# In-Stream: How to create an In-Stream campaign
Video ads have become an important agent in bringing profitable traffic to our advertisers. If you are planning to start a campaign and you don't know what format to use, we strongly recommend you to give Video a try. We explain the many advantages of Video ads in [our blog](https://www.exoclick.com/using-video-ads-to-drive-sales-for-your-online-store/).
While there are different options for Video Ads, **In-stream** is the one most favoured by our publishers and the one which will give you access to the greatest inventory. In this tutorial, we will explain how to create an In-Stream campaign.
## How to create an In-Stream campaign
In Step 1 of your campaign set up, select **Video** as your ad format. In-Stream is a **Zone type**, meaning that all Video campaigns will be targeting In-Stream by default.
If you want to target In-Stream **exclusively**, then you need to de-select the other push formats in the Zone type section:
We actually recommend you to try **targeting In-Stream only**. The main difference between In-Stream and the other video format is that it is served in the video player on the site (usually as Pre-Roll), so it has more playback capabilities. This allows you to serve high-quality video materials and experiment with different video lengths, call to actions, etc.
Then, in Step 2, create your variations. You can either **upload the video material from your device** or **link to an external video**:
You can find the tech requirements for In-Stream materials in [our ad format page](/exoclick-docs/ad-formats.md#in-stream-video-vast)
***
If you want to use a **VAST tag** as variation, you will need to ask for permission to your account manager or to our [Customer Success team](https://www.exoclick.com/contact/).

In-stream campaigns can run in CPC, CPM and **CPV**, which is a payment model exclusive to video formats. CPV stands for Cost per View, meaning that you will pay for each view the ad format generates (a view is generated after **10 seconds** of video ad playback).
The rest of the settings are chosen similarly to what you would do with any other campaign. You can find a detailed explanation of each of our targeting settings in the [main advertiser section from this documentation](/advertisers/campaigns/creating-a-campaign/create-campaign-step1.md)
