Exported videos come out stretched?

[thouts]

I'm editing a 720x480 project and exporting it at 16:9 ratio. For some reason when I export the video and play it in quicktime, the video is stretched horizontally.

Any reason for this?

Because, without anamorphic flags, the aspect ratios aren't the same. 720 by 480 = 1.5 aspect ratio. 16:9 = 1.78.

You can't export 4:3 without it being stretched for 16:9. The best solution is in quicktime compressor to choose a widescreen res like 640x360 or 960x544 or 1280x720 then on your project choose reserve aspect ratio via crop which will turn your DV camera into a 16:9 camera source. It will crop out the top and bottom though :(
