There are 4 variants of Facebook video creation: 1 - Create a unique standout video yourself
. Get a physical product from your supplier or find the same product on Amazon (the 2nd variant is suitable for those who live in the US, as you may get the product fast). Film a video yourself. Your content will be unique. 2 - Ask your supplier to send you a video
and tell that you plan to increase sales volume if you really plan it. Then you may use video editors, for instance, those which are mentioned below. 3 - Use fee-paying sources with ready videos
for Facebook video ads and product ideas. As a rule, the services also offer detailed Facebook targeting and ad texts: 4 - Some people also find ready videos with high engagement on Facebook
and use them. For those who think how to get videos from Facebook, there are free online downloaders
. I can't recommend this variant, especially if videos are copyrighted. This variant is unethical and not safe.
