ComfyUI Node: Constrain Image for Video 🐍

Constrain Image for Video 🐍| Constrain Image for Video 🐍:

The ConstrainImageforVideo| Constrain Image for Video 🐍 node is designed to adjust the dimensions of an image to fit within specified maximum and minimum width and height constraints while maintaining the original aspect ratio. This node is particularly useful for preparing images for video production, ensuring that they meet specific size requirements without distortion. It offers the flexibility to crop images if necessary to fit within the desired dimensions, making it a versatile tool for AI artists who need to standardize image sizes for consistent video output. By using this node, you can automate the process of resizing and cropping images, saving time and ensuring uniformity across your video projects.

Constrain Image for Video 🐍| Constrain Image for Video 🐍 Input Parameters:

images

This parameter accepts a list of images that you want to constrain. Each image will be processed to fit within the specified size constraints while maintaining its aspect ratio.

max_width

This integer parameter sets the maximum allowable width for the images. The default value is 1024, and it must be a non-negative integer. If an image's width exceeds this value, it will be resized down to fit within this limit.

max_height

This integer parameter sets the maximum allowable height for the images. The default value is 1024, and it must be a non-negative integer. If an image's height exceeds this value, it will be resized down to fit within this limit.

min_width

This integer parameter sets the minimum allowable width for the images. The default value is 0, and it must be a non-negative integer. If an image's width is below this value, it will be resized up to meet this minimum requirement.

min_height

This integer parameter sets the minimum allowable height for the images. The default value is 0, and it must be a non-negative integer. If an image's height is below this value, it will be resized up to meet this minimum requirement.

crop_if_required

This parameter is a choice between "yes" and "no", with the default value being "no". If set to "yes", the node will crop the images to fit within the specified maximum dimensions if resizing alone is insufficient. This ensures that the images meet the exact size requirements.

Constrain Image for Video 🐍| Constrain Image for Video 🐍 Output Parameters:

IMAGE

The output is a list of images that have been resized and possibly cropped to fit within the specified maximum and minimum width and height constraints. Each image maintains its original aspect ratio unless cropping is required to meet the size limits.

Constrain Image for Video 🐍| Constrain Image for Video 🐍 Usage Tips:

• To ensure your images fit perfectly within a video frame, set the max_width and max_height to match your video resolution.
• If you need to maintain the aspect ratio without any cropping, set crop_if_required to "no".
• Use the min_width and min_height parameters to avoid images becoming too small and losing detail.

Constrain Image for Video 🐍| Constrain Image for Video 🐍 Common Errors and Solutions:

Image size exceeds maximum constraints

• Explanation: The image dimensions exceed the specified max_width or max_height.
• Solution: Ensure that the max_width and max_height parameters are set correctly and consider enabling cropping by setting crop_if_required to "yes".

Image size below minimum constraints

• Explanation: The image dimensions are below the specified min_width or min_height.
• Solution: Adjust the min_width and min_height parameters to appropriate values that match your requirements.

Invalid parameter values

• Explanation: One or more parameters have invalid values, such as negative integers.
• Solution: Verify that all integer parameters (max_width, max_height, min_width, min_height) are non-negative and within a reasonable range.
