I hired Mark to make a video recording of an evening panel discussion. He was very prompt in responding to questions about the technical details, and working out how best to work the event.
As it turned out, one of the panelists couldn't have video made without prior permission, and it was too late for his office to respond.
Mark was extremely flexible about this, and spent his time setting up and running the audio board for the multiple microphones for the panel and the Q&A instead. Since sound is part of a video, this was just as natural to him as doing the whole video recording. We had no glitches in sound, thanks to Mark, and I'm sure the video would have been equally good if the panelist had given permission.
I really appreciated his punctuality, the clear communication, the flexibility in adapting to our changing circumstances, and his overall friendly and helpful personality. The next time we have a video project, Mark is the first name I'll call.
