AI Video Generator Software: Cloud or Local, and Where Your Files Go
Try it: open Assets, pick a finished clip and press Download, then play the file from your own disk. That is the full-quality copy; the one the site plays in the page is a lighter one, and the gap between the two is the first thing to know about cloud video.
Three places AI video software can live
| Kind | Where the model runs | You provide | Where your material goes |
|---|---|---|---|
| Runs on your own computer | On your own graphics card | The hardware, the setup, the model files and the updates | Nowhere, unless you upload it |
| An app you install that calls a cloud model | On a remote server | The install and its updates, plus a connection | Sent to the service for each generation |
| A website you open in a browser | On remote servers | A browser and a connection | Uploaded to, and stored by, the service |
None of these is better in general. Software on your own machine trades money and setup time for control of the files. A website trades control for having nothing to set up and for using models that no single computer could run. SceneMixer is the third row, so the useful questions are the ones below: what runs in your browser, what is stored, and how you leave.
What runs where in SceneMixer
In your browser: pasting text; unpacking a Word file to plain text before anything is sent; converting a picture to JPEG before it goes up; sending an upload straight to storage; playing a lighter copy of a clip; downloading the full-quality file.
On servers: reading the script into a cast and an episode list; making the setup pictures; writing the storyboard; generating every video segment on a model service; adding the AI badge; and joining segments into an episode. Because of that split a phone can do everything a desktop can, and closing the laptop does not stop a generation. What runs underneath.
What your computer needs
| Need | What it takes |
|---|---|
| Graphics card | None. Nothing is rendered on your machine |
| Install | None. A web browser on a computer or a phone |
| Connection | Enough to upload what you choose to upload, and to download finished files. A generation itself does not need you connected |
| Disk space | Only for the files you download. The full-quality download is a separate, larger file than the lighter copy the player streams |
| Image formats | Whatever your browser can decode: WebP, HEIC, PNG or JPEG. SVG, camera RAW and HEIC outside Safari are refused when you pick them |
| Script formats | Pasted text, or TXT, DOCX and Markdown. PDFs are refused: export to text or Word first |
Where your files live
Uploads go straight to storage. Your browser asks for a short-lived permission, good for fifteen minutes and for one address only, then sends the file directly to object storage. It never passes through the application servers, and when the upload finishes the site checks the bytes that actually arrived rather than trusting what the browser said it was sending.
An address is unguessable, not private. Every picture and clip is shown through a long signed address with an expiry. The addresses are not published or listed, but whoever holds a copied one can open the file while it is valid. To show someone a finished clip, use Share, which makes a proper page; a shared copy always carries the badge.
References can travel. To generate from a reference, the site publishes a copy of it where the model service can read it, and that copy may sit in storage in the region the service runs in, not necessarily where your account’s data is. If material must not leave a particular jurisdiction, weigh that before uploading it.
Only uploads count against your storage. Every generated picture, take and episode is stored at the site’s expense. The quota is reserved when an upload is authorised and given back when you delete.
Deleting is final. A deleted asset, episode or project disappears from your account at once and its files are cleaned up afterwards, after a check that nothing else still uses them. There is no restore on the site. Where your files live has the full account.
Getting your work out
- Video. Every segment and every joined episode has a Download button that gives the full-quality file. A free account’s files carry the small AI badge; on a paid plan it is off by default.
- Pictures. Characters, scenes and items can be downloaded from the Assets page, across all your projects.
- Text. Your script is yours already. Storyboard text can be copied out and pasted back in; check the links after you paste.
- A project as a whole. A project cannot be moved to another account. Hand over the script, the character pictures and the downloaded videos instead.
What you get to keep covers the terms: output is yours to use, commercial use included, to the extent the law allows. It is not exclusive, and keeping your own copy of anything important is sensible given that deleting here is one-way.
Make it in SceneMixer, start to finish
- Script: paste your own on Upload Script, or write a one-line brief in AI Create and let it draft the episodes.
- Step 1: Type Film; Scene Style Nordic Minimal; Costume Style Outdoor Gear; Visual Style Painterly Anime; Target Region; dialogue language; 16:9 Landscape. Then read the script.
- Step 2: the keeper and the stranger as characters, the lighthouse and the shore as locations; the lantern as a prop. The first 15 setup images on an account are free.
- Storyboard: generate episode 1 first (free on your first drama) and read it before you render anything. One place per segment.
- Video: render on the default tier at 10 credits a second, fix single shots instead of whole episodes, then put the episode together and post.
| Question to ask any AI video software | Why it matters | SceneMixer |
|---|---|---|
| Where does the model run? | Decides what hardware you need | On servers; nothing to install, no graphics card |
| What leaves my computer? | Decides what you are comfortable uploading | Only what you choose to upload, plus the text you paste |
| Who can open a file? | Preview addresses are often mistaken for private | Unguessable addresses with an expiry; share page for showing others |
| What counts against storage? | Quotas can be spent on your own output | Only your uploads; generated files never do |
| Can I leave while it works? | Decides whether you must stay connected | Yes; generations continue on the server |
| How do I get the file out? | The exit matters more than the entrance | Full-quality download per segment and episode; no project export between accounts |
FAQ
Is AI video generator software cloud or local?
Both exist. Local software runs the model on your own graphics card; cloud software runs it on servers. SceneMixer is cloud: you use it in a browser and the models run elsewhere.
Do I need a powerful computer?
Not for SceneMixer. Nothing is rendered on your machine, so a phone or a modest laptop is enough.
Do I need to download or install software?
No. You open it in a web browser. You only download the videos and pictures you want to keep.
Can I use it offline?
No. It needs a connection to upload, to sign in and to download. A generation, once started, continues on the server even if you disconnect.
Where are my files stored?
In object storage, reached by long, unguessable addresses. Uploads go straight from your browser to storage. Only what you upload counts against your quota.
Is a preview link private?
It is unguessable rather than private: anyone holding the address can open the file until it expires. Use Share to show a clip to other people.
Can I move a project to another account?
No. Hand over the script, the character pictures and the downloaded videos.
What happens to my files if I delete a project?
They vanish from your account at once and are cleaned up afterwards once nothing else uses them. There is no restore.
Nothing to install: open it and paste a page
Your browser does the pasting; the servers do the rest.
