If you’ve landed here, we don’t need to convince you of the performance power of Connected TV (CTV). But here are a few facts in case you need a refresher: 

  • According to MNTN Research, CTV ad spending is projected to reach $32.57 billion in 2025, nearly double its 2021 levels.
  • MNTN Research also reported on a recent study showing that 24% of advertisers anticipate strong growth for CTV, streaming, and OTT video channels in 2025, with another 51% predicting moderate growth.
  • You can pair CTV ads with streaming content that appeals to the viewer, drilling down to their location, age, interests, and other demographics to create ads that resonate with your target audience.

But you might not know all of the hyper-specific technical specifications your video ads need. Each CTV platform has different ad specs advertisers are required to use for their content. Since this information can be legitimately hard to find (seriously: why do they make it so hard to find?), we’ve compiled, by platform, every single CTV video ad tech spec you need in one easy-to-use guide.

Consider your days conducting incredibly creative Google searches a thing of the past. If you plan on placing your next video marketing campaign on the leading CTV platforms, then it’s time to bookmark this page. 

Hulu

With over 52 million paid subscribers in the U.S., Hulu is one of the leading premium streaming services in the country. What sets Hulu apart from other CTV platforms is that it offers its subscribers not only a library of original content but also next-day access to current shows from almost every major U.S. broadcast network. Hulu offers a video commercial ad package you can use to place your ad into their long-form content.

Video Specs for CTV Advertising on Hulu

  • Aspect ratio: 16:9 or 4:3, depending on the format 
  • Max file size: 10 GB 
  • Video length: Normal video creative must be either 15 or 30 seconds, while extended video creative can be three minutes or less
  • Frame rate: 29.97 or 30 fps, depending on the format
  • Bitrate: 15 – 30 MPbs for high-definition ads; greater than 2 Mbps for standard ads 
  • File type: .mov or .mp4

CTV Ad Creative Tips for Hulu: Utilize an Engaging Hook

Use the first 3 to 5 seconds of your ad to hook the viewers through dynamic motion graphics, unique aural experiences, or top-line value props. This is especially true for 15-second content, as this can increase engagement by 12x. Plus, if you can cater or nod to a streaming viewer, the better. 

For example, you can include mentioning things like watching your favorite shows back to back or not wanting to use products that aren’t at your fingertips. Other tips to keep in mind:

  • Make sure the ad can creatively begin and end with the brand name or logo.
  • Put your brand front and center. In 2020, 63% of top-performing campaigns from emerging brands on Hulu had the first branding moment immediately at the beginning of the ad.
  • On-screen text that corresponds to spoken word (VO or Dialogue) performs well, driving home messaging and branding.

Roku

A pioneer of streaming to television, Roku has emerged as a leading global CTV platform, with millions of consumers in North America, Latin America, and parts of Europe. This platform unlocks a massive and highly engaged consumer audience that any brand can reach. With advertising tools built for streaming, Roku can deliver brands relevant audiences and measurable results. Placing ads on Roku lets you reach more users and personalize your ads to speak to your desired target audience. According to Statista, the platform has over 85.5 million viewers in the U.S. alone, creating an incredible opportunity for advertisers to reach their audience.

Tubi

Tubi has over 250,000 movies and TV episodes, in addition to more than 250 live channels, providing the audience with a massive amount of content. And it’s worked — the platform has attracted a user base of over 97 million monthly active users around the globe.

You can complement your ad’s visual effects and narrative with sound effects, dialogue, or a voiceover. 

Peacock

NBC created Peacock as a way to offer current shows and its back catalog to customers. According to Business Insider, “Peacock Premium and Premium Plus plans both feature more than 80,000 hours worth of on-demand TV and movies.” And thanks to this wide inventory of content, the number of viewers continues to increase.

  • Ensure your ads fit the technical requirements. For example, you cannot stitch two shorter ads together to create a longer video. 

When you’re planning your video production, make sure you craft a variety of ads to run. You’ll need to rotate your ads regularly to combat ad fatigue. 

Amazon

Prime Video Ads through Amazon allow brands to advertise in front of nearly one hundred million U.S. consumers. According to EMARKETER, when Amazon Prime launched its ad-supported tier in 2024, 97.2 million households were using the video service in the U.S.

With that in mind, all marketing efforts should be planned to revolve around a particular target. CTV is a performance marketing platform that allows you to reach your core audience. Make this advantage work for you by:

  • Emphasizing scripts for each customer persona.
  • Casting talent that’s relatable to your audience.
  • Underlining your unique value propositions.

Sling

Although Sling TV has been around since 2015, it is becoming more popular because it offers a hybrid model of traditional live TV and on-demand streaming. People can tune into their favorite local news and live sports channels while also binge-watching their shows later. The company has over 2 million subscribers in the United States.

Whether you’re looking to create brand awareness or conversions, you must always keep the door open to new customers by introducing them to your core values and offerings. Use a different creative approach than the one you’re already implementing on your social media video marketing campaign and other higher-funnel performance marketing platforms.

Netflix

One of the most recent brands to join this list, Netflix released its first ad-supported tiers on 2022 in the U.S. After launching its streaming service in 2007, the platform was ad-free for 15 years. This change, however, has opened up new doors for advertisers and viewers alike.

CTV Advertising Creative Tips for Netflix: Focus on Quality

Paramount+

Another streaming service offered by a major network, Paramount+ began as CBS All Access. This service offers a variety of existing and original content with over 30,000 episodes of programming. Paramount+ also offers access to local CBS affiliate networks and live sports with a premium membership. Launched on June 7th, 2021, Paramount+ expanded their offerings to include a more budget-friendly, ad-supported option.

As streaming platforms go, Paramount+ offers one of the more robust advertising packages. In this platform, you can use 3rd Party VAST ads as long as they‘re in HD at a 16:9 ratio. The company requires certain items in each VAST tag, so run this sheet by your provider before sending files over.

CTV Advertising Creative Tips for Paramount+: Implement a Clear CTA

Even if your goal is purely awareness, you want to always ensure you’re paving a clear path for a consumer’s journey with your brand. Employing a straightforward CTA that gives the audience a next step encourages immediate action.

We’re all multitaskers today, and the majority of people watching streaming content do so with a digital device in hand or nearby. Consider keeping your logo and URL present throughout your video ad to tap into the channel’s direct-response capabilities.

A CTV-specific CTA can also help with attribution when it comes to measuring performance. Create a new landing page to pair with your creative and drive traffic with an easy-to-remember URL or coupon code.

YouTube

That’s right, your favorite social platform for chill lo-fi beats to study to now has hundreds of free movies and television series that are (you guessed it!) 100% ad-supported. What does this mean? You can now say YouTube in the same breath as Tubi or any number of the other AVOD services out there in the market today.

Video Specs for CTV Advertising on YouTube

  • Aspect ratio: 16:9 (best quality for CTV, but they also support 4:3)
  • Video length: Skippable ads must be at least 12 seconds, but there is no maximum length. YouTube states video ads 3 minutes or less perform best. Non-skippable ads can be 15 or 20 seconds in length, depending on regional standards.
  • Frame rate: 60fps
  • File type: .mp4, .mov, .mpeg, .avi, or .asf

CTV Advertising Creative Tips for YouTube: Branding, Branding, Branding

When it comes to the presence of branding, the YouTube landscape is aligned with that of other social platforms like Facebook. To drive views, you’ll need to incorporate branding. Aim to show your product or brand logo within the first couple of seconds of your video ad. Our analysis found that audio mentions of brands by on-screen talent also perform higher than mentions by off-screen talent.

CTV Advertising Creative Tips for Performance TV: Explore Different Styles

The streaming environment can host a wide variety of video styles, including live-action, animation, stop-motion, and post-production repurposing. Speaking of, there are two paths you can take with your CTV creative:

  • Original Production
    • The live-action approach is a great way to create talent-centric videos and bring your product or service to life. With animation, you can unlock any aesthetic that feels right for your brand.
  • Post-Production Repurposing
    • A post-production approach is often the most cost-effective way to generate CTV creative. Using motion graphics and editing techniques, you can animate and repurpose existing assets into a narrative with any message.

Whichever stylistic approach you adopt, be sure to captivate from the start, paint a clear narrative, and adopt a visual identity that feels aligned with your brand.
