Promo videos are also shot in story format, but do not require pre-production. These are great when you need to promote a brand through an event or want to redirect customers with a quick message. These are also great to promote holidays or special occasions for your target audience. The difference between this one and event videos are the call-to-action and additional graphics needed to get the message across. Background music is also required for this type of video. The average video length is 1 minute, but it may vary depending on the inquiry.
