Open-source digital-human koubo Skill vs Cyanvid: which to use
Compare the open-source Agent Skill digital-human-koubo (photo + script → lip-synced talking-head) with Cyanvid’s subscription studio (text/image → multi-model clips). Inputs, cost framing, use cases, and when to pick each.
digital-human-koubo is an open-source Agent Skill: a local agent plus cloud generation for “authorized photo + script → lip-synced digital human + packaged cut.” Cyanvid is a subscription site: text-to-video and image-to-video in the browser across multiple models. It does not currently offer face swap, lip sync, or audio-driven talking-head features.
They sit next to each other but solve different jobs: one is a talking-head production line; the other is a multi-model short-clip studio. Pick by task—don’t force a “who is the official clone” comparison.

Inputs and outputs
| Dimension | digital-human-koubo (open-source Skill) | Cyanvid (subscription) |
|---|---|---|
| Typical inputs | Authorized face photo + spoken script (optional style, captions, scene) | Text prompt; or PNG/JPEG reference + motion notes |
| Runtime | An agent that can install Skills, attach remote MCP, and run local commands (e.g. Claude Code / Codex) plus ffmpeg / whisper / Node (Remotion), etc. | Browser account; generation and history stay on-site |
| Core output | Lip-synced talking-head cut with packaging options described in the repo | Private, watermark-free short MP4; duration/resolution depend on enabled models |
| Explicit non-goals | Not a one-click SaaS; full pipeline needs local edit tooling and a cloud credits account | No face swap, lip sync, or audio-to-video; no built-in timeline editor / caption tool |
| QA / flow | Repo flow: quote → first-segment trial → listenback / frame checks → local audio unify → final cut | Exact credit quote before submit; failed jobs refund; downloads from history |
Rule of thumb: fixed digital host + caption packaging → Skill route. Fast shot tests / product motion / multi-model quotes → Cyanvid. Start from photo to video, image to video, or text to video.
Cost framing (separate ledgers—do not convert 1:1)
Credit systems are not the same currency. List each side’s public numbers; never treat Renoise credits as Cyanvid credits.
Open-source side (Renoise etc., examples from the koubo README)
Author docs and live agent quotes can change:
| Example cut | Rough content | Credits (Renoise) |
|---|---|---|
| Live-commerce style ad · ~27s | Scene still + multi-segment talking-head | 482 (public README example) |
| Longer tutorial-style cuts | Many segments + demo assets | On the order of thousands (see repo cost table) |
Local time (download, QA, Remotion) and Remotion licensing for larger companies are outside those cloud credit figures.
Cyanvid side (on-site credits)
See pricing:
- New accounts get 8 welcome credits (about four entry-model 5s · 720p clips)
- Entry model Wan 2.2 5B Fast: 2 credits / 5s · 720p
- Other models cost more (e.g. Seedance 1.5 Pro at 8; Kling / Wan 3.0 / flagship Seedance tiers)—trust the studio quote before you submit
- Monthly plans (examples): Max $9.90 / 100 credits; Pro $29.90 / 400 credits (credits expire at period end, no rollover)
- Failed jobs refund automatically
How to read this: koubo’s “482 / ~27s packaged talking-head ad” is a pipeline bill; Cyanvid’s “2 credits / 5s” is a single-shot bill. Different jobs—don’t fight over per-second unit prices.
When each fits
Better fit for digital-human-koubo
- A fixed digital persona that must reappear on camera
- Lip sync, caption packaging, depth text, evidence cards, and similar talking-head craft
- You already run a local agent and can install Skills, MCP, and OS tooling
- You are fine managing Renoise (and optional TTS) accounts and confirming quotes
Better fit for Cyanvid
- You only need text- or image-to-video clips without a local pipeline
- You want multi-model choice with a visible quote before spend
- Ecommerce / Reels-style shots that do not require lip sync
- Private history, watermark-free download, and subscription credits to scale volume
Use both
- Cyanvid for B-roll / product motion / atmosphere
- koubo (or another talking-head tool) for host-on-camera lines
- Finish in a normal editor
Cyanvid does not replace a talking-head Skill; the Skill does not replace “open the browser and render multi-model clips.”
Skill vs subscription checklist
| Situation | Suggestion |
|---|---|
| Authorized photo + script → lip-synced talking-head | Evaluate digital-human-koubo (or similar); start with the official README |
| Prompt or product still → a few-second clip | Prefer the Cyanvid studio |
| Looking for koubo install / Renoise top-ups | Use the GitHub repo and Renoise docs; this page is not an install guide |
| Looking for a HeyGen-class avatar SaaS substitute | Talking-head demand ≠ Cyanvid’s current scope; see HeyGen alternative framing for ad clips, then pick a dedicated avatar product if needed |
| Want a mirror “official koubo site” for GitHub hype | Don’t—brand intent is still clone/install; honest workflow compare + generative pages help more |
Compliance notes
- Use only your own face/voice or ones you are clearly authorized to use; label AI digital-human performances.
- Feature and credit figures for koubo come from its public README / author notes and are not Cyanvid endorsements. Live pages win when numbers drift.
- Cyanvid’s boundaries follow on-site product copy; this article does not invent lip-sync features that are not shipped.
FAQ
Can Cyanvid run digital-human-koubo directly?
No. koubo installs into your local agent; Cyanvid is a web subscription studio. Different runtimes.
Why not ship a “koubo official Chinese site”?
Brand queries mostly want the repo and install steps; mirrors confuse people. We publish a workflow comparison and link back to generative pages.
How should I compare credits fairly?
Price your deliverable on each side’s own quoter. Do not convert “credits per second” across platforms.
