Should I render in progressive scan for video going to HDTV?
Hi guys,
Sorry to repost the same issue, I know everyone’s had a chance to respond, but I still need some help on this. I’m rendering a DVD that will be sold and noticed an issue on a shorter version of it that I played on an HDTV. It’s 1920×1080 video shot at 24 fps progressive scan, and I rendered it how DVDs normally are, to mpeg for video in 720×480 interlaced and audio as a separate ac3 file. It played fine on my CRT tv, but when I had a chance to play it on an HDTV with what I believe was an HDDVD player, it was obviously doing some kind of interpolating of the interlaced fields because the video looked unnaturally smooth and almost like slow motion at times, though it was still playing in real time. It looked like it was being made to play in 30 fps.
All I can figure is that I should render the DVD in progressive scan, but I don’t know if this will create an issue for standard DVD players and CRT tv’s. Any ideas?

HD-DVD was officially discontinued on February 19, 2008. Today all DVD Players are Standard Definition. Only Blu-Ray Players play HD content on Blu-ray discs.
As it is implemented, DVD is not a high-definition format. DVD players typically output video in either standard NTSC 480i (720×480 pixels in an interlaced scan format), with progressive scan DVD players capable of outputting DVD video in 480p (720×480 pixels displayed in a progressively scanned format).

Hmm. It must have been an old DVD player.
Regardless, should I change my render setting to progressive scan?

Since your source material is 24p, the short answer is yes, in 24p.
The long answer is the proper settings to use and, since I don’t shoot 24p HD, I don’t feel qualified to give you an answer.
I’m positive this topic has been addressed here in the past so I suggest doing a search for some tips. -

It’s only 1/6.
720 x 480 = 345,600
1920 x 1080 = 2,073,600 -
Thanks, guys. I’ll try it progressive scan. I never did before since I thought most DVDs were interlaced, and if they were playing on a progressive scan tv that the DVD player could play it back progressive scan, but that interlaced was preferred.
