720 Anamorphic or 853?
Hey everyone,
I don’t even know what I would search for this, so apologies if it’s redundant.
We’re working in a DV50 720×480 Anamorphic 29.97 project. We have some outside clips that we would like to import that are 640×360. What’s the best way to resize these to bring them in?
Unfortunately, the 720×480 Anamorphic frame size is something I’m unclear on. Can someone explain or point me in a good direction? Is the acquisition frame size 720×480 but when it’s brought into FCP, it’s viewed as anamorphic which is 853?
Thank you!

Anamorphic DV clips check in on FCP as 853×480.

720×480 with an anamorphic pixel aspect ratio.

Right.
You don’t have to care about the pixels aspect.
As Jeremy say, just export 720×480.
The resultant pixels will be DV NTSC Anamorphic, because your original picture was 16×9.

Well, you have to care about the pixel aspect, otherwise it won’t work.
Anamorphic D1 footage has a pixel aspect of 1.2.
640×360 is square pixel. You will have to distort the footage in fcp ( I.e. change the pixel aspect ratio) to get it right.
Final frame size is still 720×480.

Jeremy,
If you take a 16×9 picture, and you divide it in 720×480 pieces, the resultant pieces will always be DV NTSC Anamorphic. Is impossible that you get something different.
Is nothing about codecs, pixels or even video; is about geometry.
If you do it in MPGStreamclip, for example, you don’t have a pixel choice. Is unnecessary and just can mess everything. As happens in Compressor.

You can’t be serious?

Raf, I don’t even know what you’re saying anymore.
640×360, the pixels are square.
720×480, the pixels are rectangular.
720×480, the pixels are even more rectangular.
How is that not changing the pixel aspect ratio? Squares to rectangles? Come on dude, you know better. It is about the aspect ratio.

Hi Jeremy,
Of course we are changing the pixels aspect.
What I say is that if we export any 16×9 picture (whatever the format, size, pixels,..) to 720×480, we can only get DV NTSC Anamorphic pixels.
WE don’t need to set the kind of pixels on exporting.
There is not way that you can get other kind of pixels.
740×480 any-other-kind-of-pixels would never make a 16×9 picture again.

In your 720×480 Anamorphic 29.97 timeline, simply place your 640×360 clip and scale it to fit the frame. Don’t use distort. FCP will scale the frame and pixels to make it anamorphic 720×480. If you absolutely must do it outside and use a software that doesn’t know about non-square pixels, then you’re right. it will have to be 853×480. Your math is right.
When I’m authoring NTSC DVDs and menus need to be 16:9, I often create graphics as 853×480. There’s no other way.
In PAL it would have to be 1024×576. That’s the ratio we use when exporting from a software like Resolve and we need it to go into a PAL anamorphic project.
