Fade In came about largely because complaining about the unfortunate state of the art of screenwriting software (i.e., the industry standard Final Draft) is a popular pastime among working screenwriters. An infamous, perhaps apocryphal observation by one well-known filmmaker was that Final Draft is version 8 of a text editor and they still haven't ironed out all the problems.
Many of us have used Final Draft on and off for years. Many of us have written and rewritten scripts with it. We've had it crash. We've had it behave badly. We've wanted things from it that it couldn't deliver. But it gets used nonetheless, partly because it was first and is the de facto industry standard, and partly because it works, sort of and most of the time.
But, industry standard or not, it's hard to imagine that there's no way to improve on it. And that's what Fade In sets out to do.
1. What makes it different than Final Draft or MMS?
Fade In is written by and for professional filmmakers. It's an entirely new application, with a custom script rendering engine written from scratch and optimized for one purpose only: writing screenplays from start to finish.
It's the nature of software that something that's been around for many years and many versions/incarnations undoubtedly has a lot of glue and tape under the hood of an updated interface to hold things together, and the fact that FD and MMS still exhibit issues that users have complained about for years suggests that the situation isn't likely to change without a fundamental rewrite of those applications. Which is what, in a way, Fade In aspires to be.
It provides all the required features of editing, screenplay management, and revision control. It runs on Windows, Macintosh, and Linux from the same core code base. It works with various formats, including Final Draft. And it is continually being enhanced with additional (and new) functionality.
2. What will it offer that free software (i.e., Celtx) doesn't?
It really isn't meant to "compete" with Celtx. Fade In is aimed at writers who want or need something that performs at a professional level, and the fact is that those writers are using Final Draft or MMS, not Celtx.
3. How much will it cost?
That's not decided yet. But considerably less than FD or MMS.
