Just FYI, that guy seems to have an old leaked tool-assist build of WA. Here is a thread written by me in 2007 which contains a full explanation of the tool-assist builds' capabilities:
http://tasvideos.org/forum/viewtopic.php?t=5736The TAS builds are generally not public, though there was a leak by someone who no longer has access to new builds many years ago. The TAS builds do not have network (read: internet) gameplay capabilities. The replays they produce are encrypted, and therefore can not be played back by public builds of WA. There is no way to disable trajectory mapping within the TAS builds, so that's why you see it in that video. Also, that guy sucks at tool-assisted roping.
