Infinite doesn't only manage to dance in 2x speed flawlessly, but they're still perfectly synchronized as well. :D

Infinite nails it! I got goosebumps the first time I watched Be Mine 2x. Every angle is perfect! It seems normal to them.

As expected Infinite! GOT7 was really impressive too considering how hard the choreo is.

MYUNGSOO'S IMAGINARY MIC & DONGWOO'S RAP! MAN! I'M SO PROUD OF MY BOYS! 99.9% SYNC! PROUD TO BE INSPIRIT HERE!

Every group Did fabulous job. It's not a joke to perform dance in double speed. I appreciate all of them . Last performance of INFINITE was jaw breaking...... PERFECT

Got7 slayed like damn is it even possible to do that dance at 2x speed.. they are amazing

Infinite got the dance as well as sync .. 인피니트 !! 😍💖

Just look at how diferent and unique INFINITE are, from their style to the choreography they've found the sound that fits no one but them!!!

the exhibition part of infinite makes me speechless!! daebak!! 99.99% synchronization!!

Got7's dance already seems to be 2x speed! This is like the speed of light version.

Infinite! The Kings! Everything is so flawless and clean. Good to see

infiniteeeeeeeeeeeeeee....... they are the best among all the groups that dances their own song correctly and in syncronized even twice the speed of the real song. they even manage to lip sync it even it is faster than usual and also they also manage to smile while dancing .... no doubt they are the best oppa for me... infinite forever fighting

infinite is like kings.. got7 is good too.. but infinite synchronization is the best.. and even our grandpa gyu did it.. :D

Infinite performed "Be Mine" 2x Version perfectly even it was released 5 freaking years ago. 😎

INFINITE ARE KPOP KINGS THAT IS IT NO WORDS ARE NEEDED TO EXPLAIN HOW PERFECT THEIR DANCE IS 💕💕💕💕💕💕💕💕💕💕

It seems I will never run out of reasons to call myself a proud Inspirit!♡

infinite! so crazy! i guess it's a piece of cake for hoya by looking at his expression hahahha

I watched all but Infinite still the best to me. Their leg angles still perfect at the chorus, Dongwoo rapping in 2x speed, and the amazing dance break ^^

GOT7 deserve the title "King Of 2X Dance". Their performance amazed me so much. Just like G-Friend's.

Infinite totally slayed it!!! 100% HEART!!!!!!!!!!

i swear not even a fan of infinite but nobody can beat the best sync dance of infinite even 2x faster

infinite slayyyy ♡♡♡ they are kings of dance ♡

You just can't beat Infinite...they're always flawless....even our precious Sunggyu :)

You can tell why INFINITE are kings of dance!!

Infinite!!! Infinite!!! Infinite!!! omggggg

everyone did their best and all of them are good. But for me infinite is amazing...

myungsoo and his loyalty towards his invisible mic ㅋㅋ

INFINITE is the Kings imo because all members didn't lose their tempo & their group amazingly in-synched, solid formation.

INFINITE even they "the oldest" here, but they did the best between those group. so proud

btob was so funny 💕😂

Infinite my babies!!!! Have I mentioned that I'm super proud to be an inspirit? I'm an aghase and melody too and both got7 and btob also did really well but no one can beat infinite when it comes to 100% sychronisation.

Ok infinite killed that PERFECTLY IVE NEVER SEEN IT DONE SO PERFECT ABD SYNCHRONIZED

now im going to stan infinite for that wonderful dance 😄😄

Infinite killed it like really really

i can't believe that infinite said the eye was their hardest choreography. i can't even do the intro of any of their slow songs properly 😂

INFINITE are the grandpas of this video but they still slayed lol hahahaha

infinite!!! wow!!

INFINITE FTWWWWWWW

Dongwoo sure enjoyed the 2x version

INFINITE son perfectos en el x2

*OMO GOT7 HARD CARRY IS NEW SONG, AND THEY ALREADY KILL IT WITH 2X SPEED, THAT SO HARD,AND TIRED!! THEY DO PERFECTLY!!, AND,IF YOU DO SO FUCKING HARD FOOTWORK!!*

INFINITE ARE THE BEST! THE BEST!

they all were good but INFINITE were amazinggggg ! why they are so perfect like this??

BTOB's crazy foot work reminds me Teentop's song Rocking.

INFINITE!!! #InfiniteOnly

infinite are the best because they are perfect though they are older compared got7, BtoB and twice 😊👍

You'll know infinite is in sync when you pause it and they all have the same pose

Infinite slayyyyyys! Now Im waiting for SHINee to do the Sherlock 2x speed.

infinite slayed

INFINITE SLAYS!

The GOT7 one left me breathless. Just how fast was that omg???

I'm overwhelmed that a lot of comments here are praises about Infinite. Thank you for that. All the groups did great, btw.

GOSH SO MANY PPL ASKING FOR THE BLONDE GUY IN THE LAST PART WHICH IS INFINITE HAHA HE'S SUNGJONG EVERYONE! INFINITE'S MAKNAE! :D

Everybody's just commenting about Infinite, when I'm here thinking that GOT7 did an amazingly great job, since the beat was so fast

infinite was the best thus far....compare to others...

infinite is perfect among them all..

infinite u r the best ❤❤❤❤😙😙😙😍😍😍😘😘

infinite is the bestt !! 💓💞💞

INFINITE = SINCRONIZACION ♡♡♡

Tanginaaa ang galing ng INFINITE!!!!!!!!!! IM SO PROUD OF MY BOYS

I give synchronization kings title to Infinite. But to be fair, this IS a 2X challenge and honestly speaking BToB and GOT7 got the harder choreography so they did extremely well for that. If you don't believe me try moving your arms and legs with them and you'll see which moves require more energy. 2X challenge winner for me personally is therefore GOT7

got7 the kings of 2x speed dance.! no doubt they are slaying. 😊☺

Infinite are the best when it comes to 2x speed. kekeke

omg INFINITE

infinite 😁😁😁

Infinite!

infinite wins this that why there the kings of sync 99.99% of kpop since 2010

Infinite slays it again. 😍😍😍 Fighting!!!!

got7 just slayed my existence woooow I can't even get out of my bed without getting a cramp 😂 infinite was pretty good too 😮

*OMG GOT7 just slayed their performance... They're so amazing ❤ **#GOT7hwaiting*

I can't do Hard Carry at HALF speed nevermind twice the speed

*still waiting for BTS to do a full 2x dance on Weekly Idol*

INFINITE SLAYS

GOT7 absolutely SLAYED!!! They set the stage on fire, literally ripped it apart. Wow, just wow. *applause*

Obviously infinite was the best but I gotta give it up to btob cuz that footwork in wow is ridiculous in 2x speed.

인피니트 Why so Perfect Honeys☺️💓💓💓💗 INFINITE IS REAL

Still can't believe that Infinite's leader got the award of "It's your song then why can't you dance on it" for 3 times in a row on Weekly Idol!😂😂😂 I mean...just look at them SLAY!!!😎😎😎

GOT7's dance tho I'm proud to stan them stan GOT7 stan talent

OMG!!GOT7 really incredible..Hard Carry's cheography already fast and then 2x speed ...they are amazing!!

infinite = perfection

So proud for my only infinite. Always proud e an inspirit.

The legendary 'be mine' slayyyyy by INFINITE these guys aren't called INFINITE for no reason dayum.

When u are not the one dancing but u can already feel a heart attack approaching

I liked got7 the best, but I also feel like twice did a good job because doing that song with 9 people was amazing. however got7's new song hard carry was already really fast so doing at 2x speed is pure talent.

Love infinite so much...Be mine is their old song..2013 but they still can dance it perfectly without looking tired..they even smile and dongwoo live rap...omg

Imagine Shinee's Lucifer

JB always looks so hot. My biases will always be the JJ project XD

gfriend for girl , infinite for boy

thumbs up for infinite!!!!

Why the hell is my heart racing when they dance. 😂😂😭😭❤️

infiniteeeeeeeee

wow infinite was amazing

INFINITE WINS BY A LONG SHOT!!! All their footworks and body formations were 100% perfect ‼️‼️‼️‼️.

Infinite Daebak !!! Master of synchronization

I love that when Ilhoon fell Hyunsik just laughed xD His smile is too cute >~< And Changsub only standing there doing nothing hahha xD Eunkwang's face xD I love BtoB so much xD Haha, my poor Youngjae xD When they danced Hard Carry it was so amazing! :D And Infinite's synchronisation is honestly no joke :D I just watched their episode earlier, they're so funny x3 I don't want to let out Twice but I honestly don't know their names except for Dahyun, Tzuyu and Jihyo xD But they were super cute while doing Cheer Up so fast! :3

I got goosebumps when Mark's part at 3:19 came like whooaaaaa...... and now what if bts does fire or dope or bst for 2x speed dance? deym boi.

got 7 waas just amazing in hard carry , so i think they deserve the best ×2speed dance

all are. good but infinite is the best ..

Infinite...always so synchronized...even in 2x..they don't even slag when they are almost dead. Apparently, they were singing along live too...respect man.
