[Chris Babbitt] “So, I’m assuming that the only reason for producing a progressive DVD is if you want the 24p look?
Would you still recommend shooting 60p over 60i if going to an interlaced DVD? “
Two benefits of progressive footage:
1. If 24p, there’s a space savings on a DVD of 20% vs. 29.97i or 30p. Also, at a given average bit rate, bit allocation will be proportionally higher per frame given the fewer number of frames per second.
2. Progressive frames generally encode with better results than interlaced frames in MPEG-2 compression.
However, if you don’t want a progressive look (24p or 30p), stick with 720p60.
Consumer LCD and plasma TVs have built-in hardware deinterlacing, which essentially turns 29.97i into 60p. If you shoot 720p60 and downconvert to a 29.97i DVD, the result on a consumer LCD or plasma TV will retain the “live” look of 60p.
Assuming you’re not using a Teranex hardware converter for downconversion, 720p60 will give better results than 1080i29.97 when downscaling to SD 29.97i because no field scaling/interpolation will be necessary.
