How to make an explainer video
In this order: decide what the viewer should believe at the end, cut that into scenes with one idea each, build the pictures, review still frames before you pay for motion, and write the words last. The order is the method — most bad videos were simply made backwards.

Why the order matters more than the tools
Across sixty-odd produced videos, nearly every rejected one shared the same root cause: it was made backwards. Script first, pictures bolted on. That reverse order is where narrated slideshows come from — the voice explains while the screen merely illustrates.
The forward order forces each stage to answer to the one before it: scenes serve the claim, visuals serve the scenes, words serve the picture. Nothing floats.
The still-frame review — the habit worth stealing
Split production hard into two phases. Phase one builds only the static set piece and renders still frames: the money shot, the final settled frame, one still per camera framing. Then stop. Nothing moves until someone approves the frames.
The economics are blunt: a bad frame costs minutes to catch as a still and hours to catch as a finished render. One production batch skipped this gate and nine of ten videos were rejected; the next batch, with the gate, passed five of five on first review.
Two field rules: review every camera framing, not just the hero frames — and never accept “looks good on my end” in place of an actual image.
Write the narration last
Narration comes dead last for three reasons. Sync only works one direction — words written to a finished picture can land the key word on the key moment. Division of labor — the voice says what the picture can't show, so if the words lead, the picture ends up subtitled. And cheap edits stay cheap — a wording fix never touches the expensive picture.
Pacing math you can use today: narration reads at about 1.9 words per second. A 9-second scene holds one short sentence; a 12-second scene holds two. Complete sentences, no drama.
Budget for the revision half
From production records, not estimates: simple videos took 4–6 revisions; flagships took 13, 16, and 24, across three staged versions each. Counting rejected parallel attempts, roughly half of all production work was response to review.
Plan the calendar that way. The first pass is about half the real effort — and two habits make the second half cheap: never overwrite a version, and treat a failed video as a restage, not a patch.
Questions
Can I write the script first if writing is how I think?
Write the beats and what each scene must convey first — that's thinking, and it belongs early. The narration prose waits until the visuals are locked, because the exact words carry the timing.
How long should the video be?
60–90 seconds for a single concept. Finished cores in the corpus run about 54–124 seconds; the tight ones are 6–8 scenes with no dead holds.
Do I need to be an animator to use this method?
No. Every gate in it — the one-idea sentence, the scene contract, the still review — is a planning and judgment step, not an animation skill.
Skip the brief. Judge the work.
