source is visible or not	0 for not visible and 1 for visible

This command might not work correctly if the source is inside a group. It's recommended to use nested scenes instead.

Box Name	Type	Description
Scene	String	Scene name containing the source
Source	String	Source name to pull the value
Variable	String	Variable name to save the pulled value into
Pull	Dropdown menu	Type of the value you wish to pull

Source Change Visibility #

Changes the visibility of a source.

Changing visiblity of sources residing in groups has inconsistent results. It is advised to use nested scenes instead.

Box Name	Type	Description
scene-name	String (optional)	Scene name containing the source. Leave blank for current active scene.
item	String	Source name
visible	boolean	`True` for visible, `False` for not visible or `Toggle` to invert current visibility status Toggle should be used only if it’s a single button command.

Edit

Source Change Position #

Changes the position of a source.

Use Source Motion: Position command instead for a smooth transition.

Box Name	Type	Description
scene-name	String (optional)	Scene name containing the source. Leave blank for current active scene.
item	String	Source name
Field: X	Real (optional)	X position to set the source to. Can leave blank to not modify it.
Field: Y	Real (optional)	Y position to set the source to. Can leave blank to not modify it.

Edit

Source Change Scale #

Changes the size of a source.
Use negative values for a horizontal (mirror) or vertical source flip.
The way the source resized is based on source’s positional alignment in OBS (source-Transform-Edit Transform).

Use Source Motion: Scale command instead to change the size gradually.

Box Name	Type	Description
scene-name	String (optional)	Scene name containing the source. Leave blank for current active scene.
item	String	Source name to change size.
X Scale	Real (optional)	X Scaling to set the source to. Leave blank to not modify it. `1.0` is 100%.
Y Scale	Real (optional)	Y Scaling to set the source at. Leave blank to not modify it. `1.0` is 100%.

Edit

Source Change Rotation #

Changes the rotation of a source.
The center point of the rotation is based on the Positional Alignment option (source-Transform-Edit Transform).

Use Source Motion: Rortation command instead to change the rotation gradually.

Box Name	Type	Description
scene-name	String (optional)	Scene name containing the source. Leave blank for current active scene.
item	String	Source name to change rotation.
rotation	Real	Rotation angle to change the source to. `0` is normal, `180` is upside down, `360` is back normal

Edit

Source Change Volume #

Changes the volume of a source.

Use Source Motion: Volume command instead to change the volume gradually.

Box Name	Type	Description
source	String (optional)	Scene name containing the source. Leave blank for current active scene.
volume %	Real	Percentage to set the volume to, between 0 and 100.

Edit

Source Motion: Position #

Moves a source from point A to point B over a given duration.
If you want to move a source from its current position, you can use the command Math: Pull Source Value to find the current source’s X and Y position and incorporate it into this command.

The higher your Receiver's FPS (max 60) the smoother the animation is going to be.

Box Name	Type	Description
scene	String	Scene name containing the source
source	String	Source name to move
Start X	Real	Starting X position
Start Y	Real	Starting Y position
Final X	Real	Final X position
Final Y	Real	Final Y position
Dur.(MS)	Int	Duration of the transition in milliseconds
Smooth	dropdown	Type of transition. None = Normal, Out = Starts out fast and ends slow, In = Starts out slow and ends fast, In/Out= Starts out slow, gets faster and then slows down at the end again.

Edit

Source Motion: Position Curve #

Moves a Source from point A to point B over a given duration and curves it in a circle pattern.
You can make a source complete a half circle or have a slight curve in its transition.
If you want to move a source from its current position, you can use the command Math: Pull Source Value to find current source’s X and Y position and incorporate it into this command.

The higher your Receiver's FPS (max 60) the smoother the animation is going to be.

Box Name	Type	Description
scene	String	Scene name containing the source
source	String	Source name to move
Start X	Real	Starting X position
Start Y	Real	Starting Y position
Final X	Real	Final X position
Final Y	Real	Final Y position
Curve %	Real	The amplitude of the curve. Can be negative or over 100. 100% = perfect half circle, 0% = straight line with a slower start and slower finish. -200% elongated half circle on the opposite side.
Dur.(MS)	Int	Duration of the transition in milliseconds
Smooth	dropdown	Type of transition. None = Normal, Out = Starts out fast and ends slow, In = Starts out slow and ends fast, In/Out= Starts out slow, gets faster and then slows down at the end again.

Edit

Source Motion: Scale #

Resizes a source from Size A to size B over a given duration.
Due to the way the OBS source resizing work, the result might look a bit snappy sometimes.
The way the source is resized is based on what the source’s point of origin is set to in OBS.
You can use negative values for a horizontal (mirror) or vertical source flip.
You can use Math: Pull Source Value command to find current source’s X and Y size and incorporate it into this command.

The higher your Receiver's FPS (max 60) the smoother the animation is going to be.

Box Name	Type	Description
scene	String	Scene name containing the source
source	String	Source name to scale
Start Xscale	Real	Starting X size
Start Yscale	Real	Starting Y size
Final Xscale	Real	Final X size
Final Yscale	Real	Final Y size
Dur.(MS)	Int	Duration of the transition in milliseconds
Smooth	dropdown	Type of transition. None = Normal, Out = Starts out fast and ends slow, In = Starts out slow and ends fast, In/Out= Starts out slow, gets faster and then slows down at the end again.

Edit

Source Motion: Rotation #

Changes the rotation of a source over a set duration.
The center point of the rotation is based on the Positional Alignment option (right click on the source in OBS-Transform-Edit Transform).
You can use Math: Pull Source Value command to get the current rotation of a source and incorporate it in this command.

Box Name	Type	Description
scene	String	Scene name including the source.
item	String	Source name to change the rotation.
Start	Rotation	Real Starting Rotation. 0-360
Final	Rotation	Real Final Rotation. 0-360

Smooth	dropdown	Type of transition. None = Normal, Out = Starts out fast and ends slow, In = Starts out slow and ends fast, In/Out= Starts out slow, gets faster and then slows down at the end again.

Edit

Source Motion: Volume #

Changes the volume of a given source from volume A to B over a duration.
You can use Math: Pull Source Value command to get the current volume of a source and incorporate it in this command.

Edit

Source Motion: Alpha Filter #

Changes the transparency of a source over a set duration.
Requires a Color Correction filter to be added to your source.
This way you can gradually fade out a source before turning its visibility completely off and gradually fade in a source after turning its visibility on.

Older Color Correction filters require 0-100 range, however newer ones require 0-1 range.

Box Name	Type	Description
source	String Source name to change the transparency of.
filterName	String	Filter name. Must be a Color Correction filter.
Start Alpha%	Real	Starting transparency percentage. 0-100 or 0-1 depending on the filter’s version.

OBS gives no indication if a whole scene is muted by this command.

Box Name	Type	Description
Source	String	Source name to be muted. Can be a scene name as well.
mute	boolean	`True` for mute source, `false` for unmute source

Edit

Source Toggle Mute #

Inverts the mute status of a specified source.
