You edit a video in TikTok, add music from its sound menu and download the result. Can you upload that file to YouTube? You need rights for the song in the downloaded file, not only for the video you made.
Find the recording used in the export. A song title alone is not enough: another performer may have made a different recording. Read the licence for the actual file and check whether it covers both platforms and your planned use. “Royalty free” by itself answers none of those questions.
Work through one named track
“Carefree” by Kevin MacLeod, ISRC USUAN1400037 is listed by its creator under Creative Commons Attribution 4.0. Incompetech's licence page offers a free route with credit. CC BY 4.0 permits commercial sharing and adaptation, including synchronising music with video, if the attribution terms are met. That is a usable route for this exact track; it is not a licence for a cover version or another recording with the same title.
We downloaded the creator's file and used 12 seconds in the card below. The video carries the credit on screen. It has not been uploaded to either platform.
Credit for this excerpt: Music: “Carefree” by Kevin MacLeod (incompetech.com), CC BY 4.0. We shortened the recording and paired it with our text card. Here is the original track.
| Question | YouTube Short | TikTok post |
|---|---|---|
| Which audio? | Use the recording linked by the named Incompetech track page, not a different upload | Use that same source recording only if its licence and the post type match |
| Copyright route | CC BY 4.0 permits commercial video use with attribution; keep the track-page record | Same CC BY route; for a branded post outside TikTok's Commercial Music Library, confirm necessary rights in TikTok's disclosure flow |
| Credit | Name title and artist, link source and CC BY 4.0, say if shortened or mixed | Put the equivalent credit and licence link in the TikTok caption or another reasonable credit location |
| After upload | A Content ID match may still need licence evidence | Check any mute or rights notice; permission on paper does not guarantee platform acceptance |
Draft the same credit for both uploads. For our card it reads: Music: “Carefree” by Kevin MacLeod (incompetech.com), CC BY 4.0: https://creativecommons.org/licenses/by/4.0/ — original recording excerpted and paired with our text card. Add the track link. If you mix the music under narration, change the last part of the credit to describe that edit. Keep the licence record beside the project file so the next editor does not swap in an unlicensed version.
Why a platform music menu is a different route
TikTok Support says its Commercial Music Library is pre-cleared for commercial use on TikTok. It also says a creator using original music or a track outside that library for brand-promoting content must confirm they have the necessary rights. The CML statement does not grant YouTube use of a CML recording.
YouTube Help lists music you made and properly licensed third-party music as options, but warns that Content ID may flag even a track described as free. Its Creator Music licence details say those tracks are for long-form videos, not Shorts, and the licences do not transfer to other platforms. Do not assume a YouTube music option can be carried into TikTok.
Check the actual exports
- Save a clean video master with no app-added music. Name it so nobody mistakes a downloaded post for the source.
- If using “Carefree,” get the audio from the identified creator page. Keep the download, track URL, licence text, date and exact export filename together.
- Make the YouTube and TikTok cuts from that master. Watch each final file with sound and check that the recorded song is the one in your rights log.
- Place the required credit in both upload drafts. For a brand-promoting TikTok, complete its disclosure and music-rights confirmation based on the actual licence.
- After posting, inspect both live videos for a mute, claim or attribution error. A successful upload in one app proves nothing about the other.
If you instead add music from TikTok's CML inside TikTok, keep that as a TikTok-specific version. Make a separate YouTube version from the clean master with music licensed for YouTube or no music. The cross-posting guide covers the wider upload workflow. Use the pre-publish checklist to inspect each final file before posting.
