Most video AIs blur on fast motion: hands melt and silhouettes warp. Kling 2.5 Pro locks body biomechanics and joint angles at any speed: dance, sports, jumps, and martial arts stay razor-sharp in 5-second (40 ₽ / 20 ₽ in LeinPremium) and 10-second (80 ₽ / 40 ₽ in LeinPremium) takes.
Acrobatic vault over a rooftop obstacle at dusk, smooth 360-degree mid-air torso rotation and crisp two-foot landing, dynamic tracking camera following the athlete, 10 seconds.
During fast turns, hands melt into jelly, legs merge, and facial identity drifts by second 4.
Rigid joint lock, natural fabric inertia, and preserved facial identity across all 5 or 10 seconds.
Trained on millions of hours of real physical movement, Kling preserves joint anatomy, fabric inertia, and facial features even in high-velocity scenes.
Kling 2.5 Pro excels at human biomechanics: joints, hands, and jump trajectories keep accurate geometry even during fast dance and sports.
Takes up to 10 seconds are twice as long as standard 5-second clips: enough for a complete choreography sequence, stunt, or action chase.
The official Chinese service requires a +86 SIM card and yuan payments. On LeinGPT, sign in within 10 seconds via Telegram or Yandex and pay in rubles.
Most video AIs cut off at 4-5 seconds. In Kling 2.5 Pro you choose between a punchy 5-second sprint and a complete 10-second continuous scene.
Open the LeinGPT Studio, select Kling 2.5 Pro, and choose your duration (5 or 10 seconds) and aspect ratio (16:9, 9:16, or 1:1).
Upload a starting photo as the first frame or describe your dynamic action scene, plus an optional Negative Prompt.
Download your finished video with crisp biomechanical motion for 40 ₽ (or 20 ₽ in LeinPremium).
No +86 SIM cards, Chinese menus, or 4-hour queues: launch Kling 2.5 Pro on the same balance as Runway, Gemini Omni, and Veo 3.1.

Choose Kling 2.5 Pro whenever the shot features intense human or vehicle motion: dance, martial arts, running, parkour, sports, and fast camera whips. For dialogue with native audio pick Veo 3.1, and for re-editing existing video pick Gemini Omni Flash.
The model is trained on spatiotemporal biomechanics: it calculates inertia, knee and shoulder angles, and preserves body volume across all 5 or 10 seconds.
5 seconds at 40 ₽ (20 ₽ in LeinPremium) is ideal for a punchy Reels shot or quick test. 10 seconds at 80 ₽ (40 ₽ in LeinPremium) lets you film a complete continuous scene without cuts.
Yes! Upload any photograph as the starting frame and describe the desired choreography. A Negative Prompt field (up to 2,500 characters) is also available.
Three core formats are supported: widescreen 16:9 for YouTube and music videos, vertical 9:16 for Reels, Shorts, and TikTok, and square 1:1.
No. On LeinGPT, Kling 2.5 Pro works directly without VPN or Chinese SMS codes, accepts natural-language prompts, and is billed per clip in rubles.
Launch 5-second sprints for 40 ₽ (20 ₽ in LeinPremium) and 10-second action scenes for 80 ₽ (40 ₽ in LeinPremium) without a +86 phone number or VPN.
