Sagat Kara cancel combo issues

Hi all,

So im trying to do the following v trigger combo go to this video from Vesperarcade and start @ 8:02.

Im doing the same initial combo as he is doing up until i need to kara cancel Uppercut which i always seem to miss no deep uppercut finish. And yes im doing the Kara cancel with the HK version (forward HK and not the forward MK). Is there a point i can cancel straight into kara uppercut after the last kick of the trigger? I tried but he just stands there moving a bit thats all…im pretty sure im doing something wrong but what?

Thanks in advance
