Videos are a popular marketing tool, but if the length of the video is inappropriate, the marketing campaign could fail. To avoid this, the video must be long enough to create impact and get the point across but short enough to not lose the attention of the viewer.
A video about a company or a consumer testimonial is best if kept under a minute, while product-related videos are acceptable if stretched to 3 minutes.
Certain videos do not fall under any time restrictions provided they showcase creativity and provide entertainment.
