If you took the crawl from the '97 version then isn’t that the '97 Crawl (where the Star Wars Logo races quickly away instead of slowly as it did in '77 and '81)?
I recently restored the actual '81 Crawl from an Eastman 35mm Print for use in v1.5 (This is the same one that was distributed with the SSE, but which at that time still had almost no stars. The Fox Logo, Long Time Ago, Pan Down and Flyover are all SSE, but the Star Wars logo and complete Crawl are taken directly from the Eastman print, stabilized and placed on top of the SSE star field…
If you need a version with less compression let me know.
That composition is quite nice, and the 1981 text is in great shape, and stable now. But as DL says, the issue is the starfield presumably. I wonder if you can grab the starfield from your own ESB scans somehow, if not from the actual 1981 intro.
Interestingly, I think the version you’ve created is most similar to the 1997 edition (1981 crawl text and speed with 1977 starfield). 😃
