How to make a customer testimonial video

A good testimonial is decided before anyone presses record: by the questions you ask and the sound you capture. The edit is where it comes together. This guide covers both, with any editing tool.

What a testimonial video has to do

A customer testimonial video is one or more real customers explaining, in their own words, what changed after they started working with you. The viewer is usually someone a step away from buying, and what they are looking for is a person like them with a problem like theirs.

That means the film is not about your product's features. It is about the customer's situation before, the moment things turned, and what their work looks like now. Your product appears inside that story, not in front of it.

Everything below follows from that: the questions draw out a story, the shoot captures it cleanly, and the edit keeps only the lines that carry it.

Testimonial video questions that produce usable answers

Most weak testimonials come from weak questions. “What do you think of us?” gets a polite, general answer that nobody believes. Ask about events and specifics instead, and let the opinion come out of the story.

  1. Tell me about your work and what your team is responsible for.
  2. Before you started with us, what was the hardest part of that work?
  3. What did you try before? Why didn't it stick?
  4. What made you decide to try something different?
  5. What was the first moment you noticed it was working?
  6. What does a normal week look like now, compared with before?
  7. Is there a number you keep track of that changed? Hours, errors, response time, anything.
  8. What would you tell someone in your position who is still deciding?

Ask the customer to answer in full sentences that include the question. “What was hard before?” answered with “Scheduling” is useless in an edit, because the viewer never hears your question. “Before, scheduling took most of my Monday” stands on its own.

Leave silences. When the customer finishes an answer, wait a beat before the next question. People often add the best, most specific line in that pause. If an answer is vague, ask “Can you give me an example?” and let them tell it again.

Shooting basics: sound first, then picture

Viewers forgive soft focus far more readily than bad sound. Put a lavalier or a close microphone on the customer, record a few seconds of the room before you start, and switch off whatever hums: air conditioning, a fridge, a projector fan. Listen on headphones while you record.

  • Choose a quiet room with something real behind the customer: their workplace, not a blank wall or your logo.
  • Seat them at a slight angle to the camera, looking at you, not into the lens. Frame from mid-chest up, eyes about a third from the top.
  • Light the face from a window or one soft light to the side. Avoid a bright window behind them.
  • If you can, add a second camera for a tighter shot. Cutting between a medium and a close-up hides the edits you make inside an answer.
  • Shoot B-roll: the customer at work, the product in use, the place, the team. Plan at least as much B-roll time as interview time.

B-roll is what lets you shorten an answer without a visible jump. Every time you remove a sentence from the middle of a quote, you need something to show over the seam. Close-ups of hands, screens and objects work well because they fit anywhere.

Structure: problem, turning point, result

Almost every testimonial that works has the same three-part shape. Write it down before you edit, as three short headings, and fill each one with the customer's own lines.

  1. Problem. Who they are and what was getting in the way. Concrete and a little uncomfortable: the viewer should recognise themselves.
  2. Turning point. Why they tried something new, and the first moment it worked. This is where your product enters, briefly.
  3. Result. What their work looks like now, ideally with one specific detail or number. End on a line they would say to a peer.

Open on the strongest line of the problem, not on a name card or a logo. Introduce the person with a lower third over that first answer. Close on their face, not on a product shot. The customer story use case walks through the same shape from one interview and its B-roll.

How to edit a testimonial video: picking soundbites

Start by getting a transcript of the whole interview. Read it once without stopping, and mark every line that is specific, sounds natural and makes sense without the question. Expect most of the interview to go unused. That is normal.

  • Prefer specifics over praise: “We close the month in two days now” over “It's been really great.”
  • Keep a line whole. Cut between sentences, at a breath, never inside a sentence to make it say something it didn't.
  • Listen as well as read. A line that looks perfect on paper can sound rehearsed; a rougher one can carry more feeling.
  • Drop anything that sounds like a sales pitch. The viewer hears it instantly.

Lay the chosen lines in order under your three headings, cut the gaps between them, and watch it. Then cover each join with B-roll, or switch camera angles there. Let the sound carry across the cut: start the next line slightly before its picture, or let a line finish over the next shot. Those small overlaps make an assembled answer feel like one thought.

Cutting several customers into one film

A compilation testimonial is stronger than three separate ones when the customers agree on the same point from different angles. It also means more footage to sort. Work from the structure, not from the interviews.

  1. Transcribe every interview first, so you can search across all of them for a topic: “support”, “switching”, “time”.
  2. Under each of your three headings, collect the best line from each customer that speaks to it.
  3. Pick one customer to open and close the film. A familiar face at both ends holds the compilation together.
  4. Alternate speakers on related points, so the second voice confirms the first.
  5. Give each person a lower third the first time they appear, and only then.

Interviews filmed months apart in different rooms will not match in colour or loudness. Level the voices so nobody is suddenly louder, and use music to tie the parts together. The testimonial video use case describes this situation in more detail.

Length, captions and lower thirds

Length depends on where the film will be watched. A website or sales-deck testimonial can run from one to three minutes; a social clip should make its point in well under a minute. Make the long version first, then cut short versions from it, each built around one line.

Add captions. Many people watch with the sound off, and captions help viewers following a speaker with an accent or in a second language. Check every caption word against the audio, especially names, product names and numbers.

A lower third gives the viewer the person's name, role and company, which is what makes the testimonial credible. Keep it short, keep it on screen long enough to read twice, and make sure it doesn't collide with the captions. For a vertical version, reframe so the face stays centred and the text stays inside the safe area.

Customer testimonial video checklist

  • Written consent from the customer, and their employer if needed, covering where the video will be used.
  • Questions about events and specifics, with full-sentence answers.
  • Clean sound from a close microphone, checked on headphones.
  • A second angle if possible, and plenty of B-roll of the customer at work and the product in use.
  • A three-part structure: problem, turning point, result.
  • Whole sentences only. No spliced quotes.
  • Captions checked word for word, a lower third for each person.
  • A long version, then short versions for each channel.
  • The customer has seen and approved the final cut.

Doing this in Endroll

Endroll is an AI video editor for Windows 10/11 and Macs with Apple silicon. Point it at the folder with your interviews and B-roll, and it prepares everything on your machine: it transcribes the speech, finds the faces and describes what is in each frame. Then you can search every interview at once by what was said, and the results are shots, not files. Star the lines you want and they collect into a paper edit, a screenplay you can put in order and draft from.

Endroll's AI drafts the cut from that screenplay or from a short brief, and lays B-roll where it helps. It does not write words for your customers: every dialogue line is locked to the exact words of a real take, and a point with no matching footage is dropped rather than invented. The screenplay reading shows a coverage heat on each beat, so you can see which points your footage supports before you draft. If you shot two cameras or a separate recorder, Endroll lines them up by their sound and cuts between the angles.

Captions come from the transcript and lower thirds from templates, and captions move above a lower third so the two never overlap. Hand editing never spends credits; AI work shows its price before it runs. When you are done, render the MP4, or open the cut in Premiere Pro, DaVinci Resolve or Final Cut. Your full footage never leaves your machine; the AI works from transcripts, clip descriptions and small preview stills. See Media and search and Titles, captions and graphics in the manual.
