framefields vs Replicate video models

framefields

A free Apache-2.0 library that renders video from TypeScript on the GPU, with lint and QA codes an agent can act on. It is fifteen days old, called beta, and its Claude Code install command names a plugin directory entry that was not found on 20 October 2026.

Replicate video models

One bearer token reaches more than twenty official video models at published per-second prices, each with a typed input schema, and failed runs aren't charged. Tokens have no scopes or spend cap, no SLA is published, and the terms let Replicate withdraw any model without notice.

framefields

1. Add the plugin with /plugin marketplace add gatewai-dev/framefields first; the official-directory install was not found on 20 October 2026.
2. Approve only the skia-canvas install script, as the getting-started page shows, or imports fail with a missing skia.node.
3. Check with comp.lint() and renderFrameGrid before a full renderVideo encode.
4. Call process.exit() after rendering; native GPU threads keep the script alive.
5. Preload vision models into FRAMEFIELDS_MODELS_DIR for offline or CI renders.

Replicate video models

1. Call official models at POST /v1/models/{owner}/{name}/predictions with no version, then poll GET /v1/predictions/{id} or pass webhook. Video jobs usually outlast the 60-second Prefer: wait window
2. Download the output file within the hour. API predictions lose inputs, outputs and logs after 60 minutes
3. Read the model's price tiers before setting resolution, mode or generate_audio. Kling 3.0 runs from $0.168 to $0.42 a second and Veo 3.1 doubles with audio
4. Send Cancel-After on every create. There is no idempotency key, so a blind retry is a second paid video
5. Keep credit above $20 or enable auto-reload. Low balances are throttled, and granted credit with no card is held to 6 requests a minute
