Are you using videos on your social media? Well if you are then great but it's time to go back 20 years in time as we're back watching videos in 4:3 format, yep just like the good days.
If you're filming in 16:9 still, don't panic just add two black or colour bars on the top or bottom and add some text too and make it a square video.
Taking it a step further, why not try some videos in 9:16 (portrait). You would have seen these used on snapchat, facebook and instagram stories but are also great when shared to your feed too.
