Facts verified2026-09-07

Seedance 2.5 is ByteDance's flagship video model: photographic motion, native soundtrack, and up to 30 references in one shot. It writes sound and dialogue with the picture, so you do not stitch a separate track unless you want to. Feed stills, clips, and a look, and it holds character, product, and style across the shot instead of drifting after a few seconds. On Elyum it does text-to-video, image-to-video, reference-to-video, and clip edits, from 4 to 30 seconds. That last mode matters. You can drop an existing clip and restage or extend it without starting from a blank prompt. The Seedance 2.5 page lists the modes and resolutions.

The model is the same. The bill is not. On Elyum every render comes back as a free preview; you KEEP the takes you want (credits charge then) or KILL the rest for a full refund. Runway's help center states credits return only on a hard generation error. A completed but unusable clip still costs credits. Runway's pricing page lists Standard at $15/mo (625 credits), Pro at $35/mo, and Max at $95/mo. Elyum's pricing starts at Free (up to 150 credits once (our algorithm may grant them), no card), then Plus $9/mo, Pro $29/mo, Ultra $69/mo. Runway lists Seedance 2.5 (API id seedance2_5) at up to 1080p. Elyum lists 480p, 720p, and 1080p, clips 4 to 30 seconds.

Runway is the fuller production suite. It bundles Gen-4.5 and Aleph with third-party models, plus brand kits, voice clones, HDR/ProRes export, and up to 20 parallel generations on Max. Elyum does not have a timeline editor, stock footage, avatars, a mobile app, or team seats. If you need those, stay on Runway and treat Seedance 2.5 as one model in a larger kit. The keep/kill mechanic only matters if you are generating more takes than you will keep. A longer Runway rundown is on the Runway alternative page.

Seedance 2.5 on Runway

Runway offers Seedance 2.5 as a licensed third-party model (API id seedance2_5) and its model docs say it generates up to 1080p. Standard ($15/mo, 625 credits) is listed with all AI video and image models; Pro ($35/mo, 2,250 credits) and Max ($95/mo, 9,500 credits) say all models. The Free plan exists (125 one-time credits, 5GB storage, limited model selection). Whether Seedance 2.5 sits in that limited free set is not published. Runway also does not publish a Seedance 2.5 credit rate, so a 5-second keep cannot be priced from official copy.

A bad take still bills if the job completes. Runway returns credits automatically only on a hard generation error. Trustpilot reviewers have written that the model can ignore a detailed prompt and still burn credits, that a $15 plan buys about 10 short (5s) renders with no credit rollover on Standard, and that refund requests are often denied. Monthly plan credits reset each cycle (Max allows one month of rollover). Top-up credits (minimum 1,000) do not expire. Paid plans list no watermarks. Commercial-use terms were not quoted from Runway's ToS in the research used here, so treat that as unconfirmed.

Seedance 2.5 on Elyum

On Elyum, Seedance 2.5 runs 4 to 30 seconds at 480p, 720p, or 1080p. Modes: text-to-video, image-to-video, reference-to-video, and clip edits. A keep at 480p is 40 credits ($0.40) for 5 seconds and 120 credits ($1.20) for 15. At 720p: 95 credits ($0.95) and 285 credits ($2.85). At 1080p: 130 credits ($1.30) and 390 credits ($3.90). Per-second rate tokens are 8, 19, and 26.

Preview is free. You judge the take, then KEEP it (that is the only moment credits are charged) or KILL it (full refund, automatic). A failed generation is never charged. Free meters kills at one a month; Plus, Pro, and Ultra kill freely. Kept takes download clean and full quality, no watermark, commercial use included. Use the web studio or call the same balance from Claude, ChatGPT, and Cursor via the MCP server and the REST API.

Clip length

Elyum runs Seedance 2.5 from 4 to 30 seconds. Runway's max clip length for this model was not confirmed in the research.

You already run a Runway workspace and want Seedance 2.5 as one more third-party model.
You need up to 20 parallel generations on Max, or an API already wired to Runway.

Pick Elyum when

You iterate. Preview is free; a kept 480p 5s take is 40 credits ($0.40), and a KILL refunds.

Getting the most out of Seedance 2.5

Write camera like a shot list: lens, move, and stop. Seedance 2.5 reads slow dolly in, 35mm, hold on the hands more reliably than the word cinematic.
If you want native audio, put dialogue in quotes and name the room tone in the same prompt. The model writes sound with the picture; a silent prompt often yields a thin track.
Use references as roles, not a pile. Tag which still is the face, which clip is the motion, which frame is the grade. It holds up to 30, but conflicting wardrobes will still fight.
For clips past 10 seconds, write beats: what happens at the start, the turn, and the end. Unstructured long prompts drift even when the look stays locked.
When editing an existing clip, say what must stay (wardrobe, framing, product) and what may change (action, line, camera). Restage is not make it better.
Avoid stacked style words and two times of day. Photographic motion breaks when you ask for noon sun and neon night in one shot.
