ComfyUI Node: 📺 Vintage TV

📺 Vintage TV:

The VintageTVNode is designed to transform your digital images into nostalgic representations reminiscent of vintage television screens. This node is perfect for artists looking to add a retro aesthetic to their work, simulating the look and feel of old CRT televisions, black and white screens, or even security monitors. By applying various effects such as scan lines, curvature, static noise, and phosphor glow, the node emulates the imperfections and unique characteristics of vintage TV displays. This can enhance your creative projects by providing a distinctive, aged look that evokes a sense of nostalgia and authenticity.

📺 Vintage TV Input Parameters:

image

This parameter represents the input image that you want to transform using the vintage TV effects. It is the primary source material for the node's processing.

tv_type

This parameter allows you to select the type of vintage TV effect you want to apply. Options include "crt_color" for color CRT effects, "crt_bw" for black and white CRT effects, "old_tv" for a general old TV look, and "security_monitor" for a security monitor appearance. The default option is "crt_color".

scan_lines

This parameter controls the intensity of the scan lines effect, which mimics the horizontal lines seen on old TV screens. It ranges from 0.0 to 1.0, with a default value of 0.5. Increasing this value will make the scan lines more pronounced.

curvature

This parameter adjusts the curvature effect, simulating the rounded screen edges of vintage TVs. It ranges from 0.0 to 1.0, with a default value of 0.3. A higher value will increase the curvature, giving a more pronounced rounded appearance.

static_noise

This optional parameter adds static noise to the image, emulating the random noise often seen on old TV screens. It ranges from 0.0 to 1.0, with a default value of 0.1. Increasing this value will add more noise to the image.

phosphor_glow

This optional parameter controls the phosphor glow effect, which simulates the glow of phosphor dots on CRT screens. It ranges from 0.0 to 1.0, with a default value of 0.2. A higher value will enhance the glow effect.

brightness

This optional parameter adjusts the brightness of the image, allowing you to fine-tune the overall lightness. It ranges from 0.5 to 1.5, with a default value of 0.9. Increasing this value will make the image brighter.

contrast

This optional parameter modifies the contrast of the image, affecting the difference between light and dark areas. It ranges from 0.5 to 2.0, with a default value of 1.1. A higher value will increase the contrast, making the image more vivid.

📺 Vintage TV Output Parameters:

IMAGE

The output is an image that has been transformed with the selected vintage TV effects. This output retains the nostalgic characteristics of old television screens, providing a unique and artistic representation of the original input image.

📺 Vintage TV Usage Tips:

• Experiment with different tv_type settings to find the vintage effect that best suits your artistic vision.
• Adjust the scan_lines and curvature parameters to achieve the desired level of authenticity in replicating old TV screen characteristics.
• Use the static_noise and phosphor_glow parameters sparingly to avoid overwhelming the image with effects, maintaining a balance between vintage aesthetics and image clarity.

📺 Vintage TV Common Errors and Solutions:

"Invalid image input"

• Explanation: This error occurs when the input image is not in a supported format or is corrupted.
• Solution: Ensure that the input image is a valid and supported image file format, such as JPEG or PNG.

"Parameter out of range"

• Explanation: This error indicates that one or more parameters have been set outside their allowable range.
• Solution: Check the parameter values and ensure they fall within the specified minimum and maximum limits.

"Unsupported tv_type option"

• Explanation: This error arises when an invalid tv_type option is selected.
• Solution: Verify that the tv_type parameter is set to one of the supported options: "crt_color", "crt_bw", "old_tv", or "security_monitor".
