Assets


Each video or audio media clip that gets uploaded to the online video platform is automatically transcoded (or encoded) to different formats in order to ensure playback on all devices and bandwidths. These formats are called assets and can be found in the assets tab in the media clip details. The specific assets that are created by the online video platform can vary by publication settings, but we maintain a standard set that will be used in most publications.

1.0 | Video Assets

Video Assets

Video is encoded to various asset types:

1.1 | MP4_MAIN

Our main asset type is MP4_MAIN and will be served to most users. It features a Standard Definition resolution along with an average bandwidth. There may be multiple MP4_MAIN assets using different resolutions and bandwidths in some publications.

1.2 | MP4_HD

Similar to the MP4_MAIN asset, with a High Definition resolution (above 720p). It features settings that ensure smooth playback and encoding that is more suited to high resolution video.

1.3 | MP4_IPOD

This asset type can be considered as the most basic asset, since it has great compatibility with a broad range of devices, including (hence the name) the iPod. However, file size and quality are sacrificed for this compatibility and the Blue Billywig player favours other assets if they can be played.

1.4 | MP4_TIMELINE

This asset will only be used within the Timeline Editor, and will never be served to the user.

1.5 | IMAGESEQUENCE

An asset that is used to display interactive video on the iPhone. It will only be used on iPhones when an interactive timeline is present.

2.0 | Audio Assets

2.1 | MP3

This is the only asset type that will be encoded for audio media clips, and offers broad compatibility of devices and browsers. Depending on your setup we can add versions with different bitrate settings.

3.0 | What assets will be used?

The Blue Billywig Player determines what asset to use on a number of factors, to ensure the best viewing experience.

3.1 | Compatible Assets

First, the player determines what assets can be played on the device and browser that the user is using. The resulting list is also featured in the quality selection list in the player.

3.2 | Determining the “best” asset

Next, the player measures the current internet connection speed. The asset with highest bandwidth within the internet connection speed will be chosen. The player utilizes adaptive streaming, which allows automatic adjustment of playback quality if the available bandwith changes. This way, the user gets the best quality media with no delay or stuttering.

Note:

A user can still manually select an asset that has a higher bandwidth than the available internet connection speed, via the quality selector.

4.0 | Deleting Assets

We strongly discourage deleting assets, since this can result in an unplayable media on some devices. However, when an asset is deleted, the player will try to select one of the remaining assets. When replacing a media clip’s source file, deleted assets will again be transcoded. An accidentally deleted asset can be recovered by re-uploading the source file.

5.0 | Previewing Assets

Although the Online Video Platform allows every asset to be previewed, you may find that some assets are unplayable in the Online Video Platform depending on the device, browser and whether Flash is installed or not.
