Encoding presets
The X-Agora Media Encoder offers four encoding presets.
• SQ: Standard Quality (MPEG-4). This is the default preset, and it is the
first one you should try, because it is the optimal tradeoff between
compression quality and disk space.
•
HQ:
High Quality (x264). This preset performs some compression, but
results in virtually unnoticeable quality loss.
•
XQ-S: Extra Quality Small Files (x264). This preset performs lossless
compression with relatively small files, but encoding and decoding are
longer than usual.
• XQ-L: Extra Quality Large Files (FFVHUFF). This preset performs lossless
compression with quick encoding and decoding, but the resulting files
are larger than usual.
H.3.2 Single video encoding
To start encoding an image sequence, drag the folder containing the images inside the
job list section. A new job appears in the list, and the new job can then be started, paused,
or stopped. To re-encode a video, repeat the process by dragging the video to be re-en-
coded instead.
H.3.3 Video package encoding
Video package encoding is useful when the image sequence or video has been produced
from a 2D or 3D template generated by the X-Agora Content Production Tool. A package
is simply a folder containing the sub-sections of the content to be played by each indi-
vidual projector output. The package contains several videos named after each projector's
internal identifier. Follow these steps to use video-package-encoding packages:
1. Place the crops.xml file in a folder with the image sequence and import
the folder into the Media Encoder.
An encoding job appears in the list. You can also choose to globally
apply a crop definition for all future encoding jobs by going in to the
application settings.
2. Press
Play
to start the job.
3. Import the generated video package into the Media Pane of your project.
4. Place the package on a Timeline.
