FX1 to DVD downconvert

[Frank Aalbers]

Hello !

I tried a downconvert from 1080i upper field first to 480i lower firld first in Vegas so I can transfer it to DVD. The Vegas result was kind of blurry. So I tried it in Shake and I got a much better result.

I wish Vegas had a better resizing filter.

Yeah, Shake is noticably sharper. Same field order settings on both exports eh?

Yep ! Both upper field first to lower field first.

cool. Good to know.

But this quality is only visible on DVD if you also create high quality mpeg for DVD. I use 2 pass and variable rate to max 9800

Gives the best result for not much bigger file.

I'm asking since you are comparing Vegas (pc only) vs Shake that I believe is Mac only. You probably run on two platforms that is pretty strange for a MAC guy. Do you know of a good resizing program for Windows?

Not really ! Shake is also on PC

The older version that is. That's what I used

"Not really ! Shake is also on PC"

That is why I put the question mark on my title, I knew it was for MAC but this answer is a good piece of information. I never put too much attention on it. How do you like it?
I've a 4P Opteron monster machine and I like the maximum quality since I've has much computation power as money can buy on a single machine .

As I explained before . It's an older shake version available for PC.

Shake was also on PC before Apple got a hold of it.

I understand. Too bad is not on windows anymore. It is very expensive though, are you happy with it? I saw Aplle still sell an X86 version for Linux. I hate dual boot but I could do that in case.

Frank:

I downloaded your QuickTime clip, and compared it to the same footage downconverted to standard defination in Vegas 5 and my downconversion looks *much better* than yours.

I'm not sure how you did your downconvert in Vegas, since your result appears to take the 16:9 HDV frame at 1440x1080 pixels an convert it to standard definition 4:3 frame at 720x480 pixels using a stretch, which distorts the picture. You'd have to go out of your way in Vegas to do that! By default, it would letterbox the 16:9 into the 4:3 frame. Even if you were targeting widescreen SD (1.2121 pixel aspect), Vegas would still create small black bars on the sides since widescreen SD is slightly wider than 16:9 if it's 720 pixels wide.

So, exactly what settings in Vegas did you use to create this?

Just selecting the DV Widescreen template and setting quality to best.

Anything else I should do ?

And then how'd you get it in QuickTime format? Another format conversion? I still can't figure out why the frame is compressed (anamorphic) and doesn't have black bars on the sides. There's obviously some conversions happening *after* the Vegas downconvert.
