Ginge, the link you referred to actually has a video of the Greedo Scene with subtitles. Unfortunately, the camera is not completely steady so one can't completely tell whether the subtitles were shaking.

Here's a direct link to the video. Harmy could stabilize it if he wanted and see if there is a detectable shake.

Also the 35mm subtitle font looks more like the end credit font than this new font that Harmy is using to emulate the 16mm print. The periods and ellipses look squarish while the letters have a slightly rounded appearance (might also be the soft focus). The opposite seems true for the 16mm subs. Perhaps they had different subtitles made for the 16mm reduction?

That would explain why the 16mm subs seem to have more shake... they were added in optically after the reduction. 16mm only has two perforations per side versus 35mm's 4 perfs. Just thinking out loud...

EDIT: If you look at the subtitle, "It's too late. You should have paid him when you had the chance." Notice where "You" falls over Harrison Ford's body. It doesn't match Harmy's current 2.0 version. The rest of the letters are also out of place. Maybe it's more like the GOUT after all?
