Changes to Match Source presets
When exporting video files in H.264 or MPEG-2 format, Adobe Media Encoder allows you to automatically match the
video settings of the source file using Match Source presets. Match Source functionality has been expanded to the
QuickTime, MXF OP1a, and DNxHD MXF OP1a formats. The October release of Adobe Media Encoder CC includes
new Match Source presets that lets you easily apply the new settings.
DNxHD/MXF OP1a presets
The DNxHD/MXF OP1a presets function is a little different from the traditional match source behavior. There are no
controls to do a match source on the specific parameters. Use these presets to simplify your workflow when you want
to get your media into an MXF wrapper. You do not have to choose from any settings and can use this preset directly.
The following source media are supported:
• XDCAM HD/EX
• AVCI
• XAVC
• IMX
• DV
• DNxHD
QuickTime
QuickTime codecs can now automatically match the parameters of your source file. You can apply a QuickTime preset
and select Match Source from the Export Settings dialog.If the destination codec does not support a specific value such
as frame size, it will use the closest available.
For more information about Match Source presets, see the Export settings reference section.
Multiplex during encoding
Adobe Media Encoder can now multiplex MPEG-2 streams while encoding the source. Previously, multiplexing was
handled in a separate step; a separate video and audio file was first created and then the individual files were
multiplexed at the end of an encode. When handling larger files, this separate multiplexing process made it seem as
though Adobe Media Encoder had frozen.
Multiplexing during encoding has the following advantages:
1 Increased encode throughput for MPEG-2.
2 Decreased disk usage.
Note: PCM audio format is not multiplexed during encode.
GoPro CineForm codec support
Note: The preset names have been updated in the Adobe Media Encoder December 2014 release. See
Updated preset names
for GoPro ConeForm codec section.
There is a new GoPro Cineform codec available natively in a QuickTime wrapper that supports resolutions upto 4K and
includes alpha channel support.
