Hey Steven!
I’m really happy to hear you’re liking them. I will make some tutorials, but for now — you use an effect called ‘track matte key’ on your footage layer that allows you to choose the imported 360 360 matte as your transition. You’ll want to set it to luma matte, and you can also invert it to use white/black as your positive image.
Let me know if that works out for you! If you have any requests for transition styles, let me know and I’ll add them to the pack!
Thanks,
Jesse
