How we built it

This entire spec ad was created with just ONE SINGLE PROMPT using Sora 2 Pro on OpenArt AI, fully generated through a text-to-video workflow. I barely made any manual edits, only tweaked the smartphone UI a bit using Nano Banana in Photoshop, then added the ending logo. All the music and voice-over came directly from Sora, and I only added some subtle sound effects for realism. For post-production, I used CapCut to refine timing, adjust audio balance, and insert the final logo. Then, I upscaled the video in Topazlabs to enhance resolution and detail. The concept was to create a Thai-style spec ad for CIMB Niaga Bank, inspired by the playful, emotional tone of Thai commercials.
