The need to render interlaced?

[Chris Smith]

That’s how I always done it. The only diff is sometimes I roll the cams at 24fps to save film so there’s a 3:2 pulldown. If that’s the case, then make sure when your stuff is compressed to Mpeg2 that the settings are on ‘lower’ or ‘bottom’ first. If set on auto it may pick the wrong order. I got bit once from this.

Ppl would tell me my reel was jumpy on certain spots. I didn’t see it because I played the DVD in a laptop which is always progressive.

But on a real TV, some spots indeed would jerk. I noticed the spots that jerked were shot 24 instead of 30. Which means that because of 3:2 pulldown I had some split frames. I realised the field order was opposite going to DVD. So in whole frames you don’t notice it, but in the split frames, time was backwards.

so that’s a gotcha.
