What I want to know is how on earth did they make the page 58.7 MB. This can't be.


I can't quite believe my own arithmetic but... that would mean the page is larger than 30 minutes of video streamed using the new codec. Can that possibly be correct?

Calculations here, someone please tell me I'm wrong:

The caption quotes "30kbps", but that has to be a typo - I think they mean 30KBps (240kbps).

58.7MB * 1024 = 60,018KB 60,018KB / 30KB/s = 2000 seconds 2000s / 60 = 33 minutes


I don't think the codec uses 30kbps by default, that specific example is showing what it would look like at 30kbps. Obviously if you have the speed for it, it'll probably raise the bitrate more. Duo is known for adaptively scaling up and down and smoothly switching between different network conditions.


There are four large .gif files. I believe the one you are referring to is 2.6 MB and named `Duo_540X540_TransparentBG_3s_splitscreen_05.gif`, with a split screen comparison of what it would look like at 30kbps. The overhead is the graphics of the "montage", I figure.


I find a better way of inducing horror when it comes to page sizes is referring to “multiples of Doom” rather than megabytes. The original Doom shareware release was two 1.44MB floppies, so this page is 20.4 Dooms big.


I thought that had to be a typo. Good lord, why are they shipping videos as gifs?


There are only two ways of realistically demonstrating encoding artifacts: decode the actual format client side or transmit a lossless encoding. GIF surely isn't lossless, but its losses are somewhat orthogonal to those of the encodings in question. Still, yet could have done with much less of the same.


I think their blogs are still based off Blogger which hasn't been updated in quite some time. (which they own so they could fix themsleves..)


If it's stupid but it works, it's still stupid.


But it works.

If it's clever and it doesn't work, it's surely clever ... but it doesn't work


It has been known and well understood for many years now that you should use video (like mp4 or webm) in place of gifs if you want to save bandwidth.


would encoding your AV1 encoding demo with another encode produce the desired effects?
