linus tech tips Why the bitrate in newer LTT videos is so low?
The 1080p version of that painful pc build is 1920x960 30 fps - on my Firefox it defaults to AV1 and Opus audio :
The downloaded file is 1.78 GB (1,916,166,263 bytes) ... divided by 1700 seconds you get 1127156 bytes or 9,017,253 bits or 9017 kbps (which includes the 128 kbps).
Yeah, sure, it's not an accurate, the audio is vbr, there's mp4 overhead, whatever, it will be about the same percentage of overhead and audio mess on the other track.
The holographic frame video has same codec and resolution and uses 555 MB (582,871,670 bytes) for a total of 11:43 or 703 seconds so divide those and you get 829120 bytes per second or 6,632,963 bits or 6632 kbps
So the new video has much lower bitrate compared to the other.
Could be Youtube cuts costs with encoding and bandwidth during the virus by reducing bitrates.
Could also be other things like for example it wouldn't surprise me if Youtube starts videos with some lower bitrates and if the video becomes popular (as in 10 mil views for that video) they may do a re-encode at a higher bitrate.
