i think the flickering is just the different refresh rates of the screen and the recorder bumping against each other (so, yeah, no person should see that, unless they were also blinking crazy fast, and not in sync with the screen).RxBrad wrote: ↑Thu Jul 11, 2019 4:40 amHeh.. someone asked me to record the PWM dimming in slow motion. It's kind of neat. A lot like when you tried recording old CRT televisions.

Luckily, you don't notice the flickering in real life (at least I don't). Though it's at 146Hz, so there's a small possibility some people -- more likely some people's dogs -- might notice it.

Re: Button Suggestions for Mounting Inside Cartridge?
More specifically, wouldn't it just be the LCD's backlight switching on and off at the PWM frequency? The higher the duty cycle, the longer it stays on.
https://en.wikipedia.org/wiki/Pulse-wid ... Duty_cycle
So, the backlight turns on 146 times per second, and the higher the brightness / duty cycle, the longer it stays on every time it turns on. That's how the brightness actually changes.
At least that's my uneducated explanation.

Re: Button Suggestions for Mounting Inside Cartridge?
yeah that sounds more likely given that. either way, i think its essentially just a timing issue where the individual frame that the camera captures happens at the same time the screen (or backlight) is refreshing, and catches it briefly blank, but both would be happening too fast that human eyes wouldn't be able to notice it.RxBrad wrote: ↑Fri Jul 12, 2019 7:49 amMore specifically, wouldn't it just be the LCD's backlight switching on and off at the PWM frequency?
