Not sure why you think the depth of field is "sudden" because i certainly can't see that, and it is a gradual blur because that is how depth of field is set up.

The crawl actually fades out a few frames earlier than the original. i think you might be thinking of the prequel crawls as the fade out ridiculously early. And you can still see "the empire strikes back" at that point on the original too.

But i'm not trying to recreate the original crawl because there are so many differences in the crawls with each movie. You can just how bad it is here:

This is a new crawl that can be made consistent with all the revisited movies. I don't care if it doesn't match the original perfectly because that is not what i was going for.

I've double checked the original file i uploaded and there is no glitches in it like has been reported and the same file was used for the facebook upload and it doesn't appear there. the only thing i can think of is something got corrupt somewhere down the line. You can clearly see that its a video playback glitch
