Seedance 1.5 Pro video generator

What is Seedance 1.5 Pro?

Seedance 1.5 Pro belongs to the 1.x line of ByteDance Seed's Seedance video models, released before Seedance 2.0 arrived on 12 February 2026. Where the 2.x generation added multimodal references (many images, clips and audio in one request), 1.5 Pro works from a prompt and up to two input images, typically a first frame and a last frame. It generates synchronized audio and, unusually in the family, supports a fixed-lens mode that holds the camera still for the whole clip.

Seedancee offers Seedance 1.5 Pro through Kie.ai (bytedance/seedance-1.5-pro) in the same workspace as 2.0 and 2.5. We keep it available because it fills two practical gaps: a locked-off camera without prompt gymnastics, and a cheaper 1080p option (on the Pro plan) for simple shots that do not need references. As with every model here, the capabilities come from a registry we verify against Kie's documentation; Seedancee is independent of ByteDance.

Configuring a generation and seeing its cost is free; generating needs a subscription. Seedance 1.5 Pro is included in both plans (Starter and Pro): Starter, from $4.99 a week, runs it at up to 720p and 10-second clips, and Pro unlocks 1080p and its full 12 seconds.

Capabilities: 1.5 Pro vs 2.0 vs 2.5

As listed by Kie.ai on 29 September 2026: 480p, 720p and 1080p output; 4 to 12 seconds; MP4 output; up to two input images; no reference images, videos or audio beyond those two frames; native audio; and the fixed_lens parameter. Automatic duration is not offered for this model.

When 1.5 Pro is the right choice

• Fixed-lens shots: product on a turntable, a locked interior, an interview-style frame, a timelapse where any camera drift would ruin the effect.
• Simple first-to-last-frame animations where you do not need extra references.
• Lower-cost 1080p clips of 4–12 seconds when 2.0's price at the same resolution is not justified.
• Reproducing older 1.x-era results for a project that must stay visually consistent with them.

It is the wrong choice for character consistency across shots (no reference images), anything longer than 12 seconds, delivery above 1080p, or workflows that depend on editing and extension. Those are Seedance 2.0 and 2.5 territory.

Workflows and audio

Text-to-video and image-to-video are supported; reference-to-video is not, because the model does not accept reference media. Native audio is generated from the prompt in the same way as on the 2.x models. The fixed-lens toggle appears in the generator only when this model is selected, since no other active model supports it.

Example prompts for Seedance 1.5 Pro

Locked camera, no movement. A hand-thrown speckled stoneware mug rotates slowly on a wooden turntable against a warm grey backdrop, soft top light, subtle shadow sweep as it turns. Clean, quiet, product-catalogue look. Sound: a faint wooden creak as the turntable rotates.

Animate from the uploaded night-time cityscape (first frame) to the uploaded sunrise version (last frame): the sky brightens gradually from deep blue to gold, streetlights fade, traffic begins to move along the waterfront. Locked wide shot. Sound: distant traffic swelling, early birds.

Steam rises from a pot of soup on a gas stove in a small kitchen in the evening, warm under-cabinet light, a wooden spoon resting on the rim. Slow gentle push-in. Sound: simmering, a soft clink.

Status and timeline

Seedance 1.5 Pro remains listed and active on Kie.ai as of 29 September 2026. ByteDance's public materials focus on 2.0 (12 February 2026) and 2.5 (31 July 2026); we have not found an official end-of-life date for the 1.x line and will update this page and the release timeline if one is announced. Prices and availability for this model can change with less notice than for the current generation.
