What do you currently have access to (Photoshop, Topaz, etc.)? Is the goal artistic restoration or forensic clarity ?
Enabling built-in deblocking (such as FFmpeg's pp or yadif filters) smooths out the sharp boundaries of compressed pixel blocks.
To combat this, professional workflows rely on non-destructive post-processing to reconstruct the missing data. Step 1: Choosing Your AI Upscaling Engine
Achieving an elite-tier render requires manually balancing your software settings rather than relying entirely on auto-features.
Use high-quality algorithms like NGU (Next Generation Upscaling) to intelligently reconstruct missing color data.
