Before you get the wrong impression let me say a few things.

Testimonials are for people who earned them. Fake testimonials are always a bad idea! People are smarter then you think. People have a very good lie detector. Earn it by doing people right! Do good at whatever it is that you do. After a person that you did something for likes what you did ask for a testimonial from them!

I just want to give you some tips of how to form what to say in the video:

Set up the story.

…I had problems with {fill in}. The more detailed the better.

Then set up how they found you.

…How others can find you.

Then set up the solution, you.

…Whatever you did to help them is the solution. However you solved there problem is the solution. Not just facts but make it personal! Make it relatable.

“He really gave me my life back!” type of thing.

Make it 100% real and NOT fake! People know fake! Make everything real and true! You will lose everything if people found out that you faked a testimonials! Let your person who is doing the testimonial have fun with it!

How to get video testimonials:
