HD to SD DVD aliasing issues

[Ernie Santella]

Jeremy, tried that as I changed the Frame controls to Progressive and not auto. No dice.

There has to be something about when it’s coming into DVDSP. All the files look fine when watched on my mac monitors. It’s just when it get’s to the DVD that it’s weird. (I’ve enve tried different DVD players and the HD versions look bad.

Could it be something with using a DVCProHD 720p60 timeline with 30 fps material?

Aren’t you editing @ 30fps and not 60?

You have exported a reference movie and brought this movie to compressor, right?

I’m using the FCP 720p60 timeline preset. The footage is all at 30fps. It looks perfect on all my HD monitors. And yes, I am exporting as a QT reference movie. I do the exactly the same thing for all my SD projects with no issues.

This is driving me crazy.

[Jeremy Garchow]

Why aren’t you editing @ 30 if all of your footage is at 30?

[Ernie Santella]

I don’t have that preset in my FCP settings window? I have:

DVCPro1080i50
DVCPro1080i60
DVCPro1080p25
DVCPro1080p30

DVCPro720p50
DVCPro720p60

No DVCPro720p30. Where can I load that setting?

[Jeremy Garchow]

Do you have a Kona card or did you capture firewire? Sorry for all the questions.

[Ernie Santella]

Kona 3 Card. I see that setting in Easy Setup, but when I make a sequence, I only get 720p50 or 60, no 30?

Ask all the question you can. There has to be one simple thing I’m missing?

Can you change your timeline sequence settings to 720p30

[Jeremy Garchow]

The Kona card does not come with a 30p easy setup, you have to make one. It’s easiest to duplicate the 24p easy setup and change the frame rate to 30.

That being said, was all this material from tape? If so, you are good as you can edit @ 60, but if your media is @ 30 you might have some problems. I guess the proper question is, is your media captured @ 30 or 60?

THAT being said. Any chance you can post a still of this aliasing? I want to make sure that what we are talking about is aliasing.

It was all captured from tape with the Easy Setup 720p30 preset. Does everyone have to modify a 720p24 timeline to be 30? That’s seems dumb, that they don’t make a 720p30 setting?

To be correct in what your saying, you create a new seq (which comes up as 720p24 (not 24pA) and then change the Editing Timebas to 29.97, correct? Why will this make a difference?

I will try to post a pic of the aliasing. As you don’t see it on any of the mac files, just the final DVD. I will have to figure out the best way to grab a shot off the DVD.

Do you mean, you don’t see this in the MPEG2 files or you only see it on a monitor through a DVD player?

Sorry more questions.
