Video Dump Frames

Straight talk on this one: it's not called out by name in the WAS Node Suite README's own node list, unlike most of the pack's nodes, so what follows leans more on what the node's name and its neighbors tell you than on the author's own description. Going by the naming convention the rest of the suite's video tools use - Write to Video, Create Video from Path, Create Morph Image from Path - Video Dump Frames does the inverse of assembling a video: it takes a video file in and writes its individual frames back out, presumably as an image sequence or batch you can then process frame-by-frame with the rest of ComfyUI's image tooling.

Why that matters for how you'd use it

If you want to run any per-frame processing on an existing video clip - restyling, upscaling, running it through a filter chain - you generally need it as a batch of individual images first, since ComfyUI's image nodes work frame-by-frame, not on video containers directly. A frame-dumping node is the standard first step in that kind of pipeline: pull the clip apart into frames, do your image-space work, then reassemble with something like the suite's Create Video from Path or Write to Video once you're done.

The constraint that actually is documented

What the README is explicit about, in its Video Nodes section covering this whole family of tools: they require FFMPEG installed and configured (with the ffmpeg path set in was_suite_config.json), and the author states plainly that official support is Windows-only - "I do not have access to Mac or a stand-alone linux distro." Linux and Mac users report mixed results; it may well work if your ffmpeg install is sane, but you're off the documented, tested path if you're not on Windows.

Installing it

Through ComfyUI Manager: search "WAS Node Suite", install, restart. Manually:

cd ComfyUI/custom_nodes
git clone https://github.com/WASasquatch/was-node-suite-comfyui
cd was-node-suite-comfyui
pip install -r requirements.txt

On top of the suite's own requirements, make sure FFMPEG itself is installed and its path is set correctly in was_suite_config.json (generated the first time you run ComfyUI with the suite installed) - the video nodes won't function without it.

Troubleshooting

If nothing happens, or you get an unclear failure, check the FFMPEG path first - that's the single most common point of failure across every video node in this suite, not specific to this one. If you're on Linux or Mac, be extra suspicious of anything video-related failing silently; that's exactly the unsupported territory the author flags.

And as with the rest of the pack: WAS Node Suite hasn't had active development since December 2023, so a broken import after a ComfyUI update is far more likely to be a pinned dependency conflict suite-wide than anything specific to this node.
