Create Seedance 2.5 Video Online

Seedance 2.5 is ByteDance's video generation model. It reads text, images, video, and audio as one context and returns a single continuous shot of 1 to 30 seconds at 480p, 720p, or 1080p, with native audio generated alongside the picture. Where it stands out is instruction-following over a longer take: camera direction, a specific ending state, and a character held steady across a set of reference images. Where it still struggles is legible on-screen text, dense crowds, and hands doing fine work — the same weak spots most video models share today. Videoify runs it as a hosted service through an upstream API provider, so there is nothing to install and no GPU of your own required.

This page is the direct way: open the generator at the top, pick text-to-video, image-to-video, or reference-to-video, write a prompt, and submit. No waitlist, no API key, no local setup. You can compose a prompt and upload references while signed out — the draft is held for an hour in your browser and restored after you sign in — but submitting a generation needs an account and enough credits.

New accounts get a starting credit balance, so your first clips come out of that grant rather than a purchase — check your balance in account settings to see what you have. Writing prompts, uploading references, and exploring the settings are always free; credits are only spent when you submit a generation. The cheapest way to stretch a free balance is 480p at a short duration: at 3 credits per second, a 5-second test costs 15 credits, and 480p is fine for checking whether a prompt is working before you commit to a 1080p take. There is no unlimited plan. Generation is billed per second by the upstream provider, so any site promising unlimited Seedance 2.5 output is either rate-limiting you somewhere or absorbing a cost it cannot sustain.

Describe one shot in this order: subject, action, setting, camera movement, lighting, style, ending state. Say what should change during the clip rather than restating what a reference image already shows. For a cinematic look, name the grammar directly — a slow dolly in, a low-angle tracking shot, anamorphic flare, golden-hour backlight, shallow depth of field — because the model follows film vocabulary more reliably than adjectives like beautiful or epic. The drone-through-a-scene shot works the same way: give it the first frame, then describe one continuous forward move and where it ends, for example "camera flies forward through the archway, past the courtyard fountain, rising to a wide view of the rooftops." One continuous move per generation beats trying to cut between two. Prompts accept up to 30,000 characters, but a focused paragraph usually beats a long stack of modifiers.

Reference-to-video takes up to 30 images, 10 videos, and 10 audio files in a single generation, and image-to-video takes a required first frame plus an optional last frame. Reference images are JPG, PNG, or WebP up to 30 MB each, and frame images also accept GIF; video is MP4, MOV, or MKV up to 200 MB; audio is MP3, WAV, AAC, M4A, or OGG up to 15 MB. More references is not automatically better — three or four consistent images of the same subject hold identity more reliably than twenty mixed ones. Name each file's job in the prompt so the model knows what to take from where: this image is the character, this one is the location, this video is the camera move.

Yes to audio input: you can attach up to 10 audio files as references in reference-to-video, and native audio is generated with every clip by default. Lip sync to a supplied audio file is not a guaranteed feature. The audio reference influences timing, rhythm, and pacing, but it is not a dubbing tool and will not reliably match mouth movement to a specific recording. If you need a spoken line, put it in quotation marks in the prompt and say who delivers it and when — for example, the woman turns to camera and says "we open at six," calm, near the end of the shot. Keep it to one or two lines, treat the result as generated audio rather than a guaranteed reading, and regenerate with simpler wording if the delivery comes out wrong.

Cost is per second of output and scales with resolution: 3 credits per second at 480p, 7 at 720p, and 12 at 1080p. A 5-second clip is 15, 35, or 60 credits. A full 30-second clip is 90 credits at 480p, 210 at 720p, or 360 at 1080p. The exact total appears on screen before you submit, so nothing is charged without you seeing the number first. For regular use, subscriptions are the cheaper route — Starter is $19.99 per month for 80 credits, Pro is $49.99 for 250, and Max is $99.99 for 600, with yearly billing lowering the monthly equivalent. Credit packs ($29.99 for 60, $89.99 for 210, $249.99 for 700) cost more per credit but never expire, which suits occasional projects. The cheapest workflow overall is drafting at 480p and only re-rendering the take you want to keep at 1080p.

720p is the default in the workspace, not a ceiling — open the generation settings and switch to 1080p before you submit. It defaults to the middle option because 720p is a reasonable balance while you are still iterating, and because 1080p costs roughly four times what 480p does per second. On text: Seedance 2.5 renders written words unreliably, so signage, logos, and UI mockups often come back garbled or misspelled. This is a known limitation of current video models rather than a settings problem. Ask for less text and larger type, keep any word short, or leave the text out and add it in an editor afterwards. The same applies to region editing and clip extension — Seedance 2.5 generates a fresh shot each time and has no local repaint or extend function, so changing one area means adjusting the prompt or references and generating again.
