Enter values for the width and height so the desired height is 9/16 of the desired width (to determine this value, multiply the width by 0.5625),
Example frame sizes using this ratio:
If you are exporting from the native DV-NTSC frame size of 720 x 480, set the output frame size to be 720 x 405.
A smaller 16:9 frame size would be 400 x 225
By using the formula above, you can come up with your own values for smaller web widescreen aspect ratios.
More info in my 2002 Ken Stone article. Not much has changed since then – except the possibility to do this in compressor rather than cleaner.
