I used the NSTC DVD. All of the Director’s cut was completed at SD resolution in NSTC (including introducing weird hard-pulldown issues in the edit process) The Pal DVD is actually an upscale and thus doesn’t look as good and has framerate issues where the NSTC DVD ran at 30fps or broke the pulldown cadence. I thought about using the PAL disc to help get rid of hard subs for the one establishing shot of San Francisco Bay but ,because of these issues, the approach I went with initially worked better anyway. I did use two different PAL discs to source the subtitles for this release.
