Lockup sits a bit lower here than on the :06. Worth checking which layout is approved.

Encoder profileHigh@4.0
Expected: Main Profile @ Main Level (MP@ML)
The spec asks for Main Profile @ Main Level (MP@ML). High is what most 1080p encoders emit and is generally accepted; re-export with -profile:v main if the platform pushes back.

Constant bitratenot declared in the bitstream; measures as VBR (0.0–11.2 Mbps per second, mean 6.6)
Expected: CBR encoding
Export with CBR rate control. In ffmpeg: -b:v N -minrate N -maxrate N -bufsize N -x264-params nal-hrd=cbr. In Adobe Media Encoder, set Bitrate Encoding to CBR. Without HRD parameters the file carries no CBR claim for a QC tool to read, even when the rate is steady.

Cut lands a frame late against the music here. Worth a look before this goes to the client.

Drop video files here Scored against the platforms you pick. Checking 7 platforms Choose Files

One file, every platform, and the two notes a person left on the picture.

What it checks

It reads the file once, then scores what it found against every platform you picked.

The things that get a file bounced

SpotCheck examines codec, container, resolution, frame rate, pixel aspect, audio layout and bit rate, and whether your 30 is actually a 30.

Loudness and true peak

It measures integrated loudness and true peak the way the broadcast standard does, then holds them against the numbers the platforms you picked actually publish.

It reads your slate

Five seconds of slate, a silent leader, and your ad starting on the frame the spec names (frame 168 at 23.98). Then it reads the slate on screen and checks the ad code against your file name.

Safe area, and what the app covers

Title and content safe guides are drawn over the picture from the published figures. On a vertical cut it also draws TikTok's safe zone and the zones Meta uses for Reels and Stories.

Captions, checked against picture

Drag and drop an .srt onto the picture and it plays against the video. Every track is spell checked, with each word the dictionary doesn't know listed at the timecode it appears.

Notes on the frame

Pause anywhere, draw on the picture, and write a note. It stays attached to that exact frame. Notes are keyed to the file itself, so renaming the master to its ad code does not lose them.

Every cut on one playhead

Play all the cuts of a campaign at once. Line them up by their last frame so you can compare the end cards for the 6, the 15 and the 30.

A PDF you can send

Export the verdict, your notes with the drawings still on them, and every check with what was measured. See a sample.
