I have a project to be burnt ntsc.
I drop 1080 and 720 footage in to be encoded by dvdsp, the 1080 footage comes out good but the 720 lines look bad
thanks for any help

"Bad," but bad how? Sounds like the DVDSP encoding isn't handling the p60 material just right. A couple things to try might be to export the 720 stuff from FCP timeline "using current settings" and then encode the QT movie in Compressor. As a long-shot, I might just try placing your 720 material on a 1080 timeline and export that. Just some ideas.
I've had a few specific shots in 720p60 that didn't encode well to SD MPEG-2. These were shot from an HVX-200 camera with pans on subject matter with high contrast diagonal edges. Diagonal stainless steel rods were the problem. The edges looked blocky and jagged. Most other shots were just fine.

Hi Oliver,
The 720p is progressive, whereas I assume the 1080 is 1080i which is interlaced.
This will look better on a normal set-up which is interlaced. For progressive to look good, you need a progressive player.

Not sure why people keep saying that you need a progressive player to play progressive DVDs. I bet over 90% of DVDs in everyones homes are progressive (24p in fact) DVD players do a great job of interlacing progressive footage, they have too for hollywood's sake.
The problem can arise if someone tries to try a progressive asset and encode it as an interlaced asset within DVDSP. Nobody should be using DVDSP to encode their video. It should always be done before hand in compressor or another encoding software.
Also without detailed settings there is no telling why Oliver is getting bad results (nor did he say how he was viewing the DVD)

I think the problem was with using DVDsp to encode.
It looked like stripe lines noticeable in peoples hats the rocky ground things with distinct lines
It looked bad on my computer and a progressive dvd player
thanks for the help I am not able to use the Internet much at the moment

The encoding presets in DVDSP can be adjusted in the preferences. They can be set to do exactly the same type of encode as Compressor, but the defaults or your current settings might not be what you need. I set them up to match the 90 Minute Best setting in Compressor.

[Tom Brooks]"The encoding presets in DVDSP can be adjusted in the preferences. They can be set to do exactly the same type of encode as Compressor, "
Maybe same TYPE of encode as Compressor, as it uses the basic Compressor engine, but not the range of options that are in Compressor.
For me, never allow DVDSP to encode m2v.
(BTW Cinemacraft encoder beats compressor for m2v encodes)
