Time Code
As a NTSC video is in 29.97fps, it takes more than a second to display 30 frames. To
correct this difference, drop frame Time Code drops frame numbers.

Time Code Check this option to use NTSC Drop Frame Time Code.
Scaling and Letterboxing
If your source and your target have different frame sizes, there are two different ways
to handle this scenario. For example, you may have a 16:9 source file that needs to
be encoded to a target file with a 4:3 aspect ratio frame size. Because of the different
frame sizes, you either have to scale and crop your Source file, or add black bars to
the video to compensate for the difference. If you want to crop your source file, you
should use the Crop video filter in the Source tab.
