Constrain to Fixed Size

You may have realized by now that most video files are not small. Movies are huge chunks of data compared to almost everything else on your computer. In fact, this user guide is about a thousand times smaller than your typical film.

Storing lots of DivX files may be a challenge for you, so Dr. DivX provides the file size constraint to help you out. Just tell the doctor the maximum size you can tolerate and Dr. DivX will choose the right mix of settings to get the best quality video possible without exceeding your size limit. This is particularly handy if you are trying to squeeze a movie on to a 128 Meg memory card or if you'd like to burn a two hour film onto a 700 Meg CD.

Someday, Dr. DivX will allow you to split your videos into multiple files. You see, some folks would like to store long movies on CDs but they find the quality is a tad disappointing if the entire film is limited to 700 Meg. Output file splitting is just what they need. For example, most feature length movies can be divided into 2 files of less than 700 Meg which can then be burned onto two CDs. Unfortunately, this feature is not currently implemented in Dr. DivX so the file count is always 1 and you can't change it.
