Understanding TikTok Video Requirements
Overview
Social Cascade publishes videos to TikTok. Image-only and text-only posts can't be sent to TikTok from Social Cascade. This article lists the limits to check before you schedule TikTok content.

How Social Cascade Handles Your Video
Social Cascade prepares uploaded videos for social platforms: it converts them to MP4 and scales anything larger than 1080p down to 1080p. This usually takes under a minute after upload. You can't publish until it finishes. If you try, you'll see "Video is still being processed. This usually takes under a minute — try again shortly."
Videos recorded in the Social Cascade Teleprompter app or the Web Teleprompter are handled automatically.
When TikTok Isn't Offered
- Calendar: If the content has no video, TikTok doesn't appear under Post on: when you schedule it.

- Upload your own: TikTok is switched off with a short reason, such as "TikTok needs a video." or "TikTok needs a vertical or wide video."
- Teleprompter: Recordings always include video, so TikTok is available when it's connected.
If a post reaches TikTok without a video, it fails with "TikTok requires video content".
Text Length
The 2,200-character limit applies to the full published text: your caption, any context you add, your team's editorial disclaimer, attribution, and hashtags. If the post is too long, Social Cascade tells you how many characters to cut.
Tips:
- Keep captions to 1–3 sentences and put the key message first. Long captions are cut off in the TikTok feed.
- Add a few relevant hashtags.
- TikTok may remove line breaks from captions posted from other apps.
FAQ
Q: Can I post images to TikTok through Social Cascade?
A: Not yet. Social Cascade sends video to TikTok. Post photo posts in the TikTok app.
Q: What if my video is longer than 10 minutes?
A: TikTok won't accept it. Trim it to under 10 minutes before you schedule it.
Q: Can I post the same video to TikTok and Instagram?
A: Yes. Select both platforms when you schedule. Each platform gets the same video and caption, within that platform's limits.
Q: Does Social Cascade change my video?
A: It converts uploaded videos to MP4 and scales them to 1080p at most, so they upload reliably. Your content isn't edited.
