Use an editing app to trim unnecessary stuff out
Perhaps the beginning of your video features the speaker preparing or hesitating. Maybe they stumbled over a few words or the audio quality was off. To showcase a professional looking video to your market, you’ll need to edit those parts out.
Consider using subtitles or on-screen text
Although we’d like to think that the bulk of video watching goes on during leisure hours, the reality is most people watch videos at work. If the message of your video is not easily communicated through the action alone, you might consider adding subtitles.

Aim to catch attention quickly
