Load Video Advanced (Path)

The path-based half of the pack's video-loading pair. Load Video Advanced (Path) - class QwenVLUtils_VideoLoaderPath - is identical to Load Video Advanced except for one thing: instead of picking a file from ComfyUI's input folder, you type (or paste) a path to a video anywhere on your disk. No copying clips into ComfyUI/input, no managing the file through the UI.

Inputs and outputs

One input: file - a plain string field, with the placeholder X://insert/path/here.mp4 to show you the shape it expects. Two outputs:

• video - the video itself.
• path - the absolute file path string.

The mechanism is the same as its sibling: the source takes the path, resolves it through ComfyUI's annotated filepath handling, and builds the video via InputImpl.VideoFromFile(path). It also checks the file's modification time for IS_CHANGED, so the node re-runs when the file on disk changes.

Load Video Advanced vs. Load Video Advanced (Path)

Two loaders, one difference:

• Load Video Advanced reads from ComfyUI/input - use it for anything you've dropped into the UI.
• Load Video Advanced (Path) reads from an arbitrary path - use it for videos living anywhere else: a render scratch folder, a dataset directory, another drive.

Same two outputs, same native VIDEO type. The trade is convenience vs. reach: the input-folder version gives you a dropdown and upload, the Path version gives you every file on your machine.

The wiring caveat, same as its twin

Don't expect to plug this node's video output straight into a QwenVL node. The QwenVL nodes' video input is an IMAGE type - a batch of frames it uniformly samples - while this loader emits ComfyUI's native VIDEO object. To feed QwenVL video analysis you'd go through a frame-conversion step first, or route the path output where a path is consumed. And in the current release the QwenVL nodes' source_path input isn't wired into generation yet, so the path output is best used by other PATH-consuming nodes for now.

Install

Part of the QwenVL-Utils pack, installed the same way:

cd ComfyUI/custom_nodes
git clone https://github.com/AkihaTatsu/ComfyUI-QwenVL-Utils.git
cd ComfyUI-QwenVL-Utils
pip install -r requirements.txt

Or ComfyUI Manager → search "QwenVL Utils" → install → restart.

Troubleshooting

The "Invalid video file" error here almost always means a path typo, and Windows users get bitten by backslashes - the placeholder's X:// style hints at it: use forward slashes (C:/videos/clip.mp4) or escape the backslashes, because a raw C:\videos\clip.mp4 in the string field will not resolve the way you hope. If the path is right and it still fails, the file genuinely isn't a format ComfyUI can open, so check it plays in a normal player first.
