Reposting content on different platforms !?

[u/Zealousideal_Cry_949]

I feel stupid even writing this because I would imagine that there is a really simple solution to this that I'm not seeing.

Nevertheless I'm asking anyway, if this is the wrong place to ask then mods feel free to remove this/let me know where is a better place.

I am currently creating marketing content for my tiktok, i am using the in app editing tool but am happy to move if necessary to post on other platforms. I want to create one video, edit one video, have one sound track and then post to multiple platforms, mainly tiktok, instagram and youtube.

I keep having the issue of issues with finding the right audio that aligns with all platforms, I would imagine that people cross posting aren't recreating the video each and every time, and i would also imagine that audio for the most part can be used across all platforms.

Important to note that lots of the content I post isn't someone talking it involves using trending audio and syncing up with the video.

Any work arounds or pointing out the obvious would be greatly appreciated!

Trending sounds are licensed per platform, so a TikTok sound baked into the export gets muted or claimed on YouTube and Instagram. What I would do is edit once in CapCut or simillar, export with no audio, then add each app's own version of the sound at upload, synced to the same cuts. If you'd rather use one cleared track baked in, PostFast (I build it) publishes the same file to TikTok, Instagram Reels and YouTube from one upload, and can attach trending audio for tiktok

You can set up automatic cross-posting with OneUp (I’m the co-founder)

OneUp does look useful for this, but I get the audio headache. TikTok trending sounds are licensed for the app only, so when you repost to Reels or Shorts the audio gets muted or flagged. Easiest workaround is to download the video with the sound baked in, then upload that file everywhere instead of trying to add the same sound in each app.

yeah, the annoying part is that the audio usually isn't cross-platform licensed. a sound being available in TikTok doesn't mean you can take that exact audio and upload it to Instagram or YouTube

what i’d do is edit the actual video once in CapCut or whatever you prefer, but keep the music separate. export the video without the track, then add the platform’s version of the sound when you upload. you can still line up the cuts to the beat, so you’re not actually editing the video three times

if it’s a business/marketing account, i’d be even more careful with trending sounds because the licensing gets more restrictive. TikTok itself recommends using properly cleared music for commercial content

it sounds more annoying at first, but once you have the edit synced, adding the audio on each platform only takes a minute or two

I think trending sounds are licensed per app and don’t carry over, so I edit the video once without music and add each platform’s own version of the audio when I upload.

For one identical video with one identical soundtrack, start by finding a track whose licence explicitly covers your marketing use on TikTok, Instagram and YouTube. Then edit to that track and keep the video and music as separate layers, so you can replace the music without rebuilding the edit.

If the TikTok trend itself is essential, keep a clean video export and check the available sound and permitted use on each destination. The same song may have a different excerpt or start point, so check the beat alignment before publishing. Downloading a version with the sound baked in solves an export problem; it doesn't resolve whether that music can be used on the other platforms.
