What you get at the end of a sprint
Every ad, in every shape your placements need, named so your results can be read. Platforms change their specs from time to time, so check theirs before you upload. These are ours.


Shapes and sizes
| Vertical 9:16 | 1080 × 1920. Reels, Stories, TikTok and YouTube Shorts. |
|---|---|
| Portrait 4:5 | 1080 × 1350. Facebook and Instagram feeds. |
| Square 1:1 | 1080 × 1080. Feeds and placements that crop to square. |
| Widescreen 16:9 | 1920 × 1080. YouTube in-stream, on request. |
Files, sound and captions
| Length | Up to 15, 30 or 60 seconds, by sprint size. |
|---|---|
| Format | MP4, H.264 video, AAC audio. |
| Captions | Burned in, so the ad works with the sound off. |
| Safe zones | Text, logos and faces kept out of the top and bottom of vertical frames, where platform buttons and captions sit. |
| Sound | Mixed for sound on. Music cleared for use in ads. |
| Names | ANGLE_HOOK_EXECUTION_SHAPE_VERSION, for example ROUTINE_HOOK-B_DEMO_9x16_V03. |
| Delivery | A shared folder, organized by angle, with the test plan alongside. |
