Create a multi-camera source sequence

Select the clips in the Project panel and select Clip > Create Multi-Camera Source Sequence.

Choose how you want to synchronize your clips. 

• In Points, Out Points: Set specific in and out points for each clip to align them manually. This option requires precise timing and is suitable for smaller projects or when audio synchronization is not crucial. Learn more about marking clips for synchronization.
• Timecode: If your clips have accurate timecode, select this option to synchronize them based on their timecode values. 
• Select Create Single Multicam Source Sequence to combine the clips into a single multi-camera sequence. Use this option when the coverage from the individual shots has gaps and you want to create a sequence that preserves the gaps. If you don't choose this option, only overlapping clips are combined, and clips with no overlaps are left unused.  You can assign a group of clips a Camera Angle or Camera Label that can be referenced during multicam creation. Groups of clips with matching Camera Label or Camera Angle metadata fields are placed on their own track during the metadata creation process.  This same concept applies to external audio or field audio.  
• Select Ignore Hours if each clip has a timecode that starts at a different hour but otherwise overlaps in the timecode.
• Select other timecode options:
  • Linear Timecode:  Choose this option to synchronize the clips using the timecode in the clip's audio track.
  • Sound Timecode: Choose this option to synchronize clips using a separate audio recorder.
  • Aux Timecode: Choose this option if you have embedded timecode information that isn't the primary timecode but can provide additional synchronization data.
• Audio: Use this option to synchronize clips based on a specific audio track. This is helpful when a consistent audio source is present in all clips (like a clapboard or voiceover). 
• Clip Marker: If you've added markers to specific points in your clips, you can use them for synchronization. This is useful for aligning clips based on specific events.

Choose sequence preset options.

• Sequence Preset: Choose a preset based on your project's requirements. The sequence preset Automatic is selected by default and is based on the video format of the Camera 1 clip. In most scenarios, the Automatic preset is the appropriate setting. For advanced workflows, like editing a sequence using proxy resolution clips, you can choose a specific sequence preset. You can then use higher-resolution/frame-size clips for the final edit.     
• Offset Audio by: If a separately recorded audio track is out of sync with the video clip, add a frame offset using the Offset Audio by option. For the audio-only clip, you can enter video frames in the range of -100 to +100 for the sync offset. 
• Move Source Clips to Processed Clips bin: Select this option to move the generated source clips to a Processed Clips bin. If a Processed Clips bin does not exist, Premiere Pro creates one before moving the clips into it. Clips not meeting the synchronization criteria are left outside the Processed Clips bin. This option makes it easy to identify clips not used in the resulting multicam source sequence.

Choose audio sequence settings.

• Camera 1: Select Camera 1 when only the audio from Camera 1 is used in the editing sequence. Multicam editing is enabled for only the video portion of the source sequence. If you use A/V clips to create this sequence, the audio tracks for all audio associated with video 1 are unmuted. Other audio in the source sequence is muted. If you use audio-only clips with video or A/V clips, the audio-only clips are placed in the topmost tracks and are unmuted. Other audio (from linked clips) is muted and placed in lower tracks. Each track's channel assignments and panning are set to transfer each source channel to independent output channels (up to 32). The number of unmuted channels of source audio determines the number of active output channels of the sequence.

• All Cameras: Select All Cameras to use all audio channels in the source clips. This setting is similar to the Camera 1 setting. Only the video portion of the source sequence is multicam-enabled. Audio-follows-video is not supported for this setting. All audio is unmuted (up to 32 channels). The number of unmuted channels of source audio determines the number of active output channels of the sequence.
• Switch Audio: Select this option when you want the audio to switch with its linked video. This setting unmutes all audio. It enables multicam editing on both the video and audio of the source sequence when the audio follows the video setting enabled in the Program Monitor. This setting also maps multi-mono source audio into a single adaptive audio track. In addition, the audio-follows-video editing setting switches this single track with the video. If audio-only clips are included in the selection of clips, the audio-only clips are placed in tracks below any linked clips. Empty video tracks are created to match up with every audio-only track.

Choose audio channel presets.

• Automatic: Reads the audio type of the first clip and uses this mapping.
• Mono: Maps to as many mono channels as output channels in the source sequence.
• Stereo: Maps to stereo tracks based on the number of output channels in the source sequence.
• 5.1: Maps to 5.1 tracks based on the number of output channels in the source sequence.
• Adaptive: Maps to Adaptive based on the number of output channels in the source sequence.

Choose how to display camera names.

• Enumerate Cameras: Select this option to automatically number the camera angles in the sequence name. This can be helpful for identification and organization.
• Use Track Names: Display the camera angles using track names.
• Use Clip Names: Display the camera angles using clip names.

Select OK.
