## FAQ

### What is Seedance 2.5 in Listnr Studio?

Seedance 2.5 is a named video model for longer multimodal clips with native audio and tighter instruction following. You write the beats here, then continue at /create?tool=seedance-2-5. Listnr Studio requests one Seedance clip from Runware instead of stitching still frames into a slideshow.

### When should I choose Seedance 2.5 instead of Seedance 2.0?

Choose Seedance 2.5 when the brief needs a longer hold, denser spoken or visual instructions, or an auto duration. Seedance 2.0 is better for a short cinematic beat between four and fifteen seconds. Open /create?tool=seedance-2-5 when that longer multimodal clip is the goal.

### How long can a Seedance 2.5 clip run?

Seedance 2.5 accepts four to thirty seconds, and Listnr Studio also offers auto duration for this model. The default is eight seconds. If you need a tight cinematic burst under fifteen seconds, Seedance 2.0 is the closer match.

### What does auto duration mean on Seedance 2.5?

Auto lets Seedance 2.5 pick a length inside its allowed range from the prompt's pacing. Use it when the brief has several beats and you do not want to lock a number. Switch to a manual length when the destination, such as a short or an ad slot, needs an exact runtime.

### How should I write a Seedance 2.5 instruction?

List the beats in order, then add camera moves, lighting, and the native audio you want under the picture. Seedance 2.5 follows denser instructions than 2.0, so name what must stay on screen and what can change. Keep each beat concrete enough that the preview can be checked against the brief.

### Does Seedance 2.5 keep native audio with the picture?

Yes. Seedance 2.5 generates synchronized audio in the same clip, including speech, ambience, or effects you described. Treat music in Listnr Studio as an optional bed under that native mix, and skip a bed when dialogue or texture needs the track dry.
