ComfyUI Node: 👉 Linear Camera Pan

Linear Camera Pan [DVB]:

The Linear Camera Pan [DVB] node is designed to create smooth, linear panning effects in your video frames. This node allows you to move the camera across the frame in a specified direction, either horizontally, vertically, or diagonally, providing a dynamic and engaging visual experience. By adjusting the panning direction and mode, you can achieve various cinematic effects, such as moving from the center to the edge of the frame or vice versa. This node is particularly useful for AI artists looking to add motion to static images or enhance the storytelling aspect of their videos by guiding the viewer's focus across the scene.

Linear Camera Pan [DVB] Input Parameters:

frames

This parameter represents the set of video frames that you want to apply the panning effect to. It is essential as it provides the visual content that will be manipulated by the node.

output_width

This integer parameter defines the width of the output frames after the panning effect is applied. The default value is 512, with a minimum value of 1. Adjusting this parameter allows you to control the horizontal dimension of the final video output.

output_height

This integer parameter specifies the height of the output frames after the panning effect is applied. The default value is 512, with a minimum value of 1. This parameter helps you control the vertical dimension of the final video output.

direction_x

This float parameter determines the horizontal direction and magnitude of the pan. A positive value moves the camera to the right, while a negative value moves it to the left. The default value is 1.0. Adjusting this parameter changes the horizontal movement of the camera.

direction_y

This float parameter sets the vertical direction and magnitude of the pan. A positive value moves the camera downwards, while a negative value moves it upwards. The default value is -1.0. Modifying this parameter alters the vertical movement of the camera.

pan_mode

This parameter allows you to choose the panning mode from three options: "edge to edge," "center to edge," and "edge to center." Each mode defines a different starting and ending point for the pan, affecting how the camera moves across the frame. Selecting the appropriate mode helps you achieve the desired visual effect.

Linear Camera Pan [DVB] Output Parameters:

frames

This output parameter represents the set of video frames after the panning effect has been applied. It retains the same type as the input frames but with the added motion effect, providing a dynamic and visually engaging result.

Linear Camera Pan [DVB] Usage Tips:

• To create a smooth horizontal pan, set direction_x to a positive or negative value and direction_y to 0.
• For a vertical pan, adjust direction_y and set direction_x to 0.
• Experiment with different pan_mode settings to achieve various cinematic effects, such as starting the pan from the center or the edges of the frame.
• Ensure that the output_width and output_height are smaller than the input frame dimensions to avoid warnings about output size.

Linear Camera Pan [DVB] Common Errors and Solutions:

WARNING: Cannot pan - output larger than input!

• Explanation: This warning occurs when the specified output dimensions are larger than the input frame dimensions, making it impossible to perform the pan.
• Solution: Ensure that the output_width and output_height are smaller than the dimensions of the input frames.

WARNING: Cannot pan - no direction!

• Explanation: This warning is triggered when both direction_x and direction_y are set to 0, resulting in no movement.
• Solution: Set either direction_x or direction_y (or both) to a non-zero value to define the panning direction.
