Keep original aspect ratio and cropped aspect ratio
To keep original aspect ratio, users need make sure the “Display aspect ratio” and the”Size (pix)” in “Settings” option are all set as “Original”.

If you want to keep the same aspect ratio in your final output files, do remember to set the Video “Size (pix)” in “Settings” section as the same ratio as display aspect ratio. For example, if you want to export a file with “3:2″ aspect ratio, firstly, you choose “3:2″ in “Display aspect ratio”, and then go to “Settings” section to adjust the Video “Size(pix)” as 720×480 or 1440×960. After finished, click “OK” to confirm.
