kmlbdh Video Combine (Smart + Tiled) 🚀

A custom ComfyUI node designed for stable, high-resolution video export — even on limited hardware.

❌ The Problem

VHS_VideoCombine often crashes on 4K videos due to RAM/VRAM overload, especially when using:

• 4K/8K resolution
• Frame interpolation (RIFE)
• Upscaling
• Long sequences

✅ The Solution

kmlbdh Video Combine (Smart + Tiled) — a smarter, safer, and fully customizable alternative that:

• 🔍 Auto-detects your RAM & VRAM and suggests safe defaults
• 🧱 Splits frames into tiles to avoid VRAM crashes (perfect for 4K/8K)
• 📦 Streams in chunks to prevent RAM overload
• 🏷️ Supports custom filename_prefix for organized output
• 🧼 Clean, modular, and branded for your workflow
