In capturing this demo we did a special VGA 60hz build to avoid 70hz>60hz stutter. It's running from the VGA card into a top end Kramer scaler, 60hz into an Atomos Inferno onto SSD at 10bit (which does record YUV, but does RGB cross conversion in 10 bit space). We then doing a Lancos3 upscale from pixel quadrupled HD to optimally framed 4k at 60hz using the Grass Valley broadcast algos (which are very clean). We correct for RGB > YUV error in 10-bit, clamping the VGA's slightly-noisey black levels to float just above the "displayed" 0 YUV value (which is ironically converted back to RGB on your graphics card!) and set white levels to around level 1000 (10bit) because the VGA DAC actually floats around a bit (tends to overshoot early values). That gives us 24 values of white-level overshoot (according to the waveform scopes). Interestingly both cards I ran it on were slightly blue-tinted; both on video vector scope AND when RMS voltage from the VGA pins revealed this. So we left that weighting / look in the capture. It's subtle. Finally, H265 was set to max precision, took about an hour to render on a Ryzen 9 (using a software CODEC) then up to YouTube where it gets slightly downgraded with a lazy "optimised for speed" algo ... BUT, it's not bad. It's about as good as we could possibly do!
The passion for quality is clear here!
Also, what a great demo! - rulezadded on the 2023-12-18 11:20:27

- A demo that reminded me of the days where I'd need a SET BLASTER command set. Noice.

- Reminds me of when I was working at a datacenter in Slough. Slough is a miserable town, and the datacenters were the ultimate in liminal spaces. This nailed the aesthetic.

- Another demo where I failed to say how brilliant this one is!
One of my favourites. The Yolk soundtrack is an all time classic. - rulezadded on the 2023-09-16 22:12:18

- How could I forget to comment on this? An absolutely timeless production - absolutely iconic. The glitch work in the music was far ahead of its time when it was released, and the breaks soundtrack is an absolute bop.
