ComfyUI Node: Join Videos

Join Videos:

The JoinVideos node is designed to seamlessly combine multiple video and audio inputs into a single cohesive output. This node is particularly useful for creating complex video compositions by merging different video clips and their corresponding audio tracks. It allows you to input up to five sets of images and audio, which are then processed to produce a unified video and audio output. The node is highly beneficial for animation projects or video editing tasks where multiple sources need to be synchronized and combined efficiently. By leveraging this node, you can streamline your workflow, ensuring that all your video components are aligned and integrated smoothly.

Join Videos Input Parameters:

images_1

This is a required parameter that represents the first set of images to be included in the video. It serves as the primary visual input and is essential for the node's operation. The images provided here will form the base layer of the final video output.

audio_1

This optional parameter allows you to include an audio track that corresponds to the first set of images. If provided, this audio will be synchronized with the images_1 input, enhancing the multimedia experience of the final output.

images_2

An optional parameter for a second set of images. Including this allows for additional visual content to be merged into the final video. It provides flexibility in creating more complex video sequences.

audio_2

This optional parameter is for an audio track that corresponds to the second set of images. It ensures that any additional visual content is accompanied by its respective audio, maintaining synchronization across the video.

images_3

Another optional parameter for a third set of images. This allows for further expansion of the video content, enabling the inclusion of more diverse visual elements.

audio_3

An optional audio track for the third set of images. It ensures that the third set of visuals is paired with appropriate audio, contributing to a richer multimedia output.

images_4

This optional parameter allows for a fourth set of images to be included in the video. It provides additional layers of visual content, enhancing the complexity and depth of the final video.

audio_4

An optional parameter for an audio track that corresponds to the fourth set of images. It ensures that the fourth set of visuals is synchronized with its audio, maintaining the integrity of the multimedia presentation.

images_5

An optional parameter for a fifth set of images. This allows for the inclusion of even more visual content, offering maximum flexibility in video composition.

audio_5

This optional parameter is for an audio track that corresponds to the fifth set of images. It ensures that the final set of visuals is accompanied by its respective audio, completing the multimedia experience.

fps

This optional parameter specifies the frames per second for the final video output. It determines the smoothness and speed of the video playback. The default value is 30.0, with a minimum of 1.0 and a maximum of 120.0, allowing for a wide range of video playback speeds.

Join Videos Output Parameters:

images

This output parameter represents the combined set of images from all the input sources. It is the visual component of the final video, reflecting the integration of all provided image inputs into a single cohesive sequence.

audio

This output parameter is the combined audio track from all the input sources. It represents the synchronized audio component of the final video, ensuring that all provided audio inputs are merged into a unified soundtrack.

Join Videos Usage Tips:

• To achieve a smooth and cohesive video output, ensure that all image inputs are of similar resolution and aspect ratio. This will prevent any visual inconsistencies in the final video.
• When combining multiple audio tracks, consider the overall audio balance and volume levels to ensure that no single track overpowers the others, resulting in a harmonious audio output.
• Utilize the fps parameter to match the frame rate of your input images, ensuring that the final video playback is smooth and consistent with your project's requirements.

Join Videos Common Errors and Solutions:

Missing required input: images_1

• Explanation: The node requires at least one set of images to function, and this input is missing.
• Solution: Ensure that you provide a valid set of images for the images_1 parameter before executing the node.

Inconsistent image resolutions

• Explanation: The input images have varying resolutions, which can lead to visual discrepancies in the final video.
• Solution: Standardize the resolution of all input images to ensure a consistent visual output.

Audio synchronization issues

• Explanation: The audio tracks are not properly aligned with their corresponding image sequences.
• Solution: Double-check the timing and duration of each audio track to ensure they match the length and sequence of their respective image inputs.
