Okay. I have done this work 3 times now. Synched 2 cameras in a multicam clip.

 

However I have 2 problems.

 

1: When I select and move 2 angles the synch is not retained.

2: When I embed the multicam clip in a project or make a compound clip out of the mc clip, some sequences have no sound even though I have selected the proper audio track and ensured that that track is on inside the multicam clip.

 

Many thanks for help and hair transplants.

    What cameras are being used, and what is the format of the video after in FCPX and being edited?  This info will assist others to help you, likely, although I am only reading in FCPX.  I do know however, that earlier versions of FCP will lose edits if for example the video is still in H264 such as many cameras produce.

    That is info someone will need to intellegently respond.  Are both transcoded video sources using the same frame rate?

    Sorry to hear the problems, and hope it is not a bug.  I have been evaluating whether to move to FCPX from FCP 7 because of wanting a more efficient workflow to Vimeo.  Currently I use FCP 7 and its QT Conversion to produce Vimeo acceptable video.  Am also intrigued about mulitclips in FCXP since it can supposedly sync on audio track matching.  I successfully do multiclips in FCP 7 between material shot on my Nikon D800 and my Sony camcorders.  With both of those I shot in 24 fps, and transcoder and/or transfer at 1920 x 1080.

     

    Hope someone doing this or attempting this adds their response, soon.

    Hi,

     

    1:  What do you mean by 'move 2 angels' ?? You don't move the angels, you sync them, and edit the clip.

     

    2: Is the audio ok if you create a new project and drag the MC clip there and edit it??

    Are you sure you only switch video on the edit??

    Also in a multiclip you are only able to select one audio angle to playback, if you should want more than one you will need to handle that a little differently.

    You can combine multiple audio angles with full flexibility in 10.0.6.

    Check out yet another great episode of MacBreak Studio, where Steve Martin and Mark Spencer do a great job of explaining it: http://www.pixelcorps.tv/macbreak_studio (episode 190).

    Mark,

     

    Have you had success with material from cameras directly transferred into FCPX?  I wonder if when you transcode the 1440 x 1090 with MPEG Streamclip, it would be better to at that time expand to the full 1920 from the subsampled rate of 1440?

     

    Am I presuming too much to think that you see the edits at first, but they are not retained?  Or are you never seeing the result of an edit?

    Mark,

     

    Then you could set MPEG Streamclip to take it to 1920 x 1080 Pro Res, and test with that in FCPX.  The 1440 x 1080 is a convenience for file size, and in realty is meant to provide 1920 x 1080.  See:

    I can only guess that the multiclip routines might not be liking the 1440 x 1080, even though FCPX will play it.  I believe that if you were capturing direct, FCPX would change to the full raster 1920 x 1080, but cannot do that with the file you have provided it.  Just a guess.
