Assessment
Strengths and limitations
- Full 4K output across the whole clip length: up to 30 seconds in one take, no stitching or upscaling.
- Native audio in 4K clips: dialogue with lip sync, music and ambient sound, generated with the picture.
- 30 seconds in 4K: twice the 15 seconds of Kling O3 4K and Kling V3 4K, and nearly four times Veo 3.1's 8.
- All three modes render in 4K: text-to-video, image-to-video and reference-to-video.
- Reference control at 4K: keep characters and products consistent from up to 30 reference images.
- 4K costs about 1.6x the 1080p price per clip; draft at 480p or 720p and render the final in 4K.
- Not open source: it cannot be self-hosted or fine-tuned.
- Anonymous, not private: ByteDance still receives the content you send, and there is no TEE or end-to-end encryption.
Use cases
What it is good for
- 014K ad spots up to 30 seconds, with lip-synced dialogue and consistent products.
- 02Footage for large screens: billboards, LED walls, cinema pre-roll and projection.
- 03Hero shots you can crop, reframe or stabilize in the edit without losing detail.
- 04Animating 4K product stills and key art with image-to-video.
- 05Finishing a sequence you drafted at 480p, rendered again as the 4K master.
Prompting
Getting better results
Draft the take at 480p or 720p, then render the one you pick in 4K with the same prompt.
4K rewards texture: name fabrics, skin, materials, weather and light in the prompt.
For image-to-video, start from a sharp, high-resolution image so 4K has detail to keep.
Put dialogue in quotes to get lip-synced speech.
Use reference images of characters or products to keep them consistent across the clip.
Write scene changes as numbered shots to guide continuity over 30 seconds.
Samples
Sample outputs
Generated on Venice with our standard prompt suite — the same prompts we run through every model of this type, so you can judge it like-for-like.
Slow aerial drone shot gliding over a misty mountain valley at golden hour, sunlight piercing clouds onto a winding river, ancient pine forests on either side, ultra-smooth motion, professional color grading, atmospheric haze, 4K
Calm ocean waves rolling onto a black-sand beach at sunrise, golden light on wet sand, foam dissolving into the shore, a single silhouetted figure at the waterline, smooth continuous forward push, serene cinematic atmosphere
A slow tracking shot through a rain-soaked Tokyo street at night, neon reflecting in puddles, steam rising from a food cart, a person with a translucent umbrella, shallow depth of field, teal-and-orange grade, smooth steady camera
