25th frame effect

Hello Alexey! Monday 25 Sep 2000 00:44:33, Alexej Antipov -> Dmitriy Nesmachny: DN>>>> So why bother? Switch screen and that's it. But not DN>>>> it will work, I tried something similar (not 25th frame, but DN>>>> short-term switching of screens once per second by 1 DN>>>> frame is very noticeable with a contrasting image DN>>>> extreme DN>>>> least). DN>> The picture lasts 1/50 of a second, and the remaining 49/50 lasts DN>> main image. AA> Then this is the effect of not even the 25th, but the 50th frame. Are you sure AA> that is exactly how long he stayed on the screen since he was AA> was it very noticeable? Damn, can't you calm down? ;-))) I’ll throw the source code at you Alasme, experiment. Dedicated to all lovers of fairy tales about frame 25: ====Start #25KADR .C================== ORG #61A8 BEGIN JR $+2 ;TRIGGER SWITCH ON LD HL,INT_DSP ;25 FRAME MODE OH LD (#FEFF),HL D.I.

It is advisable to launch from BASIC, everything is on Internet. I can see the 25th frame perfectly. Best regards, Dmitriy.

Greetings, Valeriy! Wed 18 Oct 2000 at 20:51:30 Valeriy Kovalev and Dmitriy Nesmachny were talking on the topic of the effect of the 25th frame. VK> IMHO this is how it should be... Yes, all this nonsense with frame 25 is complete nonsense. The human eye, although it has a certain level of sensitivity, but is able to distinguish between frame 25 and frame 50 personnel scan. And it will be perceived as a simple flicker. Here's an example in BASIC: 10 print at 10,0;"Main text" 20 pause 49 30 print at 10.0;"25 frame" 40 pause 1 50 go to 10 No hypnosis. Everything is as simple as 2 kopecks. Happy, Valeriy! Vivid/Brainwave^X-Project was with you. [ZX] [Sailor Moon]
