Path Filename Resolved (Video)

Most filename builders hand you a template and let the saver resolve the tokens. Path Filename Resolved (Video) does the opposite: it resolves them, right in the node, using actual values you feed in. The output filename already says seed-1234, steps-30, cfg-7, and the real model name before it ever reaches a saver. That makes it the right choice when you're saving through a saver that doesn't know AUN's token syntax - like VHS Video Combine - or when you want to see the final name without running anything.

How it works

Structure is the usual: MainFolder (+ optional YYYY-MM-DD subfolder) + SubfolderA/SubfolderB, filename assembled from manual_name/auto_name (with the NameCrop/NameCropWords controls), prefixes, and suffixes, joined by delimiter. The difference is the optional inputs for actual values:

• model_short / model_name - the model name (short goes in the filename, full goes in the sidecar's model field).
• sampler_name, scheduler_name - sampler and scheduler strings.
• steps_value (INT), cfg_value (FLOAT), seed_value (INT) - the numbers, formatted as steps-<v>, cfg-<v>, seed-<v> (steps/cfg only when > 0, seed at 0 allowed).

The Model, Sampler, Scheduler, Steps, Cfg, Seed toggles decide which of those get included, and there's no way to include a token you haven't supplied a value for - it just skips it. You can wire these from an AUN Inputs node or an Extract Widget Value node to keep everything automatic.

The sidecar, which is the sleeper feature

There's an optional sidecar_format enum: choose Save to file and the node writes a .txt (or .json) next to the output in ComfyUI's output folder, documenting the main parameters. Either way the node always returns the sidecar text as its sidecar_text output. That's your poor-man's metadata - a text record of what made this video, without depending on video container metadata.

Outputs

• path_filename (STRING) - the fully resolved final path+name. Wire into VHS Video Combine or any saver that takes a path string.
• sidecar_text (STRING) - the sidecar content, usable or just displayable.

When to reach for it

If you save video via VHS (Video Helper Suite - the pack even acknowledges it as an inspiration) or any standard saver that can't parse %token% placeholders, this is the node that bridges your nice filename logic to that saver. It's the video sibling of the image-side AUN Filename Resolver Preview V2.

Install

Part of AUN ComfyUI Nodes (loz2754):

cd ComfyUI/custom_nodes
git clone https://github.com/loz2754/AUN-ComfyUI-Nodes

or via ComfyUI Manager, then restart. Deps (piexif, opencv-python-headless, imageio-ffmpeg, requests) install via Manager; ffmpeg (system or imageio-ffmpeg) is what actually encodes video. No model files.

The one thing to keep straight: if you wire actual values and a saver that also resolves tokens, you'll get doubled names (seed-1234_seed-1234). Pick one resolution layer - this node is the "resolve here" option, so turn off token resolution in the saver.
