How do you maintain product consistency in AI-generated video ads?

Which AI models help maintain consistency?

Google AI for Developers offers two primary models for generating video: Gemini Omni Flash and Veo 3.1. Gemini Omni Flash is recommended as the default model for video generation. It is a fast, multimodal model for video generation and conversational video editing. Gemini Omni 1.1 Flash, a production-ready update, offers improved control over generative video.

Veo 3.1 is designed for specific capabilities, such as scene extension, last-frame control, and integration with existing pipelines. Google documents that Veo 3.1 generates video with native audio and supports features like video extension, frame-specific generation, and image-based direction. It is stable and generally available for production, offering professional-grade creative controls and multiple aspect ratios.

How do you keep visual elements consistent across scenes?

To maintain consistent characters, objects, and styles across multiple shots, Google recommends providing reference images to Veo 3.1. This approach helps direct scenes with a consistent aesthetic. Veo 3.1 also allows you to keep characters looking the same even as the setting changes, making it easier to tell a full narrative across multiple scenes. You can also achieve background and object consistency by maintaining the integrity of your setting and the objects within it.

Gemini Omni 1.1 Flash, an update to Omni Flash, offers improved control over generative video. It can analyze up to 10 seconds of prior context, a significant improvement from previous models that referenced only the final second. This allows you to reference up to three seconds of video when crafting a scene, helping to maintain visual context and character consistency based on video references. Additionally, assigning actions to timed segments in Veo 3.1 can efficiently create a full scene with multiple distinct shots, saving time and ensuring visual consistency.

How do you ensure smooth transitions and narrative flow?

Both Gemini Omni Flash and Veo 3.1 offer features to enhance narrative flow and transitions. Omni 1.1 Flash allows you to extend scenes up to 40 seconds with improved visual consistency and narrative flow, in 10-second increments. You can also set start and end frames to create smooth camera movements and transitions.

Veo 3.1 supports scene extension and frame-specific generation. It enables seamless transitions using "first and last frame" functionality, generating a natural video transition between a provided start image and end image, complete with audio. This workflow is ideal for creating multi-shot scenes with consistent characters engaged in conversation, leveraging Veo 3.1's ability to craft dialogue.

How do you maintain brand consistency with AI?

Gemini uses automated multimodal reviews to ensure AI-generated content matches specific brand guidelines at scale. This approach analyzes images and videos against detailed criteria, creating an automated review pipeline that catches brand inconsistencies before assets are published. Gemini analyzes the output against your brand guidelines and can automatically refine the generation prompt based on its specific findings.

To achieve success, it is crucial to translate vague brand concepts into exact, machine-readable data that the AI can explicitly measure. The evaluation stage can only catch what you have defined, meaning your guidelines need precision. By sampling keyframes throughout a video's duration, Gemini verifies that brand elements remain accurate from the opening frame through the conclusion. Google suggests planning for three to five iteration cycles before an asset meets all your brand requirements.

What resolution and quality options are available?

Both Gemini Omni 1.1 Flash and Veo 3.1 support high-resolution video output. Omni 1.1 allows you to upscale your final projects to 4K resolution for a polished, professional look, generating polished 1080p or 4K outputs that are ready for professional production.

Veo 3.1 also generates videos in 1080p and 4K with state-of-the-art upscaling. It offers professional-grade creative controls, multiple aspect ratios, and rich synchronous audio. Veo 3.1 also supports vertical video generation, producing lively, dynamic clips that feel natural and engaging.

Common questions

What is Gemini Omni Flash?

Gemini Omni Flash is one of two models offered by the Gemini API for video generation. It is recommended as the default model. It is a fast, multimodal model for video generation and conversational video editing.

What is Veo 3.1 used for?

Veo 3.1 is a model for generating video with native audio, used for specific capabilities like scene extension, last-frame control, or integration with legacy pipelines. It supports features such as video extension, frame-specific generation, and image-based direction. Veo 3.1 is stable and generally available for production, offering professional-grade creative controls, multiple aspect ratios, and rich synchronous audio.

How long can AI-generated videos be extended?

With Gemini Omni 1.1 Flash, you can extend scenes up to 40 seconds with improved visual consistency and narrative flow. Videos can be extended in 10-second increments up to this total cumulative length.

How can I ensure my brand guidelines are followed?

You can ensure brand guidelines are followed by using Gemini's automated multimodal reviews. This system analyzes images and videos against detailed criteria, catching inconsistencies. It requires translating vague brand concepts into exact, machine-readable data for the AI to measure. Your guidelines need precision, as the evaluation stage only catches what you have defined.

How many iterations are typically needed for brand compliance?

Google suggests planning for three to five iteration cycles before an AI-generated asset meets all your brand requirements. This iterative process allows for refinement based on Gemini's specific findings and ensures alignment with detailed brand guidelines.
