This is the follow-up video to my previous "What does Video Sound like?" The signal works, but has an interesting pattern on the screen. Rather than showing the original signal, it shows a series of black and white flickers.
Are you referring to The black screen portions? The audio recording is at 44.1khz, which is well below the 4.5Mhz signal, and I posted this completely aware of the blackouts onscreen. I do suspect that it is due to the fact that the volume of my laptop was still set at 60% instead of 100%.
