AI video generator made for 9:16 vertical
Most AI video models still think in widescreen. Cropping a 16:9 clip into 9:16 cuts off the faces you paid to generate.
AlphaDrama plans shots for a phone from the start: close-ups, stacked action, burned-in captions, and a 9:16 file you do not have to reframe.
Example: 60-second 9:16 episode: open on Emma's face in a gala, no wide shot, captions on, end on Ethan's hand stopping the door.
Framing that survives a phone screen
Vertical coverage lives in mediums and close-ups. Wide establishing shots waste the middle of the glass. The storyboard pass writes for that: eyes, hands, a doorway, not a panoramic skyline.
Captions are part of the picture
A large share of TikTok, Reels and Shorts plays with the sound off. Captions are generated with the voice track and sit in the safe area, not over the face.
- 9:16 export as the default
- Dialogue and narrator captions on the same timeline
- A horizontal export later if you need YouTube long-form
Drama and product ads use the same canvas
A short-drama episode and a TikTok Shop ad are both 9:16 stories. One has a cliffhanger; the other has a cart. The camera rules are the same: start close, cut often, end on a face or a product.
What not to do with vertical
Do not generate widescreen and hope a crop will save it. Do not put important action at the extreme top or bottom where UI chrome sits. Do not use tiny captions that vanish on a budget Android.
Platforms that take the same file
TikTok, Instagram Reels and YouTube Shorts all take a 9:16 MP4. Make the episode once. Change the caption and the first-comment hook per platform; do not remake the picture unless a test asks for it.
How it works
Start with a story or a product
Paste a chapter, an outline or a one-line idea. For an ad, add product photos or a product link.
We cast, storyboard and voice it
Characters get fixed looks, scenes get sets, and the script is split into shots with voices and captions.

Frequently asked questions
Is 9:16 the only aspect ratio?
It is the default for short drama and social ads. You can also export a wider file from the same project when a listing or long YouTube video needs it.
Will a 16:9 AI clip work if I crop it?
Usually not. Faces and text get cut. Generate vertical coverage from the start.
Are captions included?
Yes. Captions are burned in and timed to the voice.
What resolution should I export?
A 1080×1920 MP4 is the usual upload for TikTok, Reels and Shorts. Check each app if you need a different size.
