You know that mixing video ad formats is a good idea, but you aren’t sure which mix is most appropriate for your goal of driving maximum reach and video completions you should use skippable in-stream ads and non-skippable in-stream ads, that is the mix of awareness ad formats.

• Masthead ads and non-skippable in-stream ads
• Skippable in-stream ads and bumper ads
• Skippable in-stream ads and non-skippable in-stream ads
• Masthead ads and bumper ads

The correct answer is: Skippable in-stream ads and non-skippable in-stream ads

Explanation: To achieve the goal of driving maximum reach and video completions, the advertiser should use a combination of skippable in-stream ads and non-skippable in-stream ads. Skippable in-stream ads can be skipped after 5 seconds by the viewer, while non-skippable in-stream ads are not able to be skipped and are usually 15 seconds or shorter. Using this mix of ad formats will help to increase both reach and video completions.
