Question

With Muti-clip gone from FCP X, is there a new way to sync two cameras with FCP X

Answer 1

I film with two cameras then copy the files from each camera into their own folders. I then use ClipWrap to convert the MTS files into AIC.  If the recording was one long contiguous session, many cameras will split the MTS files into 2GB chunks.  ClipWrap will Convert Multiple to Span to reassemble them properly.  With the AIC .MOV file from ClipWrap, I then use FCP X to Import the MOV files from camera 1 and camera 2.  I prefer to do it that way versus using FCP X Import from Camera.  I then move the clip from camera 1 onto the timeline in the "primary storyline" (FCP X terminology).  I drag the camera 2 clip above the camera 1 clip and line up the audio from the two cameras while that audio is still attached to the video so everything stays in sync.  FCP X has a way to automatically sync two soundtracks, but I have not gotten around to that yet.  With camera 2's clip attached to camera 1's clip as a "connected clip" above the camera 1 video, I then do an edit to go between the cameras as seems best to me.  When the connected clip of camera 2 video sits above the camera 1 video, it will take priority over the camera 1 video.  I then split camera 1's video clip taking out sections when I want to go back to the camera 1 view. Of course I can trim camera 2's clips until I get it the way I want it.  Since FCP X uses the magnetic timeline concept, and camera 2's clip is "connected" to the camera 1 clip, as you split and trim camera 2's clip, everything will stay in sync across the two camera "tracks".  When there is no camera 2 video above the camera 1 video, camera 1 video will be seen.  When camera 2 video is above camera 1 video, camera 2 video will be seen instead.  With a single editing pass, I can then do all the editing I need to go back and forth between two cameras.  The same concept is expandable to other camera "tracks" as long as you are using vertical position in the timeline to determine which camera is seen when.  If you would like for it to look like a multi-camera track composit like before FCP X, you can simply select all your clips and make a compound clip out of it.  You will then see the multiple camera clips side by side in a single "track".  Double click on that "clip" in that "track" to go into the structure and editing individual "tracks" around if needed.  Think of a compound track as what a sequence used to do.  Anyway, there may be other, and easier ways to do this, but with a single edit through my recording, I can easily and visually cycle back and forth between camera views.  It's just that things are called differently now ... and, as of this time, we do not have a single button camera switching function to let us view multiple cameras simultaneously and switch between them using a keystroke for each camera.  Still, I have a way to do it, and it has worked very well for me, in fact I was pleasantly surprised at how easily I could do multi-camera in post.  Hope this at least gives you one option.  Others may have a better way.  Best wishes.
