Two changes to investigate a doubled-length output report:
1. Default save_metadata_png back to True (was False since 946e170).
The PNG sidecar carries the embedded workflow JSON — it's the
only audit trail when a render comes out wrong. Removing it by
default left no way to diagnose retroactively. Users who don't
want the sidecar can still toggle it off explicitly; ones who do
want auditability (most VFX pipelines) get it automatically.
2. One-shot diagnostic print() at the top of combine_video logging:
- input image batch size + shape
- audio sample count + sample rate -> seconds
- frame_rate -> expected video seconds
- pingpong + loop_count
This pins down whether a doubled-length output is the image stream
arriving already-doubled (workflow issue: ImageConcatMulti in batch
mode, an upstream pingpong, etc.) vs combine_video itself doing
something with the frames. To be removed in a follow-up once the
current report is diagnosed.

ComfyUI-Koolook
Kforge Labs for ComfyUI: a project-kit sidebar plus Koolook nodes for VFX, image, and video workflows.
Start here: KForge Labs ComfyUI-Koolook overview
That overview explains the sidebar, snapshots, saved workflows, modules, recovery tools, and included nodes for new users.
The main experience is the Kforge Labs sidebar. It helps you keep a project setup together: favorite nodes, saved workflows, reusable modules, tags, snapshots, and recovery tools.
Kforge Labs Sidebar
Use the sidebar as a reusable project kit.
| Feature | What it does |
|---|---|
| Snapshots | Save and load the whole Kforge Labs state: favorite nodes, workflows, modules, tags, archive, and recovery data. |
| Search | Find nodes, workflows, directories, and tags from one field. Tags keep exact capitalization, so Depth and depth can be separate folders. |
| Nodes | Keep favorite nodes close, grouped by theme or repository name. |
| Workflows | Save the whole script, save a selection of nodes, load workflows, or insert saved modules into the current canvas. |
| Recovery | Use autosaves, starter presets, snapshot library settings, and missing-pack install helpers. |
