Posting Your AI Drama to TikTok, YouTube Shorts and Instagram Reels

Quick answer: Make the project vertical from the start: choose 9:16 Portrait in step 1, because the frame cannot change later. Composite each episode, download it (the download is the full-quality file), and upload that file to the platform rather than posting a SceneMixer link. Turn on the platform’s own “made with AI” label when you post. Add captions and any music in the platform’s editor or your own, since the site delivers a clean picture with voices and ambient sound. And open each episode on a hook: the first seconds decide whether people keep watching.

Composite one finished episode, download it, and play it on your phone full screen before you post: that is what viewers will see.

Vertical from the first step

Phone feeds are vertical. Pick 9:16 Portrait on the step 1 settings screen; it sets the frame of every video in the project and cannot be changed after you continue. A landscape project can still be posted, but it shows with bars above and below. Vertical or landscape.

Which file to post

Composite the episode once every segment has a clip, then download it. The download is the full-quality original; the player and share pages use a lighter copy. Upload the downloaded file natively. A SceneMixer share link is fine for sending a preview to a friend, but feeds favour videos uploaded to the platform itself. Composite and share an episode · Download versus play version.

For a cleaner picture, draft at a low tier and generate the final segments at a higher one; the composite is only as sharp as the tier you used. Draft at 480p, finish at 1080p.

The AI label

Downloads from an account without a paid plan carry a small SceneMixer AI label in the corner. On a paid plan, downloads are label-free by default; videos shared through a SceneMixer link always carry it. Separately, TikTok, YouTube and Instagram each have a setting to mark a post as made with AI; turn it on. Platforms can limit or remove realistic AI content that is not labelled. The AI label switch · AI short drama compliance.

Captions and music

The clip has dialogue and ambient sound but no subtitles burned in, which suits these platforms: add captions with the platform’s auto-captions or in your editor, so people watching on mute can follow. For music, use the platform’s licensed library or your own licensed track, kept well under the voices. Adding background music.

The first seconds

Viewers decide almost at once. Open on the conflict, a line that raises a question, or a striking image, not an establishing shot; end each episode on an open question so the next one gets watched. You can shape this in the script before it is read, or by editing the first shot of an episode. Write hooks and cliffhangers into your script.

Length and series

Platforms set their own maximum lengths and change them from time to time; check the current limit before posting a long episode. Post a series in order and name the parts in the title or the first frame of the caption, so a new viewer can find episode 1.
