Creative specs
One master file runs every screen. This is what to hand your production team.
Antebyte runs one video creative across connected TV, mobile in-app, and online video — and static banners on display. You upload masters once; we handle trafficking and delivery to every surface, so there are no per-placement resizes and no trafficking sheets. This page covers the video master; each channel page covers what changes on that screen.
The video master
| Aspect ratio | 16:9 |
| Resolution | 1920×1080 recommended · 1280×720 minimum · 4K accepted, delivered at up to 1080p |
| Duration | 6–30 seconds · 15s and 30s are the standard cuts |
| Container | MP4, MOV, or WebM |
| Video codec | H.264 recommended for universal playback |
| Frame rate | 23.976–30 fps, constant |
| Bitrate | 2.5 Mbps minimum · 8–30 Mbps source recommended |
| Audio | AAC stereo, 48 kHz, 192 kbps or better |
| Loudness | −24 LUFS ±2 · the broadcast (CALM) standard for TV |
| File size | Up to 250 MB |
Export once at the top of these ranges and stop there. Everything we serve derives from this file, so source quality is the ceiling for every screen. The minimums are hard floors from the exchanges we buy on — below 720p or 2.5 Mbps, premium inventory starts rejecting the ad.
What happens after upload
Drag the file into campaign creation or the Creatives page. We transcode renditions for every screen and connection speed from your master, so a strong source file is all you provide. A person then reviews every new campaign before it serves — usually within a few hours — checking playback quality and our brand safety standards. You're emailed the moment it's approved, and swapping creative later goes through the same review.
Questions about an edge case — a 6-second cut, a specific codec, a co-branded end card? Write to support@antebyte.com and we will spec it with you.
