How Video Ads Work
Video ads (formerly in-stream video ads) can run in video players appearing on YouTube watch pages and channel pages with featured videos. These ads may run on YouTube desktop, mobile web and apps, connected TV, and game console properties, as well as the Google Video network and embedded YouTube players. Video ads may be skippable or non-skippable. Skippable video ads can be a maximum of 60 seconds and non-skippable video ads can be a maximum of 15 seconds (20 seconds in EMEA, India, Malaysia, and Singapore). Non-skippable video ads that are up to 30-seconds long are allowed on a sub-set of inventory. We also allow 5 second bumper video ads as part of sponsorship packages.
The video ad can appear when a user initiates video play either in the beginning (pre-roll), at points in between (mid-roll), or after (post-roll).
A view of a skippable ad will increment the YouTube view count at the 30 seconds mark or when the ad has been watched completely. Non-skippable ads do not increment the view count.
You can create non-skippable 15-second or 20-second video ads through AdWords. To create 30-second, standard video ads or 60-second skippable video ads, contact your customer service representative.
Keep in mind
Companion banners are optional and can be omitted from video ads. If you choose to include companion banners, be aware that that they’ll display only in the context of a watch page on YouTube. They do not appear on mobile devices, embedded players, connected TVs, or on game consoles.

Companion Display Ad - Optional
Companion banners are optional and can be omitted from video ads. If you choose to include companion banners, be aware that they’ll display only in certain cases, for example, if the banners are viewed in the context of a watch page on YouTube. They do not appear on mobile devices, embedded players, connected TVs, or on game consoles.
- YouTube is aware of ad delivery issues with some companion units (300x250s & 300x60s) due to the nature of how VAST is requested and rendered by the IMA SDK. As a result, companion banners may not always appear. Please note that the unit itself is not billed upon and not guaranteed. We are working to resolve these issues as soon as possible.
Companion banners can be site-served, third-party served or VAST-served. For the full list of specs please visit this page. If a companion ad is not provided, no other advertiser's ad will appear next to your video ads.
In some cases, if a companion creative is not supplied and the ad is a public YouTube hosted video, a companion will be automatically generated which includes information about the channel hosting the video ad. The automatically generated companion links to the channel, and will include the channel icon and name, and thumbnails of up to 5 videos from the most recently updated playlist on that channel.
