Megapixel Extreme Upscale

This workflow is a “million-pixel” super upscaling pipeline built around SeedVR2 plus a tile-and-assemble stage. It first reads your image, gets its original width/height, and uses simple scaling/resizing nodes to push the image up (there are multiple ImageScaleBy / ImageResize+ steps), then computes a good tile size with TTP_Tile_image_size , splits the image into overlapping tiles with TTP_Image_Tile_Batch , and later reassembles them with TTP_Image_Assy —this is how it keeps memory stable and avoids seams when going extremely high resolution. The actual “quality jump” happens in SeedVR2VideoUpscaler : it takes the prepared image plus the loaded SeedVR2 DiT model and SeedVR2 VAE (both explicitly loaded in the graph), then reconstructs higher-detail tiles that you finally stitch back into a single huge image, preview, and compare A/B against the original with an Image Comparer before saving. In short: resize → tile → SeedVR2 upscale → assemble → compare/save, which is why you can push to ultra-high pixel counts without your GPU exploding. 🎥 YouTube Video Tutorial Want to know what this workflow actually does and how to start fast?
