It's not versioning like you would find in software development. Google will provide you with details (first link for me): http://www.scriptchick.net/Info/Revisions.html The gist of it is that each version gets distributed to various channels of pre-production and production. Once locked, each page has its number and if the page changes, it stays in (!), but new one is added according to certain rules. In a way it's like a commit history printed out, but isn't. It's weird, but it works. |
Nothing in that article supports the assertion that screenplays have a different concept of versioning than software developers. Screenwriters just have a different preferred format for displaying diffs, a different convention for version numbering (but that's completely irrelevant to a tool like git), and a paper-saving way of handling insertions and removals, when printing out on paper (again, irrelevant to git).
Advice like "If it's only one or two words that are different, consider just whiting out the existing script and writing it in, rather than reinventing the wheel and generating a new color." makes it very clear that this industry hasn't even tried to use technology to make these problems go away.
I wonder how long until this whole system gets replaced by tablets that always automatically show the latest revision, without requiring the use of esoteric paper colors.
