Stock footage and an AI voice: what makes a Short yours on YouTube
YouTube lists image slideshows and generic AI templates with minimal narrative as not allowed. What your script and edit must carry with stock clips.
A Short built from stock footage and an AI voice is not banned by anything I read on YouTube's pages. The inauthentic-content section lists image slideshows, templated storylines or scrolling text with minimal or no narrative as not allowed, and AI content from generic templates that looks mass-produced (read 2026-10-03). The footage is not the problem; the absence of a point of view is.
That reading fits the October 1 change, where YouTube is reported to have said that voice-over describing what is on screen, minor technical edits and template-based bulk changes do not make a reused clip original (Search Engine Journal, read 2026-10-03). For stock footage you licensed, 'original' means your script, your structure and your edit.
Where the originality lives in a faceless Short
If the pictures could belong to any channel, the words must belong to yours. A faceless Short has several layers, and the table shows which can be yours when the clips are not.
| Layer | Stock or generated | Can be yours |
|---|---|---|
| Script | No | The claim, the examples, the order, the conclusion |
| Footage | Usually licensed or generated | Selection and sequence, never the clips themselves |
| Voice | Synthetic or recorded | Phrasing and pacing, if you write it |
| Edit | Tool-made | Timing against the argument, the cut to the proof |
| Captions | Tool-made | Emphasis that matches what you want remembered |
Build the script before the footage
This is the opposite of the pattern YouTube's page describes as mass production: the same template with swapped nouns.
- Write one sentence a viewer could disagree with. That is the Short.
- Add two pieces of evidence you chose: a number you looked up, a test you ran, a quote you checked.
- Only then pick footage that matches each sentence. If a sentence has no picture, shorten the sentence, not the picture.
- Read the script aloud once. If it could be about any product or topic, rewrite it.
- End on what the viewer should do or decide, not on a recap.
What Sume does and does not supply
I found no stock footage library in Sume's docs, so licensing the clips is your job. Timeline 1.0 accepts your own hosted clips against one audio spine. Video captions burns captions onto a finished clip; with cues you pass exact text and times, which also works when the clip has no speech.
If you generate B-roll instead, disclosure becomes the question. YouTube's page asks creators to disclose realistic content that was altered or synthetically generated, including realistic scenes that did not occur, and exempts production assistance such as scripts, thumbnails and captions (read 2026-10-03). A photoreal generated scene needs the label; clearly unrealistic content does not.
The honest limit
A good script does not guarantee distribution. Sume does not guarantee reach, and YouTube has published no dashboard or threshold for how it weighs originality (Search Engine Journal, read 2026-10-03). What you can do is make each Short so specific that the footage could not be swapped without changing the meaning. If it can be swapped, the Short is probably the template YouTube's page describes.
A short example
Take a Short titled 'Why your sourdough doesn't rise'. The generic version narrates three tips over kitchen clips. The version that carries your point makes one claim, such as that water temperature matters more than proofing time, and shows a test you ran, with numbers. The footage can still be licensed clips of dough; the value is the claim and the test.
Write the claim first, then check each cut against it. If a clip does not support a sentence, cut the clip.
Using the stock library you already pay for
If your stock footage comes from a licensed provider, read its terms about use in monetized videos and whether the clips can appear in an AI-assisted edit. YouTube's pages are about originality and disclosure, not licensing, so they will not tell you either way.
Keep a record of which clip came from which license, with the date, in the same spirit as a source log. If YouTube or a rights holder asks later, you will have the answer in one place.
When you add an AI voice, the disclosure page exempts production assistance but not realistic synthetic voices of real people. A clearly synthetic narrator is a different case from a cloned voice that sounds like someone specific (read 2026-10-03). Do not clone a real person's voice without their agreement.
A sanity test
Mute the footage and read the script aloud to a friend. If it still holds attention, the footage is support. If it falls apart, the footage was carrying the Short, and the Short is what YouTube's pages call mass-produced.
