i own a mac. i want to convert an mp4 to a webm.
i look up free webm converters. the one i normally use, cloudconvert, only allows 5 minutes of free conversion time per unregistered account.
i register an account. "garfieldfromgarfield", i type in. this will solve the problem.
wrong. even with an account, i am still limited to a measly 5 minutes of conversion time per file. a pittance.
i find another video converter site. this one has no time restrictions. great! i convert the video and open it. the quality is abysmal. i cannot upload this.
i try another. better, but only slightly. i'm a little frustrated.
i ask the internet. there must be an alternative. surely there are hundreds if not thousands of people like me who have the same problem.
let's try freemake, that sounds good. but i can't, as it's only for windows.
mairo suggests ffmpeg. let's try that. but i cannot figure out how to use it. i cannot code. i trash the program in resignation.
please help.

@garfieldfromgarfield:
Use FFmpeg and you don't have to pay anything or register to dubious websites:

$ ffmpeg -hide_banner -i ./somevideo.mp4 -c:v libvpx-vp9 -b:v 0 -crf 30 -pass 1 -an -f null /dev/null && \
ffmpeg -hide_banner -i ./somevideo.mp4 -c:v libvpx-vp9 -b:v 0 -crf 30 -pass 2 -c:a libopus -b:a 128k -vbr on -compression_level 10 ./someothervideo.webm
