The following output format settings are available for all file types.
| Property | Description |
|---|---|
| sourceOutputFormats |
The output format to use as a source for rendering. This allows you to render small thumbnails from formats other than the original to save time and rendering power. See Rendering Chain for details. |
| format | This is information about the technical format for the output, e.g., JPEG, AAC, or video still. |
| names | The language-specific names that Fotoware Alto displays in the format selection dialog. |
| retentionTime | A setting used for dynamic formats that defines how long the dynamic outputs created from this format are kept. |
| downloadFileNamePatterns | The optional patterns (liquid syntax) that produce the filename for an item of this output format. If set, the customer's default language must be specified. |
| viewForAll | This permission indicates if outputs derived from the original output format should also be accessible to users without AccessOriginal permission on the content. Without this permission, output formats derived from the Original will require access to the Original. |
| enableXmpWriteback |
This will allow us to write metadata values from Fotoware Alto into the XMP header of outputs where applicable and configured. To enable writeback for the original, you have to use copyFormat to create a copy of the original and then writeback to this copy. |
| id | Output format ID, which must be unique among output formats. Supported are alphanumeric, uppercase, lowercase, and dashes. It is recommended to use a name similar to the original, but without a leading number. For creation, ID must be set; for update, it cannot be changed. |
| system | Marks if this is a system output format, which is required for Fotoware Alto, e.g., thumbnails. This is a read-only property. |
| dynamic | A dynamic output format is not rendered automatically; it is available only on demand and only in a single download. Dynamic formats are not backed up. |
| dataExtraction | Specifies the output format used to create transfer thumbnails for non-imported items in the Frontend or via the items. This is a read-only property. |
| temporary | Temporary outputs will not be backed up and are mainly used in the Rendering chain. See Rendering Chain for details. Temporary formats are not available for download in the Frontend or via the API. |
