Load Video UI - Custom Node to Trim, Resize, and Preview Videos in Realtime
New custom node bypasses 100MB limit, adds drag-and-drop and real-time preview.
ComfyUI users now have a powerful new tool for video preprocessing: the Load Video UI custom node by developer WhatDreamsCost. This node allows you to trim, resize, and preview videos directly within your workflow in real-time, all without requiring any additional libraries or dependencies. It directly addresses a major limitation of the default load video node, which is capped at 100MB files. With Load Video UI, you can load videos of any length and instantly see the trimmed segment play back, making it far easier to dial in exact start and end points for your AI video pipelines.
Beyond the core trimming and previewing, the node packs several quality-of-life features. It includes a toggle to switch between seconds and frame numbers, both in the UI widgets and the interface itself. For resizing, you can choose from four options: maintain aspect ratio, crop, stretch to fit, or pad. The node also supports drag-and-drop for quick file imports, shows a progress bar during loading, and is optimized to use less RAM than alternative solutions. All of this is available for free on GitHub, making it a must-try for any ComfyUI user working with video.
