How to make a texting-story video for YouTube Shorts
Make a chat-bubble story for YouTube Shorts: write it in the editor, export a vertical MP4 on the Creator plan, and give the Short a title that works on a small screen.
Try it: start from this sample
Flights are booked. Do not panic.
Why would I panic?
I booked them for the wrong month.
Which month did you pick?
Set up for a channel, not just a clip
A Short lives on your channel next to your other videos, so decide what the series is before you open the editor. One recurring pair of characters, one look and one colour scheme make each upload recognisable. The sample uses the WhatsApp-style look, which is on the Free plan; ChatsRat draws its own interface in a similar general style and uses the name only to describe the kind of layout.
Let the typing indicator carry the suspense
This look supports a typing indicator, and the last sample line is built for it: three dots before "Which month did you pick?" gives the viewer one second to guess. Each indicator costs about a second, so use it once or twice in a story, on the bubble that matters, never on every line.
Export and upload
Choose the 9:16 shape and export an MP4; video and the vertical shape are Creator plan features, and the Creator plan limit is 60 seconds. Shorts can run longer, but a chat story rarely needs it. Upload, then write a title that states the situation, such as "He booked the wrong month". Check on your phone that the title does not cover a bubble.
Dates and rules
Shorts can run up to 3 minutes as of November 2026, and the app can be vertical or square, but platforms change these limits, so check the platform's own help page before you publish. Label the story as fiction in the description.
Tips
- Create one reusable template per series so each Short looks consistent.
- Open on the mistake, not on a greeting.
- Watch the first two seconds on mute and ask if you would stay.
- Keep the typing indicator for the single most important bubble.
- Write the title after the script, from the funniest line.
Questions
Do I need the Creator plan for a Short?
You need it for video. The Free plan exports a PNG image with a visible ChatsRat watermark, and video, the 9:16 shape and animation controls are on Creator. You can write the whole script before you pay.
Does a Short need a special hashtag?
No special hashtag is needed to make a video a Short. Shape and length are what matter, so skip any tag that only claims to do this.
Can I make a square Short?
Shorts can be vertical or square. ChatsRat offers 1:1 as well as 9:16 on the Creator plan, though most chat stories read best vertical.
Is ChatsRat connected to YouTube?
No. ChatsRat creates the video file and you upload it yourself. It is not affiliated with YouTube or any messaging app.
Use it for simulated, labelled content. ChatsRat makes mock-ups and fictional conversations for creators, designers and teachers. Do not use it to pass off a made-up conversation as a real one, to impersonate a real person, or as proof of anything. See the Acceptable Use policy.
About the watermark. Exports on the Free plan carry a visible ChatsRat watermark, and every export carries an invisible mark that the verify page can read. Plans list what changes on paid plans.
ChatsRat is not affiliated with, endorsed by or sponsored by any messaging app. App names on this page describe a style only.
