Whenever you place a mid-roll ad break marker (the orange markers in the screenshot below), Omny automatically generates a tag which can be targeted in the Omny Campaign Manager, or in TAP. These auto-generated tags use the following format: midroll_pos_n, where n represents the mid-roll ad break position.

Here's an example of an episode with multiple markers: 

The second ad break marker uses the auto-generated tag midroll_pos_2.

Negative offsets are also supported, e.g. midroll_pos_-2 for the second last mid-roll marker.

Ascending format:

First mid-roll marker = midroll_pos_1
Second mid-roll marker = midroll_pos_2

And so on...

Descending format (valid for clips published after 2021-04-30) - please contact support if you'd like to apply descending order to older clips

Last mid-roll marker = midroll_pos_-1

Second last mid-roll marker = midroll_pos_-2

And so on...

If you are a TAP user, please refer to the TAP user guide.

If you'd like to target the 2nd mid-roll ad marker in this example (the one which the red arrow is pointing to in the screenshot above) then simply type midroll_pos_2 in the tag targeting rules input when configuring your flight here:

Please note that a flight targeted to a mid-roll marker with no tag specified is eligible to be inserted at a tagged mid-roll marker.

A flight which is targeted to a specific tag can only be inserted at those tagged markers.
