Seedance 1.5 Pro: Text & Image to Video Online
Bottom line
The Seedance generation before 2 — 4–14 s clips, up to 1080p, with the family's most flexible filtering. Start from a prompt or a still image in the Text to Video tool; VdoBloom shows the exact credit cost before each Seedance 1.5 Pro run, with no separate Seedance account.
Seedance 1.5 Pro is the generation ByteDance shipped before Seedance 2, and it stays in VdoBloom's lineup for two concrete reasons. The first is coverage: single-second duration control from 4 to 14 seconds, three resolution tiers up to 1080p, and six aspect ratios including 21:9 — a spec set that still handles most production briefs. The second is its content label: 1.5 Pro carries VdoBloom's HOT rating, meaning noticeably more flexible filtering than the MODERATE label applied to the entire Seedance 2 trio.
That makes the model a deliberate choice rather than a leftover. If a concept keeps getting flagged by stricter models, or if 1080p is genuinely your delivery ceiling, the older generation is arguably the better tool — same family behavior, fewer refusals, and both text and image inputs supported from one page.
As everywhere on VdoBloom, generation draws on credits, and the cost for your chosen duration and resolution appears before you run the job.

Frequently asked questions
Why choose Seedance 1.5 Pro over Seedance 2?
Two reasons: its filtering is more flexible, and its 1080p ceiling is enough for most social and web delivery. If you don't need Seedance 2's 4K tier, 1.5 Pro covers nearly the same range — six aspect ratios including 21:9 and per-second duration control.
What durations does Seedance 1.5 Pro support?
Any length from 4 to 14 seconds, selectable in one-second steps — eleven options in total. That applies to both text-to-video and image-to-video modes.
How strict is Seedance 1.5 Pro's content filter?
It carries the HOT label, the most permissive tier in the Seedance family on VdoBloom — the whole Seedance 2 trio runs stricter MODERATE filtering. Prompts that trip standard filters are more likely to generate here, though platform rules still apply.
Which formats and resolutions does it output?
Three resolution tiers — 480p, 720p, and 1080p — across six aspect ratios: 16:9, 9:16, 1:1, 4:3, 3:4, and cinema-wide 21:9. It accepts both text prompts and starting images.
