sorry, don't mean to hijack this thread..
but this is just too cool...
i took the full screen se version of ep4, and compared it to the widescreen (sorry i had errors ripping the crawl, couldn't compare them)..
first i did them vertically (also rescaling/resizing them to match up)..
avisynth script - ok, now you can see, that they panned around to different
parts of the frame, which weren't necessarily in the center..
------------------------------------------------------------------------------------------------
# show clips in variables a,b on top of each other like this:
# a
# b
# trimmed past the crawl which didn't work properly
clip1 = Mpeg2Source("M:\data\movie\dvd\star wars ep 4 - se Fullscreen\VTS_02_1.d2v").trim(8945,0)
clip2 = Mpeg2Source("M:\data\movie\dvd\star wars ep 4 - se\VTS_02_1se.d2v").trim(8945,0)
StackVertical (clip1,clip2).ReduceBy2()
ShowFrameNumber(offset=9, text_color=$ff0000)
--------------------------------------------
ok, i didn't correct for aspect ratio...
next..
