Uh, there is a tool called FuckItUp somewhere in this forum which does that stuff with one click.
It uses stormlib, so just taking the source, slapping a current version of stormlib over it and recompiling should fix that.
I was never told that the tool no longer works, thus assumed it did. I would not suggest everyone to download and fix it, but suggest that instead of making a seven minute video, one should just fix it once, which probably is a few minute job.I don't remember putting up any license stuff, so that's probably a leftover from stormlib itself. Nevertheless that clause likely does not apply for distributing a patched version in source and precompiled binary form.Thus, I stand by my first reply: one should not do stuff manually if there is a tool available, even if it requires a few minutes of fixing, seeing that editing a video probably takes longer.
