Key Takeaways
- ✓Reference Images Over Text Prompts: Create detailed reference images in Nana Banana Pro for each character, setting, and prop before generating video clips. This ingredients-to-video approach ensures visual consistency across all eight-second segments, unlike text-to-video which produces inconsistent results.
- ✓Four-Step Production Framework: Start with a strong original concept, build a storyboard with scene descriptions and dialogue using ChatGPT, generate reference images for each scene in Nana Banana Pro, then create eight-second clips in Veo 3.1 Flow and edit together in iMovie or CapCut.
- ✓AI Amplifies Expertise, Not Ideas: AI tools accelerate execution for domain experts but cannot generate creative concepts independently. The taste and original idea must come from the creator. AI excels at refining solutions, not identifying what solution to build in the first place.
- ✓Scene-by-Scene Image Building: Work through each scene systematically, asking ChatGPT what reference images are needed, generating Nana Banana prompts, and feeding previous character images to maintain facial consistency while updating clothing or settings. Total production cost remains under two dollars for complete videos.

Notable Moment
The creator spent ten hours on a single scene trying to make both characters speak dialogue simultaneously, eventually discovering the workaround required killing one character off-screen so the AI would allow the remaining character to deliver lines independently.
Episode Transcript
Over the holidays, I spent over thirty hours creating a two minute video ad using VO 3.1 and Nano Banana Pro, and I developed a process that could have cut that down to hours. And I'm gonna give you that process, four steps that you can use to create a professional looking AI video in hours. All of that and more on this episode of Marketing Against the Grain. Before we get into today's show, here's a quick word from HubSpot. Cutting your sales cycle in half sounds pretty incredible, but that's exactly what Sandler training did with HubSpot. They used Breeds, HubSpot's AI tools, to tailor every customer interaction without losing their personal touch. And the results were pretty incredible. Click through rates jumped 25%. Qualified leads quadrupled, and people spent three times longer on their landing pages. Go to hubspot.com to see how Breeze can help your business grow.

This is my first real attempt. I would say, like, twenty, twenty five hours. Okay. So it's, like, half a week's worth of time to make this video. With the tips that you've learned, how much time do you think it would take you to do a different version again? A couple of hours. Okay. So it's saving you twenty hours. It's saving you, like, eighty days max. A lot of hours. Yeah. There's, like, one specific thing that really drove me crazy. I'll tell you what it was after the video plays.
