TrialReelYou made the video once — it should reach people everywhere. Cross-posting your own videos is fine. Doing it lazily is what costs reach.
1. Keep a clean master
Export from your editor (CapCut, Premiere, your phone's editor) before you post anywhere, and save that file. Upload the clean file to each app. Downloading from TikTok gives you a file with TikTok's watermark, and Instagram has said watermarks and speed changes don't make content original.
2. Check the length
Reels and Shorts both allow up to 3 minutes; YouTube counts square or taller videos as Shorts. If your TikTok is longer, cut a tighter version.
3. Change the first second for each feed
The opening that works on TikTok may not work on Reels. Try a different on-screen hook per platform — it's the cheapest test there is.
4. Rewrite the caption and title
- Instagram: a short caption, a reason to send it to someone.
- TikTok: short, native, a couple of relevant keywords.
- YouTube Shorts: a clear, searchable title.
5. Post where it fits, when it fits
You don't have to post everywhere the same minute. Let each platform's own numbers tell you which ideas travel and which stay native.
6. Learn per platform
A video can flop on one app and win on another. Track views per platform for each idea, and make more of what wins where.
