bamjus - What toy do you use again?
Check the delay number that shows in player tab main screen in haptics connect app - you will want to match that number as your delay (its usually not a big difference for non Handy toys)
Its good if not better to physically watch the toy moving with the video eyeballing it as @justsomedude101 says above, but either way, a proper sync delay makes a world of difference thats for sure
Handy will definitely need to adjust the Handy delay setting to around -50ms if you live in EU side of the world, and -150ms if you live in North America side of the world
