Examples

Cinematic scene

Create a 30-second, 1080p, 16:9 ultra-realistic live-action home video in an older Seoul neighborhood on a warm late-summer afternoon. MAIN WOMAN Use the uploaded reference for her exact facial identity. Adult Korean woman, early 20s, natural beauty, realistic skin, minimal makeup. Long loose dark-brown wavy hair, tucked behind one ear, small black hair clip. Outfit: butter-yellow relaxed short-sleeve blouse, high-waisted washed charcoal jeans, white sneakers, forest-green shoulder bag, delicate gold necklace and tiny gold earrings. Keep identical throughout. FRUIT VENDOR & STALL Realistic middle-aged Korean male vendor, short dark hair, light-gray T-shirt, dark-red apron, transparent gloves, wristwatch. One single consistent roadside fruit stall throughout: glass display, metal frame, canopy, stainless counter, white cutting board, large cleaver, scale, trays, transparent bags and rubber bands. Inside: prepared pineapple, watermelon, mango, papaya, cantaloupe and dragon fruit. Pineapple is already peeled. Never show peeling. STORY 00:00–00:05: Woman walks through the neighborhood, notices the fruit stall, approaches and points at the pineapple. Woman: “Pineapple, please.” 00:05–00:10: Vendor takes the already-peeled pineapple from the same display tray and places it on the cutting board. 00:10–00:16: He realistically cuts the pineapple into bite-sized pieces with controlled cleaver movements. Natural juice and fruit texture. Woman: “That looks really fresh.” 00:16–00:22: Vendor puts the pieces into a transparent bag and closes it with a rubber band. Woman takes money from her green bag. 00:22–00:26: She pays and receives the same bag. Woman: “Thank you.” 00:26–00:30: She walks away, tastes one piece, smiles genuinely and looks toward camera. Woman: “Okay… that’s good.” She continues down the sunny alley. The same stall and vendor remain visible. A scooter passes in the distance. Brief autofocus shift, then hard cut to black. VISUAL STYLE Raw early-2000s consumer DV home-video look: handheld camera, natural shake, imperfect framing, autofocus hunting, mild exposure shifts, soft digital detail, slight motion blur, warm faded colors and occasional tiny zoom. No cinematic/commercial look or stabilization. AUDIO Natural Seoul ambience only: footsteps, scooters, bicycles, birds, distant conversations, traffic, glass, cutting sounds, plastic bag and rubber band sounds, natural dialogue and camera handling. No music, narration, subtitles, captions, translations, logos, watermarks or random text. REALISM LOCK Maintain identical woman, vendor, clothing, stall, fruit arrangement, tools and environment throughout. Realistic hands, anatomy, knife physics, fruit texture, glass reflections, bag movement and facial expressions. No duplicated/disappearing objects, changing stall design, extra vendors, distorted hands or CGI appearance. Final feel: An ordinary, imperfectly captured Seoul street-food moment—not a polished commercial.

Visual transformation

Cinematic scene

Cinematic scene

Cinematic scene

15 seconds, 16:9 horizontal, one continuous static take. SUBJECT: An exceptionally beautiful, sexy blonde fitness influencer in her mid-20s. Striking feminine photogenic face, expressive eyes, full lips, lightly tanned skin, long thick blonde hair in a high ponytail, slim feminine athletic hourglass figure. Black fitted gym tank and fitted workout leggings. She has just finished a hard workout: flushed cheeks, visible sweat, slightly damp hair and realistic skin texture. She must remain gorgeous, sexy and photogenic throughout. CAMERA: Recorded on an older camera, standard 1x lens. The camera is mounted horizontally in landscape orientation on a small tabletop tripod standing on the sink counter directly in front of a large wall mirror. The camera points straight at the mirror. The camera itself is the only camera recording the scene. There is no external or third-person camera. The viewer sees the woman primarily through her reflection in the mirror. The reflection of the horizontally mounted camera and small tripod is clearly visible near the bottom-center of the mirror, making the recording setup immediately understandable. COMPOSITION: Large mirror fills most of the frame. Sink and counter are visible along the bottom. In the mirror background, directly behind the recording camera, a bathroom entrance door is clearly visible with a simple recognizable female restroom pictogram. No written restroom text. The woman enters through this exact door and walks toward the sink, so the geography remains physically consistent. LOOK: Raw low-quality camera footage. Heavy compression and sensor noise, slight softness, harsh cool-green fluorescent gym-bathroom lighting, mild auto-exposure fluctuations and realistic bathroom reflections. The CAMERA QUALITY is rough; the WOMAN remains exceptionally beautiful and sexy. No cinematic grading or polished commercial look. AUDIO: Bathroom echo, heavy breathing, running tap, water splashes and paper towel sounds. No music. ACTION: 1. 0–3s: In the mirror background, the women’s restroom door opens. She enters visibly breathless after training, walks toward the sink and looks at her reflection. 2. 3–7s: Standing at the sink, she turns on the tap and splashes cold water over her face. She gasps softly and exhales. 3. 7–11s: She grips the edge of the sink, catches her breath and stares at herself in the mirror. Water runs down her face. She pushes her damp blonde hair back. 4. 11–15s: Still looking at her reflection, she says quietly and breathlessly: “one more set… then I’m done.” She grabs a paper towel, pats her face and starts to turn back toward the door. IMPORTANT: One uninterrupted static 15-second shot. Camera remains horizontally mounted on the tripod for the entire video. Its reflection stays visible in the mirror. The women’s restroom door and female pictogram remain clearly identifiable in the mirror background. Same woman, face, body, outfit and hairstyle throughout. No cuts, no angle changes, no handheld camera, no invisible camera, no extra people, no scene skipping, no broken mirror geometry, no disappearing camera/tripod, no readable text.

Cinematic scene

Create a 30-second, 1080p, 16:9 ultra-realistic live-action home video of a naturally beautiful adult Korean woman in her early 20s spending a warm late-summer afternoon with her friend in an older Seoul neighborhood. The video should feel like a genuine early-2000s consumer DV recording—not a commercial, music video, or staged production. Keep everything simple, attractive, spontaneous, and believable. MAIN SUBJECT & CONTINUITY Long dark-brown hair worn down with a soft natural wave, minimal makeup, realistic skin texture, relaxed expressions. She wears a fitted white short-sleeve top, light-blue straight-leg jeans, white sneakers, a small dark-brown shoulder bag, and a delicate silver necklace. Keep her face, hairstyle, outfit, accessories, body proportions, and the same bottled drink perfectly consistent throughout. LOCATION A quiet older Seoul residential neighborhood: narrow concrete streets, small apartment buildings, brick walls, potted plants, parked bicycles, utility poles, overhead wires, a tiny convenience shop, and shaded walkways. No landmarks, recognizable brands, advertisements, or commercial activity. VISUAL STYLE Authentic handheld DV footage with natural camera shake, imperfect framing, autofocus breathing, occasional exposure changes, soft digital detail, faded colors, mild video noise, natural motion blur, and occasional accidental zooms. The friend filming should react naturally. No stabilization, drone shots, gimbal movement, slow motion, beauty filters, or polished cinematic look. STORY — 30 SECONDS - 00:00–00:05: She leaves her apartment, adjusts her bag, notices the camera, and smiles. Her friend follows casually. - 00:05–00:10: She buys a cold bottled drink, presses it against her cheek, laughs at a camera zoom, and says, “It's so hot today.” - 00:10–00:15: They walk down a quieter street. A bicycle passes, she steps aside, then smiles back at the camera as a breeze moves her hair. - 00:15–00:20: She sits on a low wall beside an apartment garden. Her friend points out a tiny leaf in her hair. She removes it and laughs. - 00:20–00:25: They walk again. She briefly takes the drink from her friend, takes a sip, gives it back, and smiles toward the camera. - 00:25–00:30: At her apartment entrance, she waves and says, “See you tomorrow.” She walks inside. The friend keeps filming for one second as the door closes, then the footage abruptly cuts to black. AUDIO Natural location audio only: footsteps, distant traffic, bicycles, summer insects, apartment ambience, shop refrigerator hum, bottle movement, leaves, and quiet neighborhood voices. Natural dialogue only. No music, narration, artificial sound effects, subtitles, captions, logos, watermarks, or random text. REALISM Natural walking, sitting, drinking, hair movement, and hand gestures. No exaggerated acting, identity drift, outfit changes, distorted hands, extra fingers, duplicated people, teleportation, CGI appearance, or impossible physics. FINAL FEEL Simple, pretty, and real. Like a random personal video discovered years later nothing dramatic happened, but it somehow feels like a real memory.

At a glance

Is this model right for you?

This image-to-video workflow always uses a first image and may use image 2 as the last frame. Controls cover only duration, negative prompt, and CFG; there is no text-only, aspect-ratio, or audio control.

What it does best
Pro corresponds to Kling AI 2.1's High Quality (1080p) tier; Kyeo exposes it as a fixed image-to-video workflow with a required first image and an optional last image.
Who it is for
It fits product transitions, character movement, poster-to-end-card drafts, and storyboard links where both the starting composition and desired ending already exist.
Why use it on Kyeo AI
Kyeo writes image 1 to starting image and image 2 to ending-frame image, then shows the 5- and 10-second credit tiers for repeatable tests with fixed assets.

Decision guide

Still deciding? Start with these key decision points.

1
Choose it for a designed start and end

Compare Pro when you have 1 first image and an optional last image and need a 1080p transition lasting 5 or 10 seconds.

2
Compare another workflow when needed

Compare Standard for a 720p single-image test or Master for text and image routes in one model.

3
Start with one controlled test

Fix the first image, last image, prompt, negative prompt, and CFG for a 5-second run; change one variable at a time and record whether the ending moves closer to the last image.

Real-world experience

Practical guidance based on public sources, current on-site limits, and representative tasks.

Choose by workflow boundaries first

Kyeo's Pro integration only accepts image-to-video work. Text-only, audio, or aspect-ratio requirements should rule it out rather than borrowing features from other Kling versions.

A resolution tier is not a measured result

Kuaishou labels High Quality as 1080p. That establishes the official tier, not real-world image quality, motion, last-frame adherence, speed, or stability for a specific asset.

Capabilities

Fixed first-last-frame image workflow

Does Kling V2.1 Pro support text-to-video? — It fits product transitions, character movement, poster-to-end-card drafts, and storyboard links where both the starting composition and desired ending already exist.

Current parameter boundaries are documented

`prompt` allows up to 5,000 characters, `negative_prompt` up to 500, and `cfg_scale` runs from 0 to 1 in 0.1 steps; `duration` is limited to 5 or 10 seconds.

First and last image formats differ

Kling V2.1 Pro CFG range — 5,000 characters

Use cases

Product start-to-end transitions

Test a turn, opening action, or scene change with approved product images; review packaging, trademarks, text, and product geometry frame by frame.

Character movement to a final pose

Use start and end images of the same character to test action and camera paths, then check identity, clothing, anatomy, and pose continuity.

Poster-to-end-card draft

Turn compatible poster and end-card compositions into a 5-second transition draft; it cannot guarantee accurate text or final production quality.

Prompt tips

Make the first and last images compatible

Keep subject identity, perspective, framing, and scene structure compatible, with plausible space for the intended movement.

Describe only the change between them

State the subject movement, camera motion, order, and speed without repeating static details already visible in the images.

Test one variable at a time

Keep both images and the main prompt fixed, then adjust duration, negative prompt, or CFG separately so each difference has a traceable cause.

Why choose it

Optional image 2 maps directly to ending-frame image, giving the ending a defined input field.
The 5- and 10-second tiers cost 50 and 100 credits, so the Kyeo budget is explicit.
Kling V2.1 Pro input limit — It fits product transitions, character movement, poster-to-end-card drafts, and storyboard links where both the starting composition and desired ending already exist.
Kuaishou officially defines High Quality as the 1080p tier, so resolution does not need to be inferred from the Pro name.

What to know first

Kyeo's current route is image-to-video only and cannot generate from text alone.
The first image is required. The optional last image can guide the ending, but it does not lock the result pixel for pixel.
There is no aspect ratio, audio, or safety-check switch; the input workflow determines framing, and people must still review safety.
If you already need to compare text and image generation, Master or V2.5 Turbo Pro is the more direct choice.
