Positive Prompt

Cinematic live-action film frame of an adorable chubby British Shorthair cat standing upright on two hind legs in an open apartment window at night, carefully holding a spherical clear glass fishbowl filled with water and a swimming vibrant orange goldfish. Warm amber interior kitchen lighting glowing through the window, contrasting dramatically against the dark cool navy facade of a multi-story city apartment building at night. Photorealistic, 35mm optical motion, sharp textures, high resolution movie still

Negative Prompt

unclothed, disrobed, lowres, blurry, bad anatomy, deformed paws, extra fingers, low quality, artifacts, watermark, text

Field Notes RTX 4070 Benchmark

Benchmark: NVIDIA GeForce RTX 4070 (237s execution, 1440x2560 @ 24fps, 1.01 fps)

1. Local Patch LaMa Inpainting Architecture: Watermark removal on AI-generated video cannot be treated as a brute-force global inpainting task without causing massive background temporal flicker. We isolate a tight 256x256 bounding box [450:706, 1024:1280] centered over the bottom-right watermark, execute SimpleLama inference on the cropped patch, and paste the inpainted texture back before super-resolution. 2. TensorRT 11.4 True FP16 Super-Resolution: Upscaling 720x1280 up to native 2K (1440x2560) is powered by a serialized TensorRT 11.4 FP16 BSRGANx2 execution engine on an NVIDIA GeForce RTX 4070. By enforcing strict C-contiguous memory layout and direct NVENC streaming, the pipeline maintains ~1.01 fps sustained throughput (237s for 240 frames) without VRAM paging. 3. Audio Remuxing and Edge Delivery: Audio tracks are preserved losslessly via two-pass FFmpeg muxing, moving the moov atom to the front (+faststart) for instant zero-buffering HTTP range streaming on Cloudflare Workers edge nodes.

Frequently Asked Questions FAQ

What GPU and VRAM are required to run Midnight Heist: Cat with Goldfish in a Bowl 2K Video?

This workflow requires a minimum of 12GB VRAM (recommended 12GB VRAM). Tested and verified on NVIDIA GeForce RTX 4070 (12GB VRAM) at 1440x2560 resolution.

How do I resolve missing custom nodes for this workflow?

You can drop the workflow JSON into our client-side Missing Node Auto-Resolver at https://decomfy.com/resolve/ to detect missing nodes and generate install commands, or run the 1-click terminal setup script provided below.

Is this full video generation or a 2K restoration pipeline?

This is strictly a 2K post-processing restoration pipeline on consumer RTX 4070 (12GB VRAM), not a full text-to-video generation model. The base video was generated externally via Google Gemini / Veo; the RTX 4070 executes patch LaMa inpainting to erase the watermark and serialized TensorRT 11.4 True FP16 BSRGANx2 to upscale to 1440x2560 @ 24fps.
