Understanding Video Compression: Quality vs. Size

Learn how modern video compression works

Video compression works by removing redundant information that the human eye can't perceive. Modern video codecs like H.264 and H.265 use sophisticated algorithms to maintain visual quality while dramatically reducing file sizes.

Key factors affecting compression:

ResolutionHigher resolutions (4K, 1080p) contain more data
BitrateThe amount of data used per second of video
Frame RateMore frames per second means larger files
Codec EfficiencyNewer codecs compress better than older formats

💡 Our video compressor optimizes all these factors automatically while giving you manual control when needed.
