NO!
DVD players only support progressive at 24 fps, if the original material was film or shot 24p then yes.

The footage is always PAL DV 25fps.

So, only use progressive when rendering out Slo-Mo clips, is that what you are saying?

I don't quite follow the reasoning behind doing the slo mo progessive, maybe the way that works is to create the new frame at one point in time and then nterlace that, this would probably give a better result for slo mo. This is not the same thing as a progressive DVD, they are true progressive, just sequential frames, the display device has to support that as well.

People are mentioning Supersampling for doing Slo-Mo. I am trying to determine the best possible method for implementing Slo Mo.

I have some clips that I want to slow fown to 50% speed, and I am not that happy with the results so far. It shouldn't be this difficult to do. I am playing around with the Supersampling settings and the field settings, but am still not getting great results.

That explains a problem I had. I made some dvds as progressive and while they worked find on my dvd player, other people said they would not play on theirs. I remade it as interlaced and got no other complaints. I've always wondered about that.

I am a bit confused, does this mean that if you do a slo mo (and convert it to progressive) on your DVD, some players may have problems with this?

Who knows the best way to do proper smooth slo mo?

My DVD set top player has a switch on the back to switch from interlaced to progressive. If the disc is interlaced and you switch it to progressive everything takes on a nice blur effect. I haven't tried to render to progressive as of yet for the reason that most people don't have progressive scan DVD players. This is NTSC.

I think the SonyEPM advice on using progressive for slo-mo was probably incorrect. He can chime in and advise us otherwise.

If your source is interlaced, and you are going to view it on an interlaced PAL or NTSC set, then I don't think going to progressive is the correct thing to do.

Here is a link to previous topics about settings for slo-mo. I think SonyEPM got involved in at least one of these:
