Zera Studio is an AI video editor for Android, made for creators who talk to the camera. Film yourself talking, pick the video, and Zera adds B-roll, motion graphics, zooms and word-by-word captions, timed to what you say. Every AI edit then opens on a real multi-track timeline, so you can change anything.

What to film
A video of you talking to the camera, up to 3 minutes: your face in the shot and your voice clear. Explain something, share a tip, tell a story. Zera builds the edit from your words, so music-only clips, scenery and screen recordings don't work well.

AI B-roll and motion graphics
Zera transcribes English, Hindi or Hinglish speech, works out what each line is about and adds:
• Stock B-roll from Pexels, where it fits what you say
• Motion graphics designed for your words: titles, lists, numbers and callouts
• Punch-in zooms on the lines that land
• Word-by-word captions
• A clearer voice, with background noise taken out (Denoise in the editor switches back to the original sound)
Every clip, graphic, zoom and caption is its own item on the timeline: trim it, replace it, move it or delete it.

Auto captions, word by word
• English, Hindi (Devanagari) or Hinglish in Roman letters, the way people type it
• Auto detect picks the language from the speech
• 28 animations, including Pop, Wave, Type, Reveal, Letter Drop, Glow, Scramble and Bounce
• Font, colour, glow and outline
• Fix any word before you export

A full editor
• Multi-track timeline for video, text, effects, overlays and music
• Keyframes, masking, filters and colour adjustments
• Speed from 0.25x to 4x
• Overlays and picture-in-picture
• Transitions, animated text and music with a visible waveform
• Crop and frame for any platform

Export
480p, 720p, 1080p, 2K or 4K, at 30 or 60 fps. No watermark, on the free plan too.

How credits work
Editing and export never cost credits. Credits are only for the AI features:
• AI B-roll: 15 credits for a 30-second reel, charged by the second
• Captions: 1 credit per minute (Hinglish: 3)
• AI image or AI background: 6 credits each
The cost is shown before a run starts, and a run that fails gives its credits back. Every new phone gets 50 credits once, enough for about 3 reels. The free version shows ads. Monthly plans remove the ads and add credits every month: the Basic plan's 300 credits make about 20 reels a month, or up to 50 AI images or backgrounds.

Who it's for
Talking-head creators, coaches and teachers, podcasters cutting short clips, small businesses talking about their products, and anyone posting Reels and Shorts.
