DSE:

I just ordered your book. These posts really got me wanting to learn more.

I don't see 'Interpolate' and 'Deinterlace' in Vegas 5?

How is this accomplished in 5?

File>Project Properties Deinterlace Mode.

I'm coming in late on this thread.

I agree that DVFilm Maker results in serious aliasing on high-contrast, diagonal edges, as well as washing out of highlights. I spoke briefly with DVFilm owner, Marcus van Bavel, at 2004 SXSW and asked about that issue. He made the valid point that Maker has a variety of variable settings to adjust the sharpness (hence aliasing) versus softness. Vegas only provides a fixed setting.

From my own perspective, Vegas "interpolate" de-interlacing results in a softer image. I posted a procedure and some samples of Vegas de-interlacing that can result in recovering that lost detail. That's on this thread:
