Adobe After Effects - Manual (Page 97)

Note:
Note:
In all of these cases, the information is used to make decisions about how to interpret data in the imported footage item—to tell After
Effects about the input footage. The interpretation settings in the Interpret Footage dialog box should match the settings used to create the source
footage file. Do not use the interpretation settings to try to specify settings for your final rendered output.
Generally, you don’t need to change interpretation settings. However, if a footage item isn’t of a common kind, After Effects may need additional
information from you to interpret it correctly.
You can use the controls in the Color Management section of the Interpret Footage dialog box to tell After Effects how to interpret the color
information in a footage item. This step is usually only necessary when the footage item does not contain an embedded color profile.
When you preview in the Footage panel, you see the results of the footage interpretation operations.
Jeff Almasol provides a script on his redefinery website that you can use to make guessing the 3:2 pulldown, 24Pa pulldown, or alpha channel
interpretation more convenient.
Select Preview in the Interpret Footage dialog box to preview the results of the settings made in this dialog box before you accept the
changes.
