Thank you all for the information and advice. Exporting a video resulted in a normal output. Your suggestion of updating the display driver prompted me to look at the properties set for Videopad in Windows. In properties, compatibility, settings, there is an option "overide high DPI scaling behaviour. Scaling performed by:". I had the "system (enhanced)" option selected from the dropdown menu when the preview was small (1/4 of normal size). When I switched this option to "Application", the preview displayed the normal larger size. This seems to have resolved the issue. Many thanks again.

Thank you. Restoring the default setting in the view menu did not have an effect. I have attached a screen shot and vpj file. The view shown has not changed since first install just under a week ago. screenshot of small preview problem vpj file example

Total newbie here. I have started editing videos and noticed that the preview image of the video is very small. It takes up just the top left quarter of the preview window. It's making it difficult to see which part of the video I am editing. Any help much appreciated!
