1. Click output to go to the output window.
2. Click format and then click settings.
3. Reduce the values of resolution, bit rate, frame etc.
4. Then the exported video will be with a smaller size.
As you know, a standard DVD has 4.7G space,so if your project is bigger than 4.7G, it will prompt you this warning.
To fix it, you can try the following two methods:
1. Change the video quality option to low quality so that the software can help you compress your video to a smaller size.
2. Try to insert a new dual layer DVD which has 8.5 G space.
