Reuse Image Studio patterns and shared preflight/subscription checks via `main_video_generation`. + +--- + +## Core principles +- **Provider/model abstraction**: One interface; pluggable providers; auto-routing by use case, cost, SLA. No provider jargon in UI. +- **Preflight first**: Auth, quota/tier gating, safety, and cost estimation before hitting any model. +- **Guided success**: Templates, motion/audio presets, platform defaults, inline guardrails (duration/aspect/size) with surfaced costs. +- **Cost transparency**: Per-run estimate + actual; show price drivers (resolution, duration, provider). Support “draft/standard/premium” quality ladders. +- **Governed delivery**: Safe file serving, ownership checks, audit logs, usage telemetry. + +--- + +## Modules (user-facing scope) +- **Create Studio**: t2v, i2v with templates, motion presets, aspect/duration defaults; audio opt-in (upload/TTS). +- **Avatar Studio**: Talking avatars (short/long), face/character swap, dubbing/translation; voice optional. +- **Edit Studio**: Trim/cut, speed, stabilize, background/sky replace, object/face swap, captions/subtitles, color grade. +- **Enhance Studio**: Upscale (480p→4K), VSR, frame-rate boost, denoise/sharpen, temporal outpaint/extend. +- **Transform Studio**: Format/codec/aspect conversion; video-to-video restyle; style transfer. +- **Social Optimizer**: One-click platform packs (IG/TikTok/YouTube/LinkedIn/Twitter), safe zones, compression, thumbnail. +- **Asset Library**: AI tagging, versions, usage, analytics, governed links. + +--- + +## Model catalog (pluggable; WaveSpeed-led but not locked) +- **Text-to-video (fast, coherent)**: `wavespeed-ai/hunyuan-video-1.5/text-to-video` — 5/8/10s, 480p/720p, ~$0.02–0.04/s [[link](https://wavespeed.ai/models/wavespeed-ai/hunyuan-video-1.5/text-to-video)]. +- **Image-to-video (short clips)**: `wavespeed-ai/kandinsky5-pro/image-to-video` — 5s MP4, 512p/1024p, ~$0.20/0.60 per run [[link](https://wavespeed.ai/models/wavespeed-ai/kandinsky5-pro/image-to-video)]. +- **Extend/outpaint**: `alibaba/wan-2.5/video-extend` — extend clips with motion/audio continuity. +- **High-speed t2v/i2v**: `lightricks/ltx-2-pro/text-to-video`, `lightricks/ltx-2-fast/image-to-video`, `lightricks/ltx-2-retake` — draft/retake flows with lower latency. +- **Character/face swap**: `wavespeed-ai/wan-2.1/mocha`, `wavespeed-ai/video-face-swap`. +- **Video-to-video restyle/realism**: `wavespeed-ai/wan-2.1/ditto`, `wavespeed-ai/wan-2.1/synthetic-to-real-ditto`,

`wavespeed-ai/flashvsr` (upscaler), `wavespeed.ai/video-outpainter` (temporal outpaint). +- **Future slots**: Additional providers slotted via the same adapter interface (cost/SLA caps). + +Provider-agnostic API note: each model sits behind a provider adapter implementing a common contract (generate/extend/enhance, capability flags, pricing metadata); routing is driven by policy + user intent (quality, speed, budget, platform target). + +--- + +## Backend implementation +- **Orchestrator**: `VideoStudioManager` delegates to module services; `main_video_generation` entrypoint mirrors `main_text_generation`/`main_image_generation`. +- **Services**: `create_service`, `avatar_service`, `edit_service`, `enhance_service`, `transform_service`, `social_optimizer_service`, `asset_library_service`. +- **Provider adapters**: WaveSpeed, LTX, Alibaba, HeyGen, Decart, etc. registered via a provider registry with capability metadata (resolutions, duration caps, cost curves, latency class, safety profile). +- **Preflight middleware**: auth → subscription/limits → capability guard (resolution/duration) → cost estimate → optional user confirm → enqueue job. +- **Jobs & storage**: async job queue for long video runs; store artifacts in user-scoped buckets; signed URLs for delivery; CDN-friendly paths. +- **Tracking**: usage + cost logging per op; surfaced to UI and billing; audit logs for asset access. +- **Safety**: optional safety checker flags from providers; block/blur pipelines if required; PII guardrails for translations/face swap. + +--- + +## Frontend implementation +- **Layout reuse**: `VideoStudioLayout` (glassy, motion presets) + dashboard cards showing status, ETA, and cost hints. +- **Guidance-first UI**: platform templates, duration/aspect presets, motion presets, audio toggle; inline cost estimator tied to preflight. +- **Async UX**: polling/websocket for job status, resumable downloads, progress with ETA based on provider latency class. +- **Editor widgets**: timeline for trim/speed; face/region selection for swap; caption/dubbing panels; preview player with quality toggles. +- **Cost surfaces**: draft/standard/premium toggle that maps to provider/model choices; show estimated $ and credit impact before submit. + +--- + +## Preflight & cost transparency +- Inputs validated against tier caps (duration, resolution, monthly ops). +- Cost estimate = provider pricing × duration/resolution × quality tier; show before submit. +- Post-run actuals recorded; user sees “estimated vs actual” and remaining quota/credits. +- Fallback ladder: prefer lowest-cost that meets spec; escalate to higher-quality if user selects premium. + +--- + +## Use cases (creator + platform) +- Social short: 5–10s vertical t2v/i2v with audio; auto IG/TikTok/YouTube Shorts pack. +- Product hero: i2v + subtle motion, then outpaint/extend to 15s, upscale to 1080p, add captions. +- Avatar explainer: photo + audio → talking head; optional translation + captions for LinkedIn/YouTube. +- Restyle/localize: video-to-video with style transfer + dubbing/translate; maintain duration/aspect per channel. +- Upscale/repair: ingest UGC, denoise/sharpen, flashvsr upscale, safe-zone crops for ads. + +--- + +## Implementation roadmap (condensed) +- **Phase 1 (Foundation)**: `main_video_generation`, provider registry, Create Studio (t2v/i2v), preflight/cost, storage + signed URLs, basic dashboard + job status. +- **Phase 2 (Adapt & Enhance)**: Avatar Studio, Enhance (VSR, frame-rate), Transform (format/aspect), Social Optimizer, cost telemetry UI. +- **Phase 3 (Edit & Localize)**: Edit Studio (trim/speed/replace/swap), dubbing/translate, face/character swap, outpaint/extend, asset library v1 with analytics. +- **Phase 4 (Scale & Govern)**: Performance tuning, batch runs, org/policy controls, advanced analytics, provider failover testing. + +--- + +## Metrics (short) +- **Quality & success**: generation success rate, CSAT on outputs. +- **Speed**: P50/P90 job time by tier/provider; preflight-to-submit conversion. +- **Cost**: estimate vs actual delta; cost per minute by tier; quota utilization. +- **Adoption**: DAU/WAU using video modules; module mix (create/enhance/edit). + +--- + +## Risks & mitigations (short) +- API/provider drift → contract tests + capability registry versioning. +- Cost overruns → hard caps per tier, preflight estimates, auto-downgrade to draft. +- Long-job failures → resumable jobs, chunked uploads, retry with backoff/failover provider. +- Safety/abuse → safety flags, PII guardrails, per-tenant policy toggles, audit logs. + +--- + +## Next steps +- Finalize provider adapter contracts and register the initial set (WaveSpeed, LTX, Alibaba, HeyGen). +- Wire `main_video_generation` with shared preflight/subscription middleware. +- Ship Create Studio with cost surfaces and platform templates; add Enhance (flashvsr) and Extend (wan-2.5) as first enrichers.
