Seedance 2.5 AI Video Generator

Choose Seedance 2.5 when the workflow needs 1080p, up to 30 seconds, automatic duration, MP4 or MOV output, returned final frames, video-guided transformation, or more than nine images, three videos, or three audio files. Mini remains the lower-rate option for smaller 480p or 720p drafts up to 15 seconds.

Text accepts no uploads. Frames accepts exactly one starting image or two images for a start-and-end pair and rejects video or audio. Reference requires at least one uploaded image, video, or audio and is the only scene for a mixed multimodal bundle.

The reference scene accepts up to 30 images, 10 MP4 or MOV videos, and 10 MP3 or WAV audio files, with no more than 50 files in total. Images are limited to 30 MB each. Rivya currently limits each video to 95 MB and 2 to 30 seconds, with 30 video seconds in total; audio is limited to 15 MB and 2 to 30 seconds each, with 30 audio seconds in total.

Images and reference videos must each have width and height from 300 to 6,000 pixels and an aspect ratio from 0.4 to 2.5. Reference video must also contain 409,600 to 927,408 pixels in total and run at 24 to 60 frames per second. Prompts can contain up to 30,000 characters.

The no-video rate multiplies requested output seconds: 28 credits per second at 480p, 63 at 720p, or 114 at 1080p. Images or audio without a video do not switch the request to a with-video tier.

With a reference video, the rate is 17 credits at 480p, 38 at 720p, or 68.5 at 1080p, multiplied by verified input-video seconds plus reserved output seconds. Rivya preserves the 68.5 rate during multiplication and rounds the combined total up only once.

Automatic duration is the -1 choice. Because the final output length is not known before the run, Rivya reserves the 30-second output maximum; a video-guided request also includes verified input-video seconds. When valid actual usage at or below the reservation is reported, Rivya settles to it. Missing, invalid, or higher-than-reserved usage remains in reconciliation instead of triggering a hidden extra charge.

Choose text, frames, or multimodal reference input; set 480p, 720p, or 1080p; select a 4-to-30-second integer or automatic duration; and choose MP4 or MOV output.

No. The frames scene accepts only one or two images. Use the reference scene for image, video, or audio bundles; the two input styles are mutually exclusive.

Images may be JPEG, PNG, WebP, BMP, GIF, or TIFF. Videos must be MP4 or MOV. Audio must be MP3 or WAV. Every upload also has size, duration, geometry, and total-count checks before it can be used.

Yes. At 1080p, the no-video rate is 114 credits per output second, while a request containing video uses 68.5 credits across verified input-video seconds plus reserved output seconds.

Use automatic duration when the scene or source clip should guide the output length. Rivya reserves 30 output seconds in advance, so a fixed 4-to-30-second choice gives a more predictable reservation when you already know the needed length.

Use this page to validate one scene and reference hierarchy. Move to Studio when the project needs saved iterations, several source bundles, format comparisons, or a longer edit thread.
