# Vertical AI clips for TikTok and Reels, set up in one sentence

> Say vertical, TikTok or Reels and Ask sets 9:16. Clip lengths per plan, three engines for short clips, takes, and a weekly batch routine with its credit math.

Published 2026-09-29 · eroq.ai — canonical: https://eroq.ai/blog/vertical-ai-clips-for-tiktok-in-one-sentence


A vertical clip is four decisions — format, length, engine, subject — and Ask takes all four in one sentence. Type "vertical, 5 seconds, a barista slides a latte toward the camera" into the bar at the top of [the studio](/studio) home, and the Video tool opens set to 9:16 and five seconds, with the prompt written. Nothing renders until you press Generate.

This guide is the short-form side of [Ask](/ask), from the words that mean 9:16 to a weekly routine and its credit math.

## The words that mean 9:16

Any of these sets the clip to 9:16: **vertical, portrait, TikTok, Reels, Stories, Shorts.**

```text

```

The grey line under Ask's reply says what it set; about a second later [the Video tool](/studio/video) opens with it filled in. Ask only sets what you asked for — here the format and the camera move. Everything else stays as the Video tool has it, the engine included: the last one you used, or Seedance 2.0 Mini on a new account.

Other placements: landscape, horizontal or YouTube is 16:9; square is 1:1; cinema or ultra-wide is 21:9 (video only). Images take 1:1, 3:4, 4:3, 9:16 and 16:9.

## Length, and what each plan allows

Say the seconds — "5 s", "a 10-second clip" — and the page snaps to what the engine renders and what your plan allows. Longer clips unlock with a plan: up to 15 s on Hobby, 20 s on Creator and 30 s on Studio. [Pricing](/pricing) has the rest.

```

On Seedance 2.0 Mini, five seconds is 45 credits and ten is 90: test a hook at five, and give ten to the clips that earned it.

## Three engines for short vertical clips

Prices are credits per clip at the engine's default settings:

| Engine | 5 s | 10 s | Plan |
| --- | --- | --- | --- |
| [Seedance 2.0 Mini](/models/seedance-2-0-mini) | 45 | 90 | any plan |
| [Wan 3.0](/models/wan-3) | 135 | 270 | any plan |
| [Kling 3.0](/models/kling-3) | 170 | 340 | Hobby |

- **Seedance 2.0 Mini** is the cheapest line in the table and the engine a new account starts on — the one to hold a daily cadence on. Say "Seedance" and Ask sets it.
- **Wan 3.0** also runs on any plan and goes long — up to 30 seconds, where your plan allows it. Say "Wan".
- **Veo 3.1 Lite**, the third engine on every plan, renders 4, 6 or 8 seconds rather than 5 or 10 — 112 credits for eight. Say its full name: "Veo" alone means Veo 3.1, which needs Creator.
- **Kling 3.0** is what "with Kling" means: a family name sets its standard engine, not the Pro. It unlocks with Hobby; on a plan without it, Ask proposes instead of jumping — an **Open Video →** button and the plan badge — and the page opens with its Unlock button.

```text

```

Not sure? Ask "what's the cheapest video engine?" or "which engine does 1080p with sound?" — Ask answers from the studio's live catalogue and offers to open the right tool. The [engine guide](/blog/which-ai-video-engine-ask-picks) has the rest.

## Takes: one to four

Ask sets one to four takes — say "three takes" or "two versions" — and each take is a clip of its own, so three takes of a five-second Mini clip cost 135 credits.

```

Spend takes on the hook and keep the rest at one; [batching takes](/blog/batching-takes-without-burning-credits) goes further.

## A weekly batch routine, by follow-ups

The thread keeps context, so after the first sentence each clip is a short one. Five clips a day, one thread per day:

1. **Open each day with a full sentence** — format, length, subject, a camera move and the library folder to save into. Name an engine when you want a particular one; otherwise the page stays on the last one you used.
2. **Generate, then come back.** Press the browser's back button, or the **Ask** row in the left rail, to get back to the day's chat. Or press ⌘K (Ctrl+K on Windows) on any studio page, type the next ask and pick the last row, **Ask eroq: "…"**: it goes to the chat in progress.
3. **Follow up with what changes.** "The same, but at night", "rather with Kling", "make it 10 seconds".
4. **Read the grey line every time.** It shows 9:16 and the seconds when they are set, and the engine when you named one. If something is missing, say it again.
5. **Start a new chat for the next day's five.**

```text

→ Setting up Video · 5 s · 9:16 with your parameters…

Rather with Kling
→ Setting up Video · Kling 3.0 · 5 s · 9:16 with your parameters…
```

The folder must already exist in your [library](/studio/library); more follow-ups are in the [conversation guide](/blog/iterate-ai-video-by-conversation).

## The credit math for a week

Five clips a day is 35 a week. One take each, at default settings:

| Routine, 5 clips a day | Credits a week | Four weeks |
| --- | --- | --- |
| Seedance 2.0 Mini, 5 s | 1,575 | 6,300 |
| Seedance 2.0 Mini, 10 s | 3,150 | 12,600 |
| Veo 3.1 Lite, 4 s | 1,960 | 7,840 |
| Four on Mini + one Kling 3.0 hook, 5 s | 2,450 | 9,800 |
| Kling 3.0, 5 s | 5,950 | 23,800 |

Set that against a plan's monthly credits: Hobby is 1,800 for $15, Creator 6,000 for $49, Studio 20,000 for $149. The base routine — five Mini clips a day at five seconds — runs 1.14 weeks on Hobby's credits, 3.81 on Creator's and 12.7 on Studio's. Two takes of everything doubles every line. When a week runs past the plan, a Starter pack adds 1,000 credits for $10.

## What Ask will not do

- **Render by itself.** Generate stays your click, with the usual credit check. Asking is free.
- **Caption, add music, post or schedule.** Ask sets up the clip and stops there: captions, music, posting and scheduling happen in the apps you already post with.
- **Upscale or lip-sync.** eroq has neither, and Ask says so instead of pretending.
- **See inside your clips.** "Open the latte clip" finds renders by the words of their prompt or title, not by what is in the picture ([finding renders by description](/blog/find-old-ai-renders-by-description)).

The wider vertical workflow is on the [social shorts use case](/use-cases/social-shorts).

## FAQ

### How do I make a 9:16 AI video for TikTok?

Type what you want into Ask with "vertical", "TikTok", "Reels", "Stories" or "Shorts" in the sentence. The grey line confirms 9:16 and the Video tool opens set to it, with the prompt written. Press Generate when it looks right.

### How long can an AI clip for TikTok be on eroq?

Up to 15 seconds on Hobby, 20 on Creator and 30 on Studio. Whatever you ask for, the page snaps to what the engine renders and what your plan allows.

### What is the cheapest engine for daily vertical clips?

Of the engines here, Seedance 2.0 Mini: 45 credits for five seconds, on any plan. Say "Seedance" and Ask sets it; ask "what's the cheapest video engine?" to check the live catalogue.

### How many credits does posting every day take?

One five-second Mini clip a day is 1,350 credits over 30 days; five a day is 6,750. Compare that with Hobby's 1,800 or Creator's 6,000 monthly credits, and double it if you shoot two takes of everything.

### Does eroq add captions or post to TikTok for me?

No. eroq renders the clip; captions, music, posting and scheduling happen in your editor and in the platform's own app.

### Can I say the request instead of typing it?

Yes. Tap the mic in the bar and speak. It uses the browser's own speech recognition — Chrome, Edge and Safari; the mic is hidden in browsers without it, such as Firefox — and when you stop talking, the words send themselves. The [voice commands guide](/blog/voice-commands-for-ai-video) has examples.

[Open the studio](/studio), type "vertical, 5 seconds" and your first shot, and read the grey line before [Video](/studio/video) opens.
