VIDEO UPSCALER FAQ Common questions about video upscaling and enhancement Straightforward answers about quality, privacy, supported videos, and the difference between cloud enhancement and browser previews. What does an AI video upscaler and video enhancer do? An AI video upscaler enlarges a video while a video enhancer improves visible clarity and detail. This tool combines both: choose 2x or 4x enlargement and use High Quality cloud AI for the strongest enhancement. Which model gives the best video quality? High Quality Cloud is the recommended model for the best result. It uses more advanced AI processing than the browser previews, so it takes longer and uses credits, but it provides the highest available quality. Is Anime Preview the final result? No. They are fast, convenient previews that run in your browser and help you test a video without signing in. For a more detailed final result, choose High Quality Cloud. Is my video uploaded when I use a browser preview? No. Anime Preview runs on your device, so the source video is not uploaded. High Quality Cloud uploads the video securely because the enhancement is completed online. Which video files can I upscale? You can upload an MP4 video up to 500 MB and 30 minutes long. You can also trim the video before enhancement if you only need a shorter section. Should I choose 2x or 4x video upscaling? Choose 2x for a moderate size increase and 4x when you need a much larger video. The best choice depends on the original resolution and where you plan to watch or share the result.
