The most customizable video automation there is.
Free plan, no card required · New accounts: 3 free trial renders (card check, never charged)
This is the real workflow: click a scene, swap it, re-roll it.
Record the narration yourself, in one take or scene by scene with the built-in recorder, and the render carries your voice word for word, with every scene timed to how you actually read it. Prefer synthesis? Plug in your own ElevenLabs voice instead.
Music works the same way: upload your own tracks, pin the one a video should use, or let each render pick from your pool.
A voice viewers recognize is the difference between a channel and a content farm.
Every render opens as a scene-by-scene cut you can actually work. Nothing ships because the machine said it was done. It ships because you did.
Don’t like a shot? Drop your own clip on it. Swap any scene, as many times as you want: footage swaps never cost a credit.
Want a different take from the AI? A re-roll costs one clip’s credits (the exact charge is shown before you confirm), and the rest of your cut doesn’t move. Footage swaps are always free.
A filmstrip of every scene with per-scene previews, so you spot the weak shot in seconds and fix only that.
Generate clips in any tool you like, pull footage off your phone, use anything you have the rights to, then import it straight into your library and drop it onto a scene in the editor. All the common video formats work.
Imports land in your personal library and are never placed without you: you choose exactly which scene they replace, and the swap is free every time. Want footage placed automatically? That’s the smart backgrounds library, below.
Two libraries make a render feel hand-made instead of generated.
Real footage you upload, matched to a story’s beats by what your titles say. Name a clip “crowded 1920s trading floor” and it gets found when the script gets there.
Photos, scans, maps, and documents pinned to a story and woven in as slow-pan shots at their strongest narrative moment.
Placement is deliberately selective: the planner reads the script and places your material only where it genuinely fits, hard-capped at one placed scene in four and often fewer. You set the appetite per channel, from rare accents up to the cap. Anything without a match stays original AI footage.
Viewers can tell. Generic voices, stock loops, and untouched machine output read as slop in seconds. Synthvids is built for the other side of that line.
Whether a video earns its audience is the platform’s call and the viewer’s. What stays in your hands is the quality that goes in, and that’s the part Synthvids is built around.
You direct; the pipeline does the labor. Point a channel at a source and Synthvids finds the story, writes the script, voices it, renders original scenes, and mixes the cut, then hands it to you in the editor instead of shipping it behind your back.
Upload a video you own (a podcast episode, a livestream, an interview) and Clip Studio finds its strongest moments, checks each one, and cuts them into clips. Turn any clip into a captioned short, a combined video, or an AI story. Included with Hobby and up.
A new channel works out of the box with sensible defaults. Every layer underneath opens up the moment you want a say in it, and only then.
Pick a script style for the channel or for a single video, describe the hook tone you want in your own words, or paste a finished script and have it spoken word-for-word.
Start from a built-in visual style, or design your own: medium, palette, lighting, and mood, saved as a preset and applied to every scene the channel renders.
Story sources are a checklist, not a fixed feed: choose where the scraper looks, and type an editorial filter in plain words to say what’s worth keeping.
Every one of those layers has a working default. A brand-new channel can find a story, write the script, and render the video before you’ve opened a single setting.
Synthvids is a Google-certified YouTube developer, and now publishes to TikTok too. Connect your channels and publish with one click, or lay out a full month of renders on a scheduling calendar and let them go out on their own. On TikTok, each video lands in your TikTok inbox, ready for you to add a caption and post it from the app.
Synthvids asks for Google access in exactly two optional places, and uses it for exactly what each is for.
If you choose Google sign-in, we receive your email address, name, and profile picture, used only to create and authenticate your Synthvids account. Email + password sign-up works without it.
When your cut is ready, you can connect your own YouTube channel and publish it right away, or on a schedule you set. We request YouTube upload access to upload the videos and thumbnails you approve, and channel-list access to show your channels (including Brand Accounts) so you pick where to publish and we can confirm the upload went through. Nothing is ever published without your explicit action.
What we never do with Google user data: we never read, modify, or delete your existing videos, comments, subscribers, or analytics; we never use it to train AI models; and we never sell it or share it with advertisers. Connection tokens are encrypted at rest, disconnecting a channel revokes our access with Google, and deleting your account does the same. The full detail is in our Privacy Policy.
A short video uses about 10 clips on average; the exact number follows its length, so it is never a fixed ratio. Every render quotes its cost up front as a ceiling, and anything it doesn’t use comes straight back to your balance. Your first two scene retakes on every render are free. After that a retake costs one clip, always shown before you confirm. Footage swaps are free and unlimited on every plan.
Turn on auto-short when generating a longform video, and it automatically cuts a short from that same render: free, on every longform render, on every paid plan.
Try the research tools free, no card. New accounts can also try 3 free renders.
Your first automated channel: on average about 6 short videos a month.
For creators ready to publish consistently with AI.
For daily publishers who need volume and control.
For serious creators and small agencies.
For agencies and high-volume publishers.
Plan credits are added monthly, and unused credits stay on your balance while your plan is active; top-up credits never expire. The Free plan carries the research tools (story scraper, script generator, metadata) with no card. For a limited time new accounts can also render 3 free short videos (watermarked): verify a card to start the trial, and it is never charged or saved. Beyond the trial, rendering takes a paid plan. Credit top-ups are an add-on for an active plan, not a way in.
Start free with the story scraper and script generator: no card, no setup. When you find the story worth shooting, render your first three shorts free in the trial (a card check, never charged), then from $12.99/month (6,000 credits, about six short videos), and take your first pass in the editor.
