Facts verified2026-09-07

Seedance 2.0 is ByteDance's video model for camera-like motion and lighting. Faces, products, and rooms stay consistent across the clip instead of drifting into stylized mush. On Elyum it does text-to-video, image-to-video, reference-to-video (up to 9 stills and 3 clips), and clip edits, with sound and dialogue in the same take. Clips run 4 to 15 seconds. Modes and rates sit on the Seedance 2.0 page.

The model is the same. The bill is not. Elyum holds credits on a preview, then charges only if you keep the take or refunds the hold if you kill it. Runway deducts credits when a generation completes and returns them only on a hard generation error. Runway's pricing page lists Standard at $15/mo (625 credits), Pro at $35/mo (2,250), and Max at $95/mo (9,500). Elyum pricing is Free (up to 150 credits once (our algorithm may grant them)), Plus $9/mo, Pro $29/mo, Ultra $69/mo, and 1 credit = $0.01. Runway paid tiers add brand kits, voice clones, and HDR/ProRes on Max. Elyum does not have a timeline editor, stock footage, avatars, a mobile app, team seats, or a community feed.

Runway still wins if you need Gen-4.5 or Aleph in the same project, or Max extras like HDR/ProRes and image sequences. Seedance 2.0's credit cost on Runway is not published; do not guess a per-clip number. For the 2.5 cut of the same family, see Runway vs Elyum for Seedance 2.5.

Seedance 2.0 on Runway

Runway lists Seedance 2.0 as seedance2, seedance2_fast, and seedance2_mini in its developer model list. Standard ($15/mo, 625 credits), Pro ($35/mo, 2,250), and Max ($95/mo, 9,500) include all AI video and image models. The free tier (125 one-time credits, 5GB storage) has a limited model set; whether seedance2 is on that set is not stated. The Seedance 2.0 credit rate is not published. A completed-but-unusable take is not refunded. Only a hard generation error returns credits.

The rest of Runway is the reason people stay. Paid tiers add an agentic collaborator, parallel gens (5 / 15 / 20), audio tools, and 4K upscaling (unlimited on Pro and Max). Pro adds a brand kit and a voice clone. Max adds HDR/ProRes/image sequences, 500GB, and one-month credit rollover. Top-ups (min. 1,000) do not expire; Standard and Pro monthly credits reset. A Trustpilot reviewer wrote that a $15 plan buys about 10 short 5s renders, with no rollover. That is plan yield, not a Seedance 2.0 rate.

Seedance 2.0 on Elyum

On Elyum, Seedance 2.0 runs 4 to 15 seconds at 480p, 720p, or 1080p, with native audio. Rates are 6 credits per second at 480p, 16 at 720p, and 24 at 1080p. A 5s keep is 30 credits ($0.30) at 480p, 80 credits ($0.80) at 720p, or 120 credits ($1.20) at 1080p. A 15s keep is 90 credits ($0.90), 240 credits ($2.40), or 360 credits ($3.60). Start on Free (up to 150 credits (our algorithm may grant them), no card). Plus is $9/mo.

Every render comes back as a free preview. Keep it and credits leave then. Kill it and the hold is refunded in full. Failed generations are never charged. Free gets one kill a month; Plus, Pro, and Ultra kill freely. Kept files download clean, no watermark, commercial use included. One balance covers 50+ models. Drive the studio from Claude, ChatGPT, or Cursor via the MCP docs or the REST API.

Where the two differ

When credits leave

Elyum charges when you keep a preview. Runway charges when a generation completes. The Seedance 2.0 credit rate on Runway is not published.

Bad but finished takes

On Elyum, kill refunds the hold in full (one kill per month on Free; paid plans kill freely). Runway returns credits only when a generation ends in a hard generation error.

Clip length and resolution

Elyum Seedance 2.0 is 4 to 15 seconds at 480p, 720p, or 1080p. Runway's duration and native resolution for seedance2 are not published. A 1080p cap in third-party notes applies to Seedance 2.5 on Runway, not 2.0.

Editor and production extras

Runway paid plans include brand kits, voice clones, 4K upscaling, and on Max HDR/ProRes and image sequences. Elyum has no timeline editor, stock footage, avatars, mobile app, team seats, or community feed.

API and MCP

Watermark and commercial use

Elyum kept takes have no watermark and include commercial use. Runway paid plans have no watermarks; commercial-use terms were not independently verified from official ToS in this research.

Pick Runway when

You want Seedance 2.0 in the same workspace as Gen-4.5, Aleph 2.0, and Act-Two.

You want the seedance2_fast or seedance2_mini SKUs listed in Runway's model docs.
You already pay for Runway's API or Pro MCP and do not want a second studio.

Pick Elyum when

Previews are free. Credits move only when you keep a Seedance 2.0 take.
A failed generation is never charged. Paid plans kill bad takes with a full refund.
Plus is $9/mo versus Runway Standard at $15/mo, with listed rates about 20% under comparable hosts.

Getting the most out of Seedance 2.0

Write a shot list, not a mood. Name lens, move, and light (35mm, slow dolly in, overcast window). Seedance 2.0 holds faces and rooms when the camera instruction is singular.
Give one primary action and a rest. A 4 to 15 second clip cannot hold three plot turns. Extra verbs smear motion and fight the realism the model is built for.
For reference-to-video, use stills to lock face, wardrobe, and product. Use clips to lock gait or a beat. Elyum accepts up to 9 stills and 3 clips on this model.
Put spoken lines and room tone in the prompt. Sound and dialogue render with the picture. A silent prompt often yields thin ambience you then have to replace.
When you edit a clip, say what must not change (face, label, framing) and what must (color, two extra seconds, a new line). Vague restyle prompts drift the subject.
Avoid stacked style names and readable on-screen type. The model is tuned for camera-like footage. Poster text and mixed aesthetics usually lose the realism.

Frequently asked questions

How much does a Seedance 2.0 video cost on Elyum vs Runway?

On Elyum a kept 5s clip is 30 credits ($0.30) at 480p, 80 credits ($0.80) at 720p, or 120 credits ($1.20) at 1080p. A 15s keep is 90 credits ($0.90), 240 credits ($2.40), or 360 credits ($3.60). Runway does not publish a Seedance 2.0 credit rate. Standard is $15/mo for 625 credits.

Is Seedance 2.0 the same model on both?

Yes. Same ByteDance weights via the vendor. Platforms differ in price, limits, and refund policy. Runway exposes seedance2, seedance2_fast, and seedance2_mini. Elyum lists one Seedance 2.0 SKU at 480p, 720p, and 1080p for 4 to 15s. Runway's native resolution and duration for 2.0 are not published. A 1080p note in research is for Seedance 2.5 on Runway, not 2.0.

What happens to a bad Seedance 2.0 take?

On Elyum you kill it and the credit hold is refunded in full. Failed generations are never charged. Free allows one kill a month; paid plans kill freely. On Runway, credits return only when a generation ends in a hard generation error. A completed clip that is off-prompt or low quality is not refunded. That gap is a frequent user complaint on Trustpilot.

Do I need a subscription to use Seedance 2.0 on Elyum?

No. The Free plan includes up to 150 credits once (our algorithm may grant them), with no card. Previews are free on every plan. Credits are charged only when you keep a take. Plus is $9/mo if you want paid-plan kills and a monthly allotment.

Does Runway watermark Seedance 2.0 exports?

Paid Runway plans list no watermarks. Free-tier watermark status was not confirmed on the official pricing page used in research. Elyum kept takes download with no watermark.

Can I run Seedance 2.0 from an API or chat tool?

Runway has a public developer API that includes Seedance among third-party models, plus Runway MCP on Pro. Elyum has MCP and REST so you can drive the same credit balance from Claude, ChatGPT, or Cursor. If you are leaving Runway's suite, the Runway alternative states what Elyum does not copy (timeline, stock, avatars, mobile, team seats).
