I too had trouble with this for a long time. It’s just practice and you’ll get it. You can go on Youtube and see people doing the trials, they also have a camera which tracks the hand movements. Although this didn’t help me. You just need to get the rhythm going. I found that it is basically a set timing.
Keep practising is all I can say. Nothing helped me except that.
@Reisen Yeah I’ve been watching his tutorials for the trials. Great stuff.
Thanks for the advice and video. I’m gonna try it when I get off of work tonight.
And if I understand it correctly, I should be pushing the button the moment after the normal hits? Like during the normal, I do the directional motions and when the normal hits I should push the punch soon after?
@Phil Rhythm has never been my strong suit haha.
I suck, but I’m slowly getting better.
If you want you can add me if you play on xbox.
I get fucked over in endless battles and I don’t think they are doing me any good so I’m always looking for players on my level to play with.
Gamertag: Mepha.
That goes out to any other scrubs like me too 
Basically, cancelling normal moves into specials requires no timing at all, just one simple rule; as fast as you can. Slow enough that you actually hit with the normal, but fast enough to leave no frame gap afterwards.
So if you cancel a Cr MK to a Hadouken you want to do the Hadouken right after you’ve imputed the Cr MK. You will already be in a down position so it’s just a rolling motion.
Yeah thanks guys. Found out from the vid Reisen posted. Has to be fast as junk like Larthy said.
