How to Choose the Best Free AI Video Upscaler ?
Choosing the right free AI video upscaler for you will depend on a few different factors:
Purpose: If you just need something quick and online for occasional use, then CapCut or TensorPix are both great options simply by virtue of their usability. If you are a more technical user, Video2X provides the option for more customization, but it does require set-up.
Quality Requirements: If you intend to put a lot of emphasis on the output quality for a professional project or high-stakes project, expect to see solid quality using Topaz Labs and TensorPix as they have provided the best results up to 4K quality. For general use, CapCut will be just fine.
More Features: If you also want features like stabilization, denoising or even just more features such as an editor, seek out platforms that hyper-focus on AI video upscaling such as TensorPix or CapCut, which have a lot of extra features.
Ease of Use: For those who are just looking to avoid software installation altogether, purely online tools like CapCut or TensorPix are probably your best bet. However, if you’re comfortable downloading something then you can use Video2X, and they do have some benefits by it being open source.
Cost Considerations: Since all these will have free options, cost is not an issue from an onset, but think about how much you would be comfortable paying if you think you will eventually upgrade or use upgrades to access more features or a higher round of usage limits.
Advice on Using Free AI Video Upscalers Effectively !
To make the most out of free AI video upscalers, follow these best practices:
Select Your Initial Resolution: Upscaling too far is likely to lead to poor quality. A video upscaled from 360p to 4K is unlikely to give great or even usable results. Instead, strive for more reasonable increases, such as 720p to 1080p.
Minimize the Number of Upscales: Excessively upscaling the video will sometimes destroy video quality. Avoid using the tool like a madman, while testing the tool, try different settings to produce the best quality output without degrading the video quality.
Try Many Tools: Free Versions of many tools are readily available. So have fun trying different AI video upscalers to determine which one delivers the best results for your video, especially for more specialized or niche use cases such as anime or old footage.
Use the Upscaled Video Together with Other Tools: It is possible to further improve your video content even after it is upscaled by using normal video editing software to mix content such as applying effects, adding music or correcting colours.
Always Keep a Backup of Original Files: It is always good idea to keep a original copy of the video, because upscaling is a one way process, which you can’t revert. Having the original copy allows you to retry the upscaling process with different settings if you would like.
