Recording customer testimonials and case studies for your business: how to do it well

A badly recorded customer testimonial can do more harm than having none. If the video looks dark, the audio sounds like a WhatsApp call and the person seems to be reading a script, the message you send is the opposite of what you wanted. The camera amplifies discomfort just as it amplifies authenticity.

At A0Studios we have recorded testimonials and case study pieces for marketing teams, agencies and companies that need this kind of content to close sales, justify investments or strengthen credibility in tenders. What makes the difference is not budget: it is process.

Why video testimonials are the hardest content to fake

Any brand can write that its customers are satisfied. Video cannot be faked the same way. When a real customer speaks naturally on camera, without sounding like they are reciting, the impact on the viewer is qualitatively different from a written review or a logo in a clients section.

That explains why the B2B sales teams we work with prioritize this format for presentation decks, proposals and follow-ups. A 90-second video of a real customer explaining which problem they solved and why they chose the provider can replace several pages of documentation.

How to record a testimonial that builds trust

Preparing the person before recording

It is not about handing them a script. It is about having a 10-15 minute conversation before turning on the camera, so they arrive knowing what they will be asked and why. Nobody speaks well when surprised. At A0Studios we prepare the interviewee with a list of 4-5 open questions shared in advance, not so they rehearse answers, but so they arrive having thought about it. The difference in body language is immediate.

The space, the camera and the sound

A testimonial recorded in a meeting room with ceiling lights and air conditioning humming in the background will not work, even if what the person says is brilliant. Technical quality shapes credibility. In the A0Studios penthouse we work with Sony A7 cameras in medium or cowboy shots, soft Aputure lighting that does not make the interviewee squint, and a Rode lavalier microphone to isolate the audio from the sounds of central Madrid. The result looks like a short documentary, not a videoconference recording.

The questions that work

The worst questions for a testimonial are the ones answered with yes or no. "Are you satisfied with the service?" produces exactly the kind of flat answer that convinces nobody. The questions that work are open: "What was the situation before you started?", "What surprised you the most?", "Who would you recommend this to?". The pattern is always situation, change, recommendation. Those three answers, well recorded, practically edit themselves.

Common mistakes that ruin a video testimonial

• Handing the interviewee the full script: the result always sounds like read text.
• Recording at the client's office without controlling the space: messy backgrounds, overhead light, ambient noise.
• A fixed shot from too far away: it loses emotional connection. A medium shot works better.
• Not leaving silences: the interviewer's nerves fill with questions the moments where the client was about to say something valuable.
• Editing with too many corporate elements: logos on screen, intrusive music, text over text. A testimonial lives on the face and the voice.
• Not recording cutaway shots: they are always needed so the editor can cut without visible jump cuts.
