Dr. Nick Norwitz
Long-form science content edited for retention without dumbing down the substance. We edit for Harvard-trained PhD / Oxford-trained MD Dr. Nick Norwitz — including many of his most popular videos, with "I Ate 720 Eggs in 1 Month" holding the #1 most-viewed slot on the channel for over a year before being surpassed in 2026.

The work, on the screen
Two of the videos we cut for Nick — both held the channel's top spot at different points in 2025–2026. "720 Eggs" performed at 5.1× the channel median; "Vegetables & LDL" at 3.9×. Watch the actual deliverables below.
The brief
Most science creators on YouTube end up in one of two ditches. Either they water down the science to chase wider reach (and lose the audience that actually watches deep content), or they don't edit aggressively enough for retention (and lose the audience that wanted to keep watching). Dr. Nick Norwitz — Stanford-trained MD/PhD, peer-reviewed researcher in metabolic health — wasn't willing to do the first one and didn't have time to do the second one alone.
The brief: preserve every scientific claim, every citation, every nuance — and still edit for retention. No oversimplification. No fake "you'll never believe what happens next" stings. The audience came for the substance and they had to get it.
What we built
- Editor matched to subject matter. A senior editor already cutting health and science content elsewhere. Familiar with the cadence, citation patterns, and the way scientific arguments unfold over 8–15 minutes.
- Retention through visualization, not compression. Long science videos drop off when viewers can't see what's being described. Our editor builds custom diagrams, on-screen citations, and B-roll graphics that visualize concepts as they're explained — so viewers stay anchored even through dense passages. (See the LDL up/down split in the cholesterol video above.)
- Pacing tuned for an educated audience. Hard cuts on every breath would feel manic. Instead we tuned to leave room for the science to land — but with rigorous removal of "umms," restarts, tangents, and any moment where the viewer's attention would naturally check out.
- Thumbnails that respect the topic. No clickbait shock faces. Our design team built a thumbnail system using clean typography, scientific visuals, and Nick's likeness — packaged to compete in the YouTube grid without betraying the substance inside.
What changed
"720 Eggs" became the #1 most-viewed video on Nick's channel and held that spot for over a year — 581K views and counting. It was eventually surpassed by another video in 2026, but it remains one of the channel's most recognizable pieces and still pulls steady search traffic. The "Vegetables / LDL" video pulled another 268K and outperformed the channel median by 3.9×.
More broadly: this isn't a one-hit case. Mark Studios has edited a meaningful share of the top-performing videos on the channel — the kind of consistent partnership that quietly compounds over a year of uploads, not a single viral moment.
The publishing cadence remained sustainable for a working academic. Nick can keep doing his research and clinical work, and the production engine handles raw shoot to published thumbnail.
