Frequently Asked Questions
Should I upscale or downscale?
Downscaling (4K→1080p) reduces file size. Upscaling (720p→1080p) does not improve quality.
What resolution is best for YouTube?
1080p (1920×1080) for standard HD. 4K (3840×2160) if you have the bandwidth and source quality.
Will changing resolution reduce quality?
Downscaling preserves quality well. Upscaling makes the video larger but does not add detail.
How much smaller is 1080p vs 4K?
Roughly 1/4 the file size. 4K has 4× the pixels of 1080p.
