Built for 4K, end to end
Six things Seedance 2.0 4K does that 720p models can't fake — the proof reel is above, the side-by-sides below.
Native 4K resolution
True 2160p — 4× the pixels of 1080p, crisp to the edge.
Detail held across motion
Skin, fabric, water and reflections stay sharp as the camera moves.
Native synced audio
Dialogue, SFX & music generated with the shot — lip-synced.
One master, many crops
Reframe a 4K master to 9:16, 1:1 or 21:9 — still sharp.
Big-screen & broadcast
Resolution & range built for TV, cinema and OOH displays.
Multi-shot sequences
Several shots with natural cuts in one clip — consistent.
Prompt → 4K, every time
Copy a prompt, hit generate. Each example is the exact text that made the clip — great for learning the model.
“Jazz singer at a vintage mic delivers a line, lip-synced, warm club light — 4K with native audio.”The exact prompt — generated on Seedance 2.0 4K“Drone over a red-rock canyon river, sunrise haze, speed-ramp into the bend, 4K — reframes to 9:16 + 1:1.”The exact prompt — generated on Seedance 2.0 4KWhere 4K earns its keep
Use 4K for finals that play big or get cropped — drafts can stay 720p.
Film & previz
Hero shots & establishing plates, edit-ready.
Product & e-comm
Material detail, then crop per channel.
Premium social
4K feeds & YouTube — a quality signal.
Watch the seam
Same frame, split down the middle: native Seedance 2.0 4K on the left, a standard upscale on the right. Detail either lives in the pixels — or it doesn't.

Seedance 2.0 4K FAQ
Native. Seedance 2.0 renders at up to 2160p from the start on Popcraft — it is not a 1080p clip upscaled afterward, so detail holds under motion and reframing.
Yes — dialogue with lip-sync, sound effects and music are generated alongside the video, so the 4K clip arrives finished without a separate audio pass.
4 to 15 seconds, with multiple shots and natural cuts inside a single clip. Stitch clips on the Popcraft timeline for longer pieces.
16:9, 9:16, 1:1, 4:3, 3:4 and 21:9. A 4K master has enough pixels to crop into vertical or square and still export sharp.
For finals on large or close-viewed screens (TV, cinema, OOH, 4K social) or when you'll crop a master. Draft at 720p or 1080p — it's faster and cheaper.
Pricing is credit-based, and 4K uses more credits than 1080p because it renders four times the pixels. Free accounts include credits to start; paid plans and top-ups extend your budget.
