kmlbdh Video Combine (Smart + Tiled) π
A custom ComfyUI node designed for stable, high-resolution video export β even on limited hardware.
β 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
β The Solution
kmlbdh Video Combine (Smart + Tiled) β a smarter, safer, and fully customizable alternative that:
- π Auto-detects your RAM & VRAM and suggests safe defaults
- π§± Splits frames into tiles to avoid VRAM crashes (perfect for 4K/8K)
- π¦ Streams in chunks to prevent RAM overload
- π·οΈ Supports custom
filename_prefix
for organized output - π§Ό Clean, modular, and branded for your workflow
π§ Features
- Auto Hardware Detection β Recommends safe settings for your system
- Tiled Processing β Split frames via
tile_size
(512
,1024
, etc.) - Chunked Encoding β Control memory usage with
chunk_size
- Safe Streaming β
save_images_in_memory: False
= disk-first workflow - Custom Naming β Use
filename_prefix
just like native nodes - FFmpeg-Powered β High-quality H.264/HEVC encoding
- Crash-Free β Tested on 4K+ video sequences
