Rendering One or More Sequences
You can use any of the above commands to render all effects or a subset of effects in
one or more sequences.
To render an entire sequence:
1 Do one of the following:
 In the Browser, select one or more sequences.
 Open a single sequence in the Timeline.
2 If necessary, choose Sequence > Settings, then select the Render Control tab in the
Sequence Settings window to specify quality settings for rendered effects, as well as to
choose which effects are and are not rendered.
3 Choose the combination of Timeline playback states you want to render from the
Sequence > Render All submenu.
4 Choose a render command from the Sequence > Render All submenu.
5 If your project has not yet been saved, Final Cut Express HD prompts you to save
your project.
A status window appears showing the rendering progress. Click Cancel to stop rendering.
All rendered frames are written to disk, even if rendering is canceled.
More About Audio Render Options
Two of the audio rendering operations create render files in very specific ways.
 Item Level rendering options: Renders the audio items that need to be resampled to
match the sample rate of the sequence, as well as audio items with filters applied
to them, as item level render files. Audio mixing is still done in real time, and
mixing performance improves since audio resampling and audio effects no longer
consume real-time processing resources.
 Mixdown: Renders all the audio in a sequence to a single group of render files, one
for each audio output assigned to the selected sequence. This can improve playback
performance by eliminating the need for Final Cut Express HD to do any real-time
mixing or audio effects playback. The Mixdown command is a nondestructive
operation and doesn’t change any of the audio clips in the sequence.
When using either the Item Level option in the Render Selection and Render All
submenus, or the Mixdown command in the Render Only submenu, audio is
rendered at the highest quality regardless of the setting chosen in the Audio
Playback Quality pop-up menu in the General tab of the User Preferences window.
