Nope, it's the NTSC version. It was probably an importation problem, because I just quickly pulled it into an existing project. I'm getting a duplicated frame at random points in the video, so ignore my previous post.

I found something else which is strange. Mike talked about how the last two frames of the '81 version would have been "lopped off", and so I checked the '97 version against the Team Blu GOUT, and the final frame of the composited Star Destroyer is gone in the '97 version, however the laser blasts are still composited to be in the same place, meaning that the entire Star Destroyer is shifted back one frame in the '97 version compared to the original.

Download both images and flick between them. The Star Destroyer is at precisely the same angle in both, yet this is the second to last frame of the GOUT shot, and the last frame of the '97 shot.
