When I am editing a video the view inside video pad looks fine but when i export and play video it looks like the screen is decreasing in size. so the words from text getting cut off.

What version of Videopad is being used?

This is likely a composition error.  Try setting the preview screen to... 

Then view the Sequence when composing.

Above the preview windows, click on the Sequence tab, if necessary, or enable the Dual Preview mode...

Be sure that text is within the active video area.

If that doesn't solve the problem, take a few minutes to share the project for analysis...

The process is easy, quick and can be done privately.  Just follow these steps...

•     Back up --- With your project on the timeline, click on MENU at the top-left.  Click FILE|BACK UP PROJECT FILES TO FOLDER.  Choose a folder and SELECT FOLDER.
•     Upload ---  Use a free server - Google Drive, MS OneDrive, etc.* - to upload the saved, numbered FOLDER.    Do NOT upload the individual VPJ or export file. 
•     Get link --- Get a public link.  Right-click the file and click SHARE. When using Google Drive, if necessary change "restricted" to "anyone with the link can view" 
•     Share ---     Click COPY LINK | DONE.  Paste that link here, or click the folder at the top-right of this forum to message it privately to me.  It won't be shared.

          *    Before uploading, right-click the folder, click PROPERTIES.  Look at the File Size to confirm that it's not too big for the free space on the server.

Export at 1920x1080.  If you want to get fancy, apply the Blur Pad to Aspect Ratio effect upon export...
