Yes, if you export your CustomShow as an editable PowerPoint, the videos will still work.
Note: PowerPoint offers less options to configure how video plays on the slide and less optimizations when video plays on a slide. Video controls and cropped videos may block other content when played in PowerPoint.
To export your CustomShow presentation as an editable PowerPoint, Follow the steps below:
- Open the presentation in the CustomShow editor.
- Navigate to File > Export
- In the popup, select the ‘PPTX’ tab and click the ‘Editable’ option.
- If you want to export all the slides, click “All”, otherwise specify the slides you wish to export.
- Click ‘Export’
This may take a few moments. You can either keep this window open, and a message to download the file will appear. If you close the window you will receive an email when the PPTX file is ready to download.
