HeyGen vs Elyumfor Seedance 2.0
Elyum bills 80 credits ($0.80) for a kept 5s 720p take and refunds kills. HeyGen hosts Seedance 2.0 in its B-roll editor without a published clip price.
Seedance 2.0 is ByteDance's video model, launched February 12, 2026. It holds photoreal motion and multi-subject camera moves for a full 4 to 15 seconds, and it writes speech, room tone, and effects in the same pass as the picture. You can lock a face, a product, and a camera move with up to nine stills and three clips in one generate. That is why it shows up in character-locked product films. On Elyum the four routes are text to video, image to video, reference to video, and video editing. Live rates sit on the Seedance 2.0 page.
The weights stay the same. The bill and the house rules change. Elyum sells Seedance 2.0 by the second (6.4, 16, and 24 credits at 480p, 720p, and 1080p) and charges only on a keep. HeyGen cites Seedance 2.0 as a cinematic B-roll model inside its editor and Video Agent, drawn from a monthly credit pool: 600 on Creator ($29/mo) and 1,000 on Pro ($49/mo). HeyGen does not publish a Seedance 2.0 per-second rate, and a failed-generation policy is not in the research. Free HeyGen is 3 videos a month, 1 minute, 720p, watermark on. Elyum Free is up to 150 credits once (our algorithm may grant them), no card, with previews free. More on the HeyGen alternative page.
HeyGen is the better house if you need avatars, lip-sync, 175+ language dubbing, team seats, SSO, or a finished talking-head piece with B-roll dropped in. Elyum has none of those (no timeline, no stock, no avatars, no mobile app, no team seats). If the deliverable is an avatar video that happens to need a Seedance insert, stay on HeyGen. If the deliverable is the Seedance take, published price and kill refunds decide it. HeyGen also layers Veo 3.1 in the same B-roll pipeline.
Seedance 2.0 on HeyGen
HeyGen integrates Seedance 2.0 directly into its editor for B-roll and cinematic clips, next to Veo 3.1, Kling, Sora 2, and Flux for stills. Which plan unlocks Seedance 2.0 is not published. HeyGen's pricing page lists Creator at $29/mo ($24/mo yearly) with 600 credits, Pro at $49/mo with 1,000 credits (higher Pro tiers up to 100,000 credits/month at about $4,300), and Business at $149/mo with 1,500 credits. Cents per credit and a Seedance 2.0 draw are not published.
Free HeyGen is a permanent 3 videos per month, 1 minute each, 720p, watermark on. Paid tiers remove the watermark. Creator exports 1080p and videos up to 30 minutes; Pro and Business export 4K (Business up to 60 minutes). Those caps describe the assembled HeyGen video, not a documented Seedance 2.0 clip length. What a bad Seedance render costs on HeyGen is not published. A G2 reviewer wrote that onboarding is difficult and some functions cannot be tested without a subscription. Avatar IV is estimated at about 20 credits per minute; that is an avatar figure, not a Seedance 2.0 price.

Where the two differ
Elyum bills Seedance 2.0 per second at listed rates (1 credit = $0.01). HeyGen uses a monthly credit pool (Creator 600, Pro 1,000, Business 1,500). Cents per HeyGen credit and the Seedance 2.0 draw are not published.
On Elyum a kill refunds in full and a failed generate is never charged (Free: one kill a month; paid plans kill freely). HeyGen's failed or bad-generation policy is not published.
Elyum Seedance 2.0 runs 480p, 720p, or 1080p for 4 to 15 seconds. HeyGen Free is 720p and 1 minute; Creator is 1080p and 30 minutes; Pro and Business are 4K (Business 60 minutes, Enterprise no maximum). Those HeyGen figures are assembled-video caps, not a documented Seedance clip length.
HeyGen is an avatar platform: talking heads, voice cloning, 175+ languages, Video Agent, and third-party B-roll in one editor. Elyum has no timeline editor, stock footage, avatars, mobile app, team seats, or community feed. It is one credit balance across 50+ models on the models catalog.
HeyGen offers an API; as of February 2026 third-party sources report free API credits ended in favor of pay-as-you-go, not confirmed on an official HeyGen page. Elyum exposes the studio through the API docs and MCP from Claude, ChatGPT, and Cursor.
Paid HeyGen removes the watermark; commercial use appears allowed on paid plans but exact license terms were not confirmed from primary sources. Elyum kept takes are watermark-free, full quality, commercial use included.
Pick HeyGen when
- You already finish talking-head videos in HeyGen and want Seedance 2.0 as B-roll without leaving the editor.
- You need Video Agent to go from prompt to script, avatar, voiceover, and B-roll in one workflow.
- You need 175+ languages, custom avatars, team seats, SSO/SAML, or LMS integrations. Elyum has none of those.
- You want 4K export (Pro and up) and assembled videos up to 30 or 60 minutes, which Elyum does not offer.
Pick Elyum when
- Published per-second prices: 80 credits ($0.80) to keep a 5s 720p take, 360 credits ($3.60) for 15s at 1080p.
- Preview free, pay on keep. Kill refunds in full. A failed generate is never charged.
- Free plan is up to 150 credits once (our algorithm may grant them), no card. Plus starts at $9/mo, below HeyGen Creator at $29/mo.

Seedance 2.0 in three styles, rendered on Elyum
Getting the most out of Seedance 2.0
- Name each reference before you describe the action. Image 1 is the face lock, image 2 the wardrobe, image 3 the product, clip 1 the camera language. Then write how they combine. Seedance 2.0 holds identity when you assign roles; it drifts when you dump nine stills and hope.
- Write the soundtrack in the prompt. Put dialogue in quotes, then room tone and one or two effects. Seedance 2.0 builds audio with the picture, so a silent prompt often comes back with thin ambience and no line.
- One camera move per short take. A slow dolly-in with a locked eyeline holds for 5 to 8 seconds. Pan plus crane plus orbit in one 5s generate is how motion turns to mush.
- Budget beats against the 4 to 15 second window. A look and a spoken line fit in 5 seconds. A walk, a turn, and a product insert need 10 to 15. Do not ask for a three-scene story in one clip.
- Set aspect ratio before you generate, not after. Face and product locks framed for 9:16 will crop wrong if you later need 16:9. HeyGen avatars are cited as 9:16 and 16:9 only; Elyum lists four aspect ratios on this model.
- Specify light and weight, not mood adjectives. Soft key from camera left, practical neon, cloth with gravity. The model is known for physical accuracy. Contradictory physics (weightless fabric, heavy footsteps) is what breaks a take.
