How to edit uploaded videos on Kaltura
Editing of videos is not just limited to CaptureSpace. Kaltura features an easy to use suite of editing tools available from within your web browser. This allows you to trim, chop, add captions, set a thumbnail and add chapters.
1. Navigate to the My Media space by going via the drop down box in the right corner under your name and then clicking My Media
2. In the My Media space, you will see all your already uploaded content. To the right of each video will be an Edit button. Clicking this will open the edit page for that video.
3. The default tab in the editing page is the Details tab. This is where you can update the Name, give the video a Description and add and remove tags for easier organisation and searching of video's.
4. The Collaboration tab will allow you to transfer ownership of the video to another staff member or add them as a collaborator, enabling both of you to edit the video.
5. The Captions tab allows you to upload a file with a subtitles for your video, improving the accessibility of your resource.
5.1. The file format for captions/subtitles is a .srt file. This file has a specific format that must be adhered to.
The first line of the file is the sequence number. Each caption that is displayed on screen will have its own sequence number. The next line is the time code, this follows the format Hours:Minutes:Seconds,milliseconds. The first time code is the time the caption should start being displayed, the second is the time the caption should stop being displayed. These are separated by a double dash arrow (-->). Be careful that the text program you use does not change these to a different style of arrow.
Below the time code is the Caption Text, you can have two lines of text but try to have a max of four words per line. Too many words can be difficult to read on screen and within in the allotted time.
A blank space is required to separate the different caption sequences.
6. The Timeline tab allows you to add chapters to the video for easier navigation. Click the Bookmark icon to the left of the timeline. This will display chapter options below. From here you can use the Time and Tags option to refine the start time of the chapter. The Chapter Information settings are where you add the title of the chapter. A description can also be added.
7. The Trim Video tab gives you the ability to change the start and finish time of the video. If, for instance, you have 10 seconds at the start of the video where the speaker is getting ready and this is not of any value to students, the trim function can be used to remove the beginning 10 seconds. The video will then start at this newly specified time.
8. The Create Clip button allows you to, for example, create a 2-minute intro video to a recorded lecture or to divide the lecture recording up into smaller topic section videos while keeping the original.
Note: This function requires Flash. Please ensure that you have enabled flash in the browser.
8.1 With Flash enabled you will see a timeline appear under the video. There are a few different ways in which you can create a clip. The First way is to use the Set Starting Point and Set Ending Point buttons. As the video plays, when it reaches the point where you would like the start of the clip to begin, click the Set Starting Point button. You will notice that the grey bar in the timeline will get shorter. You can do the same with the Set Ending Point button. The second way to set the start and endpoint of the clip is to use the end markers of the grey bar in the time line. Sliding these to the left and right will control the length and start/end time of the clip
