You can make some pretty awesome videos with Canva. You can also upload your own video footage and add them in as a page.
Animate it, add some elements, add some music and that’s it!
I find those types of videos do better on FB/IG versus a cinematic and professional edit. My experience at least.
I usually test both static and video ads within an ad set. Generally speaking, I find for bottom of funnel purchase campaigns, static ads tend to do better on average.
Videos are great for top of funnel and creating something more worth engaging with which builds up your video views audience and you can retarget them from there.
