The following information provides important additional details on how the Safe Color
Limiter effect operates:
• The Safe Color Limiter automatically takes variations in broadcast formats into account,
for example the differences between PAL and NTSC material, and the difference in the
setup offset between NTSC and NTSC-J.
• Because the primary purpose of safe color limiting is to ensure that video is acceptable
for SD broadcast, all limiting by the Safe Color Limiter effect is performed in the 601
color space. When you are working with HD material in the 709 color space, the Safe
Color Limiter converts the material to the 601 color space to apply limiting, and then
converts back to the 709 color space.
• Like many other Avid effects, the Safe Color Limiter effect supports both 8-bit and
16-bit processing. For more information, see “Using 16-Bit Processing Support for
Rendered Effects” on page 172.
Applying the Safe Color Limiter Effect
A common scenario for applying the Safe Color Limiter effect is to apply it to filler on the
top track in the Timeline so that the effect acts on the entire duration of the sequence.
Depending on your needs, you might also want to apply a Safe Color Limiter effect to a
single segment in a sequence, or to multiple selected segments.
To apply the Safe Color Limiter effect:
1. Set the default safe color limits you want the Safe Color Limiter effect to use.
For more information, see “Managing Safe Color Warnings” on page 819.
2. (Option) If you want to apply the effect across the entire duration of the sequence, add a
new video track in the Timeline, for example, by selecting Clip > New Video Track.
3. Do one of the following:
t If you are applying the Safe Color Limiter effect to the entire duration of the
sequence, drag the effect from the Image category of the Effect Palette, and drop it
on the empty top video track.
The top video track shows filler material with the Safe Color Limiter effect applied
to it, and your Avid editing application limits all of the video material in the
sequence according to the limit values you set in step 1.
t Apply the effect to one or more segments using standard methods, as described in
“Applying Effects From the Effect Palette” on page 36.
Your Avid editing application limits the video in the segment or segments to which
you applied the effect according to the limit values you set in step 1.
