Google Veo vs Omni vs Flow: Which One to Use, Plus Alternatives

For 1080p text-to-video or image-to-video, use Veo 3.1. Use Veo Omni if you want to give it text and images together, or if you need 4K output. Pick Flow if you want to work inside Google's own filmmaking app, with scenes and shots instead of single clips. If you want an alternative to Google, try Kling 3.0 for multi-shot scenes and a 4K mode, or Seedance 2.5 for clips up to 30 seconds with sound.

To run Veo next to its rivals under one subscription, you can try Veo 3.1 on Moleculs.

Veo 3.1, Veo Omni and Flow: two models and one app

Google uses all three names in the same announcements, so they get mixed up. They split like this:

• Veo 3.1 is a model. You give it a prompt or a reference image, and it returns a video clip.
• Veo Omni is also a model. It takes text and images in one request and outputs up to 4K.
• Flow is an app. It generates nothing itself: it's Google's interface for making short films, with Veo underneath.

So "Veo or Flow" is a choice between a model and a workspace built around it. "Veo 3.1 or Veo Omni" is a choice between two models, and it depends on what you feed in and what resolution you need.

How to choose: input type, resolution, clip length, sound and access

Check five things, in this order:

1. Input: text only, one reference image, or several references at once.
2. Resolution: 1080p is enough for social media and most web use. 4K matters for big screens, cropping and post-production.
3. Clip length: most models produce short clips. If you need one continuous shot that runs long, your list gets much shorter.
4. Sound: some models generate audio with the picture. For others you add sound afterwards.
5. Access: the vendor's own app, or an aggregator that hosts several models.

That usually leaves one or two candidates. Give the same prompt to each and compare the results.

Comparison table

Veo 3.1: text-to-video and image-to-video with a 1080p option

Who it's for: people who need a realistic clip from a written description, or want to bring a still frame to life.

Veo 3.1 has two modes. In text-to-video, you describe the shot: camera movement, light, subject, mood. In image-to-video, you give it a reference image and it animates that image. Use this mode when the composition has to stay fixed, as with a product shot, a character design or a specific location. Output goes up to 1080p.

Whether sound is generated depends on where you run the model, so check the model page before you spend a run.

Where it's limited: it's a 1080p model. If the clip is going to a large screen or you plan to crop it heavily, look at Veo Omni. Clips are short, as with most models in this class.

When not to use it: skip it if you need 4K output or want to mix text and image references in one request. That's what Veo Omni is for.

For image-to-video, the first frame decides most of the result. If you don't have a good photo, generate a first frame with an image model and animate that. Nano Banana 2 and Seedream v4.5 are both options for it.

Veo Omni: multimodal input and output up to 4K

Who it's for: people who already have reference material (a style frame, a character, a product) and need the result at high resolution.

Veo Omni accepts text and images in the same request, so you can describe the scene and show what things should look like. Output goes up to 4K, which is the main reason to pick it over Veo 3.1.

Where it's limited: higher resolution can cost more per run, so check the price before you start. While you're still testing ideas, 4K only slows you down.

When not to use it: while you're drafting. Try your prompts on Veo 3.1 at 1080p first, then switch to Omni for the final render once the shot is right. That saves budget on any project that takes more than a few attempts.

Google Flow: Google's filmmaking app built around Veo

Who it's for: people who want to make a short film in one place and are happy to stay in Google's ecosystem.

Flow is built around scenes and shots instead of single generations. You assemble a sequence and keep the project together. If the result is a story with several shots, not one clip, this structure helps.

Where it's limited: Flow is a Google product and runs Google's models, so you can't test Kling or Seedance on the same prompt there. Access depends on your Google account and plan, and Google changes its plans. Check current terms on Google's site.

When not to use it: if you need a single clip for a post, or want to compare vendors before committing. A standalone model is faster for one-off work.

Kling 3.0: multi-shot video, element references and 4K mode

Who it's for: people building short sequences where the same character or object has to stay recognisable from shot to shot.

Kling 3.0 generates multi-shot video. You can pin specific elements with references, so a character's face or a product's shape stays consistent. It also has a 4K mode, which puts it next to Veo Omni on resolution. A separate image-to-video mode animates a photo with camera movement.

Where it's limited: multi-shot and element references mean more settings to manage, so your first attempts may take longer than with a single-prompt model. If you use Kling directly, you need a separate account and plan on its site.

When not to use it: for a single atmospheric shot with no recurring elements. A simpler text-to-video model such as Veo 3.1 is enough there.

Seedance 2.5: clips up to 30 seconds with sound and close reference matching

Who it's for: people who need one longer continuous clip with audio, or need the output to follow a reference closely.

Seedance 2.5 makes clips up to 30 seconds with sound, which is long for this class of model. It follows references closely, which matters when a client has signed off on a look and doesn't want the model to improvise.

Where it's limited: a failed 30-second attempt wastes more than a failed short one. Test the motion on a shorter clip first.

When not to use it: if you need 4K. The catalogue doesn't list a 4K mode for Seedance 2.5, so look at Veo Omni or Kling 3.0 instead. Its siblings Seedance 2.0 and Seedance 2.0 Mini cover text-to-video, image-to-video and multimodal references, and Mini is the faster, cheaper option for drafts.

Moleculs: Veo and its alternatives under one subscription

Who it's for: people who want to compare Veo with Kling and Seedance without opening three accounts.

Moleculs is an aggregator. One interface and one subscription give you models for text, images, video and sound. The video lineup includes Veo 3.1 (text-to-video and image-to-video), Veo Omni, Kling 3.0, Seedance 2.5 and 2.0, Wan 2.6, Hailuo 02, HappyHorse and Grok Imagine. Topaz Video Upscale is there too, for upscaling a finished clip up to 4x. Each model has its own cost per run in credits, shown next to the model. Check the full catalogue of video models with per-run costs before planning a project.

A quick test: run this rainy neon street prompt on Veo 3.1. Then send the same text to Kling 3.0 and Seedance 2.5 and compare.

Where it's limited: Moleculs doesn't build models. It gives you access to other companies' models, and the interface and settings can differ from Google's or Kling's own app, so some fine controls may be missing. There's no side-by-side view, so you run the comparison one model at a time. And Moleculs isn't Flow: there's no scene-based film editor.

When not to use it: if you've settled on Google and want Flow's way of building a film, go to Flow directly.

Free Veo alternatives: what you can get without paying

• Free Veo access: it comes up rarely, with tight limits, and Google changes its terms. Don't build a project around it.
• Vendor trials: some video model makers give new accounts trial credits on their own sites. Check the current terms on each site.
• Open weights: some open-weight video models can be run locally for free if you have a powerful GPU and some patience. Read the license first.
• Free plan on Moleculs: it has a quota of 5 credits. That covers a few runs of cheap text models, but video costs more per run than text, so it probably won't cover a clip. Check the catalogue first.

If price matters more than Veo quality, use cheaper models for drafts. Seedance 2.0 Mini, Wan 2.6 (720p/1080p, 5, 10 or 15 seconds) and Hailuo 02 Standard (512P/768P, 6 or 10 seconds) let you test motion and framing. Once the shot works, render it on Veo. For help with prompts, look through these prompt examples for Google models.

Which one to pick

• A single 1080p clip from a prompt or photo: Veo 3.1.
• Text and image references in one request, or 4K delivery: Veo Omni, after drafting on Veo 3.1.
• A short film built scene by scene, Google only: Flow.
• The same character across several shots: Kling 3.0.
• One long take with sound that sticks to the reference: Seedance 2.5.
• Comparing all of the above under one subscription: an aggregator such as Moleculs.
• No budget at all: open-weight models on your own hardware, or vendor trials. Expect limits.
