Closed on Sunday AI and the TikTok Sound: A Legal Guide

The download is silent because Closed on Sunday AI delivers a video file, not a music release: every clip is a 12-second MP4 with no audio track. That is a deliberate design choice, not a bug, and it means the sound you add in TikTok, Reels or Shorts is your responsibility to choose and clear. This guide explains what the platforms license, how to attach a sound in four steps, where the beat should land in a 12-second edit, and which moves to avoid.

Our clips are exported as silent MP4s. There are three practical reasons.

First, music rights are territorial and platform-specific. A track that is cleared for use inside TikTok's app is not automatically cleared for a file you download, edit elsewhere and republish. Baking a song into an MP4 would hand you a file that is awkward to use legally almost anywhere.

Second, silence gives you a clean edit. You can drop the clip into TikTok, Instagram or YouTube Shorts and attach whatever sound the platform makes available in your country, then change your mind without re-rendering anything.

Third, it keeps the tool honest about what it is. Closed on Sunday AI generates video from your photos and a written prompt. It is an independent tool and is not affiliated with Ye, Sunday Service, Jesus Is King or Chick-fil-A, so it has no standing to distribute anyone's recording.

The short version: platforms license music for use inside their own app. They do not license it for you to take away.

• TikTok's Commercial Music Library is the catalogue cleared for business accounts and ads. Personal accounts can use the wider library, but that wider library is for organic posting inside TikTok, not for ripping out and reusing elsewhere.
• Instagram and Facebook have their own licensed catalogues for Reels and Stories. A track available in one app is often missing or restricted in another, and availability varies by country.
• YouTube Shorts works differently again. Content ID can match audio in your upload, and a claim may mean the video stays up with revenue going elsewhere, or it may mean a block, depending on the rights holder's settings.
• Cross-posting is the trap. A Reel with an in-app sound does not carry that licence to TikTok if you download the Reel and re-upload it. Attach the sound natively in each app instead.

None of this is legal advice, and rules change. Check the current terms for the platform you are posting on, and if you are posting commercially, assume the stricter set of rules applies.

1. Save the clip to your camera roll. Download your MP4 from the delivery link. Clips are 12 seconds, so you know exactly how much timeline you are working with.
2. Open TikTok and tap the plus button, then choose Upload rather than recording. Select your clip. You now have a silent 12-second video in the editor.
3. Tap Add sound at the top of the editing screen. Search for the track you want, or browse the trending list. When you pick one, TikTok attaches it to the post as an in-app sound rather than embedding an audio file you own. Use the volume slider to set the music level against the clip.
4. Trim the sound, not the video. Open the sound editing panel and drag the start point so the first strong beat lands where you want it. Then write your caption, add the relevant hashtags, and post.

The same pattern works in Instagram Reels and YouTube Shorts: upload the silent file, then attach audio from the app's own library. If you are specifically chasing the trend audio, our notes on the TikTok sound go deeper on how people are pairing it.

Twelve seconds is short. Treat it like a single shot with one payoff, not a mini film.

• Seconds 0–1: the hook. Start on the most striking frame — the choir mid-turn, the pet in the front row, the wide shot of the room. Do not open on a slow zoom. The scroll decision happens in the first second.
• Seconds 1–3: establish. Let the viewer register what they are looking at. If your clip has a camera move, this is where it should be underway.
• Seconds 3–6: the build. This is where a verse or a rising phrase usually sits. Keep the visual movement steady so the audio does the lifting.
• Seconds 6–9: the drop. Line the strongest beat, the first line of the chorus, or the biggest vocal moment with your best visual moment — a cut, a reveal, a reaction. If you only get one thing right, get this alignment right.
• Seconds 9–12: the hold and loop. Let the final image settle. A clip that ends on a clean, stable frame loops better, and looping is what drives repeat views.

Two practical notes. First, set the sound's start point rather than trimming the video, so you keep all 12 seconds of picture. Second, check the loop: if the last frame and the first frame are wildly different, the restart will feel jarring.

There are two broad routes, and they carry different risk.

The trend sound. Attaching the popular audio through the app's own sound library is the lowest-friction option, because the platform is licensing that use inside its walls. The trade-offs: the sound may be region-locked, it may be removed later, and it will not travel with your video if you download and repost elsewhere. Trend sounds also age fast.

A licensed track you clear yourself. If you want a specific song, or you are making something commercial, you need a licence from the rights holder — typically both the composition (publishing) and the recording (master). Stock and production-music libraries sell this in a straightforward way and are the sane choice for brand work.

A rough rule: organic posting inside one app, use the in-app library. Anything involving money, cross-posting, or a downloaded file, get a licence or use stock music.

• Do not re-upload the original music video's audio. Lifting the recording from the 2019 release and dropping it onto your clip is using a commercial recording without permission. It is also the fastest way to get muted, blocked or claimed.
• Do not claim your clip is official. Do not imply endorsement by Ye, Sunday Service, Jesus Is King, Chick-fil-A or anyone else. Your video is a fan-style AI remake, and the caption should make that obvious.
• Do not present the AI vocals as the original song. We do not promise the original song, and neither should your caption. Describe what it is: an AI-generated choir clip made from your photos.
• Do not strip a sound out of one app and re-upload it into another. That moves the audio outside the licence that permitted it.
• Do not use a personal-account sound in a paid ad. Commercial use needs the commercial catalogue or your own licence.

If a post gets muted or flagged, our troubleshooting guide covers the common causes.

Closed on Sunday AI is an independent tool. It is not affiliated with, endorsed by or connected to Ye, Sunday Service, Jesus Is King or Chick-fil-A. The name refers to a trend, not to an official partnership.

What the tool does: it generates 12-second silent MP4 clips from your photos and a written prompt, using eight presets plus a typed choir option, one lead per clip. One standard clip at 480p costs 15 credits, 720p costs 30 credits and 1080p costs 60 credits. The smallest one-time pack is $9.90 for 15 credits, and failed renders are refunded automatically. Delivery is by email as a private 7-day link, and the recipient needs no account.

What the tool does not do: supply music, clear rights, or grant you permission to use anyone's recording. That part is on you, and it is not complicated once you decide which route you are taking. If you are weighing up cost before you start, is Closed on Sunday AI free sets out the credit maths.

Because every clip is exported as a silent MP4 with no audio track. Music is added afterwards, inside TikTok, Reels or Shorts, using that platform's own sound library.

Not without permission from the rights holders. The original music video was released on 28 November 2019, and that recording is protected. Use the in-app sound library for organic posts, or license a track properly for anything commercial.

Using a sound through TikTok's own library is the standard, lowest-risk route for organic posting inside TikTok. The catch is that the licence does not follow the file if you download the video and repost it elsewhere.

Yes, but add the sound separately in each app. Do not export a version with audio baked in and upload that everywhere, because the licence that covered it in one app will not cover it in another.

Around the six-to-nine-second mark works well: hook in the first second, establish, build, then land your strongest visual moment on the biggest beat, and hold a clean final frame so the loop feels natural.

It is good practice to say the clip is AI-generated, and it keeps you clear of implying anything is official. Keep the caption honest about what the video is and where the sound came from.
