Load Video Pixaroma

What it does

Loads a video from ComfyUI's input folder and turns it into a batch of image frames you can feed into any image or video workflow. A video preview plays on the node body so you can check the clip without leaving ComfyUI.

The size of the chosen video is shown on the top left of the node, beside the outputs, so you can see what you are working with at a glance. That is the size of the source file; if you set custom_width or custom_height the frames come out at that size instead, and the width and height outputs always report what actually leaves the node.

The details you usually need are built in as separate outputs, so you do not need a second 'video info' node.

How to use

• Click choose video to upload to add a file from your computer, or pick one from the dropdown (use the arrows to flip through).
• Wire video_frames into an image or video node. To rebuild a video later, send video_frames and audio straight into Save Mp4 Pixaroma.
• The clip plays in the preview as soon as it is selected, no need to run first.

Loading controls

Max frames

How many frames to load from the start of the video. 0 = all. The safety valve for long clips: it never reads more than this many. Works with Skip first frames, which trims frames off the front of that window (Max 100 with Skip 5 gives 95).

Force FPS

Force a steady frames-per-second by dropping or duplicating frames (a 60fps clip forced to 24). 0 = keep the original rate. AI video models usually expect a fixed rate.

Skip first frames

Skip this many frames from the start, like trimming an intro. Trims the front of the loaded frames. The audio output is cut the same way (and to Max frames), so the sound stays in sync with the picture.

Custom width / height

Resize each frame as it loads. 0 = keep original. Set one to scale proportionally; set both to crop-to-fill that exact size (keeps proportions and trims overflow, like Resize Crop). It never stretches.

Outputs

video_frames

The video as a batch of image frames.

audio

The soundtrack (empty if the file has none). Wire into Save Mp4 to keep the sound.

frame_count

How many frames were loaded.

fps

Frames per second of the loaded clip.

width / height

Frame size in pixels, after any resize.

duration

Length of the loaded clip in seconds.

Requirements

Load Video reads frames with PyAV (or imageio as a fallback) and gets audio with ffmpeg. Most ComfyUI setups already have these, so usually there is nothing to install. If you ever see a 'video reader' message, install PyAV: in ComfyUI Manager use its pip install option and enter av (portable Windows: run python_embeded\python.exe -m pip install av in your ComfyUI folder).
