Best Practices

Preferred Uploading Environment

The video player in CLAS is compatible with all major browsers (Firefox, Chrome, IE, Safari) on all major desktop (Mac, Windows) and mobile (iOS, Android, Blackberry) hardware platforms. While it is recommended that users access CLAS through the latest version of Google Chrome as it minimizes the possibility of encountering errors when both viewing and uploading content. CLAS can be used regardless whether the user has Flash installed or not.
For the fastest upload, we recommend uploading from UBC Campus Wi-Fi or Ethernet connection.

Preferred Video Resolution

Preferred resolution:

  • For instances requiring self-submission from users (ex. Music Admission), or uploading from abroad: 360p (Youtube’s default) or 480p.
  • For uploading from a strong internet connection, such as UBC Campus Wi-Fi or Ethernet Connection: 480p or 720p.
In production, adequate lighting and camera focus are far more important than the capture resolution in yielding good visuals. A slightly lower resolution video with sufficient lighting will produce a good quality video that requires less uploading time.

Preferred Video Format

The following video and audio formats are supported by CLAS to date: 3GP, AVI, FLAC, FLV, M4V, MKV, MOV, MP3, MP4, MPEG, MPG, OGG, WAV, WEBM, WMA, WMV…
MP4 is recommended for videos.

Preferred Duration

CLAS allows for up to 2GB per upload or recording (roughly 1.5h video at 480p). A video of that size would require an extended uploading time, so we recommend sectioning the video into 2 or 3 videos of 20-45 minutes each to reduce upload time.

Common Issues

  • It is possible for the sleep function on your uploading device to interrupt the uploading process, so remember to turn it off beforehand. A fast internet connection is very important for a smooth upload.
  • Occasionally after accessing an embedded version of CLAS in a Canvas page , upon returning the web version of CLAS the left-hand side menu will disappear. After clearing your browser cache and refreshing the page, the menu should re-appear.
  • PDF files that have any special symbols in their names, including ampersands, are not able to be shared to other playlists/groups/etc. It is best refrain from the use of special symbols in general when naming files in CLAS. The solution to this error is by renaming the file and re-uploading it to CLAS.
