I have just put together a DVD for a wedding video, but the videos that I exported (one is full HD, the other standard def - both MPEG2) are not de-interlaced. I burnt the standard def DVD and played it on my HD TV... you can tell clearly it needs to be de-interlaced.
I'm wondering, to save myself another two 11 hour render times, if the clips can be de-interlaced in Encore while burning?
You can't de-interlace the video while burning. Encore will only burn the DVD compliant video, it won't de-interlace unless you give it a new encoding preset in which it will de-interlace (which will also re-encode the whole thing. As I'm sure you are already aware, de-interlacing a video reduces the resolution....actually cuts it in half. Be sure you REALLY want that before encoding again. Those who watch on an old CRT TV will not notice the interlacing, in fact the interlacing will make it look smoother (unless the field rendering is backwards).
