Hi there.
Just a quick question about DAR.
I am encoding Star Wars Attack of the Clones with Megui and x264. I want to encode anamorphically without resizing. My source is PAL DVD.
After cropping I am left with an image 720 x 432.
If I tick "Maintain Resolution and set AR in encoder" in Megui and don't resize then it sets the AR at 47:20 in the x264 encoder config page. This equates to a DAR of 2.35:1
However doing the maths the DAR should really be 2.37:1. (720 wide gets expanded to 1024 with a PAR of 64:45 and 1024/432 equals 2.37:1). The simplified fraction for 1024/432 is 64/27.
What do people think. Should I leave the AR in the x264 config page at 47:20 (which gives an image 1015 x 432) or manually change it to 64:27 which would give the 1024 x 432 image again.
BTW I know that the Sample Aspect Ratio in config page should be labelled DAR.
Thanks
