Wan 2.1 Control LoRA: Efficient Video Generation

Wan 2.1 Control LoRA introduces a lightweight and efficient approach to video generation, providing an alternative to traditional ControlNet methods. Designed specifically for Wan 2.1 models, these depth and tile-based LoRAs allow users to guide Wan 2.1 video structure and detail without increasing inference costs. Unlike ControlNet, which can be resource-intensive and complex to train, this Control LoRA seamlessly integrates with Wan 2.1, ensuring precise and optimized outputs with minimal computational overhead.

How to Use Wan 2.1 Control LoRA Workflow?

Nodes in the Wan 2.1 workflow are organized for clarity when using the Depth and Tile LoRAs with Wan 2.1.

1. Wan 2.1 Depth Controlnet Video Group
2. Upscaling - Tile Controlnet Group

Unmute the group you'd like to use and upload your desired video. Enter your positive text and, if necessary, adjust the Wan 2.1 video settings like duration and resolution for both groups.

All the rendered Wan 2.1 Control LoRA videos will be saved in the Outputs folder in ComfyUI.

1 - Depth Control LoRA Video Group

This Depth Control LoRA group is used to extract depth information from video clips to enhance Wan 2.1 video generation. It offers a more structured and depth-aware alternative to traditional ControlNet methods, helping you create more coherent and visually consistent outputs with Wan 2.1.

Unmute it if it's muted.

To use it, upload a video and adjust the resolution and length based on your hardware limits and project needs. Higher resolutions can capture more detailed depth, but may increase processing time and VRAM usage. Shorter clips will run faster. Test different settings to find the right balance between quality and performance for your Wan 2.1 workflow.

2 - Upscaling - Tile Control LoRA Group

This is your Tile LoRA Usage group, designed to upscale videos while preserving detail and consistency. By leveraging the Tile Control LoRA method with Wan 2.1, you can enhance video resolution efficiently without significant performance loss. Ensure that your input video is under 1K resolution, as the workflow supports upscaling up to 1.5K. However, be cautious of potential out-of-memory crashes, particularly when processing longer videos or working with GPUs with limited VRAM. Adjust settings as needed to achieve the best balance between quality and system performance.

Unmute the group if it is muted.

Upload your video for upscaling using the Tile Control LoRA, which enhances resolution while maintaining visual consistency and detail in Wan 2.1 outputs. The input video should be under 1K resolution, as the workflow allows for upscaling up to 1.5K. However, be mindful of potential out-of-memory crashes, especially when working with longer videos or limited VRAM. Adjust your settings accordingly to balance quality and performance for the best results with Wan 2.1.
