Correction, 2026-10-02: the page referred to TikTok's ad specs and gave the YouTube Shorts length without citing TikTok's or YouTube's own help pages; both are now checked and cited, along with Meta's Reels spec. It gave Veo 3.1 as 448 credits without saying that is Veo 3.1 Standard (the Veo tool opens on Veo 3.1 Fast, 168), and offered Wan 3.0 at 480p for "the cheapest drafts" without saying that a 480p vertical clip is under TikTok's 540 x 960 minimum. Three lines stated model behaviour as fact that we have not measured (hands slipping on contact, exact timings not landing, generated text changing shape); they are now things to check. The prompts were still written as text-only: each one now comes with the 9:16 start still Kling v3 needs, and the page states that Kling v3 Standard returns 720p. The closing line now uses our standard wording.
Correction, 2026-10-01: an earlier version said Kling v3 on 8frame makes 9:16 from text and presented these prompts as text-only. On 8frame, Kling v3 Standard and Pro are image-to-video only: they need a start image and follow its shape. The page now explains how to run each prompt from a 9:16 still, or as written on Kling 2.6 Pro (47 credits for 5 silent seconds, 95 with audio). The variant budgets also left out the start still Kling v3 needs; they now include it.
Kling v3 fits TikTok ad variant testing on price and format: on 8frame it animates a start image and keeps its shape (so a 9:16 still gives a 9:16 clip), runs 3 to 15 seconds, returns 720p, and costs 57 credits for 5 silent seconds or 86 with audio. It needs that image on 8frame; to run these prompts from text alone, use Kling 2.6 Pro (47 credits for 5 silent seconds, 95 with audio). These 8 prompts cover common TikTok ad formats, each with the start still to make first, plus a hook-first formula and what to check in each result.
Correction, 2026-09-30: the first version of this page presented these prompts as tested, with generation times, per-clip dollar costs and results of specific runs that we cannot reproduce. It also said Kling defaults to landscape unless "vertical 9:16" is in the prompt; on 8frame the shape is a node setting. The prompts and the formula stay; the test claims are gone.
TL;DR
- Start Kling v3 from a 9:16 still and set the length on the node. On 8frame, Kling v3 needs a start image and keeps its shape; writing "vertical 9:16, 5 seconds" in the prompt doesn't set either. For text only, use Kling 2.6 Pro with 9:16 set on the node.
- Describe frame zero. The hook is the opening of the clip; say what happens in the first second. On Kling v3, frame zero is your start image, so build the hook into the still.
- Add text in the edit. Ask for "no text overlay" in the prompt and set your copy in the editor, where you control the wording.
- Price on 8frame: Kling v3 Standard 57 credits for 5 seconds silent, 86 with audio, at 720p; Kling 2.6 Pro 47 silent, 95 with audio, at 1080p.
- TikTok's floor: vertical in-feed ads need 540 x 960 pixels or more. A 720p clip in 9:16 clears it; a 480p one does not.
When to use Kling v3 for TikTok ads
Use it when you're shipping volume: many hooks and products a week. Three silent 5-second variants cost 171 credits, plus the Nano Banana 2 start still at 1K: 11 if all three share one (182 in total, about $1.82 at pack rate), 33 if each hook gets its own (204). Kling v3 Standard returns 720p, which in 9:16 is above the 540 x 960 pixels TikTok asks for in vertical in-feed ads.
For a single 1080p shot with sound, Veo 3.1 Fast, the model the Veo tool opens on, is 168 credits for 8 seconds with audio, and Veo 3.1 Standard is 448. For low-cost drafts, Wan 3.0 is 24 credits for 5 seconds at 480p, but a 480p vertical clip is 480 pixels wide, under TikTok's 540, so regenerate the clip you ship at 720p (48 credits). The full list of TikTok's requirements is in TikTok ad video specs.
The prompt formula
Hook action at frame zero + subject and motion + camera behaviour + visual style + "no text overlay"
The hook action is the variable. It tells the model what's happening in the first frame. Without it, a clip may open on a static establishing shot, which is not what stops a scroll. Add "sound-on energy" if the clip will carry audio, or plan for captions if it must work with the sound off.
How to run these prompts on 8frame. Kling v3 animates a start image there, so each example below comes with a start still. Generate it first with Nano Banana 2 set to 9:16 on the node (11 credits at 1K), connect it to a Kling v3 node, and paste the Kling prompt, which tells the model the action and camera behaviour. To skip the still, run the Kling prompt as written on Kling 2.6 Pro with 9:16 set on the node.
8 prompts for TikTok ads
1. Pattern interrupt opener
Start still (Nano Banana 2, 9:16):
Extreme close-up of a glass of iced coffee in mid-air just above a white marble counter, a moment before impact. High contrast, saturated warm tones, commercial product photography. No text.
Kling v3 prompt:
A glass of iced coffee slams down onto a white marble counter in extreme close-up, liquid splashes up and hangs suspended for half a second, then falls. Camera holds tight on the glass. High contrast, saturated warm tones, kinetic energy, commercial product style. No text overlay.
The hook is a physical event at frame zero. Check that the first second reads on a phone before anything else.
2. Product reveal flip
Start still (Nano Banana 2, 9:16):
A matte black phone case lying face-down on a concrete surface, a hand entering from the right edge of the frame. Product photography lighting, slightly overexposed highlights, moody background. No text.
Kling v3 prompt:
A matte black phone case sits face-down on a concrete surface. A hand enters frame from the right, flips the case over to reveal a glowing logo on the back. Slow push-in begins as the flip completes. Product photography lighting, slightly overexposed highlights, moody background. No text overlay.
One hand, one object, one action. Check the logo when the case turns over; if it matters, keep the reveal slow.
3. Before-after split
Start still (Nano Banana 2, 9:16):
Split-screen of a kitchen sink in tight framing. Left half: a dry, cracked sponge on a grimy sink edge. Right half: the same sink clean and bright, a fresh sponge next to a bottle of cleaning product. Hard vertical split down the center. Studio lighting, clean commercial look. No text.
Kling v3 prompt:
Left half of frame: a dry, cracked kitchen sponge sitting on a grimy sink edge. Right half of frame: the same sink, clean and bright, a fresh sponge next to a bottle of cleaning product. Hard vertical split down the center. Camera slowly pulls back to reveal both halves in context. Studio lighting, commercial clean aesthetic. No text overlay.
A split frame asks the model to hold two states at once. Check both halves stay consistent through the pull-back.
4. Day-in-the-life quick cut
Start still (Nano Banana 2, 9:16):
First-person view of hands making coffee in a minimal kitchen. Warm morning light, neutral tones, aspirational lifestyle feel, no faces. No text.
Kling v3 prompt:
POV montage: 1) hands making coffee in a minimal kitchen, 2) laptop opening on a wood desk, 3) a protein shake being picked up from a counter. Each shot lasts about 1.5 seconds, quick cuts between them. Warm morning light, neutral tones, aspirational lifestyle feel, no faces shown. No text overlay.
Several shots inside one generation, and the start still only fixes the first. Check whether the cuts actually happen; if not, generate each shot from its own still and cut in the edit.
5. Direct-to-camera shock hook
Start still (Nano Banana 2, 9:16):
A woman in her late 20s looking directly into the camera with wide eyes, holding up a small skincare bottle. Natural bedroom lighting, raw smartphone UGC look, no professional styling. No text.
Kling v3 prompt:
A woman in her late 20s looks directly into camera, eyes wide, holds up a small skincare bottle, mouths the words "wait, this actually works?" in exaggerated disbelief. Handheld shaky cam, natural bedroom lighting, raw UGC look, no professional styling. No text overlay.
A raw UGC look with a face in close-up. Check the eyes and the hand holding the bottle, and decide whether you want the clip with or without audio.
6. POV first-person handling
Start still (Nano Banana 2, 9:16):
First-person view of hands holding a small perfume bottle near a window, label facing the camera, backlit golden-hour sunlight. No other text.
Kling v3 prompt:
First-person POV: hands holding a small perfume bottle, turning it over slowly, spraying once into the air. The mist catches backlit sunlight. The bottle label is clearly visible for at least 2 seconds. Minimal motion, deliberate pace, golden-hour window light, ASMR feel. No text overlay.
Label visibility is written into the prompt. Check the label while the bottle turns, and the mist against the backlight.
7. Speed ramp transition
Start still (Nano Banana 2, 9:16):
Low-angle close-up of a runner's feet striking wet asphalt, morning light, high contrast, sports commercial look. No text.
Kling v3 prompt:
A runner's feet hit pavement in slow motion, then the clip suddenly accelerates to 2x normal speed as they round a corner and sprint toward camera. Speed ramp at the 2.5-second mark. Sports energy, high contrast, morning light on wet asphalt. No text overlay.
A speed change inside one clip. If the ramp doesn't land where you want it, generate at one speed and ramp in the edit.
8. Caption-driven static shot
Start still (Nano Banana 2, 9:16):
A ceramic mug in the center of a wood table, a wisp of steam, soft diffused morning light from the left. Clean centered composition with empty space in the top and bottom thirds. Minimalist lifestyle look. No text.
Kling v3 prompt:
A ceramic mug sits in the center of a wood table, steam rising slowly. Camera holds completely still. Soft diffused morning light from the left. Clean composition, centered subject, room for text overlay at the top and bottom thirds. Minimalist lifestyle aesthetic. No text overlay.
The simplest shot: a static frame with room for captions. Check the top and bottom thirds stay clear for text.
Common problems and fixes
Vague hooks. "A product looks interesting" gives the model nothing for frame zero. Describe the physical event: what moves, what enters, what changes.
Hands and objects. Check hands that hold or touch things frame by frame. Keeping each shot to one hand, one action and one object leaves less to check.
Exact timing. Don't rely on a timestamp in the prompt such as "cut at exactly 2.3 seconds". Check where the change actually happens; if it's off, use pacing words and time the cut in the edit.
Text in frame. Ask for "no text overlay" and add copy in your editor.
Step-by-step on 8frame
- Open the 8frame canvas and add a Nano Banana node (it opens on Nano Banana 2 at 1K). Set 9:16 and generate the start still from the example's still prompt (11 credits).
- Add a Kling video node (it opens on Kling v3 Standard), connect the still as the start image (Kling v3 needs one on 8frame and keeps its shape), and set the length (3 to 15 seconds).
- Paste the Kling prompt, hook action first. Kling prompts can be up to 2,500 characters.
- Switch audio off and draft silent (57 credits for 5 seconds). If the hook reads, make two variants by changing one element.
- Add captions and audio in your editor, or generate the winner with audio (86).
No still? Switch the node to Kling 2.6 Pro, set 9:16 on the node and run the Kling prompt from text: 47 credits for 5 silent seconds, 95 with audio, at 5 or 10 seconds.
FAQ
Does Kling v3 support 9:16?
Yes, from a 9:16 start image: on 8frame, Kling v3 needs a start image and follows its shape, and Kling v3 Standard returns 720p. From text alone, Kling 2.6 Pro makes 9:16, 16:9 or 1:1; set it on the node.
Can I run these prompts without a start image?
Yes, on Kling 2.6 Pro: switch the Kling node to 2.6 Pro, set 9:16 and paste the Kling prompt as written. It costs 47 credits for 5 silent seconds and 95 with audio, at 5 or 10 seconds.
Is 720p enough for a TikTok ad?
In 9:16, yes: TikTok asks for 540 x 960 pixels or more for vertical in-feed ads, and a 720p vertical clip is wider than that. A 480p vertical clip is not.
How many variants should I run per hook?
Several: two generations from the same still and prompt can come out differently. Five silent 5-second variants of one hook on Kling v3 Standard cost 285 credits, plus 11 for the start still they share: 296, about $2.96 at pack rate.
Do these prompts work for Reels and YouTube Shorts?
Yes, both take vertical video. Meta's ad specs for Instagram Reels list 9:16, and YouTube counts square or vertical uploads of up to three minutes as Shorts; see YouTube Shorts length.
