Video treatments are not assigned to ads through Marpipe. Follow the steps below to allow Meta to run your product-level videos for your ad
Video treatments work differently than the traditional static treatments in Marpipe. Instead of assigning different treatments to your Meta ads you will be adjusting the settings on the ad in Meta in order for the video treatment to be automatically used instead of other media.
Your video DPA will only appear for users who Meta predicts are more likely to convert on video ads than static ads. This means not all users will see your video DPA. We recommend still assigning an image treatment to your ad even with allowing product video to display.
Here is what to do
Prerequisite: You have video DPA designs published into your video treatment and your video treatment is in an output feed that is actively connected to a Meta Catalog.
Step 1: Create an ad that is using your catalog as the creative source in Meta.
Step 2: Go to Ad Creative and make sure Allow product video is enabled. This may be enabled by default when you create a new ad
Step 3: Keep Automatic video cropping off
Step 4: Publish your ad.
Your ad will now be allowed to use your generated product videos.
If Product video is enabled on any other catalog ad you are running, your videos will appear there as well. These videos are not explicitly assigned to ads, but rather accessed via Meta's creative options
