What each platform's rules say
| Platform | What its rules say |
|---|---|
| Reels that are low-resolution or watermarked, or that have already been posted on Instagram, are shown less. | |
| Your own footage counts as original. Copies of a video get less distribution, and Facebook advises avoiding visible third-party watermarks and content that is visibly recycled from other apps. | |
| TikTok | Duplicated content isn't recommended. For the Creator Rewards Program, content copied from others or carrying their watermarks isn't original, and a video has to be uploaded after you join. |
| YouTube | The reused content rule is about other people's work: short videos compiled from other social media sites can't earn, while content that mainly features the creator who uploaded it can. |

What to change for each app
- Length. On YouTube, a Short over one minute with an active copyright claim is blocked worldwide (YouTube Help), while TikTok's Creator Rewards Program counts only videos of at least one minute. If you use claimed music and want TikTok rewards, make two cuts.
- Captions. If your captions are burned into the video, turn each app's own captions off for it, or the words show twice. The captions guide has each app's steps.
- Text placement. Each app draws its buttons over a different part of the frame, so keep text and faces inside the area all four leave clear. See the safe zones guide.
- Post copy. Write the title, caption and hashtags for each app rather than pasting one everywhere.
- AI labels. If AI made the video look real, turn on each app's AI label. The AI labels guide has the steps.
Sharing from Instagram to Facebook
Instagram can share a reel to your Facebook account when you create it, in the Instagram app for iPhone or Android, and can share your future reels automatically. Instagram says the feature isn't available to everyone, and that a reel can only be shared at the time you create it (Instagram Help). Since June 2025 every video posted to Facebook is shared as a reel (Meta Business Help).
A clean way to post one short everywhere
- Export once from your editor, vertical, at 1080 x 1920, with no app's watermark on it.
- Make a second cut if one app's length rule needs it.
- Upload your own export to each app, not a copy saved from another app's player.
- Write the title, caption and hashtags for each app.
- Turn on the AI label where it applies, and the captions setting that matches your file.
- Watch each app's numbers on their own: the same video can do well on one and not on another.
Where ViewGum fits
ViewGum exports one 1080 x 1920 MP4 and writes the title, caption and hashtags for TikTok, Reels, Shorts and Facebook, so the same short goes to each app as its own upload with its own post copy.
Questions
Will TikTok or Instagram show my video less because I posted it on another app?
Their published rules don't say so. Instagram shows watermarked reels and reels already posted on Instagram less, TikTok doesn't recommend duplicated content, and Facebook reduces copies. A clean upload of your own video is none of those.
Can I upload a video I saved from TikTok to Instagram?
Instagram shows watermarked reels less, and Facebook advises against visible third-party watermarks, so upload a clean export from your editor instead.
Does Instagram share reels to Facebook automatically?
It can. When you create a reel in the Instagram app you can share it to Facebook, and you can turn on sharing for future reels. Instagram says the feature isn't available to everyone.
