Words, a voice and clean sound

Add captions so the film works with the sound off, put a voice on it, and clean up noise.

Many people watch with the sound off. Words on the film fix that.

Captions in one press

1. Click the clip with someone talking.
2. Press Captions in its tools.
3. Wait. Postfjord listens to the part the page plays and writes every word with its time. To write them again in another language, change Spoken language and press Generate captions.

Captions are big and white, and the word being said turns yellow. They use a little of your AI allowance for each minute of sound, and they are on the paid plans. On Free you see a note with a link to upgrade.

Then check them:

1. Open Edit words and click a word to fix it, or clear it to remove it.
2. Pick a style in the grid under Pick a style. There are 31, from Style 1 to Style 31. Bookmark the ones you like to find them under Saved.
3. Open Settings to pick where they sit (top, middle or bottom), the colors and the size.

On a tall 9:16 film, captions stay clear of the buttons that Reels and TikTok put on top. Hide turns them off and keeps the words. Already have the words? Press Add a captions file and pick an .srt or .vtt file. Save as .srt gives you the captions as a file.

A voice on the film

1. Open Music and press the Voice tab.
2. Write what the voice should say, up to 1,000 letters, about a minute of talk.
3. Pick a voice and press Make voice. It lands where the playhead stands.
4. Press the voice in the list to change where it starts and how loud it is.

Show the words on the film turns the same words into captions at no extra cost. Check them in the Captions panel, because a word can come a little early or late. A voice is on the paid plans and uses a small part of your AI allowance. It is made by AI, so add a line to your post, like "Voice made with AI".

Next to Voice is Sound FX: tap a sound to hear it, and press the plus to put it where the playhead is. Each sound gets a small block on its own row under the music.

Short lines sound best. For Bean There: "Fresh coffee, from seven. Come by."

Clean up sound

Pick the clip, open the Sound card and turn on Clean up sound. Street noise and hum go down, and the volume stays even. You hear it at once, and the saved video has the same sound. It is on every plan.

Do it

1. Add captions to a clip with speech, or make a short voice.
2. Fix any word that is wrong.
3. Turn on Clean up sound if the clip is noisy.
