Run the same steps on many files with Batch

Batch runs the same steps on many things at once: cut out 40 product photos and put them on white, reframe a week of clips to 9:16, or make a picture for every line of a list and then sharpen each one. Open Tools → Batch, or pick several files in your Library and press the Run a batch button in the bar at the foot.

1. What it works on

• Library files: pick up to 200. Pictures, videos and sound files can go in the same batch, as long as every step works on each of them.
• Prompts: one a line, up to 200. Pick what each makes (a picture or a video), the model and the shape, and for a video 5 or 10 seconds. Each prompt is made first, then goes through the steps. You can take every step out and just make the pictures or videos.

Files still being processed can't go in yet. Under the first step, Recent batches lists your earlier ones, so you can open one again.

2. What happens to each

Add up to three steps. Each one works on what the step before made, so a cutout can be sharpened, then reframed. The steps are:

• Remove the background, with None, White or Black behind it
• New scene (say what goes behind)
• Sharper (upscale)
• Reframe (to a new shape)
• Change the clip (say what to change)
• Clean up audio
• Dub (into one language)
• Sound effects
• Smoother
• Product video (a photo that moves)
• Captions, which makes an edit for each file, so it goes last

If a step can't follow the one before (a video tool after a picture, say), the page says so.

3. Run it

The last screen shows what each step costs for the whole batch. Name the folder the results go into, then press Run the batch. The batch needs about that many credits in the workspace to start.

It carries on with the page closed. Each file goes through its steps on its own, a few at a time, and lands in the folder as it's done. You hear once, when the whole batch has finished.

When something doesn't work

Each part is charged as it's made, and anything that doesn't work gives its credits back. A file that fails stops there, and the rest go on. When the batch is done, Try those again runs the ones that didn't finish from the step they were on.

Stop stops what's left: what's finished stays in its folder, and what's still making stops and gives its credits back.

From another app

Apps connected with MCP can run a batch too, and check how it's going.
