Certain Speedruns once finished, even though could look simple (in certain occasions it actually could look blatantly hard), are of course was hard to do actually. Exactly Dino Crisis 2 Speedrun I've did, are took about a month to do it. Same as it is about other numerous Speedruns I've did, I was exhausted by the end of a day(s), and felt totally refreshed after lunch breaks, after which I was returning to Speedrun more (which usually about making repeated good like plays, eventually finally to get good like RNG, and thus in the end to get good like time). Due to fast nature of gameplay and tons of repeats and lots of time (time which due to fast nature of gameplay and tons of repeats, felt as if stretched even longer), I was totally exhausted mentally and physically, and I've felt really refreshed at lunch breaks. Speedrunning is mentally tough stuff to do actually, but it seems if you to use just a few hours per day to Speedrun, then like it's to be not much mentally challenging to play it and could be even enjoyable. But I've played it for days long, for over tens hours per day, and hell I do not re done it all at all once more even though my Dino Crisis 2 run was not accepted due to rules about which I to say more below.
'Now slightly digress and to do brief paragraph insertion, which relevant to Speedruns.' Twitch definitely look as insane vegetable harvesting, yet it do after all serve a purpose of verifying authentic valid runs. But, Twitch runs too are could be faked, and it just depends on putting investment of money and efforts put into it. Actually both, and amateur way fake, and professional way deep fake, could be done about it. From my amateur perspective, technology did quite a leap in recent decades, and what count, it all being free and accessible to public too. All windows overall which present on typical Twitch stream, are could be took from totally different unrelated occasions, video recordings, and times, regulated and altered, inserted rolled into one twitch look alike stream, put into video, and then played at stream. It all doable using basic free programs apps really. And about deep fake no need to go into it, as it is obvious it could be done too. Beside Twitch actually any other video live streaming platform look about same, including YouTube live stream too.
'Now back to Speedruns overall.' I mean while I've met on Speedrun certain Trump bribed freaks, however Dino Crisis 2 users seems was never among such. Thus even though my run was rejected, I accepted it as my own responsibility. And obviously fair enough I've not mentioned people of Dino Crisis 2 Speedrun, in rats I've did, and I do have mentioned in rats I've did other Speedrun freaks. Thus, even though my run was denied, rules being not the best, etc, yet it's fine really. And IGT of course could not serve as proof of authenticity of a run. I myself have seen certain IGT timer hacks in numerous games on several official online leaderboards (those online leaderboards IGT timer hacks seems sure thing was harder to do then in vid with fake run), and it just mean IGT timer are could be managed/manipulated by certain hacks, and it blatantly visible by impossible record time certain of which was as fast as few seconds. And TAS runs could be spotted by certain unusual behaviour of enemies, RNGs, etc. And if to talk about splicing up vids at black screen, it is require deep dive into it, and I've said it below under header 'Black screen'.
'Now finish up this section about Speedruns.' My Dino Crisis 2 run neither have hacked impossible IGT time, neither have unusuality of TAS run. IGT timer never could serve as proof of authenticity of a run. My Dino Crisis 2 and certain PSP emulator games like runs and vids are have exactly even and accurate time length of black screens according to original, which means I've not spliced it up really. My Xbox 360 runs used actual external camera recording of tv, which being among most obviously authentic runs. My Stronghold run got Radeon screen recorder timer and exactly even original sound throughout whole walkthrough, which serve as proof of authenticity of a run. And my Speedruns records are authentic and true really.
Much of games throughout whole walkthrough, could have certain moments with blackout/whiteout/redout/any other one toned complete screen, which making splicing up of videos and replacing it, possible and smooth looking. It being even more convenient with contemporary emulators, due to its simple accessibilty to use save states at any point of a game like. I myself have used it in game like Samurai Shodown few times for certain needed results, and before already slightly mentioned it in other website article. And I've said approximately such stuff:
'You could splice up video fragments without being easily spotted at black screens, in certain occasions. Whole vid (Samurai Shodown) is mostly authentic one chunk walkthrough, however, I've did few times splice up of vids for certain needed results. Even though spliced up black screens look smooth and uneasy to spot a transition replacement of those, however, it do being possible to spot it, or instead prove it wrong, in case of emulators. Because on emulators to get at save/load screen it takes time since have to pause the game like for it, and after it have to unpause it too and it takes even more of time. Those frames used of save/load screens as pause/unpause, are to make significant difference on timer and could be spotted by unusually short black screen time. Moreover, in certain games background sound from previous scene are could be hearable on black screen scene too, and it making it impossible the smooth unnoticetable edit splice up of such vids'.
It's approximately what I've said time ago, but actually exist a deeper dig of it. Although can measure time of black screens manually too, to spot it 100 percent accurately, need to use certain programs apps which could precisely calculate on micro seconds level the times of black screens. Once it done you to get black screen time of original authentic walkthroughs, and apply it to other black screen time of runs, and it must be precisely same (differences could occur based on platform, moment, emulator, etc, all of which obviously needed to be took into consideration appropriately once compared to its counterpart).
But then those black screens time could be extended too, thus it could be faked after all? Not exactly. Since could use extremely precise program app measurement of black screens. In case of fake and replaced black screens, it shows up by extremely precise measurements of black screen time.
But then could use same extremely precise program app time measurement, and create extremely precisely timed black screen? Moreover, by using similar extremely precise advanced tech, then could be done frame perfect editing of any game moment at all and splice it up, and not just at black screens? Nope. Frame perfect editing by replacement of any moment of game, if done good like are could be uneasy to spot, however, it seems quite spottable even visually by trained eye, and it definitely spottable by applying certain apps programs with ray tracing, colour palette swaps, etc, which making every game moment singular, and however smooth transition of 'perfect frame' could be, it would turns out jagged and visible by apps programs too. And as it is about black screen replacements, if indeed was done extremely precise time measurements adapted to original (which is uneasy to do and it require certain advanced programs apps), even then it could be spotted by even deeper and more precise time measurement system, which to exhibit replaced black screen of fake vid.
Then use multi billions dollars budget money and fame same as did it Gaga gang Taylor crew Diddies, use bribery corruption and conspired crews, use AI (which seems politicians/celebrities was using in news and their online posts etc, way before AI tech programs apps get publicly known available and widespread in use), use lies, use more of money and fame, use cheap garbage freaks, buy corrupt bribed conspired fraudulent freaks more, and then after all to get fake black screen by replacing it? No way, no ever. Since exist such as me and truth and Ultimate God presence in the world universe in form of time and death, Ghost art, and my website and YouTube accounts which are God mode, which totally destroyed them Gaga gang Taylor crew Diddies freaks. Because we, me, ghost, truth, time, death, and hell, are universal and eternal.
