ComfyUI Node: 🎬 Video Encoder (FFMPEG)

FFMPEG Video Encoder [Dream]:

The FFMPEG Video Encoder [Dream] node is designed to convert a sequence of images into a video file using the powerful FFMPEG tool. This node is particularly useful for AI artists who want to create animations or video content from a series of generated images. By leveraging FFMPEG, the node ensures high-quality video output with customizable settings such as frame rate and file naming. Additionally, it offers the option to automatically remove the source images after encoding, streamlining the workflow and saving storage space. The main goal of this node is to provide a seamless and efficient way to produce video content from image sequences, making it an essential tool for animation post-processing.

FFMPEG Video Encoder [Dream] Input Parameters:

name

This parameter specifies the base name for the output video file. It is a string value with a default of "video". The name you provide will be used to generate the final video file name, ensuring that it is unique and does not overwrite existing files.

framerate_factor

This parameter adjusts the frame rate of the output video. It is a float value with a default of 1.0, a minimum of 0.01, and a maximum of 100.0. The frame rate factor multiplies the original frame rate of the image sequence, allowing you to speed up or slow down the video playback. For example, a factor of 2.0 will double the frame rate, making the video play faster.

remove_images

This boolean parameter determines whether the source images should be deleted after the video is successfully encoded. It has a default value of True. When set to True, the node will remove the images used to create the video, helping to manage disk space and keep your project directory clean.

FFMPEG Video Encoder [Dream] Output Parameters:

log_entry

This output parameter provides a log entry detailing the actions performed by the node, including the generation of the video file. The log entry is useful for tracking the node's operations and diagnosing any issues that may arise during the encoding process.

FFMPEG Video Encoder [Dream] Usage Tips:

• Ensure that the sequence of images is correctly ordered and named before using the node to avoid any issues with the final video output.
• Adjust the framerate_factor to achieve the desired playback speed for your video. Experiment with different values to find the best setting for your animation.
• Use the remove_images option to automatically clean up your project directory after encoding, especially if you are working with large image sequences.

FFMPEG Video Encoder [Dream] Common Errors and Solutions:

"Failed to setup MPEG Encoder - check parameters!"

• Explanation: This error occurs when the FFMPEG setup fails due to incorrect or missing parameters.
• Solution: Verify that all required parameters are correctly set and that FFMPEG is properly installed and accessible from your system's PATH.

"Generated video 'filename' not found"

• Explanation: This error indicates that the video file was not successfully created.
• Solution: Check the log entry for any errors during the encoding process and ensure that the output directory is writable and has sufficient space.

"File 'filename' not found"

• Explanation: This error occurs when one or more source images are missing or incorrectly specified.
• Solution: Ensure that all images in the sequence are present and correctly named. Verify the file paths and try again.

"Permission denied"

• Explanation: This error indicates that the node does not have the necessary permissions to read the source images or write the output video file.
• Solution: Check the file permissions for the source images and the output directory. Ensure that the node has the required read and write access.
