Editing Media

Editing Media in your TechSmith Knowmia Library


Remove Parts of a Video

From the video view page, click Edit Media.

Choose between the following options:

Edit a Copy
When you choose to Edit a Copy, Knowmia duplicates the video in your Library and opens the copy in the editor. Existing quizzes and video analytics are not copied to your new version. You will be asked where the copy should be saved. Use the drop-down menu to select the location, select Copy. Once the copy is made, the editor will open.


Edit Original
When you choose to edit the original, Knowmia opens your video in the editor.
Please note: If you re-publish your original video, you will lose all captions, quizzes, and analytics associated with that video.

Once you choose from the above options, the video editor will open. Continue reading for help with the video editing controls, or Frequently Asked Questions.

Use the playback controls to play, pause, fast forward, or rewind your video as needed. You can also scrub the timelines to quickly scan your video.


When you reach a part you'd like to remove, select it by manually dragging and placing the green and red handles to set your start and end points. You can also use the convenient Set buttons to drop the green or red handle precisely at your current timeline position.

When you are satisfied with your selection, click Cut.


Knowmia marks a cut with a red line on the timeline, which you can later reopen any cut if you need to restore the original or adjust the start and end points.

- To restore the clip, click the red line to reopen the cut, and click Delete.
- To adjust the edit, click the red line to reopen the cut, click Edit, then reposition the handles. Click Update Cut to save your changes.

The video editor will continue to show all previous cuts, even after you publish, so that you can continue to adjust or delete them in later editing sessions.

When you’re finished editing your video, click Publish to commit your changes. 


A new version of your video will begin processing, and should be ready soon.
