It seems like a shame that they didn’t include a screenshot of the original (with natural grain), after suffering from low-bitrate streaming. Aka the actual baseline.

I can see why they want to compare against the actual local copy of the video with the natural grain. But that’s the perfect copy that they can’t actually hope to match.

Isn't that the image captioned "Regular AV1 (without FGS) @ 8274 kbps"?

I think I misread the figures.

But still, they have:

> A source video frame from They Cloned Tyrone

> Regular AV1 (without FGS) @ 8274 kbps

> AV1 with FGS @ 2804 kbps

Just to emphasize the problem, would it be nice to see:

Regular AV1 (without FGS) @ 2804 kbps

It should look really bad, right? Which would emphasize their results.

But why do they need to emphasize it even more than the examples they gave? The "AV1 with FGS @ 2804 kbps" already looks as good or better than the "AV1 (without FGS) @ 8274 kbps", so it'll definitely look better than AV1 without FGS at an even lower bandwidth.

I think the distinction here is, they provide the "regular" stream, and the FGS stream noting that it's much smaller yet looks similar. What they don't have is a lower-bandwidth "regular" one, what 2000-or-so kbps looks like without FGS.

They did.
