⌨️ CR Load Animation Frames

Before ComfyUI had solid native video/batch-image loading, if you wanted to pull a folder of numbered frames in as a batch for animation work, you needed a node built for exactly that. CR Load Animation Frames does the basic version: point it at a folder, tell it where to start and how many frames to grab, and it hands you back an IMAGE batch.

How it works

image_sequence_folder is a dropdown populated from folders ComfyUI can already see (typically under your input directory) - you pick the folder holding your numbered frame sequence rather than typing a path. start_index tells it which frame number to begin at, and max_frames caps how many it loads from there. The result comes out as a single IMAGE output - a batch, not a list - so downstream nodes that expect a normal image batch (a batch VAE encode, a batch-aware sampler, a save with numbered filenames) work with it directly.

This is a straightforward building block for anything that processes a pre-rendered frame sequence: frame-by-frame stylization, batch-upscaling a rendered animation, or feeding frames into a template that expects an image batch as its source.

Inputs and outputs that matter

• image_sequence_folder - pick the folder of frames.
• start_index - where in the sequence to begin (1–10000).
• max_frames - how many frames to pull from that starting point (1–10000).
• Output is IMAGE (the loaded batch) plus show_help.

How to install it

ComfyUI Manager: search "Comfyroll Studio", install, restart. Manual: cd ComfyUI/custom_nodes && git clone https://github.com/Suzie1/ComfyUI_Comfyroll_CustomNodes.git, restart. No model weights involved - it's a file loader.

Common issues

The image_sequence_folder dropdown only lists folders ComfyUI already knows about - if your frames aren't showing up as an option, they're probably not sitting under the input directory ComfyUI is watching. Move them there and restart (or refresh) before the folder appears.

Loading max_frames frames at once means all of them sit in memory/VRAM together once you push the batch into a sampler - a few hundred high-resolution frames adds up fast. If you're working through a long sequence, load it in chunks (bump start_index and re-run) rather than trying to pull everything in one pass.

As with every node in this pack: if it's not in the search menu at all, that's most likely Comfyroll's shared registration file failing somewhere else in the pack, not this node specifically. Check the ComfyUI startup console for an import error and reinstall cleanly if you see one.
