Are the standards of video quality for the general consumer really high or something? I found a 4-minute long, 480p video on WhatsApp that is 66 MB LARGE

Why does it have to be this large? 2 Mb/s is overkill for a 640×480 video, even for H264 which is already efficient enough

I understand that quality if it’s from a camera, but video that’s meant to be shared on a general basis like in WA doesn’t need bitrate that large. Especially when it’s in 480p anyway…
