The cost of a decent video can vary greatly depending on the type of video, length, and production quality. A basic explainer video with animation can cost anywhere from $1,000 to $5,000. A live-action video with professional actors and equipment can cost $10,000 to $50,000 or more. A realistic budget for a decent video would depend on the specific needs and goals of the project, as well as the production company or freelancer you hire. It's always advisable to get quotes from different production companies or freelancers and compare the prices before making a final decision.
