SOME STREAMLINING BASICS:
1.Easy Does It: Do not start by selecting ALL Streamline preferences -- you'll get too many suggestions. Start with the defaults first, then, if you're not getting enough suggestions, add more tests.
2.Rescan after making changes. Try making a few suggested changes and then re-scan. Rescanning may give you better, more relevant changes once you've made suggested modifications.
3.Every script is different. The effectiveness of Streamline is highly dependent on writing style and document length. Some scripts can easily lose a few pages with a little work, while others may feel like pulling teeth. If you write brief, terse dialog and action, Streamline may not be able to locate many edits that will decrease your page count. In this case, you should try some of the more aggressive tests, like "Delete 1 trailing line" to discover if there are any multi-word lines which can be reduced.
4.Don't take the suggestions literally! Streamline accurately locates critical words or passages that affect pagination, but if it says "delete this word and you'll save a page", be aware that pressing the DELETE WORD button WILL delete the suggested word -- but it's up to you to restructure the sentence (to be shorter) to make sense. Similarly, deleting an entire paragraph should only be enacted if it actually makes sense to do so. Often, Streamline will identify an AREA which contains a critical passage which, if shortened, will save you page count -- but you'll probably want to close the Streamline window and hand edit the area indicated by Streamline.
5.The point of no more loss: It's possible that by intensively Streamlining, the script can reach a point where no other changes can be easily detected. That's good, but if you need to reduce page count more, you'll probably need to cut whole paragraphs -- or more.
6.If you're on a slow machine, you may find it more convenient to use the popup (to the left of the Scan button) to Streamline a PORTION of your script -- a page or a scene, for example.
