# 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](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`, `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. ## Video Studio Modules ### Module 1: **Create Studio** - Video Generation **Purpose**: Generate videos from text prompts and images **Features**: -
