Correction, 2026-10-02: the page 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 so said Veo costs about three times Kling v3 per second; Veo 3.1 Fast is 21 credits a second with audio against about 17 for Kling v3 Standard. It did not say that Kling v3 Standard returns 720p, under the 1440 x 2560 Meta recommends for Reels ads, and it referred to Meta's specs without citing Meta; Meta's ads guide is now cited, with its safe zone. Several lines stated behaviour we have not measured (that the negatives rule out common failures, that several shorter clips are usually safer than one long take, that multi-scene shots are hard, that reference images hold a product through the clip); 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. 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 per-shot prices also left out the start still Kling v3 needs; they now include it.
Kling v3 fits Instagram Reels on format and price: 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 Reels formats: slow aesthetic moments, product reveals, behind-the-scenes craft, lifestyle shots, transformations, quick tips, music-led beats and multi-scene sequences, each with the start still to make first and what to check in the result.
Correction, 2026-09-30: the first version of this page presented these prompts as run in June 2026, with generation times, run-by-run results and a statistic about Kling outputs we cannot reproduce, made unsourced claims about Reels audiences, and said Kling costs a fraction of Wan (Wan 3.0 is cheaper: 24 credits for 5 seconds at 480p). The prompts and the formula stay; the rest is 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" in the prompt doesn't set it. For text only, use Kling 2.6 Pro with 9:16 set on the node.
- End prompts with negatives: "no camera shake, no text overlay". Then check the result for each.
- Keep the safe zone clear. Meta suggests leaving at least 14% at the top, 35% at the bottom and 6% on each side free of text, logos and other important elements, so compose the start still with the subject in the middle.
- Price on 8frame: Kling v3 Standard 57 credits for 5 seconds silent, 86 with audio ($0.57 and $0.86 at pack rate), at 720p, plus 11 for the Nano Banana 2 start still at 1K, which every variant of a shot can share.
- Meta's numbers: 9:16, with 1440 x 2560 recommended. A 720p vertical clip is 720 pixels wide: above Meta's 250-pixel minimum width for ads under 30 seconds, under the recommended size.
When to use Kling v3 for Instagram Reels
Kling v3 fits one-scene, aesthetic-led Reels where you want several variants: three silent 5-second variants from one shared start still cost 171 + 11 = 182 credits, about $1.82 at pack rate.
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 (the Wan tool opens at 1080p, so switch it). If the clip should start from several reference images of a product rather than one still, Seedance 2.5 takes up to 9 on the canvas and Kling O1 Reference up to 7; check that the product stays the same through the clip. Meta's full Reels ad specs are in Instagram Reels ad specs.
The Reels specs that shape the prompt
Meta's ads guide lists these for Instagram Reels video ads: ratio 9:16; a resolution of 1440 x 2560 pixels among its design recommendations; a minimum width of 250 pixels for ads under 30 seconds and 500 pixels for 30 seconds or longer; MP4 or MOV, up to 4 GB, 0 seconds to 15 minutes. It suggests leaving at least 14% of the top, 35% of the bottom and 6% on each side free of text, logos or other important creative elements.
Two consequences for these prompts. Compose the start still with the subject and any product detail in the middle band, clear of the bottom 35%, which is why the still prompts below ask for space at the top and bottom. And keep "no text overlay" in the prompt: add captions in your editor, where you can place them inside the safe zone.
The prompt formula
Every Kling v3 Reels prompt follows this structure:
[Subject] + [Action or state] + [Setting and light] + [Camera move] + [Technical spec] + [Negatives]
The negatives name common ways an aesthetic brief goes wrong: "no camera shake, no text overlay, no jump cuts, no grain". They are requests, not guarantees, so check the result for each one. Set the length on the node, not in the prompt; the 9:16 shape comes from the start image on Kling v3, or from the node setting on Kling 2.6 Pro.
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 motion and the camera move. To skip the still, run the Kling prompt as written on Kling 2.6 Pro with 9:16 set on the node.
8 Kling v3 prompts for Instagram Reels
1. Aesthetic moment (mood-led, slow pan)
Start still (Nano Banana 2, 9:16):
Overhead view of a sunlit linen tablecloth with a single espresso cup and scattered dried flowers. Morning light, soft shadows, no people. Cinematic, shallow depth of field. Cup in the middle of the frame, empty space at the top and bottom. No text.
Kling v3 prompt:
Aerial slow pan over a sunlit linen tablecloth with a single espresso cup and scattered dried flowers. Morning light, soft shadows, no people. Cinematic, shallow depth of field. No camera shake, no text overlay, no grain.
What to check: The linen texture through the move, and whether the pan is as slow as you want. If not, describe the speed more concretely.
2. Product reveal aesthetic
Start still (Nano Banana 2, 9:16):
A glass perfume bottle on a wet marble surface, water droplets beaded on the stone, a little mist at its base. Close-up macro, golden hour light. Bottle in the middle of the frame, empty space at the top and bottom. No text.
Kling v3 prompt:
A glass perfume bottle sitting on a wet marble surface. Water droplets bead and run across the stone. The bottle catches the light slowly as mist rises around it. Close-up macro, golden hour. No camera shake, no text overlay, no reflections of crew.
What to check: Droplet behaviour on the marble and whether the mist reads as mist. Check the bottle for reflections you didn't ask for.
3. Behind-the-scenes craft
Start still (Nano Banana 2, 9:16):
Hands resting on wet, warm-toned clay on a potter's wheel in a workshop. Warm overhead light with soft shadows. Hands and clay in the middle of the frame. No modern elements visible. No text.
Kling v3 prompt:
Close-up of hands shaping clay on a potter's wheel. The clay spins slowly, wet and warm-toned under workshop lighting. Medium shot, warm overhead light with soft shadows. No camera shake, no text overlay, no modern elements visible.
What to check: Hand anatomy through the whole clip, especially fingers in contact with the clay, and the clay's shape under motion.
4. Lifestyle vignette
Start still (Nano Banana 2, 9:16):
A woman in a cream linen outfit reading a book on a sunlit balcony. Mediterranean setting, white stucco walls, potted olive tree in the background. Medium shot, subject in the middle of the frame. No phone or screen visible. No text.
Kling v3 prompt:
A woman in a cream linen outfit reads a book on a sunlit balcony. Light breeze moves her hair and the pages slightly. Mediterranean setting, white stucco walls, potted olive tree in background. Medium shot. No camera shake, no text overlay, no phone or screen visible.
What to check: Hair and fabric moving with the same breeze as the background tree, and the book staying a book rather than a blur of paper.
5. Transformation timelapse
Start still (Nano Banana 2, 9:16):
A bouquet of white peonies as tight, closed buds in a clear glass vase. Clean white background, soft studio lighting, centered composition with empty space at the top and bottom. No text.
Kling v3 prompt:
A time lapse of a bouquet of white peonies blooming from tight buds to full open flowers. Clean white background, soft studio lighting, locked camera. No camera shake, no shadows changing unnaturally, no text overlay.
What to check: That the bloom goes through clear stages without jumps, and the white background stays white.
6. Educational quick-tip visual
Start still (Nano Banana 2, 9:16):
A split-frame image: on the left, a cluttered desk with poor lighting; on the right, the same desk organized and lit with warm side light. Clean, modern aesthetic. No people visible. No text.
Kling v3 prompt:
A split-frame visual: on the left, a cluttered desk with poor lighting; on the right, the same desk organized and lit with warm side light. Camera slowly pulls back to show both sides simultaneously. Clean, modern aesthetic. No text overlay, no camera shake, no people visible.
What to check: That the split frame holds for the whole clip and the two sides read as clearly different. For sharper contrast, say so before the negatives.
7. Music-led visual moment
Start still (Nano Banana 2, 9:16):
Close-up of a vinyl record on a turntable under warm amber stage light, bokeh background. Clean record surface, no scratches. Record in the middle of the frame. No text.
Kling v3 prompt:
Slow motion close-up of a vinyl record spinning under warm colored stage light. The light pulses and shifts between amber and deep violet as if reacting to a beat. Bokeh background, slow motion. No camera shake, no text overlay, no scratch or damage on record.
What to check: That the light shift is smooth rather than strobing, and the record surface reflects it. Generate a little longer than you need so you can pick the best window in the edit.
8. Carousel-style multi-scene
Start still (Nano Banana 2, 9:16):
A flat lay of skincare products on white marble, warm bathroom lighting, no visible logos on the products. Products in the middle of the frame. No text.
Kling v3 prompt:
A sequence of three connected vignettes in one continuous shot: first, a flat lay of skincare products on white marble; then the camera slowly rises to a woman applying serum; then it pulls back to show her at a vanity mirror. Smooth transitions, warm bathroom lighting. No camera shake, no text overlay, no visible logos on products.
What to check: Each transition between the three scenes; the start still only fixes the first one. If a transition jumps, generate each scene from its own still and cut them together in the edit.
Common failures
Three patterns to avoid:
Over-prompting the camera move. "Slow pan left while also pulling back and rotating 10 degrees counterclockwise" asks for competing moves. Pick one.
Missing the negatives. Without "no camera shake" and "no text overlay", you leave room for a handheld wobble or stray text in the scene (signs, labels), which can pull focus or cause problems on commercial work.
Unchecked long takes. Kling v3 runs up to 15 seconds. On a long clip, check the end as carefully as the start for changes in lighting, background or subject position; if it drifts, cut several shorter clips together instead.
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) and connect the still as the start image (Kling v3 needs one on 8frame and keeps its 9:16 shape). Don't rely on the prompt text for the shape.
- Paste the Kling prompt, following the formula: subject, action, setting, camera move, technical spec, negatives. Kling prompts can be up to 2,500 characters.
- Set the length (3 to 15 seconds); 5 to 8 is a good range for single-scene shots.
- Switch audio off and draft silent (57 credits for 5 seconds, on top of 11 for the still from step 1). Review before running variants; they can reuse the same still.
- Add sound by generating the winner with audio (86 credits for 5 seconds) or in the edit, and place captions inside the safe zone.
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
What aspect ratio should I use for Instagram Reels with Kling v3?
9:16, the ratio Meta lists for Reels ads. Writing it in the prompt doesn't set the shape. On 8frame, Kling v3 needs a start image and follows its shape, so start from a 9:16 image; for text-only prompts on Kling 2.6 Pro, set 9:16 on the node.
Is 720p enough for a Reels ad?
It meets Meta's minimum: a 720p vertical clip is 720 pixels wide, and Meta's minimum width is 250 pixels for ads under 30 seconds. It is under the 1440 x 2560 Meta recommends. Kling 2.6 Pro returns 1080p, also under that figure.
Where should text go in a Reels clip?
Inside the safe zone: Meta suggests keeping at least 14% at the top, 35% at the bottom and 6% on each side free of text, logos and other important elements. Ask Kling for "no text overlay" and add your copy in the editor.
How long should my Kling prompt be for Instagram Reels?
Long enough to cover subject, action, setting, one camera move and the negatives; short enough that instructions don't compete. Kling accepts up to 2,500 characters, but most of these prompts are a few sentences.
Is Kling v3 better than Veo 3.1 for Reels?
We have not compared their output. On price, Veo 3.1 Fast, the model the Veo tool opens on, is 168 credits for 8 seconds with audio (21 a second) at 1080p; Veo 3.1 Standard is 448 (56 a second); Kling v3 Standard is 86 for 5 seconds with audio (about 17 a second) at 720p. Run your shot on both and compare. See how to make a UGC ad with AI.
