Important Suggestions for Rendering Videos Over 200 Frames

Rendering long videos (above 200 frames) can be challenging in ComfyUI. To ensure success, follow these guidelines:

1. Remove the "Video Combine" Node. Instead, use the "Save Image" node.

Reasons for Removing the 'Video Combine' Node

• ⚠️ The VHS Video Combine node often crashes silently when processing hundreds of frames (200+), depending on the resolution. Therefore, removing it would be safer.
• You cannot place both the "Save Image" node and the "Video Combine" node at the same level, as the execution order is uncertain. The VHS node might run first and crash, preventing the "Save Image" node from executing.
• To determine the execution order, use ComfyUI-Manager:

  • Turn on the Badge: #ID Nickname.

  • A small number will appear on top of each node in your workflow. Nodes execute in ascending order based on these numbers if they are at the same level.

    

2. Output Path Configuration

⚠️ Make sure you set the correct path, or you will not find the result in the file browser.

3. Limiting the Number of Frames

Use a machine with sufficient resources:

• Large Machine: 24GB VRAM, 48GB RAM
• Extra Large Machine: 48GB VRAM, 48GB RAM

⚠️ Render no more than 200 frames at a time:
