You can now deliver high quality, short-form videos without worrying about
byte size or bloated web pages. Image and Video Manager automatically creates and delivers
optimized videos with the correct bit-rate, resolution, and format based on your customer's
device.
You open Policy Manager when you want to
create, edit, or push policies to staging or production. A policy in Image and Video
Manager is a set of criteria applied to a video. These criteria may contain different
quality settings.
The Event Viewer in Control
Center records Image and Video
Manager - Policy Manager events and details.
When you
manage Image and Video Manager policies, there are 2 types of policies you can
manage:
The default policy: Image and
Video Manager applies the default policy unless a request includes a
parameter indicating a valid custom policy name. The default policy contains
the default settings that determine how Image and Video Manager generates
derivatives for the policy set. The default policy appears in the Policies
section after you after you open Policy Manager, select a contract and a
policy set, and click Manage Policies. You can edit the default policy.
A custom policy: You can
create and edit custom policies for videos to apply different quality and
resolution settings. Once you've defined your policies, use Image and Video
Manager parameters to associate the correct policy to each image or video
request.
The steps for editing the default policy or creating or editing a custom policy
are the same.
Note: Image and Video
Manager does not optimize videos that go over 5 minutes in duration, 256 MB in
size, or 3.7 M in pixel area (1920x1920). This limits the videos to a 1080 pixel
resolution.
To configure your policy
settings:
How to
Go to > CDN > Image and Video
Manager.
Select your contract in the Contract field.
Select a policy set name in the Policy Set Name field.
You should select the policy set name that you specified in Connect Your Videos. A policy set is a collection of policies grouped in a way that makes sense
for your organization. For example, you might organize your policies according
to your hostnames. That would allow you to apply policies to all videos at a
particular hostname.
Click Manage
Policies.
A list of policies appears in the Policies section.
If you want to edit the default
policy, select the Actions menu and click View/Edit Staging/Production
Policy. If you want to create a new custom policy, click
Add New
Policy. If you want to edit a custom policy, select the Actions
menu and click View/Edit Staging/Production Policy.
The Video Policy Editor appears.
Select a fixed quality option
for all your derivative videos.
High. If you specify
High, the video has the highest visual quality and you save the least in
byte size.
Medium High. If you
specify Medium High, the video has a high visual quality and a low level of
byte size savings.
Medium. If you
specify Medium, the video has medium visual quality and you do save some
amount in byte size.
Medium Low. If you
specify Medium Low, the video has a low visual quality and you have a small
byte size.
Low. If you specify
Low, Image and Video Manager produces the lowest visual quality in order to
have the smallest byte size.
Note: On April 30, 2020 the video
quality options were updated from three (Low, Medium, and High) to five
(Low, Medium-Low, Medium, Medium-High, and High). The new options offer a
greater range of visual quality and byte size reduction. High now allows you
to optimize your videos using even less byte reduction to preserve the video
quality. Low now allows you to produce an even lower quality video to
further reduce the byte size.
Note: Image and Video Manager
automatically updates any policies created before the new fixed quality
options were available. If you created a policy using High, your policy will
now use Medium-High to preserve the visual quality options you originally
selected. If you created a policy using Low, your policy will be
automatically updated to Medium-Low. No changes are required if you selected
Medium. Medium applies the same level of optimization before and after the
new options were introduced.
Select one of these options in
the Derivative Video
Resolutions:
853x640. The
video will appear at a lower level resolution and is also smaller in size.
1280x720. The
video has medium level of resolution.
1920x1080.
Image and Video Manager produces a high-definition video.
Select Placeholder Video if you
want add a specific placeholder video that appears when a user first requests a
video, but before Image and Video Manager processes the video. If you do not
specify this, the original video plays during the processing time. If your
original video is very large or you do not want your customers to see the
original video, using a placeholder video is an option.
You cannot save a policy, you must save it
and activate it on the on the staging server. For more information on saving and testing
your policy on the staging server, see Test on Staging.
