Pre-Production Workflow for Avid Media Composer v5

 

GoPro CineForm Studio support for Avid Media Composer version 5 and 6 is through Avid's AMA QuickTime interface.  Previous versions of Media Composer are not compatible with CineForm media.

AVI versus MOV: On Mac, Media Composer requires CineForm MOV files.  If you have CineForm AVI files they can always be rewrapped to MOV using HDLink on Windows or ReMaster on Mac (part of all Neo family products).  (Note: Media Composer on Windows will play CineForm AVI files but there seems to be a bug in the Media Composer audio handling at the time this was written).

Spatial Resolution: Media Composer is an HD application and will not support media higher in resolution than 1920x1080.  (The slight modification to this statement is that if you have a 2K CineForm file, it will be decoded at full resolution and then center-cropped (to 1920x1080) by Media Composer so you lose horizontal and vertical edges.

Broadcast: We recommend shooting up to HD resolution (1920×1080) for broadcast distribution, even if you’re shooting with the SI-3D rig (which supports both HD and 2K).  The reason is that you have a straightforward real-time 3D workflow at HD, including the ability to finish for broadcast distribution at HD.  

Film: Many film projects will prefer to shoot at 2K or other resolutions above HD.  In this case you will use a somewhat traditional offline/online model with Media Composer.  You can edit CineForm media as offline in MC and use CineForm tools to assist with your conform afterwards.

Workflow Steps:

1.  Create your CineForm 3D media.

2.  Link your CineForm media through the Media Composer AMA interface.

3.  Launch First Light and import the same CineForm media into First Light.  Often you'll select side-by-side as the stereo viewing mode within First Light.

4.  In Composer Settings, select the Stereo Layout you prefer in the MC window.

5.  If you need to make stereo or color adjustments on CineForm media while editing:

a.  bring First Light into the foreground and make the adjustment;
b.  bring MC into the foreground and hit Play - you'll see the adjustment immediately.

6.  At completion of editing, if you used CineForm online files, you're ready to export to your preferred format. 

a.  Full-resolution CineForm stereo file:
      i.  Select Left eye in the CineForm 3D view control; then render to
           a full-resolution CineForm file (this will make the Left eye).
     ii. Select Right eye in the CineForm 3D view control; then render to
           a full-resolution CineForm file (this will make the Right eye).
    iii. Bring both Left and Right eye files into First Light and mux into
           a new CineForm stereo file.

b.  Side-by-side for broadcast or DVD/Blu-Ray:
        i. Select side-by-side mode in First Light.  Then render from Media Comoser
            to your preferred codec (including CineForm).

7.  For film workflows above HD you can export an XML from Media Composer, then filter it in Film Scribe, then use the resulting XML with ReMaster (Mac only right now) to create DPX files for use in numerous finishing tools.  Please see the separate Tech Note that describes the finishing workflow on Mac.  (Windows finishing later).
