There are a few changes from the version that I used in the video:
Update on 1: I just downloaded the latest stable release (9.4.364.0) of the PDF-XChange Editor from their website: This video Micro Tutorial shows how to OCR the pages of an image-only PDF, thereby creating searchable/copyable text, with excellent, free software called PDF-XChange Editor from Tracker Software Products.
But they are all non-free products, many quite expensive. Some can even do it in batch mode via a command line interface. Many software products can do this, such as ABBYY FineReader, Adobe Acrobat (but not Adobe Reader) and Nuance's OmniPage, PaperPort, and Power PDF.
The solution is to perform OCR on the image-only PDFs to create text. The most common causes of this are document scanning software and faxing software/services that create image-only PDF files rather than PDF searchable image files, the latter having the scanned or faxed images and text created by Optical Character Recognition (OCR). We often encounter PDF files that are pure images, that is, they do not have text characters, but instead contain only raster graphics.
