Help on proxies needed

I am trying to output SD 16:9 NTSC proxies from 1280 x 720p - 59.54 fps source material.
When setting this up in HDLink it converts to SD 4:3 720 x 480 and does not change to an expected 16:9 aspect ratio or (720 x 406)

I have the option of setting up letter boxed but want to keep a full frame 16:9 proxy of the original.
Here is the configuration I have set for HDLink, does this look right?

Your settings are correct, you are only assuming the output is wrong. If there is no letterboxing the 720x480 frame is to be displayed at 16x9. I use this feature a lot for 16x9 DVD creation.

Thanks David, actually the output displays only in a 4:3 frame but it should be 16:9.
the 960 output (I think 1 for 1 pixel) displays correctly in 16:9 frame.

I am looking for the bext way to output low res proxies in a 16:9 frame.
By the way, this is an excellent addition to HDlink!

I think you are mistaken. Load the 720x480 clips into VirtualDub and set the display ratio to 16x9, does the image look correct?

Hi David, I imported the clip into virtual dub and by default its set to a 4:3 aspect ratio, yes I can make it 16:9 by changing aspect ratio but when importing the clip to CS5 with scale to frame size enabled in a 16:9 timeline it shows as Pillar Boxed, see attached image.

Curiously, when looking at file properties in media info, the (SD NTSC 16:9) proxy shows an aspect ratio of 4x3, however the (Proxy 960 x auto - square pixel) proxy shows correctly as 16:9. To me it looks to be definitely outputting a 4x3 aspect ratio.

I have attached screen shots of the pillar box file in CS5 as well as mediainfo from both test files I created showing the difference in aspect ratios of the 2 test files.
Cheers -

AVIs are maybe interpreted 4x3, when they are fact 16x9 (as they are in this case), just interpret your footage as 16x9. It is working fine. I just reconfirmed myself.
