Four things people mean, and what happens to each

If the song must drive the picture, you need a tool that reads audio. If the picture must tell a story, read on. What you can feed in.

What SceneMixer does with sound

Four kinds of sound exist here, and none of them is a song you supply.

• The built-in score. Once an episode’s first shot is generated, the site plans music from the storyboard (which mood each stretch needs, where it turns), picks a piece for each stretch and mixes it under the voices. There is no track picker, no volume control and no request box. A Music switch beside the player turns it off, and a download with it off is the dialogue version without music. How the score works.
• Spoken lines. Each character has a voice, in any of 15 languages, and a shot with no dialogue has no voice at all; what you hear is the ambience written into that shot. Dialogue and sound in one generation.
• A character’s voice sample. Members can upload a short clip as the reference for how a character speaks. It is a speaking-voice reference, not a track to lay under pictures. How character voices work.
• The sound of a video you upload. In a remake, the clip’s speech is transcribed and the music is described, and that description sets the tone of the new episode’s own score. The source track itself is never used. How a remake reads dialogue and music.

A narrative music video in six steps

1. Mark the song. Write down where the verses, choruses and bridge start, in seconds. That list is your structure.
2. Write the story the song tells. One place and one beat per segment. Give the lyrics as the idea; do not paste them as spoken lines, because spoken lines are voiced.
3. Pick the type. A Short Drama episode runs up to 240 seconds, a TV Series episode up to 300, and a Film has no cap, so most songs fit one episode.
4. Choose the segment length. Step 3 has a segment-length switch: 15 seconds as standard, or up to 30 for a long take on the tiers that allow it. A 30-second verse is two short segments or one long one.
5. Write silent shots. Leave out dialogue, add an Ambient: line, and read the storyboard before you render. Editing text is free.
6. Render, download with Music off, finish in an editor. Put the song under the picture, trim each segment’s start or end to land on the beats, and add timed lyrics there. Trimming a clip.

From song sections to segments

The typical lengths are ordinary song structure, not a product rule. The only fixed numbers are the segment sizes and the episode caps above. Shot seconds and timing.

A lyric turned into shots

Take an invented chorus line: “The porch light stays on for the one who left.” As a story beat it becomes images, not a sung line. Three shots, twelve seconds, no spoken words:

The same porch comes back each time the chorus does, which is how a repeated lyric becomes a repeated image. The shot format · A stage-and-studio story.

Length and cost

Video is charged per finished second: 10 credits a second on the default tier (about $0.06 a second at the lowest credit price), plus 1 credit a second to join. A three-minute video is 180 of those seconds. New accounts start with 50 credits, the first 15 setup images are free, the first storyboard on your first drama is free and a 5-second preview is free, so you can draw the cast and read the whole storyboard before spending on video. Where credits go in one episode.

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.
