Static reading of the pinned Kling 4.0 text-to-video template. One node set to 720p, 16:9, 10 s and seed 42 carries a 12,800-character prompt that times a single continuous shot in frames and seconds, and its output goes to SaveVideo. The file stores no frame rate. Nothing was run.

What this is: a reading of one workflow file from the official Comfy-Org workflow_templates repository, pinned at commit 0cc0fba5 (Kling 4.0: Text to Video, saved by ComfyUI frontend 1.57.1). Only the JSON was inspected. No workflow was run, no Kling API call was made and the example output was not opened, so nothing here describes an actual result.

Declared graph (2 nodes, 1 link): Kling4TextToVideoNode (node 1, no inputs) sends its VIDEO output to SaveVideo (node 2), prefix video/kling4_t2v, format mp4, codecs auto. There is no note node.

Stored settings on node 1 (positional and named copies agree): model kling-4.0, resolution 720p, aspect ratio 16:9, duration 10, seed 42. There is no audio or sound setting on the node. Two control_after_generate values are stored: the one right after the seed in the positional list (named control_after_generate#1) is randomize, and the last one (named control_after_generate) is fixed. The file does not say which of them governs the seed.

The prompt (about 12,800 characters) is a full direction document for one 10-second, single continuous shot of a miniature fantasy chase. Its structure:
- Top-priority motion rule: a dragonfly-style pattern of hovering, instant dash, complete hard stop and sharp change of direction, with at least six bursts in the first 7.8 seconds.
- Frame-level timing: each dash crosses 60-90% of the frame width within 3-5 frames and is followed by a 2-4 frame complete stop.
- Fixed character design, and a scene of a toy room with a block castle that opens into an underwater space.
- Camera rules: the camera lags each launch by 0.1-0.2 seconds, whips to catch up, may overshoot, and may briefly lose the character.
- A list of required speed evidence.
- A timeline in nine segments from 0-0.7 s to 9-10 s, ending in a still underwater frame ("do not fade to black").
- Closing negative rules: no hard cuts; no limb distortion, duplication, smoke, glowing trails, text, logos or watermarks.

Sound: the prompt contains no sound, music, dialogue or voice directions, and the node has no audio setting, so the template declares nothing about audio.

Reading notes: the prompt times motion in frames, but the workflow stores no frame rate, and the prompt itself names none, so the frame counts map to seconds only at whatever rate the service uses. The prompt is far longer than the other Kling 4.0 templates read in this set. It is written as a production spec rather than a description.

Not established: what the output looks like; whether any of the motion, camera or timing rules are followed; whether the length of the prompt is accepted in full; the effective frame rate; whether audio is produced; or the cost of a 10-second run. Kling service terms and the example output's terms are not covered.
