ausboss ac0bb08949 Help pages: say what the nodes do today
32 of the ? help pages checked against the code and corrected.

Wrong claims fixed: Stitch Inpaint's empty-area check (20/255), what a
new video keeps on both Video Crop + Rotate + Pad pages, Load Video's
frame picker and player height, where Run Timer lists earlier runs,
inpainting on the Krea 2 Outpaint Model Patch page, Workflow Note's
banner layout and pack detection, Image Resize's pad bars and mask,
Save Image's path preview and tags, Free Memory's steps, and Latent
Size's sockets.

Image Crop + Rotate + Pad now follows the node from top to bottom; the
saved values no row shows moved under Technical details.

Controls are named the way the node shows them, with the input name
beside. Pages that opened with jargon now open with what the node does
and when to use it. LoRA Loader gained the Civitai lookup, suggested
strength and the gear options it did not name.

Select Every Nth

Keeps every nth frame of an IMAGE batch — halve a video's frame count before an expensive stage, or thin a long sweep down to samples.

Controls

  • images: The BHWC batch to thin out.
  • Every nth (nth, starts at 2): Keep one frame in every nth. 2 keeps every other frame, 1 keeps everything (useful with Offset alone to drop leading frames).
  • Offset (offset, starts at 0): Frames to skip before the first kept frame. With nth 2, offset 0 keeps frames 1, 3, 5 and offset 1 keeps frames 2, 4, 6 (one-based, as the rest of the pack counts frames).
  • fps (optional socket): The batch's frame rate, such as Load Video's fps output.

Outputs

  • images: The kept frames, in their original order.
  • fps: The wired rate divided by nth, so the kept frames still span the same time; 0 when no fps is wired.

An offset at or past the end of the batch stops with the batch's size instead of returning an empty batch, which no downstream node could use.
