2.
Use one of the following methods to align the audio and video so the video output is synchronized.
• If you used a slate or a loud clap for your synchronization point, you can align the events to within a frame of each other
using the audio waveforms:
a.
Roughly align the audio waveforms by dragging events in the timeline.
b.
Use the Zoom controls at the bottom-right corner of the timeline to zoom in on the waveform.
c.
Verify Quantize to Frames is enabled because you want video frames to be aligned even if the audio is slightly out of
alignment.
d.
Drag a track’s border to make the tracks taller and view large waveforms.
e.
Use Shift+Up Arrow to magnify the waveforms if necessary.
f.
Click the event you want to move and press 1 or 3 on the numeric keypad to nudge the event by frames to the left or
right.
• Synchronizing a video event:
Note:
These steps require snapping to be enabled, so if you have not already done so, turn snapping on by clicking the
Enable Snapping button ( ). For more information, see the online help.
a.
Solo the video track.
b.
Position the cursor at the synchronization point and drag the event’s snap offset so it snaps to the cursor. For more
information, see the online help.
c.
Repeat steps a and b for each clip.
d.
Drag the cursor to a snap point, and then snap the other clips to the cursor.
If the cameras were not genlocked together (shooting at the same cadence) you may find one to be up to half a
frame ahead of the other. Unless your scene has lots of fast motion, this is acceptable; just be sure to get them as
close as possible on the timeline.
3.
Verify alignment:
a.
Drag the Level slider on the top track to set its opacity to 50 percent.
b.
Find a portion of the video with good movement and verify the motion is the same in both clips and that one clip does
not lead the other.
If the cameras were not genlocked together (shooting at the same cadence), you may find that one clip is up to half a
frame ahead of the other. Unless your scene has lots of fast motion, this is acceptable.
4.
Select both video events, right-click one of the events, and choose Pair as Stereoscopic 3D Subclip.
One video event is deleted from the timeline, the active take for the event is set to the new multistream subclip, and a new
multistream clip is added to the Project Media window. If you view the clip properties for the new subclip, you’ll see that the
Stereoscopic 3D Mode is set to Pair with next stream.
