Class 11 · 2-Year Batch — AI Performance Ad
One 45-second performance ad for Vedantu Learning Centres' Class 11 two-year JEE/NEET batch, written and produced with AI. From a single script it shipped as 16 finished videos: English, Tamil, and two Telugu versions (Andhra Pradesh and Telangana), each in four sizes.
Class 11 is when JEE/NEET preparation quietly slips. The ad had to meet that moment first (half the year gone, the plan not working) and only then make the offer: you're not alone, and there's still time.
One emotion-tagged script. AI-generated students in the first half, real Vedantu Learning Centre footage in the second, kinetic on-screen text, and a region-specific end card. Adapted for Tamil Nadu, Andhra Pradesh and Telangana, in 16:9, 9:16, 1:1 and 4:5.
16 finished videos from one script: four versions in four sizes each, cut from the same AI shots and real footage.
A performance ad for Vedantu Learning Centres' Class 11 2-Year Batch (JEE / NEET): one master film, built to ship in English, Tamil and Telugu and in every size a media buyer asks for.
The film is a hybrid by design. The emotional first half (a student alone with a test paper at night) is AI-generated, so it can be re-shot and re-cast quickly. The second half is Vedantu's own Learning Centre footage, so the proof is real.

Times are for the English master; the Tamil and Telugu versions run 2–3 seconds longer to let the voice-over breathe.
Tamil and Telugu were adapted, not just translated. ChatGPT produced the first drafts; Gemini reviewed and tightened them. The tightened versions ran about 30% shorter than the literal drafts and read as conversation. English words students actually say (JEE, NEET, doubts, classroom) stay in English, in Latin script.
Each language got its own voice, cast on ElevenLabs v3 with emotion tags, and the regional cuts got a new, longer music bed. No new video was generated: the same AI shots and real footage were re-timed to each voice-over.
Every language ships in four sizes: 16:9 (1920×1080), 9:16 (1080×1920), 1:1 (1080×1080) and 4:5 (1080×1350). The AI video model keeps the shape of its start frame, so the key shots were generated in both 3:2 and 2:3. The 3:2 clips feed the 16:9 and 1:1 cuts, the 2:3 clips feed 9:16 and 4:5.
On-screen text, labels and end cards are re-laid out for each size and rendered as transparent overlays, so a fix to one line of copy re-renders all 16 videos.
