How to Upscale Anime Video While Preserving Lines
What to check when upscaling anime: contours, flat colors, textures, and motion flicker.
Test lines and small text
Choose a scene with hair, thin contours, and subtitles. Check halos and line shimmer frame by frame.
Do not confuse sharpness with detail
Over-sharpening can create double contours and noise around text. Compare against the source at the same viewing scale.
When local control matters
Cloud processing is convenient for a quick test. Local Topaz can fit a large episode batch where repeatable settings matter.
