Improve data transfer times by limiting the maximum size of images and videos that
users of mobile applications attach to cases. For example, you can conserve bandwidth when a
mobile app synchronizes with the server by adjusting the attachment compression parameters, such
as the video clip format and duration, or the maximum image size and quality.
Before you begin: Add the
Attach content control to the
layout. For more information, see:
Adding controls.
By adjusting the attachment compression parameters you limit the size of files that are
transferred between a mobile device and the server. When you select the
Infinite option for any of the parameters, files are attached in
their original format or length, which results
in increased data
transfer.
Files
of lower resolution, shorter duration, or
lower
quality, all help reduce
the file size and boost
data transfer. The settings apply when a user records a new video or takes a
new photo, but do not apply to pre-recorded media. Media files are compressed on
user
devices
before users upload them to the server. Note: Due to
the
different memory limitations of
different
user
devices,
you might not be able to successfully attach large files even when you limit the maximum
file size.
