Kling 3.0 Video

The Kling Video node - display name "Kling 3.0 Video" - is the current flagship of the Kling family in ComfyUI, and the one you should probably learn first if you're starting fresh in 2026. It replaces the patchwork of old Kling nodes with a single node that does text-to-video, image-to-video, multi-shot storyboards, and (on one model) native audio. It landed with the Kling 3.0 rollout, so this is the modern path rather than the legacy line.

Mechanically it's the standard partner-node pattern with extra polish: the node submits a generation to Kling's servers through your Comfy account, polls until the task completes, and hands back a VIDEO. Nothing runs locally, no model files, and the node carries a live price badge that recomputes from your model, resolution, audio toggle, and every storyboard duration - so you can watch the credit burn before you commit.

The inputs that matter:

• model - a dynamic combo with two options. kling-v3 gives you 720p/1080p/4k; kling-3.0-turbo caps at 720p/1080p but always generates native audio (see the gotcha below).
• multi_shot - the storyboard switch. Leave it "disabled" and you get a simple prompt + negative_prompt + duration (3–15s). Flip to "1 storyboard" through "6 storyboards" and the node expands per-segment prompt and duration fields so you can generate a full sequence in one call.
• generate_audio - on by default. On the turbo model this toggle is ignored, because turbo always ships native audio. On kling-v3 it genuinely controls whether you pay for generated sound.
• seed - the standard Kling stub: it only decides whether the node re-runs; results are non-deterministic either way.
• start_frame - optional IMAGE. Connect one and the node switches to image-to-video mode automatically; the aspect_ratio setting is then ignored.

Single VIDEO output, into Save Video or Preview Video.

The traps are mostly feature surprises. The audio toggle doing nothing on turbo trips people up constantly - it's not a bug, turbo is audio-always. Similarly, in image-to-video mode the aspect ratio is ignored because the frame defines it, and if you leave it set to something tall while your image is wide, nothing breaks but the widget lies to you. And with multi-shot, remember you're billed on the sum of storyboard durations - the price badge is your friend here.

House rules for the whole family: you must be logged into your Comfy account or the node refuses to run, and if partner nodes clutter your search, --disable-api-nodes in the launch args hides them all.
