:{{w|Log_profile|LOG}} is also a video format, though I don't understand this well enough to discern whether this might be part of the joke or an unintentional coincidence.[[Special:Contributions/172.70.86.80|172.70.86.80]] 09:59, 23 January 2024 (UTC)

::It's not rendered in capitals, it's just "log." In log video formats, the logarithm of the pixel values is recorded, rather than the actual value. This results in a better match between the dynamic range of the camera and what is being recorded, so you get better precision in the values where it counts, and less precision where it doesn't. E.g. in an 8-bit linear scale, you have to round values between 3 and 4, because you can only record integers from 0 to 256. But in a made-up hypothetical 8-bit log scale where you take the base 10 log and multiply by some k (here let's say k=106.3, which is 256/log(256)), you could record your 3 as 51 (log(3)*k), 4 as 64, and you'd have everything from 51 to 63 to represent the values between 3 and 4 (e.g. 52 would be 3.08, 53 would be 3.15, 54 would be 3.22, etc.). The downside is that in exchange for that expansion at the low end, you'd to record both 224 and 225 as 250 (because they are 249.8 and 250.0), so you get dynamic range compression at the other end. It doesn't have much to do with this comic directly, because the the pixel values in this graph are either on (here grey rather than black) or off, no intermediate values.

: it's pretty common for videos to have flashbacks and scene changes. Graphing the electron beam for crt video would be pretty pretty straightforward, just wavy line(s) with pulses that mean go down one line and back the far "left."[[Special:Contributions/108.162.216.19|108.162.216.19]] 17:14, 23 January 2024 (UTC)

There seems to be a subtle relativity joke in the title text, with misalignments in both time and space being a reference to spacetime. {{unsigned ip|172.71.154.42|00:05, 23 January 2024}}
