Direct answer
Start with one short, low-cost draft. Define subject, action, camera, duration and acceptance checks; attach only necessary references, then inspect continuity and audio before increasing quality.
This article answers the search question “undefined”. The source report ranks this question #97 with a 28-day volume of 700. That metric describes observed search demand, not product quality, price or availability.
What the evidence supports
- Dreamina Seedance video extension guide: Dreamina documents a Seedance 2.5 extension workflow for continuing an existing clip.
- ByteDance Seedance 2.5 announcement: Seedance 2.5 was announced July 31, 2026 with up to 30-second generation, more reference inputs, multi-round extension and timestamp editing; availability can differ by platform.
What to do
Start with one short, low-cost draft. Define subject, action, camera, duration and acceptance checks; attach only necessary references, then inspect continuity and audio before increasing quality.
A model announcement, a provider listing and access in your own account are separate facts. Use the live account and pre-generation quote as the operational evidence.
What to verify
- Confirm the exact model name and version in the live selector.
- Set duration, resolution and reference inputs before comparing access or cost.
- Save the displayed quote, job ID and settings so the result can be reproduced.
- Recheck the provider page if an offer, region or plan changes.
Open the yeha.ai video workspace and confirm the exact model, settings and displayed credit quote before submitting.
What to avoid
Do not copy a price, free quota, resolution or availability claim without its date and provider context. Search volume is not evidence that a claim is true.
