As you might have noticed, the aspect ratio option has been changed. The new option has 4 choices as shown above. Here I explain the feature of each option.

1. Keep DAR

This will keep the original DAR (display aspect ratio) for the output file. In this case, changing the resolution won’t affect the display aspect ratio.

2. Keep PAR

This will keep the original PAR (pixel aspect ratio) for the output file. This is usually used when you are applying cropping (but no resizing which cause screen geometric change).

3. Set DAR

This will set the DAR of output file to your specified value (the value can be entered or chosen in the blank next to the aspect ratio option). This is usually used when you change the DAR of the original file or apply cropping + resizing to fit for screen geometric size different from the original target.

4. Set PAR

This will set the PAR of output file to your specified value (the value can be entered or chosen in the blank next to the aspect ratio option) . This is usually used when you change the PAR of the original file. This is usually used when you know the target PAR and want to control the DAR through resolution.
