Hi Selva, You've got me worried now! Just when I thought I had a handle on this process...
No, my source material is not exactly 24, it's from an ntsc DVD and it's 23.9 something - i thought that the target rate to shoot for was 29.9 something as well! Aren't these fairly common values? If I need to, how can I skip every thousandth frame or so as you suggested??
