Asset Factory

Note: The Asset Factory (automatic transcoding) needs to be enabled for your account. Contact your Account Manager if you want to use this feature.

Uploading a source video file to Pulse, or fetching it from a URL, triggers the Asset Factory automatic transcoding and generates video assets that work on any device you wish to target.

Upload video file

The Asset Factory generates all required versions of the asset file and ensures that the right file is always served to the right device. The source file can be of almost any file format and quality, however, you should try uploading a high-­resolution file with no or little compression, as the quality of the generated assets depends on the quality of the file you upload.
Note: The maximum size for uploaded files is 500 MB. Files bigger than that can be added to the Asset Factory using FTP.

The assets are transcoded and generated asynchronously, meaning you can complete your campaign booking while the video files are being created. The campaign goes live as soon as the files are ready (or when the campaign is configured to go live). If a campaign needs to target a new device, just add it to the targeting options and the Asset Factory generates a transcoded file that works for that device.

The Asset Factory enables you to:
  • see all the uploaded files, in list view (default) or thumbnail view,
  • search for uploaded files by name,
  • see all the files being transcoded, as well as their transcoding status,
  • reuse files for another ad (the Select from asset factory option when adding a new ad),
  • preview uploaded video files,
  • visit the campaigns associated with the files,
  • download source files,
  • download transcoded files (a package of all the generated assets),
  • and delete the files that are not currently used in any campaign.

General Recommendations for Automatic Transcoding

Note: These are recommendations only. Ooyala supports a wide range of source file configurations.
Encoding Setting High Definiton (HD) Specification Standard Definition (SD) Specification
Container format MP4 MP4
Video codec H.264 Baseline H.264 Baseline
Audio codec AAC-LC AAC-LC
Minimum bitrate 5000 kbps 2000 kbps
Resolution width 1280 1024
Resolution height 720 576
Video frame rate Constant frame rate, no higher than 25 fps or 30 fps, depending on the region:
  • 29.97 fps, commonly referred to as 30 fps, for NTSC countries
  • 25 fps for PAL countries
  • 23.976 fps, commonly referred to as 24 fps, for film-look content (24p)
CAUTION:
Frame rates higher than 30 fps, or where the frame rate varies across the duration of the video, are likely to cause playback failure.

Parts of the Asset Factory

Part Name Description
1 Search asset Start typing to search for an asset based on its name. Searches are not case sensitive.
2 Select view Choose between thumbnail view and list view. The functionality and information in both views is the same, just presented in a different way. By default, the asset factory opens up in list view.
3 Asset library A list of all asset files ordered by time of upload, with most recent assets at the top. The following information is available:
  • Name: asset file name and type. Click on the asset file name to view the Asset details, which provides you with asset metadata, as well the option to preview the uploaded video file, visit the associated campaigns, and download source files and transcoded files.
    Asset details
    Note: For files that are not used in any campaigns, a three dots icon (Delete asset icon) is visible in the upper right corner of the Asset details view allowing you to delete the asset file.
  • Added: the time of file upload.
  • Status: the transcoding status of a file. The following statuses can occur:
    • In Progress: the video file is being transcoded.
    • Transcoded: the video file was transcoded successfully, no errors detected.
    • Failed: some errors occured during video file transcoding, causing it to fail. Most common reasons for transcoding to fail are network issues and invalid URLs for fetching the file. You need to upload the video file again to re-trigger the transcoding process. This adds the asset file to the asset library again and automatically unlinks the failed version of the asset from the campaign, allowing you to delete it.
    • N/A: unable to perform transcoding, most commonly because the file is not a video, or it could not be fetched from URL.
  • Duration: the duration of video files.
  • Campaigns: the number of campaigns where a file is used.
Note: Complete asset information is available only for transcoded video files. Other assets, such as images and flash files, or assets whose status is Failed or N/A, are missing metadata information and the ability to preview the file.

FTP Account for Asset Uploading

Pulse allows external FTP access (for accounts defined by you) to upload assets to your Asset Factory. Anyone with access granted by Ooyala staff can upload files. The access is limited to uploading only to maintain a high security level. For information on your FTP account details, refer to Integration Information.
