Working with Video (Kaltura, Canvas, Zoom, and PowerPoint)

34 Editing your video

There are times when you record a video and you’re mostly satisfied with it but you need to do some minor editing. There are several ways to accomplish this depending on what you want to do and what type of computer you are using.

NOTE: If you are using any video editor application on your computer (Win10 Video Editor, QuickTime, iMovie, or Adobe Rush) your video must be on your computer. If you record using Zoom, you’ll want to record to  your computer instead of recording to the cloud. If your video is already in Kaltura, you can download your video.

The following sections address video editing in

Using Kaltura

No matter what type of computer you are using, you can do some very basic editing in Kaltura: My Media in Canvas or in Kaltura Mediaspace. The options include trimming the beginning, trimming the end, and cutting out pieces in the middle. You cannot use the Kaltura editor to combine separate videos into one video.

There are two very important things to know about using the Kaltura video editor before you start editing.

  1. You need to edit your video before you edit your captions. If you edit captions first and then edit the video, the caption timings will be wrong. If a caption file has already appeared on a video you are going to edit, save the edited video as a copy to automatically get a new, properly timed caption file that you can edit.
  2. Also note that when you are saving your edited video, whether saving or saving as a copy, it can take 2-4x the time of the video to save. If you close that tab or window where it’s saving, it will stop saving and you’ll lose your edits.  You can go do other things while it’s saving as long as you don’t actually close the tab/window.

The following video walks you through using the Kaltura video editor.

Using the Built-in Windows 10 Video Editor

If you are using a computer running Windows 10, there is a basic video editor built in to the Photos app. Type “video editor” in the Windows search box to open it. There you can create a new project and add your existing video. Tools in the video editor allow you to

  • trim and cut video
  • splice multiple videos together
  • speed video segments up or slow them down
  • add text on top of or next to the video
  • insert a title slide
  • and more

See the following video for a walk-through of how to use the Photos app video editor.

Using QuickTime or iMovie

NOTE: If you are using any video editor on your computer (Rush, Win10 Video Editor, QuickTime, or iMovie) your video must be on your computer. If you record using Zoom, you’ll want to record to  your computer instead of recording to the cloud. If your video is already in Kaltura, you can download your video.

If you are using a Mac, you have two native application for video editing.

QuickTime allows you to split a video into smaller clips, trim videos, and splice videos/clips together.  You can find instructions for using QuickTime from Apple. and the following video walks you through basic trimming and cutting out parts of a video.

If you want to do more editing such as adding titles, transitions, etc., you will likely want to use iMovie. You can find iMovie instructions from Apple. There are also a large number of video tutorials available at YouTube.

Using Adobe Rush

Note that Adobe Rush is only functional for short videos. If your video is over 8 minutes long, use a different editing tool.

If you are on a Mac or Windows computer, you can download and use Adobe Premiere Rush from Adobe@IU.  Rush is a user-friendly editing tool that allows you to do additional edits such as combining multiple video segments, adding text on a video, or adjusting the volume of the narration. You will need to download the Adobe Creative Cloud to install Rush on your Mac or Windows computer. Please be patient as it will take some time to download and install Creative Cloud and then to download and install Rush. 

To use Rush, you need to have the video (or videos) you are editing on your computer. Where your video is, depends on how you recorded it. If you record using Zoom and choose “record on this computer,” when you end your meeting Zoom will pop up a window letting you know your file is processing, and then it will open the folder showing your video file. You want the mp4 file, not the mp3 or m4u files, to edit.

If you recorded using PowerPoint or Keynote,  you will have chosen where to save your video file so you can easily find it.

If you recorded using Kaltura Personal Capture, your video is still on your computer as well but it is not as easy to find as it is when you record with other tools. To find a video recorded with Personal Capture, search for the video file on your computer using File Explorer on Windows or Finder on Mac. Kaltura does not name the files in a meaningful way so you will want to identify your video by the time/day when it was recorded. Here is an example of what the Kaltura files look like on a Windows computer.

The UITS Support Center can assist you in finding your videos if you have difficulty.
