The capabilities of recording equipment and media playback devices increase every year, and with them the demand for higher quality content from viewers. But that can you do about that old 720p video recorded years ago, that is now hopelessly outdated?录制设备和媒体播放设备的功能每年都在增加，随之而来的是观众对更高质量内容的需求。但是，您能对几年前录制的旧 720p 视频做些什么，现在已经无可救药地过时了吗？

One option is to use a video upscaler like Topaz Video AI. It can increase the resolution of low-quality videos, as well as repair various issues, without making the result blurry or stripping away important details. It is designed to be usable by anyone, with an intuitive feature set and helpful presets.一种选择是使用像 Topaz Video AI 这样的视频升频器。它可以提高低质量视频的分辨率，以及修复各种问题，而不会使结果模糊或剥离重要细节。它旨在供任何人使用，具有直观的功能集和有用的预设。

Increase video resolution and enhance the output提高视频分辨率并增强输出

• Let’s start with upscaling. This app relies on AI models, which are trained on countless upscaled videos. Unlike other similar software, Video AI doesn’t handle each frame as a separate image. Instead, it analyzes surrounding frames to ensure the results are accurate.让我们从放大开始。此应用程序依赖于 AI 模型，这些模型在无数放大的视频上进行了训练。与其他类似软件不同，Video AI 不会将每一帧作为单独的图像处理。相反，它会分析周围的帧以确保结果准确。
• There are multiple upscaling models you can use, depending on the type of input video, its quality, and the various issues it may be plagued with. Once you’ve set a few basic parameters (video quality, type, and artifact type), the app recommends an AI model, which can be further customized.您可以使用多种放大模型，具体取决于输入视频的类型、质量以及它可能遇到的各种问题。设置了一些基本参数（视频质量、类型和工件类型）后，该应用程序会推荐一个 AI 模型，该模型可以进一步自定义。

Increase video frame rate and create slow-motion effects提高视频帧速率并创建慢动作效果

• Aside from boosting resolution, Video AI can also add new frames to create a smoother-looking video. It generates new frames using the Chronos AI model, which should provide better results than basic frame blending.除了提高分辨率外，Video AI 还可以添加新帧以创建看起来更流畅的视频。它使用 Chronos AI 模型生成新帧，这应该会提供比基本帧混合更好的结果。
• Since the app can add new frames, that means you also have the option of creating slow-motion effects. These rely on the same model, while also slowing down playback speed.由于该应用程序可以添加新帧，这意味着您还可以选择创建慢动作效果。这些依赖于相同的模型，同时也会减慢播放速度。

Excellent results — but might need some tinkering出色的结果 — 但可能需要一些修补

• The program is very easy to work with, and the suggested models tend to be suitable, but not always. It’s generally a good idea to try out multiple models to see which provides the best results. This can be particularly tricky when trying to increase resolution while preserving fine details that blend in with compression artifacts, but I was always able to get a better-looking video in the end.该程序非常易于使用，建议的模型往往是合适的，但并非总是如此。通常，最好尝试多个模型，看看哪个模型能提供最佳结果。当尝试提高分辨率同时保留与压缩伪影混合的精细细节时，这可能特别棘手，但我最终总能获得更好看的视频。
• It’s also good not to be overly optimistic. While the app can upscale videos to up to 8K, if you’re trying to process an old 480p clip, you’re asking for a lot.不要过于乐观也是好的。虽然该应用程序可以将视频升级到高达 8K，但如果您尝试处理旧的 480p 剪辑，那么您的要求很高。

Relatively fast processing and simple workflow处理速度相对较快，工作流程简单

• As far as rendering speed is concerned, video upscaling is always going to be a slow process. However, Video AI runs natively on Apple Silicon processors and can take full advantage of their far superior capabilities. If you’re on an older Intel Mac, however, you’re going to have a lot of waiting to do.就渲染速度而言，视频放大始终是一个缓慢的过程。但是，视频 AI 在 Apple Silicon 处理器上原生运行，可以充分利用其卓越的功能。但是，如果您使用的是较旧的 Intel Mac，您将有很多等待工作要做。
• All in all, Topaz Video AI is one of your best options for video upscaling at the moment. It can compete with any other app of its kind, and its intuitive design makes it an attractive option for non-professionals and those who rely on a straightforward workflow. It also supports batch processing, which is great if you have a bunch of smaller clips to go through.总而言之，Topaz Video AI 是目前视频升级的最佳选择之一。它可以与任何其他同类应用程序竞争，其直观的设计使其成为非专业人士和依赖简单工作流程的人的有吸引力的选择。它还支持批处理，如果您有一堆较小的剪辑要处理，这非常棒。
