Autosyncing
Clips
When you capture footage that includes both audio and video, the system automatically establishes sync when it creates clips in the bin. Autosyncing applies to audio and video clips that have been captured separately, usually from two separate sources. Autosyncing creates a new subclip that displays sync breaks in the Timeline as though the audio and video were captured simultaneously.
Autosyncing is often used for 24p and 25p projects in which picture and sound were captured separately. These clips are often synced based on common film timecode, sound timecode, or auxiliary timecode.
You can also autosync any audio and video clips based on a user-defined IN point or OUT point relationship that you establish with marks. For example, you can use the slate as a common visual and audio reference for autosyncing the clips.
Use the following guidelines when autosyncing:

You can autosync audio clips with video clips only. To link two or
more video clips or audio clips, use the Grouping option described in
Understanding Grouping Clips.

You can create only one autosynced subclip at a time. You cannot
autosync numerous pairs of audio and video clips simultaneously.

If the audio and video clips do not have matching source or auxiliary
timecode, you must establish common sync frames. To do this, mark
IN points (or OUT points) on both clips before autosyncing. When you
autosync using this method, the whole clip is taken into the subclip.

If you are autosyncing clips of different lengths, the longer clip is
truncated to the length of the shorter clip; video clips override audio
clips.

If you autosync according to common timecodes that are staggered
(one clip starts later than the other), the later starting timecode
becomes the start of the new subclip. The clip with the earlier starting
timecode is trimmed accordingly.

To create an autosynced subclip:
1. | |
Highlight the two clips in the bin.
|
2. | |
Select Bin > AutoSync.
|
The Sync Selection dialog box opens.
3. | |
Select an option, based on the following:
|
– |
|
Film TC/Sound TC, if you are syncing clips with matching film
and sound timecode recorded in the field. This option appears
dimmed if you are not working on a 24p or 25p project.
|
– |
|
Inpoints, if you are syncing according to IN points set in both
clips.
|
– |
|
Outpoints, if you are syncing according to OUT points set in both
clips.
|
– |
|
Source Timecode, if the two clips have matching timecode.
|
– |
|
Auxiliary TC1–TC5, if the two clips have matching timecode in the
same Auxiliary Timecode column. Select an Auxiliary TC,
1áthrough 5, from the pop-up menu.
|
The subclip is created and named by default after the video clip with
the file name extension .sync.n, where n is the incremental number of
subclips created with the same name.
You can change the name according to preference. You can load an autosynced subclip into the Source monitor and immediately edit it into a sequence.
