Mastering Client Testimonial Videos: Behind the Scenes at the Charles Schwab Impact Convention


California-based Slice Editorial hired SVG to record client testimonial video interviews at the Charles Schwab Impact Convention.

Taking place at the Massachusetts Convention and Exhibition Center, we were able to set up in a large room with our equipment and, most excitingly, our green screen!

Setting Up for Success

Arriving on Tuesday night to create and tweak the setup, our DP and audio recordist assessed the environment and decided how to create the shot.

We first set up the portable green screen, a large anti-wrinkle piece of rectangular fabric clamped firmly to a couple of stands.

Wrinkles are the enemy when using a green screen, so making sure the surface was completely flat was extremely important.

We were also able to export a test recording on site and experiment with how it would look once the background image was placed.

This allowed us to make any necessary adjustments to ensure a flawless final product.

Perfect Lighting

Next, lights were built around the setup to ensure that the subjects would not appear flushed or flat from the fluorescent overheads.

Chuck used two bi-color LED lights and several floods to create the right composition that would focus and flatter the subjects.

It’s important that interviews are well-lit; otherwise, harsh shadows may convey a noir-type interrogation mood that doesn’t quite fit the intention. Proper lighting also helps highlight facial expressions and body language, which are crucial for engaging and authentic testimonials.

It was also important to light the set correctly because many of our subjects had blonde hair, so a green reflection from the screen behind them was a potential problem.

By carefully balancing the lights, we could minimize any unwanted reflections and ensure a clean, professional look.

Tackling Sound Challenges


Our recordist was concerned about sound pollution because the room was located right off the main hallway, and we could easily hear people talking and laughing from outside.

To combat this, we set up some sound blankets in a triangular shape around the subject and the lights to insulate the acoustics as much as possible.

He also used audio filters to cover a loud hum in the room. This is a typical concern when shooting an event video, but there are always ways to ameliorate the issue before hitting record.

Additionally, we positioned our microphones strategically to capture clear, crisp audio while minimizing background noise.

Engaging the Interviewees

To ensure that the subject’s attention was focused on the camera, our interviewer utilized an eyeliner.

This device is mounted to the tripod directly in front of the camera and allows the lens to pass through and capture the image without distortion while also (from the perspective of the subject) projecting the face of the interviewer over the lens using mirrors inside the structure.


Although it seems like an odd concept, this makes the subject feel as though they are having a conversation with the interviewer rather than performing in front of a camera.

This technique helps reduce anxiety for those unaccustomed to being on camera and ensures that the speaker talks to the camera, creating a more direct and informative shot for the DP and, ultimately, the audience.

For any business-oriented video, it is always necessary for the subjects to be able to exude confidence and passion in what they’re speaking about in order to really connect with the audience.

Final Preparations and Execution

Sasha, our interviewer, flew into Boston on Tuesday night to help set up and practice using the eyeliner with our team.


Our DP also set up his Sony FS3 prior to the early morning call, so we would be ready to roll as soon as the talent arrived.

Small adjustments were also attended to, such as using scraps of black cloth for masking the shot, something we always make sure to keep handy on set for those last-minute perfections.

Attention to these details ensured that our setup was both efficient and effective, allowing us to maximize our shooting time.

A Day of Interviews


The steady stream of interviews on Wednesday kept us all busy, but we had fun interacting with each of our subjects and perfecting sound bites for the final cut.

Incorporating many different talking heads to offer their unique points of view on a single topic is a very effective video marketing strategy because it allows the audience to see a diverse presentation of opinions.

This approach not only enriches the content but also helps build credibility and trust with the audience.

The footage we collected covered a large array of topics and is sure to make for a truly effective compilation.

Reflections and Future Plans

Looking back, the meticulous planning and execution paid off.

Each interview added a unique perspective, and the high-quality visuals and audio ensured that every testimonial would resonate with viewers.

This project reinforced the importance of thorough preparation and adaptability in video production.

We look forward to more opportunities to showcase our expertise and create impactful videos for our clients.
