Dynamic Media Video Profiles

Dynamic Media already comes with a predefined Adaptive Video Encoding profile. The settings in this out-of-the-box profile are optimized to give your customers the best viewing experience possible. When you encode your primary source videos using the Adaptive Video Encoding profile, during playback, the video player automatically adjusts the quality of the video stream based on the Internet connection speed of your customers. This action is known as adaptive bitrate streaming.

The following are other factors that determine the quality of your videos:

• Resolution of the uploaded primary source video

  If the MP4 video was recorded at a lower resolution, such as 240p or 360p, it cannot be streamed in high definition.

• Video player size

  By default, the “Width” in the Adaptive Video Encoding profile is set to “Auto.” Again, during playback, the best quality is used based on the size of the player.

See Best Practices for Video Encoding.

See also Best Practices for Organizing your Digital Assets for using Processing Profiles.

When you are done creating the Video Profile, you apply it to a folder or multiple folders. See Apply a Video Profile to folders.

To define advanced processing parameters for other asset types, see Configure asset processing.

Adaptive video encoding presets

The following table identifies best practices when encoding profiles for adaptive video streaming to mobile and tablet devices, and desktop computers. You can use these presets for any aspect ratio video.

About using smart crop in Video Profiles

Smart crop for video is an optional feature available in Video Profiles. It is a tool that uses Adobe Sensei to automatically detect and crop the focal point in any adaptive video or progressive video that you have uploaded, regardless of size.

Supported video formats for smart cropping include MP4, MKV, MOV, AVI, FLV, and WMV.

The maximum supported video file size for smart crop is the following criteria:

• Duration of five minutes.
• 30 frames per second (FPS).
• File size of 300 MB.

Adobe Sensei is limited to 9000 frames. That is, five minutes at 30 FPS. If your video has a higher FPS, the maximum-supported video duration decreases. For example, a 60 FPS video must be two and a half minutes long to be supported by Adobe Sensei and smart crop.

To use smart crop for video, you create an adaptive or progressive video encoding profile. As part of your profile, use the Smart Crop Ratio tool to select pre-defined aspect ratios. As an example, after you define your video encoding presets, you can add a “Mobile Landscape” definition with an aspect ratio of 16x9, and a “Mobile Portrait” definition with an aspect ratio of 9x16. Other aspect or crop ratios from which you can choose to include 1x1, 4x3, and 4x5.

You can toggle video smart crop in the Video Profile to either on or off using the slider to the far right of Smart Crop Ratio in the user interface.

After you create and save your Video Profile, you can apply it to the folders you want.

See Apply Video Profiles to specific folders or Apply a Video Profile globally.

Create a Video Profile for adaptive bitrate streaming

Dynamic Media already comes with a predefined Adaptive Video Encoding profile-a group of video upload settings for MP4 H.264-that is optimized for the best viewing experience. You can use this profile when you upload your videos.

However, if this predefined profile does not meet your needs, you can choose to create your own adaptive video encoding profile. As a best practice, when you use the setting Encode for adaptive streaming, all encoding presets that you add to the profile are validated. This functionality ensures that all videos have the same aspect ratio. In addition, the encoded videos are treated as a multibitrate set for streaming.

When you create the video encoding profile, you notice that most encoding options are pre-populated with recommended default settings to help you. However, if you select a value other than the recommended default, it can result in poor video quality during playback and other performance issues.

So, for all MP4 H.264 video encoding presets in the profile, the following values are validated to ensure that they are the same across individual encoding presets in the profile, making adaptive bitrate streaming possible:

• Video Format Codec - MP4 H.264 (.mp4)
• Audio Codec
• Audio Bitrate
• Keep Aspect Ratio
• Two Pass Encoding
• Constant Bitrate
• H264 Profile
• Audio Sampling Rate

If the values are not the same, you can continue creating the profile as is. However, adaptive bitrate streaming is not possible. Instead, users experience single-bitrate streaming. It is recommended that you edit the encoding settings to use the same values across individual encoding presets in the profile. (The Video Profile/preset editor enforces parity of the adaptive video encoding settings if “Encode for adaptive streaming” is enabled.)

Create a Video Profile for progressive streaming

If you choose not to use the option Encode for adaptive streaming, all encoding presets that you add to the profile are treated as individual video renditions for single-bitrate streaming or progressive video delivery. Also, there is no validation to ensure that all the video renditions have the same aspect ratio.

The supported video format codecs are H.264 (.mp4) and WebM.

Apply a Video Profile to folders

When you assign a Video Profile to a folder, any subfolders automatically inherit the profile from its parent folder. As such, you can assign only one Video Profile to a folder. As such, consider carefully the folder structure of where you upload, store, use, and archive assets.

If you assigned a different Video Profile to a folder, the new profile overrides the previous profile. The previously existing folder assets remain unchanged. The new profile is applied on the assets that are added to the folder later.

Folders that have a profile assigned to it are indicated in the user interface using the name of the profile that appears in the card name.

You can apply Video Profiles to specific folders or globally to all assets.

You can reprocess assets in a folder that already has an existing Video Profile that you later changed. See Reprocessing assets in a folder.

Apply a Video Profile to specific folders

You can apply a Video Profile to a folder from within the Tools menu or if you are in the folder, from the Properties. This section describes how to apply Video Profiles to folders both ways.

Folders that have a profile already assigned to it are indicated by the display of the profile’s name directly below the folder name.

See also Reprocess assets in a folder after you have edited its processing profile.

Apply a Video Profile to folders by way of the Profiles user interface

1. Select the Experience Manager logo and navigate to Tools > Assets > Video Profiles.
2. Select the Video Profile that you want to apply to a folder or multiple folders.
3. Select Apply Profile to Folders and select the folder or multiple folders you want use to receive the newly uploaded assets and select Apply. Folders that have a profile already assigned to it are indicated by the display of the profile’s name directly below the folder name while in Card View.
   You can monitor the progress of a Video Profile processing job.

Apply a Video Profile to folders from Properties

1. Select the Experience Manager logo and navigate to Assets and then to the folder that you want to apply a Video Profile to.

2. On the folder, select the check mark to select it and then select Properties.

In addition to applying a profile to a folder, you can also apply one globally so that any content uploaded into Experience Manager assets in any folder has the selected profile applied.

See also Reprocess assets in a folder.

To apply a Video Profile globally:

• Navigate to CRXDE Lite to the following node: /content/dam/jcr:content. Add the property videoProfile:/libs/settings/dam/video/dynamicmedia/<name of video encoding profile> and select Save All.

  

• You can monitor the progress of a Video Profile processing job.

Monitor the progress of a Video Profile processing job

A processing indicator (or progress bar) is displayed so you can visually monitor the progress of a Video Profile processing job.

You can also view the error.log file to monitor the progress of an encoding job, to see if encoding is finished, or to see any job errors. The error.log is found in the logs folder where your instance of Experience Manager is installed.

Remove a Video Profile from folders

When you remove a Video Profile from a folder, any subfolders automatically inherit the removal of the profile from its parent folder. However, any processing of files that has occurred within the folders remains intact.

You can remove a Video Profile from a folder from within the Tools menu or if you are in the folder, from the Folder Settings. This section describes how to remove Video Profiles from folders both ways.
