Nodes related to video workflows

Converts a video file into a series of images

video: The video file to be loaded
force_rate: Discards or duplicates frames as needed to hit a target frame rate. Disabled by setting to 0. This can be used to quickly match a suggested frame rate like the 8 fps of AnimateDiff.
force_size: Allows for quick resizing to a number of suggested sizes. Several options allow you to set only width or height and determine the other from aspect ratio.
frame_load_cap: The maximum number of frames which will be returned. This could also be thought of as the maximum batch size.
skip_first_frames: How many frames to skip from the start of the video after adjusting for a forced frame rate. By incrementing this number by the frame_load_cap, you can easily process a longer input video in parts.
select_every_nth: Allows for skipping a number of frames without considering the base frame rate or risking frame duplication. Often useful when working with animated gifs A path variant of the Load Video node exists that allows loading videos from external paths step resize If Advanced Previews is enabled in the options menu of the web ui, the preview will reflect the current settings on the node.

Loads all image files from a subfolder. Options are similar to Load Video.

image_load_cap: The maximum number of images which will be returned. This could also be thought of as the maximum batch size.
skip_first_images: How many images to skip. By incrementing this number by image_load_cap, you can easily divide a long sequence of images into multiple batches.
select_every_nth: Allows for skipping a number of images between every returned frame.

A path variant of Load Image sequence also exists.

Combines a series of images into an output video
If the optional audio input is provided, it will also be combined into the output video

frame_rate: How many of the input frames are displayed per second. A higher frame rate means that the output video plays faster and has less duration. This should usually be kept to 8 for AnimateDiff, or matched to the force_rate of a Load Video node.
loop_count: How many additional times the video should repeat
filename_prefix: The base file name used for output.
- You can save output to a subfolder: subfolder/video
- Like the builtin Save Image node, you can add timestamps. %date:yyyy-MM-ddThh:mm:ss% might become 2023-10-31T6:45:25
format: The file format to use. Advanced information on configuring or adding additional video formats can be found in the Video Formats section.
pingpong: Causes the input to be played back in the reverse to create a clean loop.
save_output: Whether the image should be put into the output directory or the temp directory. Returns: a VHS_FILENAMES which consists of a boolean indicating if save_output is enabled and a list of the full filepaths of all generated outputs in the order created. Accordingly output[1][-1] will be the most complete output.

Depending on the format chosen, additional options may become available, including

crf: Describes the quality of the output video. A lower number gives a higher quality video and a larger file size, while a higher number gives a lower quality video with a smaller size. Scaling varies by codec, but visually lossless output generally occurs around 20.
save_metadata: Includes a copy of the workflow in the output video which can be loaded by dragging and dropping the video, just like with images.
pix_fmt: Changes how the pixel data is stored. yuv420p10le has higher color quality, but won't work on all devices
