Flow Auto Pro: the complete guide
Queue a whole list of prompts into Google Flow and walk away.
Flow Auto Pro is a tab in the Erasio side panel. You paste in a list of prompts, press Run, and it types them into Google Flow one after another — waiting for each clip, removing the watermark if you asked it to, and saving every file with a name that sorts in the order you wrote it. This guide walks through it from the very beginning. You do not need to have automated anything before.
An Erasio account, signed in
A batch spends credits, so it needs to know who you are.
Google Flow open in a tab
Erasio drives the real page — flow.google.com.
A list of prompts
Typed, or in a .txt file, or in a spreadsheet.
Start here — four steps
The whole thing, before any detail. If these four steps make sense you can already use Flow Auto Pro; everything below is for when you want more control.
Open the tab
Click the Erasio icon, then Flow Auto Pro in the row of tabs under the header.
Open Google Flow
If you are not on it, the panel says so and gives you a button that opens it.
Paste your prompts
One idea per block, with a blank line between them. Watch the counter.
Press Run
A progress window opens. Leave the Flow tab open and go do something else.
What people use it for
- Making many clips from a list of ideas you already wrote down
- Turning a spreadsheet of scenes into finished video
- Long overnight runs you do not want to babysit
- Re-running the handful of prompts that failed, without redoing the rest
Writing your prompts
If you read only one section of this page, read this one. It is the thing everybody gets wrong the first time, and it takes ten seconds to get right.
The one rule: a blank line starts a new prompt
Everything else on this page is optional. This is not. Erasio splits your text wherever it finds an empty line — so three blocks separated by blank lines are three prompts, and the same three blocks typed without blank lines are one very long prompt.
A red fox running through tall grass at sunset. A city street in heavy rain, neon reflections. An empty beach at dawn, slow waves.

Choosing what to make
The “What to generate” dropdown decides everything that follows — the rest of the panel changes to match it. Each option explains itself in the list, but here they are side by side.
Text to Video
Start here if you are not sure.You describe the shot in words and Flow builds the whole clip. Reference images are optional.
Frame to Video
You give it a still picture and it animates it. Add a second picture to set the closing frame.
Ingredients to Video
You hand it several pictures, videos or characters and it composes a clip out of them.
Text to Image
The same as Text to Video, but it makes a still picture instead of a clip.
Image to Image
You upload pictures and the prompt describes how to change them.
Agent Automation · Video
Use this when normal runs get refused.Hands the whole request to Flow’s own assistant, which picks its own settings.
Agent Automation · Image
Use this when normal runs get refused.The same, for still pictures.
Step by step
The same journey as the quick start, with everything explained. Work down it with the panel open beside you.
Decide about the watermark first
It is the top card on Control, and it is first for a reason: it is the only choice here that changes what your batch costs.
- Off keeps Google’s file exactly as it arrives, watermark and all. This is the cheapest option.
- Sparkle and Veo are two different watermarks. Look at what your clip actually has and pick that one — the wrong engine simply leaves the mark in place.
- Switch it on and Erasio shows you the price right there, before you commit to anything.
Add reference pictures, if your mode uses them
Click the upload area, drag files onto it, or just paste a screenshot straight in with Ctrl+V.
- Erasio shows you which picture is going to which prompt before you start, so there are no surprises.
- “Match by filename” attaches a picture called maya.png to every prompt that mentions Maya, instead of handing files out in upload order.
- Whatever the settings say, writing a filename inside a prompt pins that exact file to it.
- If your mode does not use pictures, this section tells you so rather than letting you upload into nothing.
Write or import your prompts
Type them into the big box, or bring them in from a file you already have.
- One idea per block, blank line between each. The counter under the box tells you how many Erasio can see.
- “Upload .txt” reads a plain text file and splits it the same way.
- “Upload .xlsx / .csv” reads a spreadsheet — Erasio asks which column your prompts are in and shows you a preview before importing anything.
- Clear wipes the box, and asks first.
Re-run only what failed, with Prompt range
This card appears once you have more than one prompt, and it is the feature you will be most grateful for.
- Say three prompts out of thirty failed. Do not edit your list.
- Switch Prompt range on and set From 12, To 14.
- Only those three run. Their original numbering is kept, so the new files still sort next to the ones that worked the first time.
Check how the files will be saved
The Downloads card on Control, and the Downloads card in Settings.
- Auto rename saves each file as 003_your-prompt, so a finished batch sorts in the order you wrote it. Leave this on.
- “Save as one ZIP” holds everything until the run finishes and gives you a single archive instead of thirty separate downloads.
- Quality lives in Settings, and it matters more than it looks — see the note below.
Press Run, then leave it alone
A progress window opens on its own and names what each prompt is doing.
- The stages are Submitting, Waiting for Flow, Generating, Removing watermark, Saving. If a run looks stuck, this tells you where.
- You can hide the window and bring it back with the Progress button. Stop is always available.
- Keep the Flow tab open until it finishes. Close it and the batch stops with it — Erasio is driving that page, and it has nothing to drive without it.
- You can keep using your computer. Just leave that tab alone.
Every setting, in plain English
Most of these you will never touch — the defaults are chosen to work. Anything marked “Leave this alone” is safe to ignore until something specific goes wrong.
Generation
What each clip is, before anything else happens to it.
Aspect ratio
The shape of the frame. Only the ratios this mode actually offers are listed.
When it matters: Set 9:16 for phone-shaped video, 16:9 for widescreen.
Model
Leave this aloneWhich Flow model renders each prompt.
Outputs per prompt
How many clips Flow makes from each prompt.
When it matters: Still one credit per prompt however many it makes — but watermark removal is charged per file.
Clip length and chaining
This is where a list of separate clips can become one continuous sequence.
Clip length
How long each clip runs — 4, 6, 8 or 10 seconds.
A length marked “continue”
Takes the last frame of one clip and starts the next one from it, so your prompts flow into each other.
When it matters: Use it when your prompts describe one unfolding scene. The final prompt always uses the plain length.
Image chaining
The same idea for stills — “Reuse” edits the previous picture instead of making a new one.
Characters and voices
Only on the video and agent modes. This is Flow’s own cast, not files you upload.
Scan characters
Reads the characters already in your open Flow project. Press it once, with a project open.
Auto-add characters
Any prompt that mentions a scanned character gets that character attached, at exactly that word.
When it matters: Nothing is uploaded and nothing extra is charged — it uses what is already in your project.
Fallback character
Used for prompts that name nobody. Leave it on “None” to attach nothing.
Auto-add voices
Picks a Flow voice when a prompt names a speaker — one voice per prompt, so a multi-character script keeps its cast straight.
Downloads
Where your files end up and what state they are in.
Video / image quality
How large each saved file is.
When it matters: Choose 720p or 1k if you want watermarks removed. Higher qualities bypass Erasio entirely.
Auto rename
Leave this aloneNumbers each file so a batch sorts in order.
Save as one ZIP
One archive at the end instead of a download per file.
When it matters: Applies at 720p and 1k. Flow saves the higher qualities itself, so those still arrive one by one.
Save to folder
A subfolder of your Downloads folder.
When it matters: Chrome’s “Ask where to save each file” overrides this — turn that off if files land loose.
Pacing
The settings that keep a long batch from being throttled. Worth understanding even if you never change them.
Wait between prompts
A random pause in the range you set.
When it matters: Raise both numbers if Flow starts complaining. Flow’s abuse detection watches rhythm as much as volume, which is why the wait is random rather than fixed.
Prompts in flight
How many prompts may be waiting to be collected at once.
When it matters: 1 keeps a batch strictly one at a time, which is what makes it predictable. Raising it overlaps generating with collecting and pays off on long renders.
Retries per prompt
Leave this aloneHow many times a failed prompt goes back on the queue before it is given up on.
Flow compatibility
The card to reach for when everything suddenly breaks.
Refresh now
Pulls the current locations of Flow’s buttons from Erasio.
When it matters: Google reships Flow without notice. If every prompt starts failing, press this before reporting a bug.
What a batch costs
The same rule applies in all three tabs, and nothing here is charged twice.
Generating one prompt
However many outputs it produces.
Removing a watermark from a video
Only if you switch removal on.
Removing a watermark from an image
Only if you switch removal on.
Put together
If a batch runs you out of credits it stops and tells you which prompt it stopped on and how many credits that prompt needed — it will not leave a progress bar frozen with no explanation. Prompts that already finished are not re-charged when you run the rest.
If something goes wrong
Find your symptom in the left column. Almost everything here is a two-minute fix.
What you see
Flow keeps showing an “unusual activity” error.
Why
Google has decided the traffic looks automated.
Fix
In order: switch the mode to Agent Automation, create a new Flow project, raise the wait between prompts in Settings, then try a fresh browser profile. The panel has this same checklist behind the “Flow refusing to generate?” button at the bottom of Control.
What you see
You cannot generate by hand either, not just through Erasio.
Why
Your Google account has been flagged on Flow.
Fix
No automation can fix this one. It has to be resolved with Google. Confirm you can submit three prompts by hand before running a batch.
What you see
Run says the tab needs reloading.
Why
The Flow tab was open before Erasio was installed or updated, so the automation is not loaded in it yet.
Fix
Reload that tab and press Run again.
What you see
The Run button is greyed out.
Why
Either there are no prompts in the box, or the Google page it needs is not open.
Fix
Check the prompt counter under the box, and open the Google tab. The panel tells you which one is missing.
What you see
The batch stops after the first file, with a “Save as” window open.
Why
Chrome is set to ask where to put every download.
Fix
Open chrome://settings/downloads and switch off “Ask where to save each file before downloading”.
What you see
The batch stopped on its own, part way through.
Why
Usually the Google tab was closed or navigated away. Sometimes credits ran out.
Fix
Erasio says which it was. Reopen the tab and run the remaining prompts — or top up, then re-run only what is left.
What you see
Every single prompt is failing, and it worked yesterday.
Why
Google reshipped the page and the buttons moved.
Fix
Open Settings, find the compatibility card at the bottom, and press Refresh now. That pulls the current button locations.
What you see
Files are saving, but the watermark is still on them.
Why
Either removal is switched off, or the wrong engine is selected, or the quality is one Erasio cannot intercept.
Fix
Check the watermark chips at the top of Control, try the other engine, and see the quality note in Settings.
The words we use
Prompt
One instruction you would normally type into Google yourself — one description, one question, one idea.
Batch
A whole list of prompts run one after another without you sitting there. That is the entire point of these three tabs.
Credit
What one generation costs. Your Erasio credits are shared — the same balance works on this website and in the extension.
Watermark engine
Which mark Erasio should look for. Sparkle and Veo are two different marks; picking the wrong one leaves it in place.
Queue
The list of prompts waiting their turn, and the window that shows you how far through it is.
Selectors
How Erasio finds the buttons on Google’s page. Google moves them without warning, which is why there is a Refresh button for these.
