TikTok video package opening and end scenes: 1-10 seconds, 720x1280

TikTok's Specifications for Video Packages page lists opening and end scenes as MP4, MOV, FLV, MKV or WebM files between 1 and 10 seconds long. Custom templates are a separate item: Lottie zip format, under 16 seconds, at most 30 fps, at 720 by 1280.

The numbers on the page

Only the figures the page states.

What the page leaves out

The page does not give file size, bitrate or aspect ratio beyond the template resolution, and the fetched text does not say which ad formats use video packages. Check Ads Manager for the placement you buy before building scenes.

Cutting an opening scene with Sume

Sume's video trim takes a clip you already hold on media.sume.com, a start and either an end or a duration, and returns a new MP4. Its docs list a duration range of 0.2 to 900 seconds and an optional output of width, height and fps; width and height run 256 to 2160 and fps can be 24, 25, 30 or 60. A 4-second opening at 720 by 1280 and 30 fps is inside both sets of numbers.

• Choose duration of 1 to 10 for an opening or end scene.
• Use precision: exact (the default) when you set output; the docs say conform needs exact.
• Check the returned duration_seconds and warnings before upload.

Which format to export

The page lists several containers, so MP4 is the simplest choice and it is what Sume's trim returns. Keep the opening short enough that the viewer reaches the main content quickly, and check the final length of each scene after the cut. If an upload is refused, re-read the page, since it is the only source here for these numbers.

What Sume does not make

Sume does not produce Lottie template files, and it does not upload a video package to Ads Manager. For the Lottie item you need a design tool that exports Lottie.
