📃 Here’s how you can use it for fully automated processing through a folder: Black Mixture Magic Upscale_Auto Upscaler + Auto Prompt + Batch Import_with Indiv Load.json
1. Load your images by setting the image directory path in the Load Image Batch node.
2. Set the Queue amount in ComfyUI to match the number of images in your folder.
3. The workflow will automatically load and process each image sequentially without manual intervention.
4. If you prefer to queue the process manually, you can set the Queue to 1.
After processing an image, the next one will load, and you can queue the process again as needed.
If you're missing nodes, make sure you have ComfyUI Manager and click install missing nodes.

That's extremely long! Is this on your first run or everytime? The first time you run the workflow it will download the florence 2 model which might contribute to the lengthy time you're experiencing. Another idea might be that you're running out of VRAM or RAM and the models have to load and offload during the generation which will cause gen times to spike.

Any idea why it takes 3500 seconds to upscale, with a 4080 Super and an image of 700x700 upscaled by 1.0??

Hi Lewis, happy to help! The Simple String node is a part of this node pack: https://github.com/chrisgoringe/cg-use-everywhere If it doesn't show up automatically in the missing nodes manager, you can manually install it by using the "Install Via Git URL" button and pasting in the github link. Or you can git clone the repo and install dependencies. If you need more help, you can link your Patreon and Discord account to get access to the priority-support channel on Discord (let's you send screenshots) or send me a DM.
