Pan & Zoom handles 16:9 incorrectly

Post by Joe Linn »

I am working on a 16:9 HDV project. I wanted to insert a still image and zoom in on it. The still image is 16:9. If I just insert the image on the timeline, the resulting video has the correct proportions. As soon as I add a pan & zoom filter, the image looks like 4:3 stretched to 16:9. The rectangles on the pan & zoom dialog are 4:3 ratio and it appears to do all its scaling based on 4:3. Is this a limitation/bug with pan & zoom, or is there a way I can tell pan & zoom to use a 16:9 aspect ratio?

Thanks

Is non-square pixel rendering turned on in the project settings?

If so turn it off.

Hi Terry,

Thanks for the help. That fixed the problem. Only I actually needed to turn ON non-square rendering. HDV resolution is 1440x1080 (which is a 4:3 ratio) but it is displayed as 16:9, so it does use non-square pixels. I turned on non-square rendering and now I am getting exactly the results I expected.

Thanks again!

Which way it goes (non-square on/off) depends on the resolution of your sources.

1440x1080i isn't a true 4:3 but is instead an anamorphic 16:9, meaning 16:9 data horizontally squeezed into a 4:3 frame. 720p and 1920x1080i are "straight" (unsqueezed) formats.

The anamorphic format is what was messing you up and I was presuming un-squeezed.
