First, decide what you want to say. Then draft this out as a one minute script. You'll have lots of existing copy to help you, such as brochures, reviews or promotional materials. Keep your message inside 100 words, which is approximately 1 minute of video runtime. Now, using our prepared template, decide on a suitable image for each key phrase or sentence in your script. Every sentence needs a picture. Typically you'll need 8 to 12 images. It's easy.
