AI Video Generator for Instagram Reels

A Reel is a 9:16 vertical video, and that single constraint decides which AI model you can actually use. Across VdoBloom's 54 video model variants (14 model families), aspect-ratio control is not universal: text-to-video models let you pick 9:16 outright, and so do a few image-to-video models — Runway Gen-4 Turbo, Grok Imagine Video 1.5, Gemini Omni Image-to-Video and Vidu 2.0 — while the rest expose no aspect selector at all and inherit the shape of the photo you upload.

Two tools are purpose-built for this surface. Creator Reel takes a topic, one photo of you and a target length — 30 seconds, 1, 1.5 or 2 minutes — writes the script, films it as a run of 4–15 second talking clips, transcribes the resulting audio and burns word-timed kinetic captions into a 1080×1920 frame. Viral Video works the other way: give it a topic and it invents the hook, writes the caption with hashtags, builds the generation prompt, then renders the clip on whichever model you selected.

Everything else in the app exports the same postable MP4 — 46 one-click effect tabs, plain image-to-video, and Clip Studio for turning something long into vertical cuts. Downloads on the free plan carry a VdoBloom watermark; on a paid plan the same file downloads clean.

What this tool does

  • Instagram's Reels spec is a 9:16 vertical video at 1080×1920 — the exact frame VdoBloom's Creator Reel renders.
  • Creator Reel offers four finished lengths — 30 seconds, 1 minute, 1.5 minutes and 2 minutes — assembled from 4–15 second clips, capped at 12 clips per reel.
  • Creator Reel's captions are word-timed: it transcribes each clip's own voiceover with word-level timestamps and burns kinetic ASS captions from that, so caption timing is measured rather than estimated.
  • Choose 16:9 in Creator Reel and one job returns four files — 9:16 captioned, 9:16 clean, 16:9 captioned, 16:9 clean. Choose native 9:16 and it returns two: captioned and clean.
  • Creator Reel scripts and speaks in 6 languages — English, Hindi, Tamil, Telugu, Spanish, Arabic — with 7 English accent options including Indian English.
  • Creator Reel ships 3 reel formats (Talking Head, Hot Take, Listicle) and a 12-shot camera library — eye-level, close-up, low-angle, high-angle, standing wide, over-shoulder, side profile, handheld push, walk-and-talk, dolly push-in, orbit, pull-back — settable per shot.
  • The Viral Video tool writes the caption for you with exactly 12 lowercase hashtags: 4 topic-relevant, 4 all-time popular and 4 currently trending, alongside an idea line kept under 13 words.
  • 9:16 is a selectable aspect ratio on Runway Gen-3, Gen-4 Turbo and Gen-4.5, Kling V3 Turbo, Kling 3.0, MiniMax H3, Seedance 2 / 2.5 / 1.5 Pro, Wan 2.7, PixVerse v3.5–v6, Vidu Q1/Q2/Q3, SkyReels V4, Gemini Omni, Grok Imagine Video, P-Video and Veo 3.1.
  • Image-to-video models — Kling 2.6, Wan 2.7 I2V, Wan 2.6 Flash, MiniMax H3 I2V, Hailuo 2.3, SkyReels V4 I2V, Bytedance V1 Lite — expose no aspect-ratio control; the clip inherits the shape of the photo you upload, so start from a vertical still. Runway Gen-4 Turbo, Grok Imagine Video 1.5, Gemini Omni Image-to-Video and Vidu 2.0 do expose one.
  • Veo 3.1 and Gemini Omni expose only 16:9 and 9:16 — neither offers a 1:1 square option.
  • Free-plan downloads carry a VdoBloom watermark; a paid plan downloads the identical file watermark-free.

How it works

  1. 1.Pick a reel format and length

    Choose Talking Head, Hot Take or Listicle, then a target length of 30 seconds, 1, 1.5 or 2 minutes. The length decides how many beats the script engine plans — it aims for roughly 13 spoken seconds per beat and never exceeds 12 beats.

  2. 2.Upload one identity photo and set the language

    Creator Reel needs a clear photo of the person on camera and a ticked consent box before it will use it. Pick from English, Hindi, Tamil, Telugu, Spanish or Arabic; if you pick English you also get 7 accent options, Indian English among them.

  3. 3.Review the storyboard before committing

    Creator Reel runs as draft → review → build. The storyboard preview is a flat 20-credit step that shows you the planned shots so you can swap camera angles or rewrite a beat before paying for the full render.

  4. 4.Choose the render model

    Six audio-capable image-to-video models are offered: Seedance 2 (best quality), Seedance 2 Fast, Seedance 2 Mini (cheapest), Seedance 1.5 Pro (budget), Gemini Omni and WAN 2.7. All of them speak the script lines natively, which is what makes the transcript-driven captions possible.

  5. 5.Export 1080×1920 and post

    The primary output is the 9:16 captioned cut at 1080×1920. Grab the clean version too if you'd rather add your own text in Instagram, and use the Viral Video tool separately if you want the AI to write the caption and hashtags.

Frequently asked questions

What aspect ratio and resolution should an Instagram Reel be?

9:16 vertical at 1080×1920. Creator Reel renders exactly that. If you generate a Reel with a plain text-to-video model instead, pick 9:16 in the aspect selector — it's available on Runway, Kling, Seedance, Wan 2.7, PixVerse, Vidu, SkyReels V4, MiniMax H3, Gemini Omni and Veo 3.1. Most image-to-video models — Kling 2.6, WAN 2.7 I2V, WAN 2.6 Flash, MiniMax H3 I2V, Hailuo 2.3, SkyReels V4 I2V and Bytedance V1 Lite — have no aspect selector and copy the shape of your uploaded photo, so upload a vertical still. Runway Gen-4 Turbo, Grok Imagine Video 1.5, Gemini Omni I2V and Vidu 2.0 do offer one.

How long can an AI-generated Reel be?

It depends on the tool. Creator Reel stitches multiple clips and offers 30 seconds, 1, 1.5 or 2 minutes. A single model generation is much shorter: most video models cap at 15 seconds per job, Seedance 2.5 goes to 30 seconds at 480p or 720p from the Seedance Effects tab, and Vidu Q3 does 16 seconds with audio. Instagram has raised its own Reels length cap more than once, so check the current limit in the app before planning a long cut.

Do the captions come burned into the video?

Yes, in Creator Reel. It extracts the audio from each generated clip, transcribes it with word-level timestamps, and burns kinetic captions plus intro and punchline cards into the frame before export. Clip Studio does the same thing for clips cut out of a long video. Every Creator Reel job also returns a clean, caption-free version of the same edit.

Can I make Reels in Hindi or Tamil?

Creator Reel scripts and speaks in English, Hindi, Tamil, Telugu, Spanish and Arabic, and English has 7 accent options including Indian English. Separately, the Translate & Dub tool covers 12 languages in its picker, 7 of them Indian: Hindi, Tamil, Telugu, Bengali, Marathi, Kannada and Malayalam.

Will my Reel have a VdoBloom watermark?

On the free plan the download carries a watermark. On a paid plan the same generated file downloads without one. If your browser reports the Asia/Kolkata timezone or a Hindi locale, VdoBloom prices plans in rupees and checks out through Razorpay instead of USD.

I don't want to show my face — what should I use?

Creator Reel requires an identity photo, so use Viral Video or plain text-to-video instead. Viral Video takes a topic, writes the hook and the 12-hashtag caption, and renders on any text-to-video model at 9:16. The 46 effect tabs are another faceless route — Product 360, Comic to Video, Music Video and the rest all start from a still image.

What is the cheapest way to generate a vertical clip?

Reading the live credit table: Bytedance V1 Lite image-to-video is 4 credits for 5 seconds at 480p and 9 credits at 720p; P-Video is 8 credits for 5 seconds at 720p; Grok Imagine Video 1.5 is 8 credits for 5 seconds at 480p and 15 at 720p. Kling V3 Turbo bills per second at 7.2 credits per second in 720p, so a 3-second clip costs 22 credits. Veo 3.1 Fast is a flat 40.
