Getting viewers to watch your video depends on the platform you are on. The best length for a video on Instagram is 30 seconds. For Twitter, it is 45 seconds. Facebook users will watch a little longer for up to a 1 minute recommended video length. On YouTube, viewers prefer videos that are 2 minutes long. The risk of creating videos that are longer than these times is that you may lose the viewer’s attention, and they will move on to the next post. If your video is shorter, you may not give as much information as the view would like.
“Video marketers know we lack patience. So they’re starting to tailor content for our dwindling attention spans. In fact, 56% of all videos published in the last year are less than 2 minutes long.”
