Generating Books | Vellum Help

Generating Books

To create files that you can upload to online vendors, you will generate books: To do so, find the Generate button in Vellum’s toolbar:

Note: Generating books requires a purchase. If you haven’t yet purchased a package for generating books, this button will read Purchase instead.

Press the Generate button to begin the process:

Initial Setup

The first time you press Generate, you’ll be asked to select the platforms where you’ll make your book available. You’ll then select the folder on your computer where Vellum will place your generated books.

By default, Vellum will generate files for individual ebook platforms (such as Kindle, iBooks, and Kobo). If you choose to upload to an aggregator (such as Draft2Digital, Pronoun, or Smashwords), you will want to add Generic EPUB to the list of platforms.

Note: If you choose to output ebooks for Kindle, you’ll be prompted to download and install KindleGen.

If you purchased Vellum Press, you’ll be asked to select the trim size to use for your Print Edition:

Generating

Once you’ve performed the initial setup, you’re ready to generate. Press the Generate button in the sheet and Vellum will create files for each selected platform.

Changing Generate Options

If you wish to change platforms or destination folder, press the button to the right of each setting:

Locating your Books

Once you’ve successfully generated your books, the generate sheet will display a Show Files button.

Press this button to open a Finder window with the platform-specific folders that Vellum has created:

Each folder contains files ready for you to upload to online stores. Before you do that, though, we recommend that you proof your books to ensure everything looks as you expect.

Troubleshooting

Why is Vellum prompting me to select another folder?

When Vellum cannot access the folder that was previously used to save your generated books, it will ask you to select a new output folder:

This can happen if you’ve deleted that original folder, or if you’ve moved your Vellum file from one computer to another.

Press the Select button and then choose a new output folder.

I’m getting a permissions error when I try to generate.

If you receive an error when trying to choose a new folder or generate books, you may be running into an issue with the “sandbox” — the system by which macOS grants Vellum permission to access files.

To address this, first quit Vellum. If you are able to save your files, please do so. Since Vellum will auto-save your files, you should find them open again when you return.

You should be able to generate successfully after restarting Vellum. If not, a full reboot should resolve the issue.
