Add video and audio eects
Add and remove eects
Compressor provides a variety of video and audio eects that you can use to improve the quality
of the video and audio in the transcoded le. Video eects modify specic visual aspects of your
source media, such as brightness and contrast, color, noise levels, and interlacing. Audio eects
modify sound aspects in your source media, such as dynamic range, peaking, and equalizer eects.
To add an eect to an output le, you add the eect to a setting and then use that setting to
output your source le. You can view both the source le and a preview of the transcoded le in
the preview area.
Important: As with other properties you add to a setting, eects you add to a built-in setting are
not saved for future use. If you want to save the eects you apply to a setting, you must create a
custom setting by duplicating the built-in setting that contains the eects. For more information,
see Create custom settings on page 21.
Add a video or audio eect
1 Do one of the following:
•
In the batch area, click an output row to select a setting that is part of a job.
•
In the Settings pane, select a custom setting from the Custom area. (If the Settings pane is
hidden, press Shift-Command-1.)
2 In the Video inspector or Audio inspector, choose an item from the Add Video Eect pop-up
menu or from the Add Audio Eect pop-up menu.
If the inspector pane is not visible, click the Inspector button in the upper-right corner of the
Compressor window.
After you choose an eect from the pop-up menu, its adjustable properties appear at the
bottom of the inspector. For detailed information about these properties, see Video eects on
page 77 and Audio eects on page 79. You can apply multiple video and audio eects. When you
add an eect, a checkmark appears beside the eect name in the pop-up menu.
3 Preview eects that you’ve added to a setting by clicking the Play button in the preview area.
Because eects may interact in unexpected ways, be sure to preview the transcoded le each
time you add an eect.
Note: Depending on your system, the source media le type, and the number of eects in the
job, the preview area showing the lter settings may update at a lower frame rate than the
source frame rate.
Change the order in which eects are applied to a source le
Because eects are processed one by one during transcoding—starting with the rst item in the
list—it’s important that you order the eects appropriately. For example, it’s sensible to place a
text overlay eect last in your list of eects so that its text color isn’t modied by other eects.
If you preview the transcoded le and don’t like the results of an eect, you can try reordering
the eects in the eects list to improve the results of the transcoded le.
m Select an eect and drag it to new location in the list of eects at the bottom of the Video or
Audio inspector.
