A creative is transcoded to the profiles of each stream, so maximum quality is needed on input.
| Parameter | Requirement |
|---|---|
| Video | 1920×1080, 25 fps, H.264, 15 Mbps or more |
| Audio | AAC, 48 / 96 kHz, 128 kbps, one 2.0 stereo track |
| Container | .mp4, .mov, .mxf, .mpeg |
| Tracks | Both video and audio are mandatory |
| Loudness | Normalized automatically to EBU R 128 |
Tips
- The creative must be transcodable: no protection, no variable frame rate.
- Choose creative durations to fit the channel's typical break lengths — the remainder is filled with the filler.
- Ad server line items must include the 1920×1080 size: a request without it often returns an empty response. See Empty VAST or NO AD.
- Free GAM limits built-in creative hosting to 30 MB — compress or use external hosting.
Note
A new creative is transcoded before its first impression, so the first request usually gets the filler and the creative appears in later breaks.
Validating the creative's content (rights, music, documents) is the responsibility of the sales house and the rights holder: Roles and responsibilities.
