It's IMPOSSIBLE to Beat This Portal World Record. Here's Why... 

UPDATE: A change in In-Game timing occurred on the Portal Speedrun leaderboards, so all individual levels are 0.015 slower. This video is still accurate, just the perfect time is now 15.930 instead of 15.915.

MSushi is so good. He can make a 15 minute video about a 15 second speedrun and it’s entertaining and informative

I would actually have loved to see a 0:01 time for this chamber in the challenge maps section.

i love how confident you sound. it feels like you're setting yourself up to get memed on when this inevitably gets beaten

13:46 that trigger is a trigger_changelevel in every elevator that has a level transition! normally when the elevator passes a certain node in its path it sends an output to that trigger to load the next map in sequence, but *usually* those triggers have the "Disable Touch" flag set so that's the ONLY way they can be triggered. the dev who made this level forgot to set that flag on the chamber 10 elevator so it can be triggered by touch

cant wait to check back in a year and a half for this run to become faster

you can tell he is trying to jinx himself SO hard at the end

Msushi: No, actually, that would be imposibble. Because Chamber 14 is Portal's Perfect Speedrun. Entire Portal Speedrun Comunity: Well guys, we know what we are going to be doing today.

I wonder how GLaDOS would write this down in her report lol. "Due to an apparent anomaly with the Aperture Science Handheld Portal Device, the test subject was portaled into the chamber's exit elevator shaft. Test subject shall be praised for completing the test faster than any test subject on record, and shall be rewarded with a complimentary victory candescence."

4:50 i love the excited spazzing out. it's a wonderful expression of joy.

Never stop saying things like "a better strategy is pretty unlikely to be discovered" please, it makes the moments when those strategies are actually found feel all the more hype.

Ah yes 15min video about 3 second speedrun.

Msushi is one of those "click randomly at 3 am" content creators and I love it

a 55 way tie on the same millisecond is insane

This is the most portal thing to ever exist

What a great way to make everyone try as hard as possible to beat the record.

Msushi, how do you make the most entertaining and engaging videos about the strangest things? In all honesty great vid man.

I see the purple portal gun as the channel avatar, so whenever you explain something, I'm imagining a disembodied purple portal gun speaking to me.

The thing about speedrunners is that perfection is never enough. No serious dedicated speedrunner who calls him or her self a SPEEDRUNNER has ever said "I'm happy with this time, it cannot be beaten and I know I can't do any better". Every world record brings the question "But can I go faster?"

Nice video as always. You and Kronios were actually one of my main inspirations to pick up Portal again and learn some speedrun strats - I went from being able to beat the game in 45 minutes to being able to beat it in under 30!

00:25 - Until we find a new strategy*

This is portal speedrun, you never know what a PERFECT time is. Awesome video btw (as always). So goodluck on making videos and speedrunning. Stay Determined Msushi!

Wow this guy justs explains incredibly complicated speedrun strats perfectly

I really really enjoyed the Baba Is You background music.

you see, imagine there is a bus...

at 13:45, the reason for this debug trigger is that when the elevator is rising it touches this trigger, which will load the next map when the elevator finishes rising. The reason that this trigger can be triggered by a player is because on every other chamber there is a checkbox that makes it so that a player cannot trigger this except on chamber 10

The one thing that goes through my mind - I assume it's not faster to jump before entering the first portal, to gain more momentum going into the portal? I feel kind of silly asking that, because in my mind there is no way something that simple would be overlooked (Or, I just missed the jump to begin with, and it's in there) But then again, sillier improvements to speedruns have been made in the past, where a casual player asked just the right question

11:32 Sneaky Msushi in the leaderboards lol But seriously, thank you Portal youtuber+speedrunners (youtuberunners? speedtubers?) for shining light on these great achievements

msushi is the type of guy to make a 15 min video about 1 second (14 secs are not even important) gameplay

the clarity you bring to your subjects is beyond impressive!

im familiar with the edge glitch

I love Msushi AND Chamber 14

Always a good day when Msushi explains the wonderful world of Portal speedrunning.

11:35 YOOO COSINE THATS MY FRIEND SHES AWESOME!!!

The only thing I can think of is using saveloads to skip the cooldown (like how HL21 spams a ton of attacks into Nihilanth in a split second), but IL is single segment (no saves or loads) and I don't know if that's even a thing in Portal or not. Edit: "I know if that's a thing or not" → "I don't know if that's a thing or not"

Interesting stuff! Only thing I can think of is not doing the level as an IL run and bringing something from the previous level to insta-launch you directly into the elevator. That way, you don't need to fire any portals and are not limited to the gun's rate of fire.

not even tryna get likes it actually makes me cry seeing msushi upload, its such good content

Ahhh I cry happy tears every time you upload a new video, I love them so much

i read this as "portal's perfect chamber 14 speedrun is PERFECT, here's why"

I'm glad speedrunning this game was part of my childhood. Kinda getting more and more serial the more time goes on. great vid.

i love how at 5:12 the client name says, subscribe to msushi

Wow, I had 29:48 time in my portal "speedrun" (lol), and it's just marvelously for me to see the record speedruns.

Msushi i absolutely love your channel and i also love the portal games. You should try doing a portal stories Mel speedrun. I would absolutely love to watch it!

Thanks for the tutorial! I've just managed to do this level in 10 minutes!

It's a good day to be a chamber 14 IL fan.

The full spectrum of speedrunning, from DK64 100% to Portal chamber 14.

Msushi: "Chamber 14 is Portal's perfect speedrun" Speedrunners: "And I took that personally!" Counting down the days until this video has an update 😂

You're perfect

I love this channel, can't wait for new videos

really good video!! you always make bangers :)

Well made. good structuring, nice twists, guessing what I'm thinking is always a plus, engaging as well. no notes, 10/10

"[...] is perfect" Trackmania players: "Hold my thousandth"

It's not a problem of execution. The players have to find out how to skip the elevator ride at the start

The only way to change this WR seems to be to officially disallow the seam shot portals by saying they are out of bounds. Then the two portal with a hop into the elevator would go back to being the top method until someone could further reduce the movement

Awesome Video!

I could have sworn the portal fire speed was tied to each portal color separately and you could near instantly fire one after the other. Been years since I played though so I don’t doubt i’m misremembering

I hope someone reads this, but if he shot the first portal at the ground instead of the seam. He would go into the portal fast because he has to wait for the bottom portal to open up since it's right below him. So it should be that it starts simple like this. Door open, step forward shoot floor, step forward shoot seam step forward at the same time the edge of the bottom portal opens up. QPR and jump.

I just finished watching the whole video and it's so goated. I love msushi

Hey, I am not a Portal expert but some time ago I heard about a Portal TAS tool, is the chamber perfected even for tas? In the Trackmania TAS comunity there is a ''bruteforce'' system and I heard there is a half life TAS tool inspired by the Trackmania TAS bruteforce. Would it be possible for a Bruteforce TAS to be made in Portal, would that find maybe some unknown strategy, It did on Trackmania.

If there is one thing I've learned over the years, it's that nature abhors an "unbeatable" speedrun.

I saw that takodachi at 8:26! You can't fool me!

Watching this after completing portal 2 for the 2nd time really fun still

4:48 bro got so excited he started handing out free seizures 💀

0:35 "speedrunning is a part of most casual portal playthroughs, as if you want to get all of the achievements you're gonna have to get the gold speedrun medals" *shows image that says 97.7% of players did not get all of the achievements Great video. This part just cracked me up.

ok but they also said that max heat Hades was impossible...

I’ve never understood how the camera actually works in the oob route until this video. Just having the second camera brought it all together for me.

I loved this video already; let me explain; I got portal 1 and 2 in the companion collection on Nintendo switch. After beating portal 1 and 2, I was gonna do it again, and co op after with a friend, but all up to 100% completion. But after realizing I beat portal 1 on the wrong account I beat it again on the right account. Then I realized to get 100% I had to get cameras and radios, and I did that non consecutively, so 2 more times I beat it. Then I found out there was secret dialogue in chamber 19, so I beat it again, for the secret dialogue. Then, after beating all modes of all the still alive chambers, I was gonna beat all modes on the particular main story mode chambers. But then I saw that developers commentary existed. I beat portal 1’s main story line 6 times. I know all of the secrets. And I’m a long term msushi subscriber, so I loved how I got what he was talking about instantly. Keep up the good work, man!

Quite happy to have discovered the technique by myself when doing the challenges

its a good day when Msushi post a video

Question: why couldn't you shoot the first portal on the floor, which should be possible the very tick that the door opens, to shorten the time that the cooldown starts from until the next portal can be shot (through the corner peek)? It would be harder to line up, but it seems like it would mean the portals (and thus the cooldowns) can begin from an earlier time after the level loads by avoiding the time it takes to exit the elevator and crouch.

When we needed him most, he returned

I love speedrun history videos. The ones about tomb raider also highly entertaining

There are not many videos on youtube that make me actually think "wtf", but this is one of them 😂😂😂

New video ❤❤❤ i am so happy 😁

Awesome video

i’m so glad msushi made a video about the map i have the world record on

I will gladly take another Msushi video.

11:33 I'm in the video!!

I was a bit curious at the beggining, cuz you can jump and crouch before the level loads, but then i remembered, that it's impossible because of the way speedrun starts.

The only way to improve this run is a bit flip in the height of the elevator caused by a cosmic ray. But at that point, the elevator height could flip to the exact value right at the start, resulting in a 1 tick run.

2:29 I FIGURED THIS OUT WHEN I WAS LIKE TWELVE I FEEL GENIUS

-I'm surprised the idea of shooting the first portal earlier wasn't even entertained in this video. I'm sure there's some good reason it doesn't work, but it's not immediately obvious to me.- *EDIT:* From the comments, apparently there's a delay before you're allowed to fire the portal gun after loading the level. I didn't know this, so I think it would've been good to mention explicitly.

The tickrate isn't 1000 so you dont have three decimals of precision. Proof by exhaustion is impossible, due to the scale of the search space. You need go efficiently search it with like reinforcement learning and high exploration target.

I wasnt expecting to hear something from the Va-11 hall-a ost in one of your videos

This video changed my life

That music at the start triggered my PTSD.

i legit did not know how the chamber was meant to be done lol

2030: "And thanks to the recent shaboinky-bounce-clip the time this speedrun takes is cut in half."

It's usually after videos like this, it brings so much attention to the topic and the 'unbeatable' is beaten.

You know now that you made this video someone will find something in the next few weeks on pure coincidence lol.

I thought I was going crazy when I started hearing Running Hell playing in the background

I've actually never solved 14 the long way, haven't even seen some of those rooms

14:57 this will be a very funny soundbite in some future

5:07 finally for real somebody uses an apostrophe correctly (check subtitles)

Ah finally a portal video

just got the discord noti in the youtube tc 🙏🙏

bro its SUCH a good feeling when you upload

Alright, I'm just throwing crap at the wall and seeing if it sticks, my idea is that the most likely way to skip an elevator is to find a glitch that allows you to portal up it or clip up into the load zone preferably without an item but if needed it could still be a time save, or hopefully something with the menu, (think of the super meat boy calculation tab glitch) to skip it. I'm sure this idea has already been proposed or proven not to work but still, just wanted to get this out there.

beyond the heart jumpscare

"Maybe there's a faster route." Faster than teleporting directly into the ending elevator??
