Video ad specs for connected TV ads are different from the vertical specs you already know from TikTok or Reels, and the gap trips up a lot of advertisers who are used to making social-first creative. Connected TV (CTV) means ads that play inside streaming apps on a smart TV, streaming box, or games console — think a pre-roll before a show on a streaming app, running on a living-room screen instead of a phone. The underlying video format is closer to traditional broadcast TV than to mobile social video, which changes almost every technical and creative decision.
What Makes Connected TV Different From Social Video Ads
On a phone, your ad has to survive sound-off viewing, thumb-stopping in a feed, and a screen the size of a hand. On CTV, the ad plays full-screen on a television, sound is on by default, and there is no scroll, no thumb, and usually no tap-to-click. Viewers are often sitting several feet away, sometimes with a remote in hand and a second screen (phone) nearby. That changes what "readable" and "skippable" mean, and it changes what counts as a strong call to action, since most CTV inventory has no clickable link at all.
Because of this, video ad specs for connected TV ads borrow more from traditional 30-second TV commercial conventions than from mobile-first vertical video rules. If you are coming from social, treat CTV as a separate deliverable, not a resize.
Video Ad Specs for Connected TV Ads: The Core Requirements
Exact limits vary slightly by streaming app and ad server, so always confirm against the specific platform you are buying through. That said, the vast majority of CTV inventory converges on the same baseline, which is worth treating as the default to design for.
| Spec | Typical requirement for CTV |
|---|---|
| Aspect ratio | 16:9 landscape (full-screen television frame) |
| Resolution | 1920x1080 as a safe standard; some players accept 1280x720 or request 4K masters |
| Frame rate | 24, 25, or 30 fps, matching the broadcast standard of the target market |
| File format | MP4 or MOV container with H.264 encoding is the most widely accepted |
| Duration | 15 or 30 seconds are the two standard lengths; some inventory also accepts 6 or 60 seconds |
| Audio | Stereo audio track, sound on by default, no reliance on captions alone |
| Safe area | Keep key text and logos inside a central safe zone, away from the outer edge of the frame |
| Bitrate / codec | Ad servers generally ask for a high-quality, broadcast-grade master file rather than a heavily compressed web export |
If you have already built specs sheets for other formats, the pattern will feel familiar — it is the same discipline used for Google Demand Gen ads or Meta Advantage+ ads, just applied to a landscape, sound-on, link-free environment.
Technical Checklist Before You Submit a CTV Ad
Aspect ratio and safe zones
Build or export at 16:9. Keep your logo, headline, and any offer text inside a safe zone roughly 10% in from every edge, since some TV hardware and overscan settings can crop the outer margin of the frame.
Resolution and frame rate
1920x1080 is the dependable default. If your master is higher resolution, keep it — many ad servers prefer receiving a high-resolution master and downscaling themselves rather than receiving a pre-compressed low-resolution file. Match your frame rate to the broadcast standard used in your target market rather than guessing.
File format and codec
MP4 with H.264 video encoding is the most broadly compatible choice across CTV ad servers and streaming apps. Avoid exotic codecs or container formats even if your editing software defaults to them.
Audio specs
CTV audio should carry the full message on its own. Unlike mobile social, you cannot assume sound is off. Mix dialogue, music, and sound effects so the voiceover is clearly the loudest element, and avoid clipping or distortion, since TV speakers and soundbars will expose weak audio mixes quickly.
Length
Fifteen and 30 seconds are the two lengths almost every CTV buy supports. If you only have budget or time to make one version, make the 30-second cut first, then trim it down to a tighter 15-second version rather than padding a short idea out to 30 seconds.
Design Rules That Matter More Than Specs on CTV
Hitting the technical spec gets your ad accepted. These design choices are what make it actually work on a television screen:
- Lead with sound. Open with a clear spoken line or music cue in the first few seconds, since there is no muted-feed scroll to design around.
- Make text bigger than you think you need. Viewers sit farther from a TV than from a phone, so small captions or fine-print offers that work on mobile can be unreadable on a living-room screen. The same sizing logic used for recommended text size on vertical ads applies here, just scaled up further for viewing distance.
- Put your brand name on screen early and often. There is no profile name or handle next to the video like there is in a social feed, so the only branding viewers get is what you put in the frame.
- Replace the link with a QR code or a clearly spoken and written offer. Most CTV placements are not clickable, so your call to action needs to work as something a viewer can act on later: a brand name to search, a promo code to remember, or a QR code they can scan with a phone.
- End on a clean, simple end card. Hold your logo, offer, and QR code on screen for at least a couple of seconds at the end rather than cutting straight to black.
Connected TV vs Social Video Ads: What Changes in Your Creative
It helps to see the two formats side by side, since almost every assumption flips.
| Element | Social video ads (TikTok, Reels, Shorts) | Connected TV ads |
|---|---|---|
| Orientation | Vertical 9:16 | Landscape 16:9 |
| Sound | Design to work on mute | Sound on by default |
| Call to action | Tappable link or swipe-up | QR code, spoken offer, or brand recall |
| Viewing distance | Arm's length | Several feet, often with others in the room |
| Skippability | Scroll past in under a second | Usually unskippable within the ad break |
| Text size | Readable on a small screen | Needs to be larger for a big screen at distance |
How to Adapt a Social Ad for Connected TV (and Vice Versa)
Most brands do not build a CTV ad from a blank page. They adapt an existing campaign. A workable process looks like this:
- Start from your strongest landscape or square asset, not your vertical one. A 9:16 video with black bars pasted onto the sides reads as unfinished on a TV screen.
- Re-cut the pacing for a longer attention window. CTV viewers are typically not scrolling away mid-ad, so you can let a shot breathe for a beat longer than you would on a phone feed.
- Resize all on-screen text to the larger end of what still looks intentional, and move anything close to the frame edge into the safe zone.
- Replace any swipe-up or tap prompt with a QR code and a verbal call to action, since the viewer cannot click through.
- Mix the audio so the ad works with sound as the primary channel, not as a supporting track behind captions.
- Export as MP4, H.264, 1920x1080, matching the frame rate used by the ad server you are delivering to.
If you are using FrameNotion to generate your core ad from a product link, every ad is produced as a 30-second 9:16 video for feeds, and it also comes bundled as 4:5, 1:1, and 16:9 exports. The 16:9 version is a useful landscape starting point for a CTV cut — the framing and pacing already match a widescreen layout — but it still needs the CTV-specific pass above: larger text for TV viewing distance, a QR code in place of any link-based call to action, and a final encode that matches your ad server's codec and resolution requirements. FrameNotion does not publish directly to any ad platform and does not report on ad performance, so the CTV delivery and traffic steps stay with your media buying workflow.
A Pre-Flight Checklist You Can Copy
Before you upload a connected TV ad to any ad server, run through this list:
- File is 16:9 landscape, exported as MP4 with H.264 encoding
- Resolution is at least 1920x1080, frame rate matches the broadcast standard for the market
- Duration is exactly 15 or 30 seconds, with no awkward trailing silence or freeze frame
- Audio carries the core message; the mix has been checked on a TV speaker or soundbar, not just headphones
- All text and logos sit inside the safe zone, away from the outer edge of the frame
- The call to action is a QR code, a memorable offer, or a brand name to search — not a clickable link
- The end card holds the logo and offer on screen long enough to be read from across a room
- The file has been checked against the specific ad server's upload page, since limits can vary slightly by platform
For a broader look at how length requirements shift across other video placements, the guide on recommended video length for shorts ads is a useful companion piece, since the 15/30-second convention on CTV sits at the opposite end of the spectrum from short-form social cuts.
Where FrameNotion Fits
FrameNotion is built around turning a product page or a poster into a finished 30-second vertical ad in about 10 to 20 minutes, with the AI writing the script, voiceover, captions, and pacing from scratch rather than from a template. Its direct output targets feed placements — TikTok, Instagram Reels, YouTube Shorts, Facebook Reels, and Meta ads — and every ad also exports as 4:5, 1:1, and 16:9. For connected TV specifically, the 16:9 export is a reasonable base to start from rather than a finished CTV deliverable: you will still want to add a QR code in place of any clickable call to action, confirm the audio mix works on a TV speaker, and check the final file against your ad server's exact codec and resolution requirements. You can see the kind of ads it produces in the examples gallery, check how the process works, or start with the first ad free on the pricing page before deciding if a paid plan fits your workflow.
Frequently asked questions
Do connected TV ads need captions if sound is always on?+
Captions are not required the way they are for muted mobile feeds, but adding them is still good practice for accessibility and for viewers watching with the volume low. The core message, however, should be fully carried by the audio, since you cannot assume captions alone will be read on a TV screen.
Can I run the same video on connected TV and on YouTube Shorts?+
Not without changes. YouTube Shorts expects a vertical 9:16 video designed for sound-off scrolling, while connected TV expects a landscape 16:9 video designed for sound-on, full-screen, unskippable viewing. Treat them as two separate exports built from the same core idea rather than one file used twice.
What resolution should I use if I'm not sure which CTV platform will run my ad?+
1920x1080 in a 16:9 frame is the safest general-purpose choice. If you have a higher-resolution master available, keep it on file, since some ad servers prefer to receive a higher-resolution source and handle any downscaling themselves.
Does a vertical 9:16 ad ever work on connected TV?+
Generally no. Most CTV inventory expects a full landscape frame, and a vertical video with black bars added to the sides tends to look unfinished on a television screen. It is better to create or adapt a proper 16:9 cut.
Is a QR code necessary on a connected TV ad?+
It is not mandatory, but it solves a real problem: most CTV placements have no clickable link, so a QR code gives viewers an immediate way to act on their phone while the brand name and offer are still on screen.
