Load Video Batch (Inputs/Outputs) MXD

Some jobs aren't "load a video," they're "load the forty videos in this folder and process them all." Load Video Batch (Inputs/Outputs) MXD is built for exactly that: it points at a folder under inputs or outputs, sweeps up every video inside - recursively, subfolders included - and hands the whole collection back as a batch in a single VIDEO list output. No per-file dropdown, no queue choreography. Pick a folder, and it's a batch.

How it works

You choose source (outputs or inputs) and a folder from a dropdown that lists only directories that actually contain video files - the pack filters out empty or irrelevant folders so you're not hunting through noise. The node then walks the folder tree, collects every file with a video extension (sorted for predictable order), and loads each one through ComfyUI's native video API into a list of VIDEO objects. The output is marked as a list, so downstream nodes see the batch rather than one item.

Inputs

• source - outputs or inputs, default outputs.
• folder - the subfolder to scan. The dropdown is pre-populated from both roots, and because it's recursive, "the folder" means "everything under it."

That's it. One output: VIDEO, as a list.

Wiring it in

The VIDEO list feeds batch video pipelines the same way a single VIDEO would - the pack's WAN 2.2 helpers and standard video conditioning nodes consume it per item. If your workflow is "process every clip in this renders folder," this is the loader you want; it's the natural partner to the single-file loader when you stop caring which individual file it is. For per-item naming, keep the single loader's filename output in mind - this batch node doesn't hand back filenames per clip, just the video data.

Installing

ComfyUI Manager → search "Maxed Out" → install, restart. Manual:

cd ComfyUI/custom_nodes
git clone https://github.com/Maxed-Out-99/ComfyUI-MaxedOut.git

No pip dependencies.

Common issues

Same requirement as the other video nodes: you need a recent ComfyUI with native video API support - on an old version it raises a clear "please update ComfyUI" error. Beyond that, the two things that bite are memory (loading a big folder of long clips materializes a lot of frames; keep folders sane or process in subfolder-sized chunks) and the empty-folder error - if there are no valid videos, it throws a FileNotFoundError telling you so rather than silently returning nothing.
