🎬 SkyReels V3 — V2V Extend Engine for ComfyUI
SkyReels V3 – V2V Extend Engine is a dedicated local AI video extension system inside ComfyUI, built specifically to continue existing footage seamlessly using SkyReels V3.
This workflow is entirely focused on video continuation.
No text-to-video generation.
No avatar builder.
No multi-tool playground.
Just pure shot extension control.
🧠 1. What SkyReels V3 Extend Engine Is
SkyReels V3 Extend Engine turns ComfyUI into a local AI shot continuation system where you can:
Extend an existing video forward seamlessly
Control overlap between original and generated frames
Maintain motion continuity
Loop multiple extension passes safely
Generate stable cinematic continuations on your own GPU
You don’t regenerate the scene.
You continue it.
🔁 2. Progressive Loop-Based Extension
At the heart of the workflow lies a structured loop extension system, designed to prevent temporal collapse and motion drift.
Each extension cycle:
🎞 Extracts the last frames of the current video
🧠 Encodes them into latent space
🎬 Samples the next continuation segment
🔗 Merges the result back into the timeline
🔁 Repeats for N extensions
This approach dramatically improves:
✅ Temporal stability
✅ Motion coherence
✅ Subject consistency
✅ Long-shot reliability
Perfect for:
Cinematic shot extension
Scene continuation
Slow push-ins and tracking shots
Narrative pacing extensions
🎥 3. Built on SkyReels V3 FP8 (Wan V2V)
Powered by:
Wan21-SkyReelsV3-V2V_fp8_scaled_mixed.safetensors
Optimized with:
⚡ FP8 scaled mixed quantization
🧠 SageAttention
🔄 Torch Inductor compile
💾 VRAM offloading support
🧩 Block swap optimization
Designed for:
Local GPU users
Efficient VRAM usage
Fast iteration cycles
Stable V2V continuation
Resolution defaults to 832×480 (divisible by 16) for Wan compatibility and smooth motion blending.
⚙️ 4. Designed for Real Production Pipelines
SkyReels V3 Extend Engine is built to slot directly into real workflows:
Use it after filming or rendering
Extend shots without reshooting
Add cinematic breathing room
Create AI-driven transitions
It dramatically reduces:
❌ Re-rendering entire sequences
❌ Hard scene cuts
❌ Motion discontinuity
❌ Unstable long sampling attempts
Instead of generating 20 seconds at once, you extend intelligently — segment by segment.
🚀 Why This Extend Engine Matters
Video extension is one of the hardest AI video challenges.
Long generations often cause:
Motion drift
Character deformation
Temporal artifacts
Scene instability
SkyReels V3 Extend Engine solves this by:
✅ Controlled overlap frames
✅ Loop-based continuation
✅ Stable V2V architecture
✅ Local hardware control
This is not a generic video workflow.
It is a focused cinematic extender.
