Features
- 10-keyframe directing——Split 30 seconds into opening, beat and freeze frame; action plays out on a timeline so big dynamic moves do not fall apart.
- Native 30s one-take——A single pass generates 3 to 30 seconds with setup and payoff told in one go; extend past 30s by stitching up to 2 minutes.
- 15 refs, zero drift——Person, product and camera each get their own job across up to 15 reference assets, so swapped faces and melted products stay rare.
- Stereo + 4K——Two-channel ambience and dialogue arrive in the same pass, output up to 4K (HDR follows the official rollout).
How it works
- Upload one photo A selfie or a white-background product shot works; have nothing? Pure text generates from scratch.
- Pick a mode, one line Photo alive, text to film, remake a hit, or edit a clip. Use the formula: subject + action + scene + camera + lighting + sound.
- Take the MP4 with sound Coherent people, undeformed products. Draw extra takes and keep the best; aspect ratio follows the platform.
FAQ
- Is Kling 4.0 free?
- Short answer: sign in to Loomi and use it directly, no need to chase quotas on the Kling site. Steps: upload your material, pick a play mode, hit generate. Limits: queues run longer at peak hours, and 4K or 30s versions cost more credits — see the site rules.
- Can I start with one photo?
- Short answer: one photo is enough — that is the beginner bread and butter, like the bamboo look-back and the night-market dance. Steps: upload the first frame, pick Photo alive, describe one motion. More material (person plus product plus reference video) holds up better with fewer face swaps.
- How do I keep it realistic?
- Short answer: use the formula — subject plus action plus scene plus camera plus lighting plus sound, one main action per shot. Steps: short English phrases work best; always describe the sound (ambience, dialogue language, score mood). Limits: avoid sprinting, sharp turns and hand close-ups; split complex fights into two or three segments.
- Kling 4.0 vs Sora?
- Short answer: Kling wins on coherent human motion plus Chinese-language understanding plus vertical commercial output. Sora leads on long-lens narrative, Runway on controlled post-production. Rule of thumb: Douyin/TikTok sales and dialogue shorts go Kling 4.0; pure concept epics are worth trying everywhere.
- How to spot an AI video?
- Short answer: check three things — fingers, teeth and background text; whether walking slides or clips; whether a turn swaps the face. Steps: pause and scrub frame by frame, check official watermarks and version marks. Limits: Kling 4.0 holds up well on single frames, so judge the motion physics across frames.
- Where should a beginner start?
- Short answer: copy the bamboo look-back: upload one front-facing photo, pick Photo alive plus 5s plus vertical social, write one line of motion. Limits: do not open with a 30s epic — verify the face holds on a 5s test first, then go longer.
