Since video production is completely tailored to your needs, it is almost impossible to give blanket answers to questions like, "How much does a 5 minute video cost?" Video production has four distinct phases. Variables in any of these determine the final cost of a program.
Pre-Production
Production
Post-Production
Distribution
An industry rule of thumb estimates about $1,100 per finished minute of video for a quality presentation, but we find that we usually come in closer to $850 per minute for the typical 5-8 minute corporate video involving a script, voice talent, and illustrating footage. The final budget always depends on what exactly you want to see on the screen during those minutes. A helicopter fly-over of your facility is very impressive, but obviously costs more than a camera person taking the shot from across the street. A custom animation of your logo costs more than us simply importing a JPEG file. You get the idea.
