just saw sophia burns is having a massive 75 percent off sale on her manyvids page. so i downloaded a much-coveted video that i had been eyeing for half a year for 9 dollars. its original price was 40 plus dollars. the problem is both the original and compressed download options are over 8gb! clearly the compressed version is not compressed as is sometimes the case with manyvids. its a 60 minute video in 4k. i dont really need that high quality of content and surely not that large of a file. any program or trick i can use on my pc to compress it to a say half the size while still retaining good quality and a playable file?
