Sound

Give your film voices, sound effects and a clean mix. Five steps, in this order.

Plan Sound free

It takes your clips and your script, and it does three things:

• Gives every speaking character a voice. Two characters in a scene never get the same one. Each one also gets a short description of how the voice should sound.
• Fits every line to its clip. If a line is too long for the shot, it tells you. Make the shot longer instead of making the line faster.
• Reads the mood of each scene, which the sound effects step then uses.

This step is free.

Design Voices by the minute

Optional, and it is what makes your cast sound like a real cast.

Open a character on the Sound board. There is a line about their voice already. Rewrite it in your own words: “a low, tired man, about forty-five, dry and a little rough”. Say the age, the speed, the mood and the feel of the voice. Do not use the name of a real person.

Run the step. Each character says one test line in their new voice, and that recording is kept as their voice sample.

Why this matters: from now on every line that character says is made from that one sample. So a line you make again next week still sounds like the same person. Do not like a voice? Run the step again.

Or bring your own voice. On the same character, upload 3 to 10 seconds of clear speech. It goes in the same place, and no design is needed. If you know what the person says in the sample, type it in too — the result is better. You must have the right to use any voice you upload. See the Terms.

Generate Voice-over by the minute

Reads your script out loud in your cast's voices — one sound file for each line — at the speed Plan Sound worked out for each shot.

Because one line is one file, one bad reading is one small fix: open that line and say it again, in the same voice, at the same time.

There are nine ready-made voices, and you can design or upload as many as you like. Ten languages are supported: English, Chinese, Japanese, Korean, German, French, Russian, Portuguese, Spanish and Italian. Every voice can speak all of them.

Generate SFX by the minute

Watches each clip and makes background sound and effects that match what happens in it — one sound track for each clip. It uses the mood Plan Sound wrote for the scene.

A film with talking and no background sound feels unfinished. This is the step that fixes that.

Clean Sound by the minute

Run this last, over all your sound at once. It takes out hiss and noise and makes the levels match, so the voices and the effects sit together.

Where is the mix?

In Deliver, next to the render. The mix is made fresh every time, so it always uses your newest clips and voices.
