What is causing this sound? https://vimeo.com/270962821?utm_source=email&amp;utm_medium=vimeo-cliptranscode-201504&amp;utm_campaign=28749

Guys at the bike shop recommended a bottom bracket change would fix the problem however it didn't. Do I need to change the crankset? Click sounds only appears when I pedal with my right side between 12 to 3 o'clock angle.

Thanks!

Note: if I pedal only on my left pedal, there will be no clicking sound.
I think you kinda answered your own question. If the noise appears only when force applied to the right pedal, it's almost certainly that pedal. Especially as you changed the BB already. 

Check for play between the pedal and the crank. Turn the pedal and see if you can feel a 'hitch' or click. 

Most bikes shops have a pile of old pedals (especially cheap platforms that come with new higher end bikes that get swapped out for clipless pedals). Ask if they will swap out your pedals for a set that are know to work OK as a test. If the click goes away - bingo. I'd ask them for a bit if a deal on replacing the pedals as they mis-diagnosed the problem first time around.
