Repeat Images 🎥🅥🅗🅢

Repeat Images (class name VHS_DuplicateImages) tacks copies of an image batch onto itself so the sequence repeats. Feed it a batch and a multiplier of 3 and you get that batch back-to-back three times. In video terms: take a short loop and make it longer by repeating it, or turn a single still into a run of identical frames.

Simple node, but it solves a real "the counts don't line up" problem that comes up constantly once you're stacking frames.

Why you'd reach for it

Two situations come up again and again. First, padding: some node downstream expects a specific frame count, and you're a few frames short - repeat the batch to reach the length you need. Second, holding a still: you've got one image and a video pipeline that wants N frames of it (a static intro card, a frozen last frame, a reference held constant across a clip). Multiply a single image by N and you've got your held shot.

It also matches frame counts between tracks. If your mask or latent stack is a multiple longer than your image batch, repeating the images to match is often exactly what an alignment step needs.

How it works

It concatenates the input onto itself multiply_by times along the frame axis. The output length is simply the input length times the multiplier - the node even hands you that number as a count output so you don't have to compute it. A multiplier of 1 (the default) is a pass-through: no change.

Inputs and outputs

• images (IMAGE) - the batch to repeat.
• multiply_by (INT, default 1, minimum 1) - how many total copies you end up with. 1 means unchanged; 2 doubles; 3 triples.

Outputs:

• IMAGE - the repeated batch.
• count (INT) - the new length (input length × multiply_by), useful for wiring into whatever consumes the result.

Installing it

On comfy.icu, VideoHelperSuite is already installed - the node's ready.

Locally: ComfyUI Manager → search ComfyUI-VideoHelperSuite → install → restart. Or:

cd ComfyUI/custom_nodes
git clone https://github.com/Kosinkadink/ComfyUI-VideoHelperSuite

then restart ComfyUI.

Common issues

Understand what "repeat" means here: it's the whole batch, appended. Multiply a 4-frame batch by 3 and you get 0,1,2,3,0,1,2,3,0,1,2,3 - twelve frames, three cycles. It does not interleave (0,0,0,1,1,1…). If you wanted each frame held in place rather than the sequence looped, this isn't that node.

Second, watch your memory. Repeating a big image batch multiplies the frame count for real, and everything downstream now processes that many frames - a 3× on a long, high-res clip is a genuine VRAM and time cost, not a free trick.

If the node doesn't show up at all, that's VideoHelperSuite failing to import (ffmpeg or a NumPy version clash); check the startup log and reinstall through Manager.
