USING ADOBE PREMIERE PRO 147 Editing sequences and clips Selecting a sequence preset To ensure that a sequence is created to match the characteristics of an asset, drag the asset in the Project panel to the New Item button at the bottom of the Project panel. This prevents many mistakes that are made when entering sequence settings incorrectly or choosing the wrong sequence preset. A sequence can contain different types of assets, in different formats, and with various different parameters. However, Premiere Pro performs best when the settings for a sequence match the parameters of most of the assets used in that sequence. To optimize performance and reduce rendering times, find out the following parameters for the primary assets you want to edit before creating a sequence. After learning the asset parameters, you can create a sequence with settings to match. Before capturing assets from a tape-based device, learn these parameters also, so that you can select the correct capture settings. • recording format (for example, DV, or DVCPRO HD) • file format (for example, AVI, MOV, or VOB • frame aspect ratio (for example, 16:9, or 4:3) • pixel aspect ratio (for example, 1.0, or 0.9091) • frame rate (for example, 29.97 fps, or 23.976 fps) • time base (for example, 29.97 fps, or 23.976 fps) • fields (for example, progressive or interlaced) • audio sample rate (for example, 32 Hz, or 48 Hz) • video codec • audio codec You can use the Properties panel to discover many of these parameters for your assets.

Selecting a sequence preset
To ensure that a sequence is created to match the characteristics of an asset, drag the asset in the Project panel to the
New Item
button at the bottom of the Project panel. This prevents many mistakes that are made when entering
sequence settings incorrectly or choosing the wrong sequence preset.
A sequence can contain different types of assets, in different formats, and with various different parameters. However,
Premiere Pro performs best when the settings for a sequence match the parameters of most of the assets used in that
sequence. To optimize performance and reduce rendering times, find out the following parameters for the primary
assets you want to edit before creating a sequence. After learning the asset parameters, you can create a sequence with
settings to match. Before capturing assets from a tape-based device, learn these parameters also, so that you can select
the correct capture settings.
recording format (for example, DV, or DVCPRO HD)
file format (for example, AVI, MOV, or VOB
frame aspect ratio (for example, 16:9, or 4:3)
pixel aspect ratio (for example, 1.0, or 0.9091)
frame rate (for example, 29.97 fps, or 23.976 fps)
time base (for example, 29.97 fps, or 23.976 fps)
fields (for example, progressive or interlaced)
audio sample rate (for example, 32 Hz, or 48 Hz)
video codec
audio codec
You can use the Properties panel to discover many of these parameters for your assets. See “
Viewing clip properties
on page
111. Alternatively, you can use a third-party application, such as the freeware, MediaInfo, or GSpot Codec
Information Appliance. To find the codecs used to generate a file, you can also choose Window > Show Movie
Inspector in Apple QuickTime Player.
Assets can use codecs not supported natively by Premiere Pro. Often, you can edit these assets after installing the
relevant codecs. However, beware of installing untested codecs that may themselves introduce severe problems with
your computer system.

Create a custom sequence preset
To customize most sequence settings, you must start a new sequence, select an existing preset, and change its settings.
Every editing mode does not support every possible frame rate. To create a custom preset with, for example, a 23.976
fps frame rate, select “Desktop” as the Editing Mode (called “Custom” in Premiere Pro CS5.5 and later). Then, select
23.976 frames/second from the Timebase menu.
