Reelbatch – Batch Image & Video Generator for Google Flow

Run hundreds of image and video prompts in Google Flow or with your own Gemini/Replicate key. Auto-download, characters, chaining.

Reelbatch turns Google Flow into a batch studio. Paste or import a list of prompts and press Run. Reelbatch submits them one by one, or several at once, and saves every image and video with the file names you choose. It is built for people who generate at volume: video channels, ad studios, storyboard artists, online shops and anyone testing many prompts. Bulk generation in Google Flow • Queue hundreds of prompts: paste them or import a text file or spreadsheet • Use any image or video model your Flow plan includes • Text-to-video, start and end frames, and reference images • Images and videos in one queue: turn any row into a video with one click • Change the model, aspect ratio or length for a single row • See the credit cost of the whole run on the Run button before you press it • Automatic downloads with your own file-name template and folders Your own API keys (optional) Prefer to pay per use? Connect your own Google AI or Replicate key and generate without Flow. You pay the provider directly; there is no markup and no middle server. Animate photos in bulk (Pro) Drop a folder of photos, write one motion prompt and get one video per photo, named after the source file. Consistency and storytelling • Characters: mention @Mia in a prompt and her reference images are attached automatically • Chaining: each clip starts from the last frame of the previous one • Turn a generated still into a video with a motion prompt • Variations: "a {red|blue} car" expands into one prompt per option Safe, unattended runs • A credit budget stops the run before it spends more than you allow • Smart retries, a cooldown when Flow asks you to slow down, and a pause when credits run out • Keeps the computer awake during a run, and a scheduler starts a queue overnight • Stop at any time and continue later with the prompts that did not run And more • AI prompt helper: turn an idea or a script into a list of prompts • Results gallery with search, re-run and ZIP export • A CSV log of every output with its prompt, status and cost • Interface in 8 languages Free and Pro Free: Google Flow, 30 prompts a day, one at a time, automatic downloads. Pro ($9/month or $69 once): no daily limit, parallel runs, your own API keys, photo animation, characters, chaining, the scheduler, the AI helper and ZIP export. A 7-day Pro trial is included and needs no card. FAQ Why does Chrome show "Reelbatch started debugging this browser"? Flow only reacts to real clicks and key presses. Reelbatch uses Chrome's debugger interface on the Flow tab, only while a batch runs, to press Generate for you. The bar disappears when the run ends, and closing it pauses the run. Do I need a paid Flow plan? No. Reelbatch uses the credits of whatever Flow plan you have. Pro unlocks features in Reelbatch, not Flow credits. What if Flow changes its page? Reelbatch reads a small public configuration file, so most layout changes are fixed within hours without a store update. Report problems at https://github.com/adck8888/reelbatch/issues Will it spend my credits by surprise? No. Set a credit budget and Reelbatch stops before it is reached. Each prompt is sent once, and a failure after sending is never retried automatically. Privacy Reelbatch has no server. Your prompts, files and keys stay in your browser. Licence checks go to Lemon Squeezy, and the Flow layout file comes from GitHub.
