Video experts often credit 24fps with a more “cinematic” look, while 30fps is more common, especially for videos that need to be projected or broadcasted. A good rule of thumb is to ask the end user of your video what his or her preferences are and shoot based on that. Then, be sure your resolution is at least 1920 x 1080 to maintain quality footage.
However, in a social media context, video marketers must remember that people share emotions, not facts. 76% of users say they would share a branded video with their friends if it was entertaining. So create fun entertaining videos to encourage social shares. Emotions are not exactly ROI but social shares can increase traffic to your site, and you can take it from there.
