Get the highest-quality source file available
Use a video upscaling tool or editor with AI super-resolution or high-quality scaling
Set the output resolution to 1920×1080
Choose a high-quality scaling algorithm such as Lanczos, Bicubic, or AI-based upscaling
Increase bitrate for the export to preserve detail
Enable noise reduction before upscaling if the source is noisy
Apply deinterlacing if the original video is interlaced
Correct color, contrast, and sharpness before final export
Use frame interpolation only if you need smoother motion
Export in a high-quality codec such as H.264, H.265, or ProRes
Keep the aspect ratio unchanged to avoid stretching
Review the upscaled video for artifacts, blur, and ringing
Make small sharpening adjustments after upscaling if needed
Save the final file in 1080p format
