Using a video on social media to pitch a product range can be far more effective that still photos. Experts disagree on time and other factors for videos. I have found that for most products I pitch, a video of between 15 and 30 seconds works best. It needs to be not over-produced. It needs to feel it is from you.
Here is an example of a video I used in a Facebook promotion recently, the engagement was terrific, including plenty of shares of the video. Purchases flowed as a result. It is simple, not produced. Those types of videos tend to work better in my experience.
