Everyone who is verified for lens creators or just really good at it, i've noticed that they have their face or their own video from snapchat (with them using the filter and putting their username on it, you can tell its from snapchat because of the fonts) for the lens preview but everytime i try to add my video, it's not working??
It tells me it needs to be "720 x 1280" and "9:16 ratio" (don't know what that means) but i don't know how to resize a video? I've tried imovie but that doesnt work, i've tried making a normal snapchat video, instagram video, even tried using a online website to resize it but it didn't work & still gave me error.
Please can someone tell me what software or app do i need to get for this to work & explain to me how to do it as it's really annoying me & upsetting me, thankyou!
