converting 30 fps progressive to 25 fps (interlaced or progressive)
I’m looking for a way to convert NTSC (30fps progressive) material to PAL (25 fps, progressive or interlaced doesn’t matter)
The orginal material is from a dvd ripped with DVDxDV PRO, and my mission is to convert this to something playable on my TV station, which uses PAL, and they take material in either interlaced or progressive format.
I’we tried various methoods to convert my material to 25 fps and the results aren’t that good. Here is what I’we tried:
Program: Compressor, using frame blending
Results: The frame blending effect is very noticable, and movement is not smooth, but the clip plays at the right speed.Program: Nattress Standards Conversion
Results: I used the G Film Converter seto to “60p to 24p and the video was just speeded up.Program: Shake – “retiming” in “filein” set to “convert
Results: Same as with Nattress, the video was just speeded up.Now I’m thinking, since it’s possible to convert 24p to 30i using 3:2 pulldown, it must be possible to do the opposite. Is there some program out there that might be able to do this? I actually suspect that Nattress Standards Conversion is able to do this, but I just haven’t figured out how.

I did just that, and it worked wonders. I guess I was making this to complicated 🙂

Would converting NTSC tp PAL through compressor do the same nice job you think? I haven’t got Natress.
Did try to do it using Quicktime Pro, but Final Cut Pro stills says it’s 29.97 fps after exporting (I did set fps to 25 in Qt, and there it does show as such after processing :-?)
Thanks!

My experience tells me that you cant trust quicktime conversions, allot of strange things show up. Besides, quicktime would never be able to handle ntsc to pal properly.
If you use Compressor to convert your ntsc material to pal, then you could get ok results, but not nearly as good as from nattress.
For 100 bucks, nattress standard conversions is a bang fur the buck, go for it! Although it requires a littlebit learning, so check out the demo first to see if you like it. http://www.nattress.com

I’d like to get the natress plugin, but my time & money are too small for this onetime transfer. Could I use the demo to convert this one take of 40 min?
Or else: compressor seems to have problems: it keeps failing to export using a PAL preset and using a custom setting (to Qt .mov) produces a mov that won’t be red as a movie by either Qt or VLC.

If you use the Nattress demo then you will have the letters “demo” in bright green written over your video.
Regarding compressor I recommend just experimenting with different settings. The “advanced format conversions” work best. It’s not unusual for Compressor/FinalCut/Quicktime to have some strange bugs, and the only way around it is just to find “the other route to your destination”

Thanks. I’ll advise on buying the plugin-
In the mean time: what happens if I’d export to PAL 50 fps? A test on 10 sec I just did actually dosn’t look too bad. But then again I shouldn’t trust my monitor (LCD so no fields..)
