Project properties
Author: ffDiaporama Team

This dialog allows you to define the information which qualifies the project.
This information will then be registered in the form of TAGs in the rendered video files.

#### Remarks:

- The properties of the project are a partial implementation of the MPEG-7 standard on the descriptors of multimedia contents.
- These properties are written into the video files during the rendering and can be exploited by indexing systems (collection managers) or by Media Center Systems.

## Settable fields

Fields | Remark
Project geometry | This field allows you to select the geometry to be used for the project. Remark: This field is only editable when the dialog box is used for creating a new project. Subsequently, it is not possible to change this value.
Title | The title of the project Remark: If the id3v2 compatibility option is set in option dialog, this fields is limited to 30 characters

Album | The album of the project Remark: If the id3v2 compatibility option is set in option dialog, this fields is limited to 30 characters
Language | The language of the audio track (ISO 639 standard - 3 characters)
Thumbnail | These options allow you to define the thumbnail that will be attached to the video file when rendering
| Create a new model from this thumbnail or edit custom thumbnail. Opens the Edit thumbnail dialog.
| Customize the thumbnail only for this project (without creating a new thumbnail model). Opens the Edit thumbnail dialog.
| Expor thumbnail to a jpeg file. By default, the proposed file name is "folder.jpg". ffDiaporama and many Media Center Systems recognize this file as the icon to be used for the directory that contains it.
Event date | The date of the event of the project
Override date | Check this box to override the date and offer you to enter the date as a free multi-line text

#### Remarks:

- Some fields are automatically filled and do not appear in this dialog:

  Timestamp | Date and time of generation of the video.
  Composer | Contains the version of ffDiaporama with which the video was produced.
  Encoder | Contains the version of libavformat (ffmpeg) with which the video was produced.

- For more compatibility with indexing systems and Media Center Systems, ffDiaporama does not include the whole video TAGs but is closer rather to the standard id3v2 than is the most used by these systems today. Furthermore, the video formats do not support every TAG in the same way.
