Video Models

Seedance 2.5


Model ID	`seedance-2-5`
Provider	ByteDance
Credits	Per-second pricing (see below)
Duration	4–30 seconds (default 4)
Reference images	Web/App: up to 2 as first/last frame or content reference. REST API: up to 30 content references (`referenceMode: content`)
Reference video	2–30 seconds, up to 200MB; actual duration is detected automatically
Resolutions	480p, 720p (default 480p)
Aspect ratios	adaptive, 16:9, 4:3, 1:1, 3:4, 9:16, 21:9
Audio	Auto-generated
Tiers	None — do not send `tier`

Seedance 2.5 is the long-duration Seedance model on MeiGen. It supports text-to-video, first/last-frame image-to-video, content-reference images, and reference-video continuation. The Web and App pickers currently accept two content references; the REST API accepts up to 30. Frame references and reference-video continuation use adaptive ratio so the output follows the input media; text-to-video and content-reference requests can use an explicit supported ratio.

Pricing

Resolution	Direct	With reference video
480p	18 credits/sec	11 credits/sec
720p	39 credits/sec	24 credits/sec

Direct generation bills only the selected output duration. With a reference video: billable seconds = max(reference video duration + selected output duration, ceil(selected output duration × 5 / 3)) The minimum-billable floor is 7 seconds for a 4-second output, 9 for 5 seconds, and 50 for 30 seconds. Output length is always the selected 4–30 seconds; the billing floor does not lengthen the generated clip.

Scenario	Calculation	Total
480p × 5s direct	18 × 5	90
720p × 5s direct	39 × 5	195
480p, 2s reference + 5s output	11 × max(2+5, 9)	99
720p, 2s reference + 5s output	24 × max(2+5, 9)	216
480p × 30s direct	18 × 30	540

If generation fails, the full credit amount is automatically refunded.

Seedance 2.0


Model ID	`seedance-2-0`
Provider	ByteDance
Credits	Per-second pricing (see below)
Duration	4-15 seconds (default 4)
Reference images	Web/App: up to 2 as first/last frame or content reference. REST API: up to 9 content references (`referenceMode: content`)
Reference video	All three tiers. Upload must be 2–15s and ≤50MB — the platform detects the actual duration automatically
Resolutions	Direct: Mini/Fast 480p/720p, Pro 480p/720p/1080p/4K. With reference video: Mini/Fast 480p/720p, Pro 720p/1080p (no 480p, no 4K)
Aspect ratios	adaptive, 16:9, 4:3, 1:1, 3:4, 9:16, 21:9
Audio	Auto-generated

Seedance 2.0 is the three-tier Seedance option. It supports text-to-video, image-to-video (first/last frame or content reference), and video continuation. All outputs include AI-generated audio. The adaptive aspect ratio automatically matches the reference image/video dimensions. Seedance 2.0 is also the only video model with character assets: save a character once, then reference it with @ in your prompt to keep the same subject across shots. Two reference-image modes: first/last frame (default, up to 2 images) sets the opening and/or closing frame; content reference guides style or subject instead of fixing a frame position. The Web and App content-reference pickers accept up to 2 images, while the REST API accepts up to 9 with referenceMode: content. Three tiers, picked from the tier switch (Mini / Fast / Pro) in the video sidebar. Same Seedance 2.0 model, same params, just different rendering quality and price:

Mini (default): cheapest and most lightweight; 480p / 720p
Fast: quick turnaround at 480p / 720p
Pro: higher fidelity, with native 1080p and 4K rendering (4K is direct-generation only)

All three tiers support reference-video continuation — continuation output tops out at 1080p even on Pro.

Pricing

Per-second. Rate depends on tier (Mini / Fast / Pro) × whether a reference video is uploaded:

Resolution	Mini Direct	Mini With reference video	Fast Direct	Fast With reference video	Pro Direct	Pro With reference video
480p	9/sec	7/sec	13/sec	8/sec	14/sec	—
720p	16/sec	13/sec	20/sec	14/sec	22/sec	16/sec
1080p	—	—	—	—	42/sec	28/sec
4K	—	—	—	—	100/sec	—

Mini and Fast only support 480p / 720p. Pro adds native 1080p and 4K for direct generation; with a reference video, Pro is limited to 720p / 1080p (no 480p rate). With-reference-video billing rule (all tiers): billable seconds = max(reference video duration + your selected duration, min billable) Output length is always your selected duration (4–15), independent of the reference video’s length.

Your selected duration (sec)	4	5	6	7	8	9	10	11	12	13	14	15
Min billable (sec)	7	9	10	12	14	15	17	19	20	22	24	25

Examples

Scenario	Calculation	Total
Mini 480p × 4s direct	9 × 4	36
Mini 720p × 5s direct	16 × 5	80
Fast 480p × 5s direct	13 × 5	65
Fast 720p × 5s direct	20 × 5	100
Fast 720p, 5s reference + 10s selected duration	14 × max(5+10, 17) = 14 × 17	238
Pro 720p × 5s direct	22 × 5	110
Pro 1080p × 5s direct	42 × 5	210
Pro 4K × 5s direct	100 × 5	500
Pro 1080p, 5s reference + 10s selected duration	28 × max(5+10, 17) = 28 × 17	476

If generation fails, the full credit amount is automatically refunded — including all per-second charges.

Grok Video 1.5


Model ID	`grok-video`
Provider	xAI
Credits	Per-second (see below)
Duration	4-15 seconds (default 4)
Reference images	1 — first frame required (image-to-video only)
Reference video	Not supported
Resolutions	480p, 720p (default 480p)
Aspect ratios	Follows the first-frame image automatically (no manual ratio selection)
Audio	Auto-generated

xAI’s image-to-video model. A starting (first-frame) image is required — pure text-to-video is not supported. The output aspect ratio always follows your input image, and AI-generated audio is included.

Pricing

Resolution	Rate
480p	16 credits/sec
720p	28 credits/sec

Examples:

Scenario	Calculation	Total
480p × 4s	16 × 4	64
480p × 10s	16 × 10	160
720p × 4s	28 × 4	112
720p × 10s	28 × 10	280

If generation fails, the full credit amount is automatically refunded.

Veo 3.1


Model ID	`veo-3.1`
Provider	Google
Credits	Per generation (see below)
Duration	4, 6, or 8 seconds (default 4)
Reference images	Up to 2 (as first/last frame)
Reference video	Not supported
Resolutions	720p, 1080p, 4k (default 1080p)
Aspect ratios	Auto, 16:9, 9:16
Audio	Auto-generated (always on)

Google’s video generation model. Creates short clips with AI-generated audio synced to the prompt. Auto aspect ratio infers the output ratio from your prompt or reference image. Pick this for premium visual quality with native audio; for longer durations (>8s), use Seedance 2.5. Two tiers — pick one from the tier switch (Fast / Pro) in the video sidebar. Same Veo 3.1 model, same params, just different rendering quality and price:

Fast (default) — quick turnaround, balanced quality
Pro — higher fidelity, longer rendering time

Pricing

Per generation. Price depends on tier (Fast / Pro) × duration (4 / 6 / 8s). All resolutions (720p / 1080p / 4k) share the same price — picking a higher resolution costs no extra credits. Two caveats: 4k requires a paid account, and it takes noticeably longer to render.

Duration	Fast	Pro
4s	80	220
6s	125	330
8s	165	435

Examples

Scenario	Total
Fast 4s (any resolution)	80
Fast 8s (any resolution)	165
Pro 4s (any resolution)	220
Pro 8s 4k	435

If generation fails, the full credit amount is automatically refunded.

Agnes Video 2.0


Model ID	`agnes-video-2.0`
Provider	Agnes
Credits	10 per video
Daily free credits	Eligible
Duration	5 seconds (fixed)
Reference images	1 (first frame, image-to-video)
Reference video	Not supported
Resolutions	480p
Aspect ratios	Auto, 16:9, 9:16, 1:1, 4:3, 3:4

The only basic-tier video model — and the only one your daily free credits cover. Supports text-to-video and single-image first-frame image-to-video at a fixed 5 seconds / 480p. For longer clips, use Seedance 2.5; for higher resolutions, use Seedance 2.0 Pro or Veo 3.1.

Pricing

Resolution	Rate
480p	2 credits/sec

Duration is fixed at 5 seconds, so every generation costs 10 credits.

If generation fails, the full credit amount is automatically refunded.

Known Limitations

Nanobanana 2 — Stricter content filtering

This model is more sensitive to content involving real people, celebrities, brand logos, and face-swap requests. Prompts that work on other models may be rejected here. If you get a content violation error, rephrase your prompt to remove specific names or try a different model.

Flux 2 Klein / Z Image Turbo — No reference images

Both base models generate images from text only. The reference image upload section will be hidden when either is selected. If you need to use reference images, switch to any other model.

Midjourney V8.1 — Single reference image only

Midjourney V8.1 accepts only 1 reference image, while most other models accept up to 5 (Seedream 5.0 Pro accepts up to 10). In exchange it offers more control over how the reference is used (content vs. style reference).

Midjourney V8.1 — Returns 4 candidate images

Unlike other models that return a single image, Midjourney V8.1 returns 4 candidate images per generation. All candidates are saved and can be browsed in the image detail dialog. You are only charged once (15 credits at 1K / 20 credits at 2K) for all 4 images.

GPT Image 2.0 — Stricter moderation

GPT Image 2.0 applies stricter moderation than other models to real people, celebrities, brand logos, and adult/violent content. Rephrase your prompt to drop specific names, or try a different model.

Seedance 2.0 — Per-second pricing + With-reference-video minimum

Seedance bills per second, not per image — and uploading a reference video uses a separate rate table with a minimum-billable floor. See the Seedance 2.0 section above for the full rates and formula.

Seedance 2.5 — No Mini / Fast / Pro tier

Seedance 2.5 has one quality level and supports 480p / 720p. Do not send tier; use Seedance 2.0 Pro when you specifically need 1080p or 4K.

Seedance 2.0 Mini — 480p / 720p only

The Mini tier (the default) is the lightweight option, capped at 720p. For 1080p or 4K output, switch to Pro — note that reference-video continuation on Pro tops out at 1080p (4K needs direct generation with no reference video).

Grok Video 1.5 — First frame required

Grok Video 1.5 is image-to-video only — you must upload a starting (first-frame) image. Pure text-to-video is not supported. The output aspect ratio follows your input image. If you want text-to-video, use Seedance 2.5, Seedance 2.0, or Veo 3.1.

Grok Video 1.5 — 480p / 720p only

Grok Video 1.5 outputs at 480p or 720p only. For higher resolutions (1080p / 4k), use Seedance 2.0 or Veo 3.1.

Veo 3.1 — Limited aspect ratios

Veo 3.1 only supports 16:9 / 9:16 (plus Auto). Square (1:1), 4:3 / 3:4 portrait, and other ratios are not available. For wider ratio support, use Seedance 2.5 or Seedance 2.0.

Veo 3.1 — 4k costs no extra credits, but needs a paid account

720p / 1080p / 4k all cost the same on Veo 3.1, so 4k costs no extra credits. Two things to know: 4k is locked for free accounts (selecting it opens the upgrade dialog), and rendering takes longer — 4k typically takes 6–8 minutes versus 1–4 minutes for 720p / 1080p. The same 4k lock applies to Seedance 2.0 Pro.
