Real faces, flexible runtime, built-in audio
Upload a real face and keep it on screen
Seedance 2 is the model on ClipTrend.ai that still accepts a real-face reference upload — most competitors quietly turned this off. Drop in a photo of a real person and Seedance 2 carries that identity through the whole clip with omni reference, so the face you uploaded is the face that moves, talks and reacts on screen.
- ✓Open, not blocked — real-face reference stays on while other tools removed it
- ✓Omni reference — guide a shot with a face photo, a still, a video clip or audio
- ✓Identity holds — the uploaded person stays consistent for the full 4–15s
Pick any length from 4 to 15 seconds
Most models lock you to 5 or 10 seconds. Seedance 2 lets you set any length from 4 to 15 seconds in one-second steps, so a 7-second hook or a 13-second walkthrough comes out at exactly the runtime you need — no looping, no hard cut to pad a slot.
- ✓12 length steps — 4, 5, 6 … all the way to 15 seconds
- ✓No re-render — hit the exact runtime your edit needs the first time
- ✓Up to 1080p — 480p for drafts, 1080p for the final upload
Sound and the right frame, baked in
Seedance 2 generates a matching soundtrack and effects with the video — no separate audio pass — and renders in six aspect ratios including the wide 21:9 cinematic frame. One generation gives you a finished, watermark-free MP4 sized for Reels, Shorts, feed or a widescreen edit.
- ✓Built-in audio — ambience, motion sound and score generated with the clip
- ✓6 aspect ratios — 9:16, 16:9, 1:1, 4:3, 3:4 and cinematic 21:9
- ✓End-frame control — set a last frame to land the shot where you want
For creator faces, product films & ads
Seedance 2 is the flagship pick when realism and identity matter: real-person talking clips and UGC-style hooks from a single photo, product films that need an exact runtime, character-consistent storytelling, and widescreen 21:9 trailers — anywhere you need a real face to stay believable across the whole shot.

Seedance 2, explained
What is Seedance 2, and why is real-face reference its standout feature?⌄
Seedance 2 is ByteDance's flagship image-to-video, text-to-video and reference-to-video model, exposed on ClipTrend.ai through the Kie video endpoint so you can generate without a ByteDance developer account. It animates a still photo, renders a prompt into motion, or follows an omni reference — a real face, a still image, a video clip or audio — into a clip you can set anywhere from 4 to 15 seconds, with a generated soundtrack baked in.
The headline difference is the real-face reference upload. Many AI video tools quietly disabled uploading a photo of a real person; Seedance 2 keeps it open, so the identity you supply is carried through the whole shot. That makes it the model to reach for when a believable, consistent human face matters more than a stylized look — and it pairs that with first-frame, last-frame and end-frame controls for precise shot framing.
Seedance 2 vs the other flagship video models⌄
Against Kling 3.0, Seedance 2 wins on real-face reference and on flexible duration — any 4–15s versus Kling's fixed 5 / 8 / 10 / 15s rungs — while Kling 3.0 leads on multi-shot cinematic sequencing. Against Veo 3, Seedance 2 wins on real-face upload, the wide 21:9 frame and runtime flexibility; Veo 3 is the call when you want Google's native audio model. Against Grok Imagine, Seedance 2 is the realism and identity choice with six aspect ratios and built-in audio, while Grok Imagine stays cheaper for stylized, non-photoreal work.
Frequently asked questions
Can I upload a photo of a real person to Seedance 2?⌄
Yes — Seedance 2 is the model on ClipTrend.ai that still accepts a real-face reference upload. Drop in a photo and its omni reference carries that identity through the whole clip, so the person you uploaded is the one who moves and reacts on screen. An automated safety check runs first and may block flagged inputs.
How long can a Seedance 2 video be?⌄
Any length from 4 to 15 seconds, set in one-second steps. Unlike models locked to 5 or 10 seconds, you can land on exactly the runtime your edit needs — a 7-second hook or a 13-second walkthrough — without looping or padding.
Does Seedance 2 add audio, and does the output have a watermark?⌄
Seedance 2 generates a matching soundtrack and sound effects with the video, no separate audio pass. Every generation exports a clean MP4 with no ClipTrend watermark, the same container as the Kling and Veo tiers.
Seedance 2 vs Kling 3.0 — which should I use?⌄
Pick Seedance 2 when you need a real-face reference to stay consistent or an exact 4–15s runtime — Kling 3.0 doesn't take real-face upload and locks to fixed 5 / 8 / 10 / 15s lengths. Pick Kling 3.0 when you want multi-shot cinematic sequencing instead.
