pixel size HD anamorphic

Recommended Posts

Guest Typo

Hi

 

sorry for my english

My question is??

 

what is the size in pixel of the format HD ( 1920x1080) anamorphic

When you convert it in square pixel???

 

For example:

the size of SD D1 pal is 720x576 (anamorphic ,16:9) = 1024x576 in square pixel

 

 

Can i make my film in HDTV with an anamorphic lens?

 

And what is the best comp preference in AE for import this footage?

How i interpret the footage?

Thanks

It's 1 - 1920 x 1080 is 16 / 9 square pixel with no change in pixel aspect.

the awnser of my question is:

 

If i shot my film in hdtv (1920x1080) in 16-9 with anamorphic lens

I must interpret it in AE with anamorphic 2:1 pixel aspect ratio

and it is aprox 3840x1080 pixels in square pixel aspect ratio

 

Is this ok???

I'm not sure that's the way I would work, since working in a comp that's almost 4K would be kind of difficult and slow. I'd work in the comp at 1920X1080 and put an adjustment layer at the top, squishing the comp in half. Bring in all of your material (text, or whatever), and make sure it goes under the adjustment layer. When you're ready to render, disable the adjustment layer, and then your text should stretch vertically and render anamorphic with the rest of the footage so you're not losing any resolution.

 

I haven't actually tried this, but it seems to work ok in my head.

Typo - yeah you're right with the 2:1 aspect ratio - But I wouldn't bother de-anamorphacising the footage to 3840 x 1080 - it'll really slow everything down and when you put everything back onto tape it'll have to go back to 1920 x 1080 and lose all of the quality. Work at 1920 x 1080 with a pixel aspect ratio of 2 set up in your comp and use after effects pixel aspect correction so you can see everything at the right size.

 

No point in calculating stuff you'll have to throw out.
