In a Delete Challenge students are asked to either Delete or Ripple Delete a particular clip or clips (learn about creating challenges).

  • Example: Find the b-roll clip that doesn't match the voice over and delete it.

In the example shown here, a student must first:

  1. Look at the timeline for a hint about which tool to use (Delete or Ripple Delete)

  2. Select the clip they wish to remove from the timeline

  3. Press the proper delete button from the tools palette

Creating a Delete Challenge

From the lesson panel, add a challenge and choose the challenge type Delete.

NOTE: Once a challenge type is set, it cannot be changed.

Complete the required information: Challenge name, question type, description, max score, and comment for unmarked sections. Hint is optional.

  • Max Score represents the total points for the challenge, meaning all the correct answers are combined. Remember, challenges can have more than one correct answer.

  • Comment for Unmarked Sections means the message that students will see if they leave a marker on a portion of the timeline to which you did not set an answer.

Build a Timeline or Use a Template

Next, build your timeline by importing footage or select a template.

Import or use the Media Browser

Import footage into EditMentor

After importing footage, you will build a timeline in the editor. EditMentor includes editing tools like marking in-point, out-point and using insert and overwrite edit.



Templates are prebuilt timelines and library clips that you can use for lesson building.

Note: Before you can save your challenge, you must build a timeline and add at least one correct answer.

Adding Answers

When your sequence is ready, press add answers.

Select the clip that you wish to place an answer on and press Add Answer.

Example of answers on an unlinked clip

If the clip is unlinked, the answer will only pertain to audio or video.

Adding answers to an unlinked clip is useful if, for example, the student is instructed to remove a sound effect or audio of the director talking.

If the selected clip is linked, then the answer will include both video and audio.

Learn more about linking and unlinking here.

Answer added to a linked clip

Note: We will discuss linking a clip a bit further down in this article.

Once an answer is added, the Information Panel will open. You will be prompted to enter the following required information: Answer type (correct, incorrect, partially correct), the delete type (delete or ripple delete), answer score, and answer description.

Note: Students who use the incorrect type of delete will get the answer scored as incorrect.

Clips with answers on them will be highlighted in your timeline.

Once all answers are added press Stop & Save in the upper right corner of your browser.

Changing Answers

At anytime you may press add answers again from the information panel. To change an answer of a clip, double click it to open the information panel once again.

To remove an answer, select the clip and chose remove answer above it.

  • Note: The first answer applied in your timeline must be a correct answer. If you are unsure of what the answer will be, we recommend adding an answer to a random clip.

To link or unlink a clip you must be in editing mode. If you are in the mode that allows you to add answers, press Stop & Save first.

Right click (or control key and then left mouse click) on the clip that you'd like to change the link state. Depending on the clip's current link state, you will see the option to link or unlink.

Note: You may select any two clips and link them together.
