Upload and encode videos uploading-and-encoding-videos
To create single video or Adaptive Video sets for delivery to the Web or mobile devices, you first upload your primary video files to ۶Ƶ Dynamic Media Classic. ۶Ƶ Dynamic Media Classic encodes videos to MP4 format and it publishes video in the following file formats:
-
MP4: ۶Ƶ Dynamic Media Classic recommends MP4 as the preferred video file format. Use MP4 files for the following:
- HTTP Dynamic Streaming on desktops.
- HTTP Live Streaming (Apple’s streaming protocol).
- Progressive video delivery to Android™, BlackBerry®, and Windows® mobile devices
۶Ƶ Dynamic Media Classic offers two workflows for uploading video files:
-
Pre-encoded Videos: You upload MP4 files directly to ۶Ƶ Dynamic Media Classic. With this workflow, files are not encoded at the time you upload them. The files are pre-encoded in preparation for delivery to the desktop and to mobile devices.
-
Primary source videos: Upload primary source video files and, at upload, encode these files to MP4 files. Encoded videos are labeled “Video” in the Browse panel. ۶Ƶ Dynamic Media Classic supports the encoding of video files in many formats.
-
Make sure the primary source video files that you want to encode are supported.
-
Choose a video encoding preset.
-
۶Ƶ Dynamic Media Classic also generates video thumbnails. You can learn more about video thumbnails, how to obtain their URLs, and modifying poster frames.
See Work with video thumbnails.

When you use an Adaptive Video encoding preset or multiple single-encoding presets, the result is an Adaptive Video Set that is automatically created with multiple video encodings. You can also manually create an Adaptive Video Set by selecting individual videos.
Only MP4 and M4V file types are created when you generate an Adaptive Video Set either automatically or manually.
Supported video file types for encoding supported-video-file-types-for-encoding
The following table lists video file types (with permitted video codecs) that you can encode to MP4 or OGV format when you upload files. The table lists file formats and codecs:
-
Video file formats: Similar to a ZIP file, a video file format determines how files are contained in the video file. A video file usually contains multiple tracks — a video track (without audio) and one or more audio tracks (without video) — that are interrelated and synchronized. The video file format determines how these different data tracks and metadata are organized.
-
Video codecs: A video codec describes the algorithm by which a video is encoded. A video player decodes the video according to its codec and then displays a series of images, or frames, on the screen. Codecs minimize the amount of information that video files are required to store to play video. Rather than information about each individual frame, only information about the differences between one frame and the next is stored. Because most videos change little from one frame to the next, codecs allow for high compression rates, which result in smaller file sizes.

Best practices for video encoding best-practices-for-video-encoding
The following are best-practice tips for encoding source video files in ۶Ƶ Dynamic Media Classic.
Source video files source-video-files
When you encode a video file, use a source video file of the highest possible quality. Avoid using previously encoded video files because these files are already compressed, and further encoding creates a subpar quality video.
The following table describes the recommended size, aspect ratio, and minimum bit rate that your source video files must have when you encode them:
Obtain a file’s metadata obtaining-a-file-s-metadata
You can obtain a file’s metadata by viewing its metadata in ۶Ƶ Dynamic Media Classic, using a video-editing tool, or using an application designed for obtaining metadata. Following are instructions for using MediaInfo, a third-party application, to obtain a video file’s metadata:
- Go to this Web page: .
- Select and download the installer for the GUI version, and follow the installation instructions.
- After installation, either right-click the video file (Windows® only) and select MediaInfo, or open MediaInfo and drag your video file into the application. You see all metadata associated with your video file, including its width, height, and fps.
Aspect ratio aspect-ratio
When you choose or create a video encoding preset for your primary video file, make sure that the preset has the same aspect ratio as the primary video file. The aspect ratio is the ratio of the width to the height of the video.
To determine the aspect ratio of a video file, obtain the file’s metadata, and note the file’s width and its height (see Obtain a file’s metadata). Then use this formula to determine the aspect ratio:
Width / Height = Aspect ratio
The following table describes how formula results translate to common aspect ratio choices:
For example, a video that is 1440 width × 1080 height has an aspect ratio of 1440/1080, or 1.33. In this case, you choose a video encoding preset with a 4:3 aspect ratio to encode the video file.
Data rate data-rate
The data rate (also called the bit rate) is the amount of data that is encoded to make up a single second of video playback. The data rate is measured in kilobits per second (Kbps).
When you choose a video encoding preset, remember to account for the target end user’s connection speed. Choose a preset with a data rate that is 80 percent of that speed. For example, if the target end user’s connection speed is 1000 Kbps, the best preset is one with a video data rate of 800 Kbps.
This table describes the data rate of typical connection speeds.
Resolution resolution
Resolution describes a video file’s height and width in pixels. Most source video is stored at a high resolution (for example, 1920 × 1080). For streaming purposes, source video is compressed to a smaller resolution (640 × 480 or smaller).
Resolution and data rate are two integrally linked factors that determine video quality. To maintain the same video quality, the higher the number of pixels in a video file (the higher the resolution), the higher the data rate must be. For example, consider the number of pixels per frame in a 320 × 240 resolution and a 640 × 480 resolution video file:
The 640 × 480 file has four times more pixels per frame. To achieve the same data rate for these two example resolutions, you apply four times the compression to the 640 × 480 file, which can reduce the quality of the video. Therefore, a video data rate of 250 Kbps produces high-quality viewing at a 320 × 240 resolution, but not at a 640 × 480 resolution.
Because resolution and data rate are linked, you have two options when encoding video:
- Choose a data rate and then encode at the highest resolution that appears best at the data rate you chose.
- Choose a resolution and then encode at the data rate necessary to achieve high-quality video at the resolution you chose.
When you choose (or create) a video encoding preset for your primary video file, use this table to target the correct resolution:
FPS (frames per second) fps-frames-per-second
In the United States and Japan, most video is shot at 29.97 frames per second (FPS); in Europe, most video is shot at 25 FPS. The film is shot at 24 FPS.
Choose a video encoding preset that matches the FPS rate of your primary video file. For example, if your primary video is 25 FPS, choose an encoding preset with 25 FPS. By default, all custom encodings use the primary video file’s FPS. For this reason that specifying the FPS setting when you create a video encoding preset is not necessary.
Video encoding dimensions video-encoding-dimensions
For optimal results, select encoding dimensions such that the source video is a whole multiple of all your encoded videos.
To calculate this ratio, you divide source width by encoded width to get the width ratio. Then, you divide source height by encoded height to get the height ratio.
If the resulting ratio is a whole integer, it means that the video is optimally scaled. If the resulting ratio is not a whole integer, it impacts video quality by leaving leftover pixel artifacts on the display. This effect is most noticeable when the video has text.
As an example, suppose that your source video is 1920 × 1080. In the following table, the three encoded videos provide the optimal encoding settings to use.
Encoded video file format encoded-video-file-format
۶Ƶ Dynamic Media Classic recommends using MP4 H.264 video encoding presets. Because MP4 files use the H.264 video codec, it provides high-quality video but in a compressed file size.
Work with video encoding presets working-with-video-encoding-presets
Primary video files created with video production equipment and video-editing software are often too large and not in the proper format for delivery to online destinations. To convert digital video to the proper format and specifications for playback on different screens, you can transcode video files (a process also known as encoding). During the encoding process, the video is compressed to a smaller, efficient file size. It does so for optimal delivery to the Web and to mobile devices.
۶Ƶ Dynamic Media Classic gives you a library of predefined video encoding presets that reflect the most common encoding settings used today. These encoding presets are optimized for playback on target screens. In addition, administrators can create their own video encoding presets to customize the size and playback quality of videos to end users. All video encoding presets, whether out-of-the-box from ۶Ƶ Dynamic Media Classic, or custom-made, output video in the MP4 file format.
On the Video Presets screen, administrators can set up and manage video encoding. They can do the following:
- Activate and deactivate video encoding presets.
- Create a video encoding preset.
- Edit video encoding presets.
- Delete Video Presets.
Any video that you upload to ۶Ƶ Dynamic Media Classic or that you encode in ۶Ƶ Dynamic Media Classic is treated as “video.” In other words, this asset classification means that you can deliver the video for playback on desktops, mobile devices, or both. For example, you can preview these types of videos in ۶Ƶ Dynamic Media Classic. You can also generate URLs (using the Copy URL feature) and code that you can embed (using the Embed Code feature) for use with video players, on websites, and so on.
See Preview videos in a video viewer.
See Link a video URL to a mobile site or a website.
See Embed the video viewer on a Web page.
For video assets that you upload and encode in ۶Ƶ Dynamic Media Classic, video is delivered in the following file format:
MP4 H.264 Use MP4 files for the following:
- HTTP Dynamic Streaming on desktops.
- HLS (HTTP Live Streaming, Apple’s streaming protocol).
- Progressive video delivery to Android™, BlackBerry®, and Windows® mobile devices.
Any other video format and codec is treated as a “Primary Video.” This asset classification means that the video is a source video file and cannot be used for delivery playback on desktops or mobile devices. For example, you cannot preview these types of videos in ۶Ƶ Dynamic Media Classic. You cannot generate Copy URLs or Embed Code for use in video players, on websites, and so on.

When users choose transcoding options, the tooltip appears when they move the pointer over the name of the preset in the Upload Job Options dialog box. Playback Device Choose the device that the video is intended to play back on. The options are Computer (desktops), Mobile (iPhone, iPad, Android™); or Tablet (iPad only). This setting automatically determines the appropriate video and audio codec used during encoding. Target Data Rate Enter the average Internet connection speed (in kilobits per second) of the target end user. You can enter the rate or drag the slider to enter it. The User Connection Speed spectrum lists typical speeds for broadband, DSL, mobile, and dial-up connections. This setting automatically determines the combined video and audio data rate. In other words, the amount of data that is encoded to make up a single second of video playback. The higher the data rate, the better the quality of the resulting video. However, data rates that are too high result in large file sizes that create subpar viewing experiences for users with a low bandwidth. As a best practice, strike a balance between high and low data rates. Try to aim to create an adequate quality playback experience without alienating users who have narrow bandwidths. Aspect Ratio The aspect ratio is the ratio of the width to the height of the video. The first two aspect ratios listed below are commonly used to display video horizontally:
- 4:3: Used for almost all standard definition TV broadcast content.
- 16:9: Used for almost all wide-screen content and movies on High-Definition Television (HDTV).
- Auto-scale: (Default) A single-encoding preset that works with any aspect ratio to create videos for delivery to mobile, tablet, and desktop. Uploaded source videos that are encoded with this preset are set with a fixed height. However, the width automatically scales to preserve the video’s aspect ratio (width to height ratio).
- Custom: Used when you want to define a non-standard video size.
- The aspect ratio that you choose determines the width and the height settings for the Resolution Size; the width and the height value automatically scale to the proper aspect ratio.
Resolution Size Resolution size, expressed by the number of pixels wide by the number of pixels high, determines the size. Enter a width and a height value in pixels or drag the slider to enter these values. The Resolution spectrum lists typical resolution sizes. The width value and the height value automatically adhere to the aspect ratio that you selected. For example, if you select 4:3 as the aspect ratio and enter 400 for width, 300 is entered automatically for height. If you selected Auto-scale for the Aspect Ratio setting, then the Width value for the Resolution Size is automatically set to Auto. Select Preview so you can open a browser window and see your resolution choices there. Encode File Suffix Enter a suffix. This suffix is appended to the resulting encoded video file. You can enter a hyphen and underscore in the name; blank spaces and special characters are not allowed. Other Settings ۶Ƶ Dynamic Media Classic determines all other encoding settings automatically according to best-practice encoding guidelines. -
