About Video Streaming Services

A convenient way to deliver videos online is by video streaming. Streaming means that the video is sent in a continuous stream of data and the video starts to play as the stream of data (i.e. part of the video only) arrives the user's computer. Currently, video streaming services are provided to staff. Students are suggested to use Google Docs with their student email accounts to save and share videos.


Use YouTube for public video

YouTube is one of the best video streaming services that has servers around the world. It also provides the transcription/subtitle function, supports multiple bit rates and most importantly, is accessible on most mobile devices. However, videos on YouTube are stored in a public domain and are searchable online. Internal or confidential videos should not be shared through YouTube.


Video Streaming Services (for Staff Only)

  • OCIO provides video streaming services for staff so they can publish videos (e.g. pre-recorded lecture or speech) on the Internet.
  • The streaming services are provided solely for the purpose of the University and are not intended for personal use.
  • Currently, video formats supported are MPEG-4 Video format (.mp4) and MPEG-3 Audio format (.mp3). Users are suggested to encode new videos to mp4 (H.264) format.
  • The default quota for the file size is 1GB, and the maximum bandwidth per video stream is 1Mbps.
  • The quality of video depends on bit rate but it affects the video size. For instance, a one-hour video file at bit rate of 1Mbps (320 x 240 pixels) is about 450MB.
  • For copyrighted materials, users should ensure that they have obtained relevant permission from the copyright owner before publishing the content.

How to use the Video Streaming Services?

  • To use the services, staff should apply for a video streaming account by completing the Video Streaming Account Application Form (F019) which can be obtained at ocio/forms.
  • Encode the video file in mp4 format.
  • Upload the converted video to the assigned directory of the streaming server. For example, if the directory is \\email.ied.edu.hk\fms\media\account-directory, the user should open a File Explorer window and type this directory in the address bar. Then, copy or drag the file to the assigned directory. Due to firewall settings, users have to upload the video on campus. (Note: Chinese characters are not supported in the file name.)

  • To publish the video, users can use the URL Generating Tool (see below) to create a http link where the video can be accessed directly.

More details on the assigned directory and instructions will be sent to the user individually after the streaming account is created. Please see below information on file format.


 MPEG 4 (H.264)

  • Users are recommended to use mp4 video format, which is more portable. It can be played on both PCs and Macs. For portable devices, mp4 videos can be played on most Android and iOS systems.
  • There are many software packages available in the market that convert videos to mp4 format. One of which is “Any Video Converter Free”. Most of the video camcorders also support mp4 (H.264).
  • mp4 (H.264) videos can only be published through a webpage. To facilitate this, OCIO has developed the URL Generating Tool to generate URLs for accessing the video on a web browser. To publish your video, users can simply send the URL generated by the tool to the target audience.
