What version of Videopad is being used?
What's the original image size? You want to drop it to 273x183 - is that correct?
Let's take a look. Upload the file/s to a free server, such as Google Drive or MS OneDrive, get a shared (public) link, copy the link and paste it here or to me in a Private Message via the mail envelope in the top-right corner of this forum. When using Google Drive, if necessary change "restricted" to "anyone with link can view."
