In general, it’s best to apply certain
processing options—such as deinterlacing and cropping—to an exported
file prior to encoding it to a particular format. Doing so can avoid
visual artifacts associated with performing the same tasks after
encoding. The cropping options and deinterlacing options you specify
prior to encoding are sometimes referred to as pre‑encoding
options.
Note: You can access the Noise Reduction filter option
(also considered a pre‑encoding task) by selecting the Filters tab.
Deinterlace the source prior to encoding
In the Output tab of the Export Settings dialog
box, select Deinterlace.
Crop the source prior to encoding
In
the Export Settings dialog box, click the Source tab.
Select the Crop button and do any of the following:
To crop the image interactively, drag the
sides or corner handles of the crop box around the source image.
To crop numerically, enter the values for Left,
Top, Right, Bottom, in pixels.
To constrain the proportion of the cropped image,
choose an option from the Crop Proportions menu.
Click the Output tab to preview how the cropped image
will appear.
To eliminate black areas resulting from cropping, select
Scale to Fit.
Note: When you actually encode the video, make sure that you
set the width and height values in the encoder to match these scale
height and width settings. The minimum size to which you can crop
an image is 40 pixels by 40 pixels.
