Format
: This determines the type of stream to which the video and audio 
are multiplexed.
t
Video
: The Video tab allows you to adjust the frame size, frame rate, field 
order, and profile. The default values are based on the preset you chose. Note 
that in this case, if you were outputting the video for actual deployment, 
you would want to change your Frame Height setting to 360 to eliminate 
the letterboxes shown in the figure, or choose a wide-screen preset. You 
would also want to change the Frame Rate setting to 23.976 to match your 
sequence setting and source footage.
t
Audio
: The Audio tab allows you to adjust the bit rate of the audio and, for 
some formats, the codec. The default values are based on the preset you 
chose.
t
FTP
: This tab primarily allows you to specify an FTP server for uploading 
the exported video when it is finished encoding. Fill in the appropriate FTP 
values supplied by your FTP host if you want to enable this feature.

Moving to the left side of the Export Settings dialog, look over the Source 
Settings drop-down list, where you can choose to export the work area bar 
selected in the sequence, a region selected using the handles directly above the 
drop-down list, or the entire sequence. This is useful when you want to export 
selected regions on the Timeline rather than the entire sequence.

Also on the left, note the Source/Output tabs, the latter of which shows a 
preview of the video to be encoded. It’s useful to view the video on the Output 
tab to catch errors like the letterboxing shown in the previous figure.
In terms of new or modified features, here are some highlights:
