Load Video

Loads a video from ComfyUI's input folder as an IMAGE frame batch plus its audio. One responsive player shows the source and previews the selected trim. Drag the high-contrast IN and OUT handles below it, drag the selected range to move the whole window, or type exact seconds into the two fields. The playhead follows each edit, so the frame at either boundary is visible while trimming.

Playback is constrained to the selected window. LOOP repeats it; turn loop off and playback pauses at OUT. The reload button refreshes the source without creating a second preview. Tall videos use object-fit: contain, and the player height follows the node width with a compact lower bound.

Controls

• video: A file in the input folder; the upload button adds new ones.
• IN / start_seconds: Skip everything before this time.
• OUT / end_seconds: Stop at this time; 0 means the source end until a handle is moved.
• LOOP: Repeat the selected window during preview.
• ↻: Reload the selected source preview.
• custom_width / custom_height: 0 keeps the source size. Set one side only and the other follows the aspect ratio, rounded to an even number.

Outputs

• frames: Trimmed BHWC frame batch.
• audio: The same trim window; a silent track when the file has no audio.
• frame_count / fps / width / height / duration: Ready-made wiring for video combine nodes and info displays. duration covers the returned frames, not the whole file.

The trim window is decoded directly — untrimmed parts of the video are never loaded into memory.
