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 functionality 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 鈥淲idth鈥 in the Adaptive Video Encoding profile is set to 鈥淎uto.鈥 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.

NOTE
To generate a video鈥檚 metadata and associated video image thumbnails, the video itself must go through the encoding process in Dynamic Media. In 蜜豆视频 Experience Manager, the Dynamic Media Encode Video workflow encodes video if you have enabled Dynamic Media and set up video cloud services. This workflow captures workflow process history and failure information. See Monitor video encoding and YouTube publishing progress. If you have enabled Dynamic Media and set up video cloud services, the Dynamic Media Encode Video workflow automatically takes effect when you upload a video. (If you are not using Dynamic Media, the DAM Update Asset workflow takes effect.)
Metadata is useful when you are searching for assets. The thumbnails are static video images that are generated during encoding. They are required by the Experience Manager system and used in the user interface to help you visually identify videos in the Cards view, Search Results view, and the Asset List view. You can see the generated thumbnails when you select the Renditions icon (paint palette) of an encoded video.

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.

About using smart crop in video profiles about-smart-crop-video

Smart crop for video 鈥 an optional feature available in Video Profiles鈥 is a tool that uses the power of artificial intelligence in 蜜豆视频 Sensei. It automatically detects and crops 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).
  • 300-MB file size.

蜜豆视频 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 蜜豆视频 Sensei and smart crop.

Smart Crop for Video

IMPORTANT
For video smart crop to work, you must include one or more video encoding presets with your video profile.

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 鈥淢obile Landscape鈥 definition with an aspect ratio of 16脳9, and a 鈥淢obile Portrait鈥 definition with an aspect ratio of 9脳16. Other aspect or crop ratios from which you can choose from include 1脳1, 4脳3, and 4脳5.

Edit a video encoding profile with smart crop

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 creating-a-video-encoding-profile-for-adaptive-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. When you use the setting Encode for adaptive streaming 鈥 as a best practice 鈥 all encoding presets that you add to the profile are validated to ensure that all videos have the same aspect ratio. In addition, the encoded videos are treated as a multi-bitrate set for streaming.

When you create the video encoding profile, 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 creating-a-video-encoding-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.

Depending on which mode you are running, the supported video format codecs are the following:

  • Dynamic Media-Scene7 mode: H.264 (.mp4)
  • Dynamic Media-Hybrid mode: H.264 (.mp4), WebM

Use custom-added video encoding parameters using-custom-added-video-encoding-parameters

You can edit an existing video encoding profile to take advantage of advanced video encoding parameters that are not found in the user interface when you create or edit a Video Profile in Experience Manager. Add one or more advanced parameters 鈥 such as minBitrate and maxBitrate 鈥 to your existing profile.

To use custom-added video encoding parameters:

  1. Select the Experience Manager logo, then navigate to Tools > General > CRXDE Lite.

  2. From the CRXDE Lite page, in the Explorer panel on the left, navigate to the following:

    /conf/global/settings/dam/dm/presets/video/*name_of_video_encoding_profile_to_edit

  3. In the panel on the lower-right side of the page, from the Properties tab, specify the Name, Type, and Value of the parameter you want to use.

    The following advanced parameters are available to use:

Name
Description
Type
Value
h264Level
H.264 level to use for encoding. Normally this parameter is automatically determined based on the encoding settings you are using.
String

10 * h264 level

For example, 3.0 = 30, 1.3 = 13)

No default value.

keyframe
The target number of frames between keyframes. Calculate this value so it can generate a keyframe every 2-10 seconds. For example, at 30 frames per second, the keyframe interval should be 60-300.

Lower keyframe intervals improve stream seeking and stream switching behavior for adaptive video encodings and may also improve the quality for videos that have lot of motion. However, because keyframes increase a file's size, a lower keyframe interval usually results in lower overall video quality at a given bitrate.
String

Positive number.

Default is 300.

Recommended value for DASH or HLS is 60-90. (To use DASH for your videos, it must first be enabled on your account. See Enable DASH on your account.)

minBitrate

Minimum bitrate to allow for variable bitrate encodings, in Kbps (kilobits per second).

This parameter only applies when Use Constant Bitrate is deselected in the Advanced tab when you create or edit a video encoding profile.

See also Bitrate.

String

Positive number, in Kbps.

No default value.

maxBitrate

Maximum bitrate to allow for variable bitrate encodings, in Kbps.

This parameter only applies when Use Constant Bitrate is deselected in the Advanced tab when you create or edit a video encoding profile.

See also Bitrate.

String

Positive number, in Kbps.

No default value. However, the recommended value is up to two times of the encoding bitrate.

audioBitrateCustom
Set value to true to force a constant bitrate for the audio stream, if supported by audio codec.
String

true/false

Default is false.

Recommended value for DASH or HLS is false. (To use DASH for your videos, it must first be enabled on your account. See Enable DASH on your account.)

Apply a video profile to folders applying-a-video-profile-to-folders

When you assign a video profile to a folder, any subfolders automatically inherit the profile from its parent folder. This rule means that 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 by the appearance of the profile name in the card name.
