We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
Sound Editing
A difficulty with magnetic stripe is that of fitting sound accurately to a sequence including rapid cutting. You may then have to record a different sound every second. It is out of the question to record all the sound at one attempt. Instead, you must run the film through the projector several times, recording different passages each time. There are two ways in which you can tackle this.
1 . By recording one or more passages, reversing, checking, and then recording other passages.
2. By making an endless loop which can run repeatedly through the projector until you have recorded all the sound correctly.
Both these methods produce excellent results when used properly. However, there are several points to watch if you want to work quickly.
If you intend recording, going back, checking and then recording a further passage, you need a projector which can run in reverse. Some, but not all, magnetic stripe projectors have this facility. Those that do not, must be unthreaded and re-threaded every time you want to go back, and this is a tedious business.
When you record sound for one shot, you may have to be careful not only where you start it, but also where you stop. On some projectors the erase head is a considerable distance ahead of the record/playback head. This means that when you switch from "playback" to "record-erase", over a foot of film between the two heads will not be erased although you would like it to be. So if you let the sound for one shot overrun a little, it will not be erased automatically when you record for the next shot.
On the other hand, some projectors are constructed so that the erase head is very close to the recording head. Then it is actually desirable to let each recording overrun. When you add the next passage of sound, you erase the end of the preceding passage and the two fit without gap or overlap.
