How to Bulk Generate Veo Videos in Google Flow

Short answer: Google Flow runs one request at a time from its prompt box, and each request can make one or more clips. Its built-in Agent can also make several variations of one idea when you ask. To run a long list of different prompts, you can submit them one by one, or use a Chrome extension such as Flow Automation, which runs a CSV of prompts through your own Flow account and saves every render into dated folders. Whichever way you do it, every clip uses your own Flow credits: per Google, Veo 3.1 Fast costs 20 credits per generation and Quality costs 100, so plan the batch before you press start.

What you need before you batch anything

Google's help pages list these requirements for Google Flow:

• You must be 18 or older, with your age verified.
• You must be in a supported region. A VPN won't work.
• Google's "Get started" page says you need a Google AI Plus, Pro or Ultra plan. Its credits page says everyone gets 50 Flow credits a day, with or without a plan. The two pages don't fully agree, so check your own account.
• A Chromium browser such as Chrome or Edge is recommended on desktop.

What a batch really costs in credits (2026)

Google's credit table is the most important thing to read before a big run. These costs are for non-Ultra subscribers unless noted:

Two details catch people out:

1. Costs are per generation, not per request. Google says a single request "may generate 2 videos". If your settings make two clips per prompt, you pay twice.
2. Failed generations are free. Google says you are not charged credits for failed generations.

How many credits you get

What 1,000 credits buys

So a 50-clip batch on Quality needs 5,000 credits, while the same batch on Fast needs 1,000. Google notes that costs "are evolving fast", so check the current price in the prompt box settings before each big run.

Flow slows you down after heavy use

Google says it may rate-limit generations "to balance the available resources for all users and prevent abuse of our platform". After many generations in a day, "the number of generations you can make within a minute will decrease". If you see "You're requesting generations too quickly", that's the limit. Any batch method has to live with it, and a good one paces itself.

Step 1: Write your shot list before you open Flow

The biggest time sink in a batch isn't generating. It's thinking up the next prompt while the last one renders. So write every prompt first, one row per clip.

Use Google's own prompt order. Google's Ultimate prompting guide for Veo 3.1 gives this formula:

[Cinematography] + [Subject] + [Action] + [Context] + [Style & Ambiance]

• Cinematography: the shot and the camera move. For example, "close-up, slow dolly in".
• Subject: who or what we see.
• Action: what they do.
• Context: where it happens.
• Style and ambiance: the light, the look and the mood.

Then add the sound. Google suggests putting dialogue in quotation marks, writing effects as "SFX: …", and describing the background as "Ambient noise: …".

Example row: Close-up, slow dolly in. A barista pours latte art into a white cup. Small sunlit café, morning. Warm film look, soft grain. SFX: milk steaming. Ambient noise: quiet café chatter.

Tips for the sheet:

• Put one clip per row, so a spreadsheet exported as CSV works for any batch tool.
• Add columns for the model and the aspect ratio if your tool supports them per row.
• Group clips that share a look, so you can review them together.
• Describe what you want instead of what you don't. Google's example: say "a desolate landscape with no buildings or roads" rather than "no man-made structures".

Step 2: Draft in Fast, finish in Quality

Because Quality costs five times Fast per generation, a simple habit saves a lot:

1. Run every row in Fast (or Lite) first.
2. Pick the winners.
3. Re-run only the winners in Quality.

On a Pro plan, that's the difference between 10 finished clips a month and 50 drafts plus a few finals.

Step 3: Pick how you'll run the batch

Option 1: One by one in the prompt box (free)

Paste a row, generate, wait, download, and repeat.

• Good for: small batches of 5–10 clips.
• Downsides: each clip needs its own submit, wait and download. For 50 clips, that's 50 rounds of the same clicks, and downloaded files get generic names that don't tell you which prompt made them.

Option 2: Ask Flow's built-in Agent for variations (free)

Flow's Agent can "create multiple variations of an asset at once" when you ask in chat, and it saves everything to your open project.

• Good for: many takes on one idea, for example 10 lighting variations of the same shot.
• Downsides: media it generates still uses your credits, and Google says there's a daily quota on Agent queries. It's built for chat, not for a spreadsheet of different prompts with a different model per row.

Option 3: Use Flow Automation to run a CSV queue

Flow Automation is a Chrome extension from Extino that drives the Flow interface for you. It works in the Chrome side panel next to Flow. It selects the model, applies your settings, submits each generation, waits for the render and downloads the finished file.

• Five modes in one queue: Text to Video, Create Image, Image to Video, Ingredients to Video (up to three reference images), and Frame to Frame for chained scenes.
• Model per task, not one model for the whole run. So Fast drafts and Quality finals can sit in the same queue.
• Paced batches: 10 tasks at a time by default, with a 60-second cooldown between batches.
• Organized output: files are saved into date-organized folders, with filenames built from the prompt, model, index and timestamp, plus any prefix or suffix you set.
• Good for: agencies, content marketers and AI filmmakers running dozens or hundreds of clips.
• Downsides, honestly: it uses your own Flow credits and doesn't bypass any Flow limit, so the credit maths above still applies. It needs a Google Flow account, it runs in Chrome, and it's a paid tool (from £2.99 a month, or £49.99 once).

Comparison

How to run a batch with Flow Automation, step by step

1. Install Flow Automation in Chrome and pin it to the toolbar.
2. Open Google Flow in the same browser, signed in to your own account, and open a project.
3. Open the side panel and load your CSV of prompts.
4. Set the mode and model for each task, or a default for the whole list.
5. Check the pacing settings. The default is 10 tasks per batch with a 60-second cooldown. You can also set how long a run lasts and how long it waits before resuming.
6. Set the file naming, for example a prefix with the client or project name.
7. Press start, and leave it running.
8. Collect your files from the dated folders. Each filename tells you the prompt and the model that made it.

Is it safe to use an automation extension with Google Flow?

It's a fair question to ask about any tool. Here's what we can say about Flow Automation specifically:

• It drives your own Flow session in your own browser. Every clip is made by Flow, on your account, with your credits.
• It doesn't bypass any Flow limit. If Flow slows you down or runs out of credits, so does the extension.
• It paces itself by default, in batches with a cooldown, instead of submitting as fast as it can.
• It needs no API keys, code or separate account.

No tool can promise how Google will treat automated use of its services. Read Google's terms and usage policies, keep your batches reasonable, and stay within your plan. Flow Automation is an independent tool and isn't affiliated with or endorsed by Google.

Frequently asked questions

Can Google Flow generate videos in bulk? Flow runs one request at a time from the prompt box, and a request can make more than one clip. Its Agent can make several variations of one idea. To run a long list of different prompts unattended, you need a batch tool such as a Chrome extension.

How many credits does Veo 3.1 cost in Google Flow? Per Google Flow Help, Veo 3.1 Fast costs 20 credits per generation (10 on Ultra), Quality costs 100, and Lite costs 10 (5 on Ultra). Costs are per generation, not per request.

How many Veo videos can I make with Google AI Pro? Google AI Pro adds 1,000 Flow credits a month, on top of 50 a day. That's about 10 Quality clips or 50 Fast clips from the monthly credits.

Why does Flow say "You're requesting generations too quickly"? Google rate-limits generations to balance resources and prevent abuse. After many generations in a day, it lowers how many you can make per minute.

Do failed generations use credits? No. Google says you are not charged credits for failed generations.

Does Flow Automation need an API key? No, not for its main function. It runs in your own browser on your own Google Flow account, with no API keys or code. Automatic prompt generation is optional, and you can add your own API key if you want it.

Does Flow Automation get around Flow's limits or credits? No. It drives your own Flow session and uses your own credits, and it doesn't bypass any Flow limit.

What's the difference between Flow Automation and Whisk Automation? Both are Extino extensions that run on Google Flow. Flow Automation leads with video: five generation modes, a model chosen per task, and dated auto-downloads. Whisk Automation leads with reusable node workflows for image sets, where a character reference is uploaded once and reused.

Try it on your next shot list. If your batches run past a handful of clips, Flow Automation runs the whole list in your own Flow account and files every render for you. It's from £2.99 a month, and you can cancel from inside the extension. See Flow Automation.
