• Codec: This option allows you to select a codec for your proxy media: Apple ProRes
422 Proxy or H.264.
• ProRes Proxy: Creates higher-quality Apple ProRes 422 Proxy files. This option is
required for HDR and ProRes RAW source media.
• H.264: Creates smaller proxy file sizes. This option is appropriate for SDR
projects and source media.
• Frame Size: This pop-up menu allows you to choose a frame size for the transcoded
media (either as a percentage of the original or as maximum pixel dimensions).
• To specify a percentage of the source media frame size, you can choose Same as
Source (100%), 50%, 25%, or 12.5%.
• To specify maximum pixel dimensions, you can choose 3840 x 2160, 1920 x 1080,
or 960 x 540. Final Cut Pro maintains the source media aspect ratio without
exceeding these dimensions.
See Create optimized and proxy files in Final Cut Pro.
Note:
To control whether Final Cut Pro displays optimized, proxy, or original media in the
viewer, and whether video playback is optimized for quality or performance, choose the
corresponding options from the View pop-up menu in the upper-right corner of the viewer.
See
Control playback quality in Final Cut Pro.
Analyze Audio
• Fix audio problems: Analyzes audio and automatically corrects it for hum, noise, and
loudness. You can turn off automatic audio corrections at any time; after you do so, the
audio plays as originally recorded.
• Separate mono and group stereo audio: Analyzes audio channels and groups them as
dual mono or stereo, depending on the results of the analysis.
• Remove silent channels: Audio channels are analyzed, and silent channels are removed.
Note: You can retrieve the original audio configuration after import. See Configure audio
channels in Final Cut Pro.
Assign Audio Role
• Assign Audio Role: This pop-up menu allows you to override the automatic role
assignment process during import so that every imported clip is assigned to a role of
your choosing. You can specify one of the three default audio roles or a custom role
that you create yourself. See Override automatic role assignment for audio files during
import
. If the “Assign iXML track names if available” checkbox is selected, Final Cut Pro
detects iXML metadata tags in an audio channel and creates and assigns roles to the
corresponding audio components in the imported clips, based on the iXML names. See
Create custom roles automatically during import using iXML metadata.
