Multimodal Inputs
Use text, image, audio, and video together instead of limiting direction to prompts and still-image references.
Gemini Omni 1.1 Flash goes beyond one-shot AI video generation. It understands text, images, audio, and video, supports conversational editing, preserves more context when extending scenes, accelerates draft iteration, and delivers up to 4K output. Veo 3.1 remains strong for cinematic generation, but Omni offers the broader end-to-end creative workflow.
Gemini Omni 1.1 Flash is our overall pick because it covers more of the production journey: multimodal prompting, reference-video guidance, conversational editing, context-aware scene extension, low-cost 360p drafts, and 4K finishing. Choose Veo 3.1 mainly when your priority is a dedicated cinematic generator with strong native dialogue, synchronized effects, and reference-image control. For creators who want to move from idea to revision to final output in one flexible workflow, Omni has the clearer advantage.
Unlike a generator centered mainly on prompts and reference images, Gemini Omni 1.1 Flash accepts text, images, audio, and video. It can generate high-resolution video with audio and then refine the result through natural-language instructions. That makes Omni more useful when a project begins with mixed assets or requires several rounds of targeted editing.
Try Gemini Omni 1.1 FlashOmni 1.1 can produce lightweight 360p previews up to 60% faster than its own 720p workflow and at one-third of the cost, according to Google. Creators can compare variations first, then move the strongest concept to 1080p or 4K. Veo 3.1 Fast improves generation speed, but Omni's explicit draft-to-final pipeline gives iterative teams a clearer way to control time and rendering cost.
Start Creating OnlineOmni 1.1 analyzes up to 10 seconds of previous context and extends video in 10-second increments to a cumulative 40 seconds. Veo 3.1 can build a sequence beyond one minute, but each new extension is guided by only the final second of the preceding clip. Omni's wider context window gives it an important continuity advantage when preserving dialogue, movement, framing, and narrative intent.

Change an existing result with natural-language instructions instead of rebuilding every shot from the beginning.
Analyze up to 10 seconds of earlier footage to preserve more visual and narrative context while continuing a scene.
Prototype quickly in 360p, compare concepts, and finish the selected direction in 1080p or 4K.
Gemini Omni 1.1 Flash should be the default for most iterative production workflows. Veo 3.1 remains a worthwhile specialist option when cinematic generation and audio performance outweigh editing flexibility.
Omni 1.1 Flash wins when creation is a process rather than a single render. Its combination of mixed inputs, targeted revisions, faster previews, richer extension context, and 4K delivery reduces the need to move between separate generation and editing tools.
Generate lightweight 360p variations, compare directions quickly, revise them through conversation, and reserve higher-resolution rendering for the ideas worth finishing.
Video and audio inputs make Omni more practical for transforming, continuing, or refining material you already have—not only generating a fresh clip from a prompt.
First-and-last-frame control, reference video, contextual extension, editing, native audio, and 4K output sit inside one connected creative workflow.
Omni leads in the categories that affect repeated production work: input range, revision control, reference-video use, extension context, and structured draft-to-final iteration.
| Feature | Veo 3.1 | Gemini Omni 1.1 Flash |
|---|---|---|
| Primary Focus | Cinematic text-to-video and image-to-video generation | Multimodal generation and conversational editing |
| Supported Inputs | Text prompts, source images, up to 3 reference images, and Veo video for extension | Text, image, audio, and video |
| Video with Native Audio | Yes, with a strong focus on dialogue, effects, and ambient sound | Yes, within the same multimodal creation and editing workflow |
| Maximum Output Resolution | Up to 4K in supported Veo workflows | Up to 4K |
| Fast Draft Mode | Veo 3.1 Fast model available | 360p previews; up to 60% faster than 720p |
| Conversational Video Editing | Not its primary API workflow | Yes |
| First and Last Frame | Yes, including accompanying audio | Yes, integrated with broader editing controls |
| Reference Guidance | Up to 3 reference images for a character, object, or scene | Up to 3 seconds of reference video plus multimodal context |
| Scene Extension | Uses the final second; connected extensions can exceed one minute | Uses up to 10 seconds of context; 10-second increments up to 40 seconds total |
| Best For | Cinematic ads, narrative scenes, and audio-rich one-shot generation | End-to-end production, iterative editing, prototypes, explainers, and flexible creative apps |
Gemini Omni 1.1 Flash is the better all-round choice for multimodal creation, conversational editing, fast preview iterations, context-aware extensions, and 4K finishing. Veo 3.1 remains a strong specialist for cinematic generation, native dialogue and sound, reference-image consistency, and longer cumulative extensions.
Gemini Omni 1.1 Flash is Google's multimodal generative video model. It accepts text, image, audio, and video inputs, produces video with audio, supports conversational editing, first-and-last-frame interpolation, scene extension, 360p previews, and output up to 4K.
Veo 3.1 is best suited to cinematic text-to-video and image-to-video creation, especially when a shot needs realistic motion, stronger cinematic-style understanding, character consistency, natural dialogue, synchronized sound effects, or ambient audio.
Yes. Both generate video with audio. Veo 3.1 puts particular emphasis on richer native audio, including natural conversations, synchronized effects, and ambience. Audio quality still depends on prompt clarity and scene complexity.
Veo 3.1 is the stronger default when the goal is a polished cinematic animation from a source image. Omni 1.1 Flash is more attractive when that image is only one part of a broader workflow involving video references, audio, conversational edits, or repeated variations.
Yes. Both can generate a continuous transition between a specified starting and ending frame. This is useful for camera orbits, zooms, scene transformations, transition shots, and seamless loops.
Omni 1.1 Flash analyzes up to 10 seconds of earlier footage, which can help continuity inside shorter controlled extensions. Veo 3.1 bases each extension on the final second but can connect generations into videos lasting a minute or more. Choose based on context depth versus total extendable duration.
Gemini Omni 1.1 Flash supports polished 1080p and 4K output. Veo 3.1 also reaches 4K in supported products and workflows, although available resolutions, aspect ratios, and controls may vary by platform or API endpoint.
There is no universal cross-model speed figure because render time changes with resolution, duration, traffic, and platform. Google states that Omni's 360p preview mode can be up to 60% faster than Omni's own 720p mode. Veo 3.1 Fast is the speed-oriented Veo option.
Yes. Media.io brings multiple AI video workflows into one browser-based creation environment, making it easier to test a prompt or image across available models and choose the output that best matches your project.
