Overview
Kaltura allows users to replace the video source behind an entry. This allows you to preserve all of the original entry's metadata (title, description, tags, etc.). This can be particularly handy if you've embedded the video on a web page somewhere, since replacing the video will prevent you from having to re-embed it.
These instructions apply to all Kaltura users at UCSD with active directory credentials (instructors, students, staff, etc.).
Videos can be replaced in Canvas as well as in MediaSpace.
Critical Concepts
It may take a bit. Your replacement video may not be available for viewing immediately after replacement, as Kaltura analyzes and transcodes the new video file.
- Until the replacement video has been processed, your old video will still play. In some ways it kind of looks like nothing is happening after you replace your video. Once the replacement video is done processing on the back end, your video will switch to the new version. One way you can tell if the video is still processing is to visit the "edit page" (where you can edit all the stuff about your entry). In a gray box next to the video, you'll see "Replacement in progress" for the "media asset update date."
- Be sure to wait until the replacement video has finished uploading, so you can click "Approve Replacement." When you elect to upload a replacement to a Kaltura entry, there's an additional step you have to take, namely to click "approve replacement." So don't just leave the page after you've finished uploading your replacement.
- Replacing a Kaltura video does not initiate a new request for machine captions. So consider whether your captions need to be updated based on the new file you've uploaded. If you've made significant changes to the timing or content of the video, your captions will no longer be accurate. If this is the case, you'll either need to edit the captions yourself, or you can request new machine captions.Check out these knowledge base articles if needed:
- You can replace any media type, but you have to replace it with the same type of media as the original. So you can replace an audio-only entry with another audio file, but you can't, say, that audio entry with a video file. We've written the instructions assuming you're trying to replace a video, but the process is basically the same for all media types.
Steps to Take
Whether you're in Canvas or MediaSpace, you'll need to get to "My Media."

- Click Replace Media under the video preview.
- Click Choose a file to upload.
Select the video on your computer that you want to upload.
- Wait for the upload to complete, then click Approve Replacement. You'll see a message at the bottom of the screen that indicates that your media is being processed.
Your original video will still be viewable until the back-end processing of your replacement is complete. Remember that new machine captions aren't requested when you replace a Kaltura media entry, so you may need to consider whether your captions are still accurate.
