This option should only be checked if your output is destined for an interlaced display.
So if you are exporting for the web where progressive is desired don't check the box.
WM automatically deinterlaces.
Thanks for the reply! So, I guess your answer means that the Adobe documentation is wrong because it says "Select this option if the video content in the sequence is interlaced and you are exporting to a noninterlaced medium." Is my interpretation of your reply correct and should I therefore submit a correction request to Adobe?
How should I go about contacting Adobe regarding this documentation correction that needs to be done? Should I just go to the documentation page and reference this thread and point out that the documenation is wrong?
