I am a little bit confused about the blanking of 1:1.85 aspect ratio content in a HD container.
When one does the math the visible area is 1920x1038 (rounded).
In a psf HD-SDI frame this should look like this:
Line 593 and 31 should be black and line 594 and 32 should have image content.
But I noticed that some people use 1920x1040.
In this case: Line 30 and 593 are the last black ones and line 31 and 594 are the first ones with image content.
Now I am wondering what aspect ratio is the correct one. Can someone please enlighten me?
