Edit Kaltura Media

Trim a Video

You can trim out parts of video from the Edit screen on any video. The Trimming tool allows you to edit your videos visually by setting start and end times for your media.

Trimming changes the original file, and the change is permanent.

  1. In My Media, click Edit next to the entry you want to trim.
  2. In the Edit Media screen, select Trim Video. Use the trimming timeline or enter exact start and end times.
  3. Press Play and click Set Starting Point of the video or enter the start time manually.
  4. Click Set Ending Point for the end of the video, or enter the end time manually.
  5. Click Trim Video. The newly-trimmed video will appear in your My Media.

Create a Video Clip

In Kaltura, you can create clips from existing videos; each clip becomes its own new media entry.

The clipping tool enables you to edit your videos visually or by setting the start time and end time of your clip.

  1. In My Media, click Edit next to the entry you want to use to create a clip.
  2. Click on the Actions menu and select Create Clip.
    Kaltura - Create a Clip
  3. Use the Clipping timeline or enter exact start and end times.
    Kaltura - Create a Clip - clipping timeline
  4. Press Play and click Set Starting Point of the video clip (timeline), or set Start Time manually above.
  5. Select Set Ending Point of the video clip (timeline), or set End Time manually above.
  6. Click Create Clip.

Manage Chapters and Slides

Chapters are like bookmarks, which can be used to navigate through a video. You can use chapters to mark the beginning of a new topic, highlight important segments, or help navigate through a longer video. You can add, edit and delete chapters and slides in the Timeline tab under My Media.

A Slide is a visual element synchronized to the main media. Slides can be viewed inside the player, simultaneously with the media.

After Chapters and Slides are created, the player will display the Navigation Panel: a list of chapters and slides available alongside the main video content.

Captions in Kaltura

The Kaltura platform offers the option of adding captions to any video you upload. Adding captions to videos makes them more accessible to various groups, including deaf/Deaf/hard-of-hearing people and people for whom English is a second language.

Adding captions to Kaltura videos is a 2-step process.

Step 1: Create Caption File(s)

First, you must create the caption file. Kaltura is compatible with SRT and DXFP formats.

There are several ways of creating caption files.

      • You can create the file manually and attach it to the video.
      • Some tools allow you to upload an existing transcript of the dialogue in the video and create the captions from that.
      • Still other tools (like YouTube or Camtasia) allow you to upload a video and then use audio-to-text transcription to create captions that you then edit for accuracy.

At present, Kaltura has no built-in tool for creating captions, so some other options are listed below.

Create a .srt file using YouTube’s Auto-Captioning

You will need a YouTube account to use the YouTube captioning tool.

      1. Upload the video to YouTube (we recommend uploading it as Unlisted).
      2. Once the video has been uploaded, find it in the Video Manager and select the video’s Edit button.
        Kaltura Captioning - Captions - YouTube Caption Edit Button
      3. Select “Subtitles and CC.”
        Kaltura Captioning - YouTube Captioning - Select Subtitles and CC
      4. You may see a pop-up asking you to Set video language. Select the language most often spoken in the video and click Set language. YouTube will attempt to automatically caption the video, but this does not always work. Select the English (Automatic) option to start the process.
        Kaltura Captioning - YouTube captioning tool - English (Automatic)
      5. Click on Edit above the Captions. Read through the entire set of captions to fix incorrect captions, wrong words, unneeded captions, spelling mistakes, and to adjust timings. Refer to YouTube’s official “Add subtitles & closed captions” support page for more details.

      6. Once your captions are correct, open the Actions menu and select .srt. The caption file will download to your computer.

Create a .srt File in YouTube using a Transcript

This method allows you to bypass YouTube’s auto-captioning tools and manually upload a written transcript that you previously created. This file should be in plain text format (.txt). This file type can be created in programs like Notepad or TextEdit.

      1. In the Subtitles and CC area of the Video Manager, select Add new subtitles or CC. Select English (or the language that will be used).
        Kaltura captioning - Upload transcript to YouTube
      2. Click Upload a file.
        Kaltura captioning - Youtube captioning - upload a transcript file
      3. Click Transcript. Click Choose File and locate the transcript file on your computer. Click Upload.
      4. Once the file has uploaded, click Set Timing.
      5. YouTube will begin processing the uploaded transcript and attempt to sync it to the video. When processing is done, open the captions, check that the transcript has synced correctly, and make any necessary adjustments.
      6. Download the completed caption file as above.

Step 2: Add Caption File(s) to Video

In Kaltura, you can add multiple caption files to a video from the Edit view on any video available to you in My Media. You can add multiple caption files, and captions will be searchable along with Title and tags.

      1. Click Edit next to the video you want to add captions to.
      2. Click on the Captions tab.
      3. Click Upload caption file.
        Kaltura Captioning - YouTube caption tool - upload caption file
      4. Click Browse and locate the caption file on your computer
      5. Select the caption language.
      6. Enter a label to display for the file in the caption selector (usually the language of the captions, e.g. “English”). This is what will appear in the Captions menu on the video player.
      7. Click Save to upload the file.
      8. Above the video, click on its title to leave Edit mode and view the media. The caption will now appear in the video’s Captions menu.
