Experience working with JVC and Avid Media Composer v5
In mid June 2010 Avid will release a new version of its flagship editors. The versions included in this release will be Media Composer v5, NewsCutter v9 and Symphony v5. This
is a significant upgrade, and it includes many new features and improvements. Amongst other things, Avid has expanded support for file-based material.
About AMA 
AMA (Avid Media Access) is a plug-in architecture that will link material coming from file-based cameras. Originally released in 2009, AMA focused on mainstream file-based cameras
such as P2 and XDCAM. With the 2010-release of the editors, Avid expands AMA to include QuickTime files, RED files, MXF OP-1A files and much more. AMA reads the source files natively,
eliminating the need to copy, re-wrap or transcode your video before you can start editing. Your material can either be read directly from the memory card, or read from a copy on your
hard drive. When connecting a camera or memory card with video content, Avid editors will automatically recognize it, and your Avid editor will automatically import your video into a
bin - no user action required! AMA works the same way for PC and Mac.
AMA and JVC
Previously, AMA did work with MP4-flavoured material coming from the JVC ProHD camcorders. With the upcoming release of the editors, Avid now also supports QT files natively through
AMA. Thus, customers can now shoot the format of their choice, with the confidence that their Avid editor will be able to open, play and edit the material natively - with no
time-consuming re-wrap, copying or transcoding.
Limitations
This document is written based on a copy of a SDHC card with content shot by a GY-HM700E. A beta version of Media
Composer v5 was used. Features are subject to change. Avid makes no representations or warranties of any kind, either express or implied, with regard to this document.

AMA in use
If you do have the camera or original memory card available, demoing AMA is easy. Generally, all you need to do is to insert the card or connect the camera once the Avid editor is up
and running (with a project open). Your operating system will recognize the device and map it as a drive. As soon as that happens, your Avid editor will automatically load the clips
into a bin ready for you to use.
What’s best - QuickTime or MP4 recordings?
From a quality and performance point of view, it is all the same for the Avid editors. However, when choosing the MP4 (XDCAM EX) recording, it is richer in metadata. When working with
a copy of the MP4 files, you should always select ‘Link to AMA Volume…’ and browse for the folder that contains the BPAV-folder.
Demo AMA in Media Composer v5
Once you’ve created the links to your AMA clips, you can double click one of your clips to load it into the preview window and play it instantly. Putting clips to your timeline can
be done in different ways. For simplicity, either drag clips directly from the bin to your timeline, or double click the clip to load it into your preview window. Once in your preview
window, use spacebar to start playing the clip, and press [I] and [O] on the keyboard to mark Inpoint and Outpoint where you would like your new clip to start and stop. To send to the
timeline, click the Overwrite button.
