Architecture Overview

Mastering local AI video generation on consumer GPUs: how chaining Wan 2.1 14B Image-to-Video with TeaCache diffusion acceleration doubles rendering throughput, while RIFE v4.6 optical flow frame interpolation elevates 16fps output to liquid-smooth 60fps 4K broadcast footage without cloud API subscription fees.

[ComfyUI Wan 2.1 Local Directing Architecture]
Model: Wan2.1_I2V_14B_720P
Acceleration Node: TeaCache_For_Wan (Threshold: 0.15, Cache_Type: dynamic_residual)
Frame Interpolation: RIFE_v4.6_Optical_Flow (Multiplier: 4x, Target_Cadence: 60fps)

Image-to-Video Positive Prompt:
Cinematic 4K broadcast-quality motion sequence. Photorealistic physical interaction, precise fluid dynamics, volumetric atmospheric lighting, authentic surface displacement, and true optical depth of field. High-speed cinematic shutter timing with zero temporal flicker or latent drift. Smooth organic inertia matching real-world mechanical and biological kinematics.

Camera Trajectory Directive:
Smooth stabilized cinematic tracking shot, steady lateral pan with subtle forward pedestal drift. Natural focal lens curvature (35mm anamorphic), zero digital jitter, zero erratic warping, locked perspective geometry.

TeaCache & Sampler Configuration:
Sampler: UniPC / DPM++ 2M SDE Karras
Steps: 30
CFG Scale: 6.0
TeaCache Threshold: 0.15 (Skip redundant attention layers during mid-diffusion steps)
RIFE Interpolation Pass: 15fps input -> 60fps output with motion blur synthesis.

temporal flicker, morphing artifacts, distorted limbs, plastic synthetic skin, frame judder, abrupt camera teleportation, oversaturated cartoon bloom, watermark, text, low bitrate compression.
