16:9 output

I was editing material from a 16:9 camera, I put the sequence also to anamorphic and did a quicktime (new codec out) but when viewing the quicktime it was 4:3 and obviously stretched. I imported it back in to fcp to see what if...and it was the same, I then checked the marker and it was back to anamorphic ...but that still does not resolve the output...
settings capture where ofcourse anamorphic...

any idea?

Yep, it's doing exactly as it should. Anamorphic 16:9 is still 720x480. It's up to your playback device to understand how to stretch it to fill the screen. Inside FCP the software stretches it in the canvas and viewer as long as the clip and sequence are set to 16:9. But playing back on a 4:3 monitor will give you squashed video. It will fill a 16:9 screen however.

If you play the video on a computer monitor using Quicktime, the proportions will be wrong no matter whether it's 4:3 or 16:9. Quicktime only understands square pixels, so it will just be 720x480 which is wrong for both 4:3 and 16:9. If you want to play it on a computer screen using Quicktime (like web streaming) you will need to resize your 16:9 to 854x480 or 640x480 for 4:3 (these are NTSC sizes, PAL 16:9 would be 1024x576 or 766x576 for 4:3).

If you're working with Quicktime on a computer monitor the pixels are always square. So the math is really simple. Pick a height for your image, multiply by 16 then divide by 9 to get the width. So a full size image would be (assuming you're in PAL-land):

576 x 16 / 9 = 1024

Or work the other way around, starting with your width:

1024 x 9 / 16 = 576

Or if you want the image to be 256 pixels wide then the height will be

256 x 9 /16 = 144

But if you're not working with Quicktime on a computer monitor then none of this matters. FCP will properly create a full resolution DV file using the default settings for anamorphic. Then it's completely up to the monitor or TV that you're watching the video on to figure out how to scale it.
