SeedFlow — Seedance Automation for Dreamina & Claude MCP

Batch video generation in Dreamina: SeedFlow writes Seedance 2.5 prompts, shows credit cost before you start.

SeedFlow is a Chrome extension for Dreamina that automates video generation with the Seedance 2.5 model. You describe the scene in your own language, the extension translates it into a prompt the model understands literally, queues clips, shows the total credit cost before you even start, and downloads finished files with scene numbers. It all runs on your Dreamina subscription: no API keys, no per-second payments. Anyone who's worked seriously with Seedance knows the problem. Thirty seconds per generation is great for the first two videos. After that, it's copy-paste: the same prompt with different wording, waiting, downloading, renaming files. And a failed generation costs just as much as a successful one: thirty seconds at 720P is 1110 credits, and you only find out after they're debited. WHAT THE EXTENSION DOES Writes prompts in the model's language. Seedance 2.5 expects a timeline, not a pretty description: each segment names its end frame, has one camera movement, and each reference explicitly states what to take from it and what to leave untouched. You write “thermos ad, thirty seconds, vertical,” and the extension builds the correct structure itself. Words that break the model (fast, cinematic, epic, seamless) are automatically removed. Calculates cost before starting. Above the start button, you'll see how many credits the batch will cost and how many will remain in your balance. The panel reads Dreamina's indicator directly, so the number is always current, not from a price list. After a run, a log of actual debits for each scene remains — the actual cost per video is calculated. Cheaper than API. Dreamina itself has no programmatic interface. The official BytePlus ModelArk API for the same model costs about 0.2312 dollars per second at 720P and is unavailable in the US, Canada, UK, and Australia. A yearly Dreamina subscription comes out to about 0.097 dollars per second — 2.4 times cheaper, but there's no way to automate it. The extension is that automation on top of your subscription. 50 CINEMATIC TECHNIQUES AT A BUTTON. Camera: dolly zoom with arrival point, crash zoom, semi-orbit, FPV flight, crane up, turntable. Time: stop-time, speed-ramp, empty frame as a cut point. Transitions: whip pan per second, overlap, match-cut by shape, first and last frame, bridge between two clips. Product: product as in photo, light sweep over label, condensation, levitation, scatter and self-assembly. Brand, smart edit, previz, audio, style transfer. The catalog is compiled from twenty-five Seedance director's kits and the official Dreamina guide; each technique notes where to insert it and what risks it carries. REFERENCE ROLES. Seedance 2.5 accepts up to fifty materials per generation: thirty photos, ten videos, ten audio. The upload order is the numbering: the first file becomes @Image 1. The extension assigns each its job — “@Image 1 sets the face, hairstyle, and clothes; do not use the background from it” — and the character stops changing from clip to clip. SOUND BY SEEDANCE RULES. Music in parentheses, in-frame sounds in angle brackets, character dialogue in curly brackets, on-screen text in Japanese brackets. Speech works in eleven languages; Russian is not among them, and the panel knows this: it puts “character is silent” in the prompt and defers the dialogue to a voice actor during assembly. SUMMARY OF 23 RULES. Timeline gaps, camera contradictions, requirement overload, age, brands and celebrities, moderation stop-words — everything is checked before sending, i.e., before credits are debited. If Dreamina still refuses, the extension shows the full reason text. DOWNLOADING. The clip goes into the task folder under the scene number, with metadata alongside: prompt, model, parameters, credits spent. If something didn't download completely, the “retrieve finished clips” button will retrieve them from the project without re-rendering. DREAMINA INTERFACE TRANSLATION. Dreamina has nineteen languages, but no Russian, Arabic, or Hindi. The extension translates menus, buttons, reference modes, and prices itself, using a built-in dictionary: offline, without delay, without keys. Your prompts, clips, and project names remain untouched. THREE WAYS TO WORK 1. STUDIO. Manual mode: an eight-node map — script, prompt, camera, techniques, references, stitching, sound, frames. Next to each, it says what's already set and what's empty. Fill in what's needed, click “Start,” return to the finished batch. 2. ASSISTANT. Chat within the panel using your Anthropic key. You write “I need a thermos ad, thirty seconds, vertical” — the assistant asks two or three questions with buttons, suggests ideas with specific techniques, names the credit price, and starts filming. 3. CLAUDE VIA MCP. Nothing to configure: one button copies the instruction to the clipboard, you paste it into a Claude Code or Claude Desktop chat, and then Claude itself raises a local bridge, connects, and works. Tools dream_status, dream_generate, dream_edit, dream_wait, dream_cancel; Claude sees the queue, credit balance, and license. SECURITY AND DREAMINA ACCOUNT The extension presses the same buttons you do, in your browser: 20–60 second pauses between submissions, by default one generation at a time, retry after 5–15 minutes if the service is overloaded, pause for 30 minutes if there are signs of unusual activity. Dreamina passwords and payment are inaccessible to it. We do not bypass moderation, do not remove watermarks in violation of rules, and do not create multi-accounts. WHO IT'S FOR Those who just discovered Dreamina and want to get a good video on the first try: you write the idea in your language, the extension assembles the prompt, and hints guide you step-by-step for the task — product ad, brand video, story, smart edit. A five-second draft costs 25 credits, so you can test an idea before spending a thousand on the final. Those who make videos in series: advertising, marketplace listings, client content. A queue for dozens of scenes, up to four variations per prompt, stitching into a complete video, smart edit of finished video, and a cost log. PRICE First 24 hours after installation are free, no key and no card. Then a free week by email, then 29 euros per year or 79 euros once and forever. One-click cancellation. REQUIREMENTS Chrome 116 or newer and a Dreamina account with access to Seedance 2.5 (dreamina.capcut.com). For “Assistant” mode, an Anthropic key is needed; for MCP mode, Claude Code or Claude Desktop. Website: https://lingoflow.pro/seedflow Support: https://t.me/GuruAppSheet
