Shot Script Extractor JK🐉

Shot Script Combiner gives you all the shots; Shot Script Extractor gives you one. It plucks a single element out of a shot list - by position, or by key if you're working with a dict - and hands you the element, a count of how many elements there were, and a status string saying what it did. It's the node you reach for when a workflow needs shot 3 specifically, or when you want to re-generate just one shot instead of the whole sequence.

It's the more flexible of the two: where the Combiner forces everything into a list, the Extractor understands four input shapes and lets you pick which one you're feeding.

The inputs

• string_inputs - the shot script, in whatever form you have it.
• key_or_index (default "1") - a key name if the input is a dict, or a position if it's a list/array/multiline. Negative indexing works: -1 is the last shot, which is genuinely useful when you only want to regenerate the final shot of a sequence.
• input_type - tells the node what it's looking at: string_list, dict_string, array_string, or multilines. Dict strings get key-based lookup; everything else gets index-based.

The three outputs

• element (STRING) - the extracted shot prompt.
• element_counts (INT) - how many elements the input contained, handy as a sanity check or to drive a loop bound.
• status (STRING) - a human-readable note like Element 3 of 6 or Key 'subject' found. When something's wrong, this is where you'll see it, e.g. Key not found. Available keys: ... or Index out of range (1-6).

On out-of-range indexes in string-list mode it doesn't fail hard - it returns the last element and tells you so in status. Dict lookup tries an exact key match, then a case-insensitive one, then a numeric fallback, which covers the shot01 vs shot1 vs 1 mess that LLMs love to produce.

Install

In the JakeUpgrade pack:

cd ComfyUI/custom_nodes
git clone https://github.com/jakechai/ComfyUI-JakeUpgrade
cd ComfyUI-JakeUpgrade
pip install -r requirements.txt   # Windows standalone: install.bat

Or ComfyUI Manager → "JakeUpgrade". No models.

Where people get burned

The node is input-is-list, so if you wire it to a true list output it processes each entry - fine, but worth knowing before you wonder why status fires multiple times. And the index field is a string, not an int, because it doubles as a dict key; typing "3" works for a list, but a stray space will fail to parse and you'll get an "Invalid index" status. When in doubt, read the status output - it's the whole point of the node having it. If you're extracting just to re-feed one shot into an image sampler, pair it with a Shot Script Combiner output and you can move shots around a graph without ever copying text by hand.
