ALwrity Video Studio: Implementation Plan

Purpose

Deliver a creator-friendly, platform-ready video studio that hides provider/model complexity, guides users to successful outputs, and stays transparent on cost. 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].
• Image-to-video (short clips): wavespeed-ai/kandinsky5-pro/image-to-video — 5s MP4, 512p/1024p, ~$0.20/0.60 per run [link].
• 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, mirelo-ai/sfx-v1.5/video-to-video, decart/lucy-edit-pro.
• Audio/foley/dubbing: wavespeed-ai/hunyuan-video-foley, wavespeed-ai/think-sound, heygen/video-translate.
• Quality/post: 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.
• Document provider pricing metadata and map to draft/standard/premium tiers in UI.
