Promoting SFI through video is an important aspect of marketing or advertisement that one can undertake if we know how.
First of all, record your message or lines in a phone camera or camcorder in a clear flowing English with a very good background. You can also use the laptop to do this. Highlight the pitch points of SFI in your video. Replay the video to yourself to see what others will see and make some corrections if need be.
Then upload your video to YouTube
