About
Justin Gim Ho Cheung
Creative Director, Grand Blade Media
Bio
I direct Grand Blade Media, a digital marketing studio that is me and a lot of software. I run three YouTube channels. A production system has run behind Carousel Studios & Lab since August 2026. In all I have built 40+ tools and apps in-house. The ones behind the channels make and post the videos.
Tool count: 40+ in-house tools and apps. Source: Justin’s own project index, counted Oct 2, 2026.
Manifesto
Seven rules, each with a receipt.
A rule is worth printing only if the work shows it.
00 · Start here
These are the rules the work runs on. Each has a receipt from a channel I run, so you can check the claim instead of taking my word. If one sounds like how you want your channel run, write to me.

01
Never sell an untested method.
I do not recommend a method I have not run on one of my own channels. If it fails, it should fail on my work first, where the cost is mine. That rules out a lot of fashionable advice, and I am comfortable with that.
Receipt: public auto-publishing on Carousel Studios & Lab began Aug 11, 2026. In its window, Sep 18 – Oct 1, 2026, it published 50 public videos. Source: YouTube Data API read via our own tooling, as of Oct 2, 2026.

Numbers get dates.
A figure with no date is an opinion. Every number I publish carries its window, its as-of date and its source, or it stays off the page. Lifetime totals never lead, because they cover a longer span than any window and cannot be compared with one.
Receipt: the public About page of Carousel Studios & Lab, read Oct 2, 2026, lists 142k lifetime views: every public upload since the channel joined. That total is not split by production system and not comparable with the window, so no page here leads with it.

Pipelines beat heroics.
Posting four times a day by hand is a heroic effort, and heroics do not last. So the machine does the daily volume and I keep the decisions: the format, the voice, the look, the rules.
Receipt: Carousel Studios & Lab averaged 3.6 public videos a day across Sep 18 – Oct 1, 2026, as of Oct 2, 2026. The schedule allows up to four a day. Source: YouTube Data API read via our own tooling.

04
Taste is a spec.
Taste that lives only in my head cannot be repeated or checked. So I write it down as rules a machine can follow and a person can audit, and I measure the result instead of trusting my eye. Caption placement is the cleanest case: burn a frame, then measure where the words landed.
Receipt: Where captions go on a Short: measure it, tested on Carousel Studios & Lab and published Oct 2, 2026.

Ship daily, judge by the median.
Daily output is how a channel learns what it is. But one video is an anecdote, so I read results across a window and put the median beside the best. The best video makes a good screenshot. The median is what the channel actually does.
Receipt: on Carousel Studios & Lab the best video reached 1,492 public views and the median video 676, across 50 videos, Sep 18 – Oct 1, 2026, as of Oct 2, 2026. Of those 50, 4 stayed under one hundred views. Source: YouTube Data API read via our own tooling.

Keep a kill switch.
Volume without a brake is a liability. Anything that publishes on a schedule needs a way for one person to stop it mid-run, and a place to hold what fails its checks.
Receipt: as of Oct 2, 2026, the system behind Carousel Studios & Lab re-reads its kill switch while it runs and puts a Short on QA hold when an automated repair fails.

Say what did not work.
A site that shows only wins is an advertisement. So the misses sit beside the hits, at the same size. The Night Edition, a one-hour film, is the plainest example: it has almost no audience, and I would rather print that than hide it. The Lab keeps the full list.
Receipt: The Night Edition, a one-hour film on Carousel Studios & Lab, public since Sep 26, 2026, had 11 public views and 0 likes as of Oct 2, 2026. Source: YouTube Data API read via our own tooling.
These are channels and systems we own and run. They are not client results and are not a forecast of yours.
How this is made
What the machines do, and what a person decides.
We use AI and automation to make content, and we would rather you read how than guess.
Done by systems
- Public trend feeds and web research pick the day’s story for Carousel Studios & Lab.
- A script is written from researched, dated facts and passes an automated check before it is narrated.
- Carousel Shorts are presented by an AI version of me, and the narration is my cloned voice. Each Short’s YouTube description says so.
- The pictures are mostly photos credited on screen, except when the AI version of me is speaking, and an automated visual check judges each still.
- The Short is assembled vertically, then scheduled to publish up to four times a day.
- The Night Edition is an AI-made music track looped over twelve generated scenes, each a still turned into a short animated loop.
- Video production runs on one desktop machine with a single 16 GB graphics card. The research and script step uses a hosted AI model, so not everything runs on that machine.
Decided by a person
A person chooses the format, the voice, the look, the rules and the safety rails, decides what the system may publish and what it may not, and holds the kill switch for the days the checks miss something.
Whether the volume is any good stays a human question.
Safety rails
A QA hold stops a Short from publishing when an automated repair fails. A kill switch is re-read while the pipeline runs, so it can be stopped mid-run. None of this runs without a person responsible for it.
Labels
- On Shorts the production system uploads, YouTube’s altered-content label is set at upload.
- We do not present AI-assisted work as human-made.
Known gaps
The research step is told only what ran in the last two days, so the same story has run under reworded titles, up to three times in two weeks on Carousel Studios & Lab. As of Oct 2, 2026, widening that look-back is on the to-do list. It is not done.

Ways to work together
There are three: a teardown, a build and a run. What each one includes, what it costs, what we need from you and who each suits are on the Services page.
Start with a channel teardown.
Send the link to one channel and tell me what you want to change. You get a written audit and plan with specific fixes.
