Fact Video Generator. One true fact a day, narrated and labelled.
Describe your channel's niche and Treza writes one fact as a 30 second documentary Short: four generated scenes, a narrator, a music bed, captions, and callout cards that point at what the line describes. Leave the daily trigger on and a new one posts to YouTube every day.
Everything on this page was made on Treza.
One fact, written as a story
A writer model reads your niche and writes one episode around a single subject: a hook in the first line, one surprising and specific detail, and a closing line that sets up the next episode. It also writes the title, the description, and a prompt for each scene.
Four generated scenes
Each scene is drawn as a vertical still first, then Veo 3.1 Lite animates that still into an 8 second clip, so the framing the writer asked for survives the motion. Every shot is generated, nothing comes from a stock library.
Callout cards that point at the subject
The writer picks up to three short labels, a size, a speed, a name, and the thing on screen each one belongs to. The Captions node lands each card as its phrase is spoken, with a fine leader line to that part of the frame.
A narrator over its own music bed
A narrator voice reads the script while a full-song music model scores a bed from a one-line brief the writer wrote for that episode. The bed is ducked 12 dB under the voice and the cut is trimmed to the narration.
Captions for muted autoplay
Whisper times the narration word by word and checks it against the script, then the captions burn in four words at a time in the lower third, clear of the callouts above.
A new fact every day
A schedule trigger runs the template daily, and the writer looks back over its last 30 runs so it does not cover the same fact twice. The YouTube node posts each episode as a Short with the title and description the writer made.
Facts this template made
One subject per episode, four generated scenes, a narrator over a music bed, and a label on the thing being described. These were written and posted by a schedule.
A shark fact
The line on screen as the narrator says it.
Fact of the Day
A callout on the subject
The card points at the part of the frame the fact is about.
Fact of the Day
A creature most people never heard of
The writer mixes famous animals with obscure ones.
Fact of the Day
From idea to finished video
- Step 01
Describe the niche
Open the Fact of the Day template and write the channel's niche in a sentence or two: the subject area, how obscure the facts should be, the tone. Left as it is, the example ocean life niche runs.
- Step 02
Run the first episode
The writer picks the fact and scripts it, the image and video models make the four scenes, and the narration, music, captions, and callouts are laid over the stitched Short.
- Step 03
Check it and tune it
Read the fact before it goes out. Pick another narrator voice, change the caption style, swap the video model on a clip node, or rerun one scene until it looks right.
- Step 04
Put it on a schedule
Connect a YouTube channel and leave the daily trigger on. Set the upload to Unlisted or Private while you are still checking episodes, then Public once you trust the niche.
Every run the account has made, and what each one published.
What people build with it
A daily facts Shorts channel
Ocean animals, space, history, the human body. One fact per Short, posted every day, in whatever niche the brief describes.
Did you know videos without filming
Every scene is generated from the fact it illustrates, so a facts channel needs no camera, no footage, and no clips you do not own.
Animal fact videos
The template's own example niche is ocean life: one creature, named, with the detail that makes it strange. The episodes on this page are runs of it.
History and science explainers in 30 seconds
A mechanism, a number, or a comparison, told as one documentary beat with a label on the thing being explained.
Fact Shorts in another language
The writer is told to write in the language the niche is written in, so a niche written in Spanish gets a Spanish script and Spanish captions.
A facts series for an existing channel
Run it alongside your own uploads as a daily filler format, with the subject area narrowed to what your audience already watches you for.
One fact. Four scenes. Every day.
A new documentary Short from your niche, without a shoot day.
Fact video generator, answered
What is a fact video generator?
A fact video generator turns one fact into a short narrated video with visuals and captions. On Treza, the Fact of the Day template writes the fact from your niche, generates four scenes, adds a narrator, music, captions, and callout labels, and can post a new 30 second Short to YouTube every day.
Are the facts true?
The writer is told to use one real, verifiable fact per episode and to name the subject, and the example niche asks for the same. It is still a language model, so check each fact before it goes public, especially early on. The YouTube node can upload as Unlisted or Private while you review.
Do I need my own footage or photos?
No. Every scene is generated: a vertical still from an image model, animated into a clip by a video model. You write the niche, and the writer picks the fact and describes each scene from it.
What are the callout labels?
Short cards like a size, a speed, or a name that appear while the narrator says the matching phrase, with a thin line pointing at the part of the frame they describe. The writer chooses up to three per episode, and one that cannot be matched to the narration is left out rather than shown in the wrong place.
Will a daily facts channel repeat itself?
The writer node has Avoid recent repeats switched on and looks back over its last 30 runs, so each day it is told which facts it already covered and picks a new one.
Can I change the voice, the model, or the length?
Yes. The narrator is a text to speech node with its own voice setting, and each scene clip is its own node, so you can pick a different video model there. A longer episode means more scene and clip nodes on the canvas, and one Sequence stitches up to 12 shots.
How much does it cost to make a fact video with Treza?
Treza runs on prepaid credits with no subscription. Each generation is charged at the model's own rate from your balance, and a failed generation costs nothing. A typical video generation settles around $1.06, and credit packs start at $5 and never expire.
Can I call this as an API instead of using the canvas?
Yes. Every pipeline can be published as a versioned HTTP endpoint. Call the typed /invoke endpoint with JSON in and JSON out, or point any OpenAI SDK at the OpenAI-compatible endpoint. Swap a model on a node later and the API your product calls does not change.
Do I need to know how to edit video?
No. Start from a template, change the topic, and run it. If you do want frame-level control, the timeline editor is there with multi-track video and audio, per-clip trims, fades, and volume, but nothing about the automated path requires opening it.
