HD to SD Anamorphic Question
on Mar 5, 2009 at 4:23:44 pm

I'm making an SD Anamorphic 16:9 DVD from HDV material and I have a question.

Could someone tell me if the overscan areas will or will not be seen on a widescreen TV using a DVD player that up-res's the image to 1080i?

Then I also want to confirm that when the image appears letterboxed on an SD 4:3 TV that the overscan on the sides remains out of frame while the top and bottom (of course) remain in the picture.

Thanks for your help.

TVs handle overscaning differently. As a practice there should never be anything in the overscan picture that you don't want viewed while everything that needs to be viewed should fall within action or title safe. I would never rely on overscanning to eliminate poor framing of a shoot.

Most playback on computers play the entire image.

Actually, I wanted to shrink my image by about 1% and include as much of the overscan as possible. I know it varies and I run the risk of showing black around the edges if I shrink it too much. But just wanted to see if this was a workable solution because I shot something a bit too tight in HDV, you know what I mean and I need it to breathe just a little bit.

If the DVD Player is connected digitally (with an HDMI cable) then you will see the entire frame. If it is connected with analog cables (Component, S-Video, Composite) then you will lose some of the frame to overscan.
