How to upscale video to 1080p with FFmpeg?

Use: ffmpeg -i input.mp4 -vf "scale=1920:-2:flags=lanczos" -c:v libx264 -crf 20 output.mp4. Keeps aspect, sharpens edges.

Best FFmpeg filter for video noise removal?

hqdn3d=4:3:6:4.5 starts gentle. Ramp luma_temporal for heavy grain — preview frames first.

Two passes: vidstabdetect generates .trf, then vidstabtransform applies. Zoom=1, smoothing=10 for starters.
