MiniMax H3 vs Seedance 2.5: Length, 4K, Audio and Price Compared

MiniMax H3 (Hailuo 03) and ByteDance's Seedance 2.5 both turn text, a still image, first and last frames or reference images into video with audio, and both run on the same Makernice API key. Seedance 2.5 is built for long takes: up to 30 seconds, resolutions from 480p up to 4K and 16 reference images. MiniMax H3 caps clips at 15 seconds and upscales its 2K and 4K output from 768p, at a much lower per-second price.

How do MiniMax H3 and Seedance 2.5 compare at a glance?

Source: GET /v1/models and GET /v1/pricing, October 21, 2026. Catalog facts only; this post does not rank output quality.

Aspect ratios are stated for text-to-video only; for image-based modes (including reference-to-video) the framing follows your inputs.

How much does each cost per clip?

Price list v5, October 21, 2026. Clip price = per-second price × seconds (shown rounded to the cent; your quote shows the exact amount).

The gap is largest at the top. Ten seconds of MiniMax H3 at 4K costs $1.92 and ten seconds of Seedance 2.5 at 4K costs $19.55, but they are different tiers: H3's 4K is upscaled from 768p. Makernice also offers a separately priced 4K output option; ByteDance's official API tops out at 1080p (BytePlus ModelArk docs, checked October 22, 2026). Compare like with like: H3 at 768p against Seedance 2.5 at 720p is $0.72 against $2.59 for 10 seconds.

Which one should you choose?

• Choose Seedance 2.5 when a single shot must run longer than 15 seconds, when you need 1080p (H3 has no 1080p tier) or Seedance's up-to-4K tier, when you want 9:21 or adaptive framing in text-to-video, or when you need more than 5 reference images to keep a character or product consistent.
• Choose MiniMax H3 for short clips (5–15 s) where cost per second matters, for 2K or 4K deliverables where an upscale from 768p is acceptable, or when you want prompt_expansion to let the model enrich a short prompt.
• Use both: draft on MiniMax H3 at 480p ($0.30 for 5 seconds), then render the final on Seedance 2.5. Each run is quoted first, and failed generations are not charged. Note: if a finished output is blocked by output moderation for a policy violation, the run is still charged. You can contact support for a manual review.

Switch models with one field (Python)

import os, requests

API = "https://api.makernice.com/v1"
H = {"Authorization": f"Bearer {os.environ['MAKERNICE_API_KEY']}"}
prompt = "A barista pours latte art in slow motion, warm morning light, close-up."

for job in (
    {"model": "minimax-h3",   "mode": "t2v", "prompt": prompt, "duration": 10, "resolution": "768p", "aspect_ratio": "16:9"},
    {"model": "seedance-2.5", "mode": "t2v", "prompt": prompt, "duration": 10, "resolution": "720p", "aspect_ratio": "16:9"},
):
    q = requests.post(f"{API}/generations/quote", json=job, headers=H).json()
    print(job["model"], f"${int(q['amount']) / 1e6:.2f}")   # minimax-h3 $0.72 · seedance-2.5 $2.59

Quoting is free and holds nothing. To run them, create each generation with its quote_id and an Idempotency-Key, then poll — see the quickstart or the Seedance 2.5 API tutorial. Don't send generate_audio to Seedance 2.5 (400), and keep H3 durations between 5 and 15 seconds.
