Long-form YouTube edits built around the retention graph: a hook that promises the payoff early, pacing that carries viewers past the midpoint, graphics and b-roll where the talking slows, and Shorts cut from the same upload.
Mark Studios is a YouTube video editing agency for creators and brands who upload on a schedule. Mark Santos, who has run his own channel since 2011, edits every video in-house: you send the raw footage and the topic, and get back a finished 16:9 upload with captions, graphics and music, plus Shorts cut from it if you want them. Standard turnaround is 5–7 business days. Start with one video in the instant quote, or put a weekly upload on a monthly plan.

Vertical Shorts cut from the long video and captioned for 9:16Market context on YouTube copyright: Content ID made about 2.5 billion claims in 2025, and uploaders won about 67% of the disputes they filed. Details in our YouTube copyright statistics. Personal finance creators who publish their own figures report a median RPM of $10.96 per 1,000 views; every niche is in our YouTube CPM and RPM by niche. Big channels schedule: 51% of their latest uploads went live at exactly :00 or :30, in our YouTube upload time study.

Upload the A-roll, b-roll and any screen recordings to a shared folder, retakes included, then add the title idea, the thumbnail concept if you have one, and a past upload that did well. A script or bullet outline helps; a topic and a rough order is enough for an unscripted video.
A single video is priced in the instant quote from its raw footage and extras such as thumbnails; a weekly channel goes on a monthly plan. Either way the price is fixed before you pay, and nothing is billed by the hour. For what other routes charge, see what a YouTube video editor costs in 2026.
The first cut is the whole video, not a rough assembly: the hook rebuilt so the payoff is promised early, retakes and tangents gone, b-roll and text over the slow stretches, music and a sound mix. You can judge it the way a viewer would.
YouTube notes are mostly about the opening and the pace: start on the reveal, this section drags, use the other take, the graphic covers my face. Pin each note to its timestamp in the review tool; 3 rounds are included and each comes back in 24–72 hours.
Delivery is a 16:9 MP4 encoded for YouTube, any Shorts as 9:16 files, the thumbnail and a chapter list for the description. Standard turnaround is 5–7 business days with rush available.
Mark started editing for his own channel in 2011 and grew it past 200K subscribers. He cuts with the retention graph in mind: where viewers leave in the first 30 seconds, where a middle section sags, and whether the video keeps the promise its title and thumbnail made.
Mark Studios edits Dr. Nick Norwitz's long-form science videos, including “720 Eggs”, which held his channel's top spot for over a year and is now at 637K views, with every citation kept on screen. The Nick Norwitz case study shows how that edit is built.
Every plan includes thumbnails, and Growth adds titles and SEO, so the packaging comes from the person who knows the video best. Shorts are cut from the same footage, which keeps the channel's look the same on the home feed and the Shorts shelf. On the 99 most-subscribed YouTube channels, 44% of the latest uploads are Shorts, according to our YouTube video length study.
“He's a good communicator, he's amazing to collaborate with, and most importantly, he's driven. He helped me build my YouTube channel and put out good quality content.”
On a monthly plan, from $750 a month: Starter covers one long-form YouTube edit (up to 15 minutes of footage), 4 Shorts and 2 thumbnails. Growth, at $2,000 a month, is 4 YouTube videos with thumbnails, titles and SEO plus 8 Shorts, which works out to $500 per weekly video. Scale is $2,700 and Unlimited is $3,500 (markstudios.com/pricing). A single video gets a fixed price from the instant quote before you pay.
Raw footage length matters most, then the work per minute: motion graphics, sourced b-roll, sound design, and how many Shorts you want from the video. A 10-minute sit-down talk with simple text is a different job from a 10-minute video with an animated graphic on every point. The instant quote prices those inputs into a fixed price before you pay; what a YouTube video editor costs in 2026 compares freelancers, agencies and plans.
Standard turnaround is 5–7 business days from complete footage and brief, and rush delivery can be added at checkout. On the Unlimited plan, the first draft of each request arrives within 3 business days. If you publish weekly, filming about a week ahead gives each video time to clear its revision rounds before its release slot.
Mark Santos. You work with him directly on every upload instead of being handed between freelancers, and your channel's fonts, colors and recurring graphics go into a written style sheet so each video matches the last. Every video includes 3 revision rounds of timestamped notes, each back within 24–72 hours.
Yes. Send links to two or three uploads you consider on-brand, and the edit copies what defines them: cuts per minute, caption font and placement, color, music energy and how graphics enter the frame. After the first month those choices are written down, so a new upload never needs the style re-explained.
Both. Scripted videos are cut to follow the script, using the best take of each line. Unscripted footage, like a sit-down talk or a long walk-and-talk, is restructured: the strongest point moves toward the front, repeats come out, and the order is rebuilt so the video makes one clear argument.
Yes. Every monthly plan includes Shorts (4 on Starter, 8 on Growth, 24 on Scale), and they can come from the long video, so one shoot fills both. Each is reframed to 9:16, captioned and trimmed around a single moment. For Shorts as a service of their own, see short-form video editing.
Music comes from royalty-free libraries licensed for monetized YouTube videos. If you have your own library subscription or a track you've licensed, send it and the edit uses that instead. Commercial songs you don't hold a license for are left out, because they're the usual source of Content ID claims and muted audio.
Yes, as a separate service. Editing plans don't include posting, but video posting puts each finished video live with its title, description, tags, thumbnail and end screen, at the time your audience usually watches. On the Growth plan, the title and SEO for each video are already written.

YouTube was the platform named most, in 42% of the 698 first messages in our what buyers ask before hiring a video editor study, and long-form edits ordered on their own were due a median 6 days after ordering across 2023 to 2026 (video editing outsourcing benchmarks).
Not a fit if you want guaranteed views or subscribers. Nobody controls the algorithm, and Mark doesn’t promise numbers.
