Click on the Publication menu, then select the Publish option. This will open the Publish Wizard.
Note:
The first time you create a video a warning message will appear to remind you to set and exit point or total time for the video to run. If you do not set an exit point or total time the video export process will continue indefinitely until the available disc space is used up, or the Windows file size limit (4Gb for NTFS drives or 2Gb for FAT32 drives) is reached.
Follow the normal publish process to open the Publish Wizard. We strongly recommend using the Settings button to select video and audio codecs before publishing a video publication.
The publication is now published to a temporary intermediate file. When this initial publish is complete click Next to go to the next stage. At this point the actual video export process will begin. Please wait for the video exporter to start
The video exporter dialog will provide feedback on the progress of the export process.
Note:
If you want to abort the export process click the Abort button or press the Esc key. Terminating the video export requires some time to complete so the process may not abort immediately. When the abort process is complete the Abort button will change to OK.
When the export process is complete click OK to return to the Publish Wizard.
Click Finish to exit the wizard and return to the Opus editor.
