Vertical shorts
Ready-to-post 1080x1920 clips for TikTok, YouTube Shorts and Reels, cut from the same analysis as your highlight reel.
What you get
A short is a vertical clip built from one strong moment, with captions burned in and an optional title card. Each one comes with its own generated title, description and tags, plus a thumbnail.
Shorts are picked from the full pool of good moments ViddyFlow found, not from whatever happened to fit inside your highlight reel. A two minute reel and a twenty minute reel draw their shorts from the same pool, so a short reel never means worse shorts. You can also skip the reel entirely and run a shorts-only job, described in Creating a job.
How many you can ask for
Between 0 and 10 per job, at 10 credits each. Your plan sets the ceiling.
| Plan | Max per job | Notes |
|---|---|---|
Free | 3 | Before your first purchase, including while the trial is active. |
Starter ($5) | 5 | Pay-as-you-go credit pack. |
Pro ($20) | 10 | The full per-job maximum. |
Studio ($50) | 10 | The full per-job maximum. |
Over your cap is reduced, not refused. Asking for 10 shorts on a free account gives you 3 rather than an error, and you are billed for the 3 you actually receive. If you expected more than you got, this is usually why.
Framing
A landscape stream has to become a vertical video somehow. Four ways to do it:
| Mode | What it does |
|---|---|
crop | Fills the vertical frame edge to edge and loses the left and right sides of the original. The default, and the right answer for most gameplay where the action sits near the centre. |
fit | Keeps the entire landscape frame and pads above and below with black. Nothing is cut off, but the video occupies less of the screen. |
split | Your facecam on top, the gameplay underneath, both filling the vertical frame. The classic reaction-clip layout. |
pip | Gameplay fills the whole frame, with up to 4 small floating boxes on top for a minimap, health bar, buff tracker or anything else worth keeping visible. |
Facecam split, in detail
The vertical frame is divided between a facecam panel and a gameplay panel. You control how the space is shared, anywhere from 0.15 to 0.85, with 0.5 meaning an even stack. Push it down to give the game more room; push it up when your reaction is the point.
You can draw an outline around the facecam panel in white, black or violet, which helps separate the two halves when the facecam background and the game are similar colours.
The facecam and gameplay regions default to the usual bottom-right facecam position, so split mode produces a sensible result without you setting anything. If your layout is different, the dashboard lets you drag the regions on an actual screenshot of your own stream, which is far easier than guessing coordinates.
Picture-in-picture, in detail
Gameplay fills the background and up to 4 small boxes float on top. Each box is two separate choices: which part of the original stream it crops from, and where it sits in the vertical output. That is what lets you lift a minimap out of a corner and place it somewhere it will actually be seen on a phone.
PiP has no default layout. Every overlay box has to be placed by hand, because there is no position that is right for all streams. That makes it a dashboard feature: over the API, a PiP job with no boxes renders as a plain crop. Split, crop and fit all work fine over the API. See the API reference.
Captions
Captions are burned into every short by default, as white text with a black outline so they stay readable over bright and dark footage alike. Most short-form viewers watch muted, so this is on for a reason.
You always get an editable caption file. A plain .srt file is produced for every short whether or not captions were burned in. Automatic captioning is never perfect, and a sidecar means fixing one wrong word does not mean re-rendering the whole job: correct the .srt and upload it alongside the video wherever you publish.
Turning burned-in captions off is worth considering when there is little to caption, when the stream is in a language captions come out weaker for, or when you plan to add your own styled captions in an editor.
Title cards
Off by default. When enabled, each short opens with its generated clip title flashed over the video. It gives a viewer a reason to keep watching in the first second, which is exactly where short-form retention is won or lost.
This is separate from the highlight reel's own title card setting, so you can have one without the other.
Adding music
Shorts can have a backing track mixed underneath at low volume, and can rotate between several tracks so a batch does not all sound identical. That is covered in Music and branding.
