Video Generation
About this knowledge base
Video generation produces audiovisual content that changes over time from text, images, or existing clips. It is not simply “many images generated in sequence”: shots, frame rate, motion, identity continuity, audio, subtitles, post-production, and failure recovery all determine delivery quality. This course uses a short-shot workflow: storyboard first, generate one shot at a time, validate a task package offline, then finish the work through human editing and review. Inputs, shot transformations, and release candidates must also be tracked separately with versions, object-level access control, and revocation/deletion propagation.
Where this course fits in the overall route
It sits near the end of the Extended Applications and Complex Collaboration stage and combines prompting, multimodal input, asynchronous jobs, evaluation, safety, and production engineering. After completing it, you should be able to have an Agent orchestrate video work without delegating creative or release decisions to the Agent entirely.
Learning objectives
- Understand the relationship among frames, frame rate, duration, resolution, shots, and a timeline.
- Explain intuitively both spatial quality and temporal consistency in video generation.
- Break a creative brief into a storyboard, shot list, generation jobs, post-production, audio, and subtitle interfaces.
- Design layered acceptance for motion, identity, continuity, audio/video synchronization, and safety.
- Use an offline validator to check timelines, rights information, recovery rules, human-review gates, and the provenance chain of
source_revision,transform_id, andrelease_id.
Prerequisites
Before starting, it is helpful to understand composition, conditioning, and quality boundaries in Image Generation; describe shot constraints with Prompt Engineering; understand asynchronous jobs and failure recovery through Workflow Automation; and express task packages with JSON. These are task-oriented capabilities, not a requirement to complete four entire courses first. No editing-software experience is required; this course focuses on transferable workflows and interfaces.
Recommended order
- Video fundamentals and timing — read frame rate, duration, shots, and timelines correctly.
- Generation principles and temporal consistency — understand why video adds a temporal challenge beyond image generation.
- Text and image conditioning — choose text, first-frame, reference-asset, or existing-video conditioning.
- Storyboarding and shot lists — break a story into generatable short shots.
- Generation and post-production assembly workflow — manage asynchronous jobs, versions, and the handoff to post-production.
- Audio, captions, and accessibility interfaces — treat synchronized audio and captions as formal deliverables.
- Quality, motion, and identity-consistency evaluation — establish frame-, shot-, and finished-piece reviews.
- Cost, failure recovery, and provenance governance — limit retries, preserve provenance, and release safely.
- Project: Video Generation Job Package Validation — complete a fully offline storyboard-job-package check.
Hands-on project
Follow the project guide, inspect the example job package, and run the validator, compatibility smoke test, and full contract and CLI tests. The scripts do not request an API or create video or audio files.
Mastery checklist
- Can turn a creative idea into a shot list with explicit start/end times, shot language, and continuity anchors.
- Can explain the difference between within-frame quality and across-frame consistency.
- Can design the interfaces among generation, download, transcoding, editing, captioning, voice-over, and review.
- Can retry only the failed shot rather than remaking the entire piece each time.
- Can record asset authorization, consent, generation history, and a Content Credentials plan.
- Can enforce object-level authorization/ACL before preview, scoring, or model access, and invalidate shot candidates, finished derivatives, caches, and links as planned when access is revoked or data is deleted.
- Can distinguish synthetic-content disclosure from factual claims; the latter require independent evidence sufficient for
evidence_supported. - The offline job-package validator and its tests pass.
Relationship to other knowledge bases
- Image Generation provides foundations in composition, visual conditioning, editing, and image quality.
- Text-to-Speech and Speech Recognition support voice-over, transcription, and caption proofreading.
- Runtime Monitoring supports long-job state, retries, and cost observation.
- AI Safety and AI Governance carry release-risk assessment and accountability records.
- Versioning, Deletion, and Authorization supplies general governance semantics for versions, object-level authorization/ACL, and revocation/deletion propagation.
