For solo creators
Most AI video tools sell you credits. Solo Studio doesn't sell you anything after the download — you bring your own MuAPI key and pay MuAPI directly, at cost.

Starts muted so it can play on its own — press Sound or the speaker for audio. Watch the full video with sound on YouTube.
The difference is continuity: the same face across a dozen shots, the same prop in their hand and the same room around them, the end of one clip becoming the start of the next — and knowing what a render costs before you commit to it.
Build a cast once, then write @marcus walks into frame and get the same person, shot after shot. Each cast member holds four reference angles, a voice clip and a reference clip.
A saved reference can be a person, an object or a location — and the app tells the model which it is. So a prop lands in your character's hand instead of arriving as a second person in the room.
Drop in one photo and it generates the missing views, chosen for what the thing actually is. A person gets a three-quarter, a profile and a close-up. A location gets an establishing view, a reverse angle and a detail.
Grab any frame from a finished clip and drop it straight into the next shot as its opening image. That is how one shot becomes the next without a round trip through an editor.
Feed in footage you already shot and describe what should change. Relight it, restyle it, replace the world around the subject.
Give it an opening and a closing frame and it renders the motion between. Continue a finished clip past where it ends. Put someone else's movement onto a still character.
Score, sound effects, and speech in eighteen voices or a cloned one of your own. Give a face a voice with a portrait and an audio track.
Every render written to disk the moment it finishes, named after the shot rather than a timestamp. AI providers expire their links after about thirty days — this is what means a month of work is still there in October.
per month for Runway or Kling, whether you shoot anything or not — metered in credits that burn on the takes you throw away as readily as the ones you keep.
No plan and no markup. You pay MuAPI directly, per render, and the exact figure sits on the button before you click it. A month of light work is a few dollars. A month where you shoot nothing costs nothing at all.
This app is not code-signed. Both systems warn you the first time. On macOS, right-click the app and choose Open. On Windows you get a full-screen “Windows protected your PC” block with no visible Run button — click More info, then Run anyway. Some antivirus also quarantines unsigned installers, so if the file disappears, that is why. Standard for indie tools sold outside an app store.
You supply the API key. There is no subscription and nothing is marked up, but there is also no free credit included.
Updates are re-downloads from this page, not automatic.
One payment, both platforms, and every render billed to you at cost.
