720P to 480P downconversion high quality

[Shane Ross]

The Kona LHe should do just a good of job as the Kona 3. I only had moire issues when it dealt with pictures made from line art. HD has more lines of resolution, so you don’t get the moire effect as easily as you do in SD.

thanks for the quick response shane.

I’m looking at it now and its MUCH better through the kona-lhe.

moire is completely gone, though there is some subtle aliasing
still happening but it is much better now.

there has got to be a way to make this look flawless like
a 1080 down convert through software.

Hey Chris,

I’d try the Compressor route, and be patient enough to let the frame controls take their time and do their magic. Depending on your materials, try short tests with different settings first.

Have a wonderful day.

Are you sure the sequence is set for a field order of “none”?

I agree, use the hardware first, then use Compressor.

[Chris Borjis]

I’m positive.
24p mpeg2 encoding is locked at progressive, there is no
option for interlacing. (in compressor)

I let compressor do it’s thing over the week end.
it took awhile to do, but looked absolutely lousy when
I looked at the dvd this morning. I always resize at
the highest quality setting no matter how long it takes.

massive horizontal line aliasing and moire patterns abound.

I was going to look at the de-interlace settings but its a progressive source,
so that shouldn’t matter……..or does it?

I’m looking at the DVD I made from letting the Kona Downconvert and its
way better and fully acceptable quality to my client.

Still though, compressor should be able to render it just as good
somehow.

I make ’24p’ DVDs from 720p24 material all the time.

I never have aliasing problems.

I export the HD material as a reference, bring that to Compressor and setup an MPEG2 preset.

[Chris Borjis] “I was going to look at the de-interlace settings but its a progressive source,

It does if it’s set wrong.

[Chris Borjis]

I’m doing the same process Jeremy.

what do you have the de-interlace settings for if I may ask?

[Jeremy Garchow]

Same as source.

[Chris Borjis]

I have that setting as well but I think thats for
field order not actual de-interlacing.

I’ll try and post detailed settings at work tuesday,
if it’s just one setting I have wrong I’m gonna pull some hair out.

[Chris Borjis] “I have that setting as well but I think thats for

What’s the difference in this case? You need to set it for same as source if you are coming from a 24p timeline to a ’24p’ DVD.

Deinterlace should be left at fast, as there’s no deinterlacing. I’d image ‘Same as source’ would turn off any deinterlacing.
