Solisyon an se konpresyon: yon metòd matematik nan "voye soti" done nesesè. konpresyon videyo diminye gwosè dosye pa voye soti done pou seksyon nan videyo a ki pa chanje soti nan ankadreman-a-ankadreman. Pou egzanp, si yon kwen nan videyo a se nwa pou 10 minit dwat, pi fò nan ke done aktyèl ka anlè ak ranplase ak yon referans tankou, "fè kwen sa a nwa pou ankadreman yo 300 kap vini an."

The solution is compression: a mathematical method of “throwing out” unnecessary data. Video compression reduces file sizes by throwing out data for sections of the video that don’t change from frame-to-frame. For example, if a corner of the video is black for 10 minutes straight, most of that actual data can be tossed and replaced with a reference like, “make this corner black for the next 300 frames.”
