Getting high-quality video outputs often means juggling three constraints: speed, VRAM and control. While many artists ultimately want 4K quality, most prefer to generate smaller, faster previews first, and then upscale them. Today’s upscalers take minutes to upscale a 10‑second clip into 4K resolution.
Now, users can quickly upscale generated video to 4K with NVIDIA RTX Video Super Resolution, available as a node for ComfyUI. RTX Video can be accessed as a standalone node for building video workflows from scratch.
For AI developers, NVIDIA released a free Python package available via the PyPI repository , along with sample code on GitHub and a VFX Python bindings guide , to get started quickly. The package provides programmatic access to the same AI upscaling technology that powers RTX Video, running directly on RTX GPU Tensor Cores to deliver 4K upscaling 30x faster than alternative popular local upscalers, and at a fraction of the VRAM cost. The package is powered by the NVIDIA Video Effects software development kit .

💡 LTX Desktop is a fully local, open-source video editor running directly on the LTX engine, optimized for NVIDIA GPUs and compatible hardware.
🦥 LM Link connects separate devices running LM Studio, allowing models to run on remote machines as if they were local. It’s ideal for users wanting to run an agent on their laptop while still accessing free and private AI, powered by their DGX Spark or RTX desktop. Learn how to run LM Studio on DGX Spark .
🎮On Tuesday, March 31, as part of the next opt-in NVIDIA App beta, overrides for NVIDIA DLSS 4.5 Dynamic Multi Frame Generation and DLSS 4.5 Multi Frame Generation 6x Mode will be released for GeForce RTX 50 Series owners. Learn about NVIDIA news at GDC .
🤖Next month, a new NVIDIA RTX Remix update will introduce Advanced Particle VFX , enabling modders to create a wide array of particle effects that further improve image quality, detail and immersion.
🦄 Topaz Labs has collaborated with NVIDIA to optimize NeuroStream for NVIDIA GPUs — a proprietary VRAM optimization that allows complex AI models to run on consumer hardware.
📃 Microsoft has introduced support for VoiceMod, one of the first apps to enable Windows ML for GPU inference, significantly improving performance voice quality compared with CPUs.
