* feat(easy_image_batch): source_batch + source_frames list + selected_* outputs Three-mode input system, two new "selected only" outputs, and an alpha output convention that's explicit about its role. Inputs - source_batch (IMAGE, optional): pre-batched stack, e.g. straight from Load Video. - source_frames (multiline STRING): VFX frame numbers separated by commas, newlines, spaces or any mix. Picks from source_batch and places at the same timeline position. Removes the 4-keyframe ceiling. - placeholder_color: now offers Black / Gray / White (was Black / Gray). - invert_alpha (BOOLEAN, default off = "inpaint"): flips alpha to compositing convention (selected=white) when on. - image1 is now optional (you can drive the node entirely from source_batch + source_frames). At least one of image1 or source_batch must be connected. - start_frame default changed from 0 -> 1 to match VFX 1-based numbering. Mode rules - Mode 1 -- per-slot images: connect imageN, set imageN_frame. - Mode 2 -- source_batch + 4 slots: when imageN is unconnected, imageN_frame doubles as the source pick index AND timeline target. - Mode 3 -- source_batch + source_frames list: when the list is non-empty, the 4 slots contribute ONLY where imageN is explicitly connected -- the imageN_frame defaults (0, 4, 8, 12) do NOT pick from source_batch in this mode, so the list fully controls the selection unless an imageN override is wired. - Priority: source_frames list runs first; manual slots run after and override at the same target index. Output dedup is automatic (set-based). Outputs - image_batch (IMAGE): full timeline with placeholders. Unchanged. - alpha_batch (MASK): renamed from mask_batch; same default convention (selected=0.0/black, empty=1.0/white) so existing wires work unchanged. Toggle invert_alpha for compositing-style. - selected_image_batch (IMAGE, NEW): only the keyframes that landed, packed back-to-back in timeline order. Empty (length 0) if none placed. - selected_frames (STRING, NEW): comma-separated VFX frame numbers, sorted ascending and deduped. Same format as the source_frames input -- round-trips into another easy_ImageBatch instance. Docs - Updated class docstring with input modes + worked example (surfaces in ComfyUI's node tooltip). - New per-node user guide: docs/user_guide/nodes/koolook_image/easy_image_batch.md. - docs/user_guide/README.md graduates easy_ImageBatch from "TBD" to a real link. - CHANGELOG: Unreleased Added/Changed entries cover the full change set. Backward compatibility - Existing workflows wired to image_batch + mask_batch keep working; the second output slot position is unchanged. - The 4-keyframe screenshot pattern (source_batch + 4 slots, no list) is unchanged in behaviour. - start_frame default change affects only newly added nodes; saved workflows keep the value they were saved with. Co-authored-by: Cursor <cursoragent@cursor.com> * feat(easy_image_batch): cut window — rename start_frame -> cut_start_frame, fix source-pick math The 2nd output of Easy Image Batch (Koolook) gets a built-in cut window, replacing the workflow pattern of feeding the output through an external ImageFromBatch (batch_index, length) slicer. Conceptual rename - `start_frame` -> `cut_start_frame` everywhere. - The output now represents VFX frames [cut_start_frame .. cut_start_frame + total_frames - 1]. - Frames placed outside the cut window are dropped from the cut silently and listed in a single end-of-run summary log (replaces the previous per-frame "out of range" warnings). Math fix (real bug) The previous code conflated source pick index and output index under a single `target_index = vfx - start_frame`. That happened to work when start_frame=1 (source pick index = vfx - 1, by coincidence), but produced a wrong source pick whenever start_frame != 1. Now: source pick index = vfx_frame - 1 # hardcoded VFX 1-based output (cut) index = vfx_frame - cut_start_frame # cut window The two are validated independently: - source-side range error -> per-frame warning ("VFX frame N doesn't exist in source_batch") - output-side range -> silent drop, collected into the end-of-run summary Defaults - cut_start_frame=1 (was start_frame=1, so default behaviour for source_batch starting at VFX frame 1 is identical). - total_frames default 16 -> 81 (matches typical VFX shot length). - imageN_frame defaults 0/4/8/12 -> 1/5/9/13 (valid 1-based). - imageN_frame min 0 -> 1 (frame 0 is invalid under VFX 1-based). Console summary Always logged so it's easy to confirm what the node produced. Shape: [easy_ImageBatch] cut window: frames 41..121 (81 frames). 6 placed; 2 outside cut: 1, 27. Docs - Class docstring rewritten with the cut-window model + Examples A (cut_start_frame=1, no cut) and B (cut_start_frame=41, cut). - docs/user_guide/nodes/koolook_image/easy_image_batch.md fully updated to match. - CHANGELOG: new "Changed" entry under [Unreleased] explaining the rename, math fix, defaults bump, and migration notes. Migration notes for users of the previous PR commit - Saved workflows that had start_frame=1 (the default) keep producing identical output -- the math is unchanged in that case. - Saved workflows that set start_frame to a non-1 value will see different source picks (the old code was actually picking the wrong source frame, the new code picks correctly). Re-check those. Co-authored-by: Cursor <cursoragent@cursor.com> * feat(easy_image_batch): shift imageN_frame defaults to 5/9/13/17 The previous 1/5/9/13 cluster put all four default keyframes inside the first 13 frames of an 81-frame timeline. Shifting to 5/9/13/17 keeps the same stride-of-4 but leaves a small gap at the start, which reads cleaner in the node UI and gives a more representative spread of where keyframes commonly land. Updates the doc table and CHANGELOG bullet to match.

User Guide
End-user documentation for nodes shipped by ComfyUI-Koolook. Pages
mirror the ComfyUI category each node lives under, so the structure here
matches what you see when you type "koolook" in the node-add menu.
Each per-node page includes a Source block at the top that records whether the node is Koolook-native or imported from a fork — so fork attribution is visible without needing a fork-shaped directory tree.

Cross-cutting concepts
Pages here cover ideas that span more than one node:
- Kforge Labs sidebar guide — visual onboarding for Snapshots, favorite nodes, saved workflows, reusable modules, tags, and recovery.
- VAE encode/decode pairing — which encoder fields must match the decoder for a clean roundtrip, with worked examples for SDR / HDR / cinema-log / video workflows.
- HDR modes deep dive — what
Clip (SDR),Soft Clip,Compress (Log), andPassthroughactually do to your pixels before they hit the VAE, with per-pixel worked examples.
When to add a guide
A node deserves a page if it has any of:
- Non-obvious input semantics (e.g. aspect-ratio strings, frame indexing conventions).
- A workflow recipe more useful than the per-input tooltips.
- A known limitation or compatibility caveat.
- An encode/decode or input/output pairing relationship with other nodes.
Convention:
- One markdown file per canonical node ID, named after the ID
(
easy_hdr_vae_encode.md,easy_image_batch.md). - Place it in the folder that matches the node's ComfyUI category.
- Screenshots and helper images go in
img/, named to match the page they're embedded in (e.g.easy_hdr_vae_encode_pairing.png).
Where to find the canonical node ID list
The repo README.md lists all currently-registered
node IDs and display names. The historical inventory (including removed
nodes) is in the CHANGELOG.md.
