I want to make money from editing TikTok videos.

You should get familiar with CapCut. it’s the simplest and easiest app for beginners like you.

Yes—if you want one upload to publish across several channels, you generally connect/authorize each destination account once so the scheduler has permission to post. Keep a clean master export (not a TikTok download), then adjust the caption/cover and check each platform's format before publishing. I built PostOnce.to for that workflow: it crossposts in every direction between TikTok, Instagram, YouTube, Facebook, X, LinkedIn, Threads, Pinterest and Bluesky. It picks up a new post and crossposts it within about 10 minutes, can repost your own TikToks without the watermark, and can re-publish older posts too. It includes a 7-day trial.
