A list of all the supported file formats is available here


A copy of the uploaded file is stored as-is and labelled as MASTER. This file will be re-used to create new and additional video formats in the future as streaming technologies evolve.

Based on the bitrate of the uploaded media file, additional media formats(low, medium and high) are created to serve users who may be on different bandwidth or Internet speeds.

The media format of these presentation streams for videos is MPEG-4 (H.264 video + AAC audio) and for audio files it is M4A (DOLBY AAC)


Uploading from your computer/device versus uploading through a FTP or HTTP server
· Users  coming from browsers  that support HTML 5 (Note: Internet Explorer 9 does not support HTML 5) can upload content up to 5 GB  from their personal devices
· If the file size is greater than 5 GB, users must upload the files from a FTP server, HTTP (Webserver) or Dropbox and specify the path to the file in the upload screens

A note about large file uploads and user bandwidth

Please note that depending on the users internet network large files may take longer to upload and in cases where the user might not have sufficient bandwidth, the upload process may stall and file upload may fail.   


Recommended specifications

In order to get the best viewing experience for the users, it is a best practice to upload the highest quality (or bitrate) media file


For video:


Video: Codec: MPEG-4, H.264, Bitrate: around 3-4 Mbps or less

Audio: Codec: AAC, Bitrate: about  128Kbps - 192Kbps
....or choose 720p export/share format in iMovie. (1080p can also be chosen if the total file size is < 3GB)
If your video is in a format other than MPEG-4 (H.264) it will be converted automatically.
Once you upload a file based on the recommended specifications above, the other bitrate formats (listed in the next section) will automatically be created by the system.

For Audio:


For audio, the best practice would be to upload the highest quality (or bitrate) audio file.

FAQ:

What tools do I use to convert my video files? 
You can use Handbrake, iMovie, or other editing platforms to meet the recommended specifications.

I don't have access to a FTP/HTTP server and want to upload a large file. What do I do?
  • Using Dropbox: You can put the file in your dropbox account (www.dropbox.com) and provide the "Direct download link" in the FTP/HTTP location.  The advantage to using Dropbox is that you can share files from your workstation and copy it to the cloud and will not have to rely on your bandwidth for uploading to NJVID.
  • Other file storage services: Put the file on the remote server and provide the public URL for the video.
