Check your video against common CTV delivery specs and the ATSC A/85 loudness recommendation in seconds. We read the resolution, frame rate, codecs and bitrates, and measure loudness and true peak. Then switch between major streaming platforms to see if your ad meets each one’s spec. Your file is analyzed on your computer and never uploaded.

A summary, not legal advice
This tool measures your ad against -24 LKFS. It can't compare your ad with the program it will run next to, and each streaming service decides how it meets its own obligations.
The video ad delivery specs of major streaming platforms, as each one publishes them (Q4 2026). They aren’t updated automatically, so confirm the current spec with the platform before you deliver.

Most streaming platforms ask for a 1920 × 1080, 16:9 file at its native frame rate (29.97, 23.976 or 25 fps), progressive and constant. The video should be Apple ProRes 422 HQ or high-bitrate H.264, with stereo 48 kHz audio at about -24 LKFS and a true peak below -2 dBTP. The file should be cut to an exact spot length, with no bars, slate or tone. Each platform adds its own rules on top, which is what the checker compares.
Yes. Every platform on this page accepts an MP4 with H.264 video and AAC audio, and Amazon Ads, Samsung Ads and VIZIO take MP4 only. Several platforms, including NBCUniversal, Netflix, Roku and Hulu, also accept or prefer Apple ProRes in a MOV file as a higher-quality master. Use AAC at 192 kbps or more to meet most audio specs.
There's no single number. At 1080p, H.264 at 15 to 30 Mbps meets the minimums of most platforms here (Amazon's Prime Video asks for at least 15 Mbps), but Samsung Ads caps hosted video at 10 Mbps and VIZIO at 12 Mbps, so those need their own export. ProRes masters are far larger by design. The checker's file-weight tip flags files that are too light for a big screen or heavier than they need to be.
The common reference is ATSC A/85: an integrated loudness of -24 LKFS, with a tolerance of about 2 dB, and a true peak below -2 dBTP. Some platforms differ: FOX asks for -28 to -24 LKFS, VIZIO for -23, and Paramount for a peak below -6 dB. Streaming services often play everything at one level between -23 and -27 LKFS, so aim for -24 or a little below.
1920 × 1080 at 16:9 is the safe choice: every platform on this page accepts it. Deliver at your native frame rate, usually 29.97, 23.976 or 25 fps, constant and progressive, with no frame-rate conversion. Some platforms accept more, such as 4K and up to 60 fps on Netflix, and Samsung Ads and VIZIO list 30 fps.
:15 and :30 spots are accepted almost everywhere. Lengths such as :06, :45, :60 and longer vary by platform and by placement (pre-roll or mid-roll). Each platform's card above lists its accepted lengths.
No. The checker reads your file and measures its loudness inside your web browser. The video never leaves your computer and is never sent to ADTE.
According to the FCC, its CALM Act rules apply to TV stations, cable and satellite, not to ads on the internet or in streaming. In California, SB 576 says that from July 1, 2026, a streaming service serving California residents must not play ads louder than the content they accompany. That law applies to the streaming service. This is a summary, not legal advice.
The platform specs are taken from each platform's publicly available specifications as of Q4 2026 and are not updated automatically. Platforms change their specs, and the spec for your buy may differ, so always confirm with the platform or your account team before delivery.

Results are automated estimates. They are based on the metadata in your file and on an approximation of the ITU-R BS.1770 loudness measurement, run in your web browser. They may differ from certified loudness meters, from the measurements of any platform, publisher, broadcaster or streaming service, and from your file after it is transcoded. A result that meets the spec does not mean that any platform will accept your ad, or that your ad complies with any law or regulation, including the CALM Act, the FCC’s rules or California’s SB 576.
The specifications shown are recommendations. Each platform sets its own delivery requirements, and where a platform provides its own spec, that spec governs.

They are not updated automatically, may be incomplete, and may not reflect the spec that applies to your buy.
