Completion Rate: Completion rate is the number of people who completed your video divided by the number of people who played it. Completion rate and other engagement metrics are a great way to gauge a viewer's reaction to your video. Do you have a low completion rate? Are people all dropping off at a certain point? This might be a sign that your video content is not resonating with your target audience.
Opinions vary greatly among sound engineers on the best method and equipment for recording audio with a DSLR. You've likely seen many videos that use a lavalier microphone — the small piece that clips below the collar of the talent's shirt. Lavaliers come in both wired and wireless options. However, lavaliers can be a bit obtrusive both for the talent (who has to have a wire threaded down his or her shirt) and for the viewer (who has to see a microphone for the whole video).
Posting your video on social platforms is also basically required, though the social channels you choose may differ depending on where your audience is most active. You’ll also want to think about posting your video natively; most social platforms give native videos preference over video links from other sources. Post your video natively where you can, and keep an eye on your platform-specific data.
Video Marketing is a good way to promote your business. However, it’s not that an easy task and sometimes you need a help from your co-workers like graphic designers if you don’t know how to create or draw your own icon or image to be used in the video. Though you can get from free stock photos and icons sites to compile it for your video, I think it’s better if you create your own.
