What is the best format for a video file to upscale?
Uncompressed video formats like AVI or MOV tend to yield the best results when upscaling, as they retain more original image data compared to compressed formats like MP4 or MKV.
High-bitrate H.264 or HEVC (H.265) encoded videos often upscale better than low-bitrate compressed files, as they have fewer compression artifacts to amplify during the upscaling process.
Lossless video codecs like ProRes or DNxHR are ideal for upscaling, as they preserve maximum image quality without any quality loss from compression.
Upscaling works best on videos recorded in 1080p or 2K resolution, as 4K and 8K source footage may not show significant visual improvements when enlarged further.
Older video formats like MPEG-2 and VC-1 tend to have more compression issues that can lead to poor upscaling quality compared to modern codecs.
Footage shot at higher frame rates like 60fps or 120fps generally upscales better than 24fps or 30fps videos, preserving more detailed motion.
Raw camera video files, while large, can provide the best starting point for upscaling as they have the least compression artifacts.
Upscaling works best on videos with clear, well-lit subjects and minimal noise or grain in the original footage.
AI-powered upscaling tools like Topaz Video Enhance AI can recover more detail and sharpness compared to traditional bicubic or Lanczos upscaling algorithms.
Combining multiple upscaling passes (e.g.
2K to 4K, then 4K to 8K) often leads to diminishing returns and increased visual artifacts.
Deinterlacing interlaced video footage before upscaling can improve the final quality by removing unwanted line patterns.
Enabling noise reduction and film grain restoration features in upscaling software can help offset quality loss from enlarging low-resolution videos.
Upscaling works best on videos with a simple, static background, as complex patterns and motion can be harder for AI to accurately reconstruct.
Ultimately, the "best" video format for upscaling depends on the specific footage, the desired output resolution, and the capabilities of the upscaling tool being used.
