How long can a Seedance 2.5 video be?

Choose an integer duration from 4 to 30 seconds. Each request creates one clip; automatic duration and a separate extension workflow are not available here.

Can I generate Seedance 2.5 at 1080p or 4K?

This page supports 480p, 720p and 1080p. It does not offer 4K. The selected resolution changes the credit cost.

How do references and first/last frames work?

In Text to Video, add up to 30 images, 10 videos and 10 audio files. In Image to Video, use a first frame and optional last frame. First/last frames cannot be combined with multimodal references. Reference videos must be standard MP4/MOV, 2–30 seconds each, at most 100 MB per file and 30 seconds total. Audio accepts WAV/MP3, up to 10 MB per file and 30 seconds total.

What does Seedance 2.5 cost? Is it free?

Generation uses credits. Sign in and check the displayed total before generating; starter credits may not cover this model. Cost depends on resolution, output length and reference-video length. Confirmed failed generation tasks return their generation credits. See the pricing page for credit packs and subscriptions.

Can I use Seedance 2.5 to edit a video?

You can guide a new clip with a reference video and a prompt describing the changes. This page does not include a timeline editor or a dedicated timestamp-editing interface. Reference-video input seconds are billed together with output seconds.

Are these real Seedance 2.5 examples?

The three demo clips are published by ByteDance in its official Seedance 2.5 announcement. They demonstrate the model and are not customer outputs generated on this website. Follow the source links to check the original context.

Does it generate audio, and what changed from 2.0?

Enable generated audio for sound alongside the video. Compared with this site’s Seedance 2.0 page, 2.5 raises the single-clip limit from 15 to 30 seconds and expands multimodal reference limits. Results still depend on your prompt and inputs.
