The RTX Video HDR feature of Nvidia RTX graphics cards utilizes AI algorithms to automatically convert SDR content to HDR quality, without manual intervention. Compatible with RTX series graphics cards and HDR10 displays, it can be used in Microsoft Edge and Google Chrome browsers. It improves the depth of detail in old videos and enhances color rendering. The effect is even better when paired with high-end HDR monitors. Similar to the RTX Video Super-Resolution technology, it also uses AI to enhance picture quality. It's free, requiring only the latest Nvidia drivers and RTX graphics cards to be installed. Suitable for users who need to improve the quality of old videos.

FMA-Net is a deep learning model specialized in video super-resolution and deblurring. It is designed to restore videos of low resolution and blur into high resolution and clarity. The model achieves this through a combination of flow-guided dynamic filtering and iterative feature refinement using multi-attention techniques, which are effective in handling large motions within the video. This results in a joint super-resolution and deblurring of videos. The model boasts its simplicity in structure and notable effectiveness, making it suitable for wide application in video enhancement and editing fields.

Upscale-A-Video is a diffusion-based model designed to increase video resolution by taking low-resolution videos and text prompts as input. The model ensures temporal consistency through two key mechanisms: locally, it integrates temporal layers into the U-Net and VAE-Decoder to maintain consistency in short sequences; globally, it introduces a stream-guided recurrent potential propagation module that enhances overall video stability by propagating and fusing potential information throughout the sequence. Due to the diffusion paradigm, our model balances fidelity and quality by allowing text prompts to guide texture creation and tunable noise levels, thus achieving a trade-off between restoration and generation. Extensive experiments have proved that Upscale-A-Video outperforms existing methods across synthetic and real-world benchmarks as well as AI-generated videos, demonstrating impressive visual fidelity and temporal consistency.

Frame Interpolation (Frame Interpolation) is a high-quality frame interpolation neural network model. This model uses a unified single-network method, does not require additional pre-trained networks, such as optical flow or depth networks, but still achieves state-of-the-art results. The model uses a multi-scale feature extractor to share the same convolutional weights at different scales. The model is trained only using frame trios.
