I have been working on a widescreen file taken from a PAL DVD. I am using the Nattress Converter to bring convert it from PAL to NTSC.
The original PAL file is 1280x720, 30fps.
It has to be brought into an NTSC timeline for the conversion. None of the presets fits the PAL specs so I finally settled on:
Frame size HD: (960X720) 16:9
Pixel Aspect Ratio: HD (960x720)
The file looks fine in the viewer, but has some black space left & right.
However, when I export it always come out squashed horizontally. I've tried some similar HD presets (none of the NTSC seem to come close) and always the same result.
