How do I make an AI video for Instagram Reels?

Send a text prompt or a photo to the AIVidLab Telegram bot, choose the vertical 9:16 format, then add optional voiceover and captions. The AI generates a Reels-ready clip you can download and post in minutes — no filming or editing app needed.

What aspect ratio should Instagram Reels videos use?

Reels and full-screen feed videos use vertical 9:16 (1080x1920). Generate your AI video directly in 9:16 so it fills the screen without black bars or awkward cropping. For a grid post you can also use square 1:1 or 4:5.

Can I add voiceover and captions to an AI Instagram video?

Yes. You can generate an AI voiceover from a script and add on-screen captions so your Reels stay watchable with the sound off. Captions boost watch time because most people scroll Instagram on mute.

How much does it cost to make AI videos for Instagram?

Videos start from around US$0.15 each. You pay per video with tokens and there is no subscription, so creators and brands can produce a steady stream of Reels affordably.

How to Make AI Videos for Instagram — Reels & Feed

AIVidLab Guide · Updated July 2026 · 6 min read

Want to post more Reels but hate filming and editing? Here's how to make AI videos for Instagram from a simple prompt or photo — vertical 9:16, with voiceover and captions, ready to post. Videos start from around US$0.15.

Instagram now runs on video. Reels get pushed to non-followers, and the algorithm rewards accounts that post consistently. The problem is that shooting, editing and re-shooting eats hours you don't have. AI video flips that: describe the clip you want, pick the vertical format, and get a finished Reel in minutes — no camera, no editing timeline, no on-screen talent needed.

Why use AI video for Instagram Reels?

Post consistently — the algorithm favours accounts that show up daily
No filming — generate scenes from a prompt or a single photo
Native 9:16 vertical — fills the screen, no black bars or crop
Voiceover + captions built in — watchable with the sound off
Cheap to test — from ~US$0.15 per video, no subscription

Tip: The first 1-2 seconds decide everything on Reels. Open on motion or a bold visual, not a slow fade. Generate two or three different hooks for the same idea and post the one that stops the scroll.

How to make an AI video for Instagram — step by step

Start from a prompt or a photo

Open the AIVidLab Telegram bot and either type what you want to see (a scene, product, or vibe) or upload a reference photo. Text-to-video is great for fresh ideas; image-to-video keeps a real product or subject accurate.

Set the format to vertical 9:16

Choose the 9:16 aspect ratio (1080x1920) so the clip is built for Reels and full-screen feed from the start. Generating vertical up front means no awkward cropping later.

Add voiceover and captions

Generate an AI voiceover from your script, then add on-screen captions. Most people scroll Instagram on mute, so captions keep them watching — and higher watch time means more reach.

Generate, download and post

Hit generate, wait a few minutes, and download your Reel. Write a short caption, add a few relevant hashtags, drop in trending audio if it fits, and publish. Repeat for the rest of the week's content.

Formats and aspect ratio for Instagram

Getting the size right is half the battle. Match the format to where the video lives:

Reels & full-screen feed — vertical 9:16 (1080x1920)
Grid / in-feed posts — 4:5 portrait or 1:1 square
Stories — 9:16 again, keep key text away from the top and bottom edges

When in doubt, make it 9:16. It's the format Instagram pushes hardest, and it doubles as ready-to-use content for TikTok and YouTube Shorts.

Adding voiceover and captions the right way

A silent AI clip is fine, but voiceover and captions turn it into content people actually finish. Keep the script tight — one clear idea per Reel. Write for the ear, use short sentences, and front-load the payoff. For captions, use large, high-contrast text and keep it to a few words per line so it reads instantly on a phone. Position captions in the middle third of the frame so the Instagram UI doesn't cover them.

Content ideas for creators and brands

Faceless niche pages — travel, motivation, facts, or aesthetic loops with voiceover
Product teasers — turn a product photo into a moving Reel for a launch
Before / after — show a transformation with a punchy caption
Tips & how-to — one quick tip per Reel with captions on screen
Trend jacking — recreate a trending format with your own AI visuals
Quote & story clips — cinematic background video plus text overlay

Posting tips that help reach

Hook in the first 1-2 seconds — motion, a question, or a bold claim
Keep Reels short — 7 to 15 seconds often loops best
Post consistently — a steady schedule beats occasional bursts
Add a clear caption and 3-5 relevant hashtags, not 30
End with a reason to comment or save — engagement signals boost reach

How much does it cost?

Short vertical Reels — from US$0.15
HD videos — a little more per clip
Pay per video with tokens — no monthly subscription

That means a full week of Reels can cost less than a coffee. Batch-generate several clips in one sitting, schedule them out, and keep your Instagram active without burning hours on production.
