AI Video Generator With Dialogue

Quick answer: In SceneMixer, dialogue is spoken in the video itself: each line in the storyboard carries its speaker and a voice, and the model performs it with the picture, mouths moving, in the language you set (any of 15 languages). No separate dubbing pass and no extra charge per line; video is 10 credits a second on the default tier. A line can be changed or redubbed afterwards.

How a line becomes speech

Write the line in the script with the speaker's name. The read assigns it to that character; the storyboard places it in a shot with a delivery note and the character's voice tag; the generation performs it. Write dialogue so it is picked up and dialogue and sound in one generation.

You write	On screen
MARA (quietly): Read it before you say no.	Mara says it, softly, in her voice
THEO (on the phone): I'm outside.	Theo's voice from a phone; he need not be in frame
NARRATOR (voice-over): That was the last winter.	A narrator over the picture

Voices that stay the same

Described in words (default, free): age, weight, pace; performed fresh each shot.
A preset from the library (free to match and to change): used as an audio reference on every line, so the voice holds.
Your own clip (members): one you have the right to use.

Pick character voices and keep a voice the same.

Languages

The dialogue language is set in step 1 and every line is spoken in it, with shot timing computed from that language's speaking rate. The same story can be made again in another language for another market. Choose the dialogue language and native dialogue versus dubbing.

Fixing a line after the video is made

Change the words: redub with lip-sync keeps the picture and changes the line. Change a line.
Change the voice: Change a voice in a finished clip.
A line you never wrote: what to do.
Subtitles: matched to your script's words; burned in or SRT, on accounts that have made a purchase.

Limits

Two people talking over each other and long monologues in one shot are weak spots; split long speeches across shots. Real people's voices cannot be cloned.

Native dialogue in 15 languages

Every series below was produced by the same pipeline with the cast speaking that language natively: the interface, the working documents and the spoken lines are all in one language, and nothing is dubbed. Open one to hear it.

In SceneMixer vs. stitching tools together

Most AI drama workflows are five or six tools in a row. This is where each step happens here, and what it replaces.

Step	In SceneMixer	Doing it by hand with separate tools
Script and episode plan	Paste a script or a novel, or type one line: it is read into a cast, locations, props and an episode outline you can edit	A chat model writes the script; you split it into episodes and carry the text from tool to tool
Character faces and places	Every character, location and prop is drawn once as a reference sheet and attached to every shot it appears in	An image model, one sheet at a time; you upload the right reference to every clip yourself
Shots	A storyboard per episode with numbered shots and seconds; video is generated segment by segment in 9:16 or 16:9 against the same sheets	A video model, one clip per prompt, describing the same people again each time
Voices and dialogue	Lines are performed in the video itself, one voice per character, in any of 15 languages	A text-to-speech tool for each line, then a lip-sync pass on every clip
Fixing one shot	Edit that shot's text and regenerate the segment alone; the rest of the episode is untouched	Regenerate the clip, then re-cut the timeline
Finishing	Segments are composited into one episode file with its score; members download without the AI badge	A video editor to join the clips, add music and captions, then export
Publishing	You upload the finished episode to TikTok, YouTube, Instagram or anywhere else; nothing is posted for you	Upload by hand, the same as here
