TikTok app bundle video ad specs: 5 to 60 seconds, 720x1280

For TikTok's global app bundle ads, video runs 5 to 60 seconds (21 to 30 seconds recommended), in 9:16 at 720x1280 or larger, up to 500 MB, with bitrate of at least 516 kbps. Sume can hit the ratio, size and duration settings; bitrate is not exposed. Read 2026-09-29.

What does the app bundle page list?

9:16 is recommended. 16:9 and 1:1 are allowed at their own minimums.

How do I generate a 25-second vertical app ad?

seedance-2.5 lists 4 to 30 seconds per generation, at 480p, 720p or 1080p, with 9:16 in its ratio list, so a 25-second clip is one request. 720p clears the 720x1280 floor, on the reasonable reading that a 9:16 720p output is 720 wide; confirm the pixel size of the finished file with POST /v1/video-inspect.

    "duration": 25,
    "resolution": "720p",
    "aspect_ratio": "9:16"
  }'

What about a 45- or 60-second ad?

Above a single model's cap, join clips with Timeline 1.0 using output of 1080x1920 at 30 fps. Timeline's audio.duration_seconds runs 1 to 1800, so 60 seconds is well inside it. Cost is $0.10 per output minute.

What are the limits of this answer?

Sume does not offer bitrate control and does not submit ads to TikTok.
