Scratch Removal
405
Replacing flaws with material from a nearby frame or field lets you correct flaws in more complex
footage. For example, a flaw on an image such as a face might be very difficult to cover using
material from the same frame or field — there might be no other area of the face in that image that
shows similar tones, textures, and highlights. In this situation, it is better to replace the flaw by
copying the same part of the face from an earlier or later frame that does not contain the flaw.
This method also provides an alternative for dealing with uniform areas such as sky since you can
replace a flaw with the same area from a nearby clean frame.
When you use material from a nearby frame to replace a flaw, you cannot see the whole of the nearby
frame as you work. Instead, you see the replacement area in the shape you draw to cover the flaw, and
you use parameter sliders in the Effect Editor to adjust which portion of the nearby frame appears.
Selecting Material to Use When Correcting Flaws
When you isolate a flaw as a new segment to correct it, you must include enough clean material to
make the correction. The Intraframe tools you use for removing flaws cannot reference frames
outside the segment that you isolate.
In some cases, you can take all the clean material you need from the same frames that contain the
flaw. In other situations, you need to include one or more completely clean frames along with the
flawed frames in the segment you isolate.
For example, if a flaw persists across several frames in footage that includes no motion, the simplest
way to correct the flaw is to include one clean frame before or after the flawed frames and use
replacement material from the clean frame to cover the flaw in all the other frames. For more
information on using replacement material from different points in your footage, see “Examples of
Scratch Removal Parameter Settings” on page 412.
Detecting Video Dropout in 24p or 25p Material
Because of the way some Avid editing applications handle the display of 24p or 25p material, you
might not be able to see video dropout when you use the default Fast Frame Display mode.
To ensure that you can see dropout when you are working with 24p or 25p material, turn off Fast
Frame Display mode by selecting Special > Fast Frame Display. (When Fast Frame Display is
deselected, there is no check mark beside it in the menu.) You can then see every line of the full 24p
or 25p frame.
For more information on how Media Composer displays 24p or 25p material, see “Displaying 24p
and 25p Media” in the Help.

When you turn off Fast Frame Display, you slow down Media Composer’s display capabilities.
If you turn off Fast Frame Display to check for flaws, you should turn it on again before you
proceed with other editing operations.
Selecting Frame or Field Processing When Using Scratch Removal
To select frame or field processing when using Scratch Removal:
1. Move the position indicator to the effect’s icon in the Timeline.
2. If you are not in Effect mode, enter Effect mode, for example by clicking the Effect Mode button.
For more information, see “Entering Effect Mode” on page 32.
