Your ADDICTED duet from Jisoo Addicted AI downloads as a 15-second, 9:16 MP4, which is the vertical shape TikTok, Instagram Reels and YouTube Shorts all accept. Upload the file, add a short caption, tag the person who dances with you and use the hashtags you see on other posts, such as #JISOO_ADDICTED and #ADDICTEDchallenge. The one thing to think through is the music, because the sound mixed into your file is the trend's original audio and each platform has its own music library and rules.
Key takeaways
- The file is a 15-second, 9:16 MP4, 720p by default. That fits all three platforms without cropping, and you can pick 1:1 or 16:9 if you want them.
- The trend sound is already mixed into the video. The song, ADDICTED, belongs to its rights holders, and each platform decides how it treats music in uploaded files.
- Caption and hashtags are for people to find and enjoy the clip. Tag the partner you made it with. Say it is AI-made, which many platforms also ask for.
- There is no proven best time to post, and this article does not invent one. Test your own audience.
- The site is independent and not affiliated with JISOO, ROSÉ, BLACKPINK, their agencies or labels, or TikTok. Videos use ByteDance Seedance models.

What format does the finished video come in?
The finished video comes as a 15-second MP4 in 9:16 vertical at 720p by default. Vertical 9:16 is the native shape of TikTok, Reels and Shorts, so the clip fills the screen on all three without black bars or cropping. You can also choose 1:1 or 16:9, and the model tier decides which resolutions exist: Standard offers 480p and 720p, while Pro and Ultra also offer 1080p.
Fifteen seconds sits comfortably inside every platform's short-video limits. It is also close to the length of the two-person stretch of the original dance, which is a 38-second vertical clip that was posted on TikTok on 2026-10-31. Your version is shorter by design, so there is nothing to trim.
The file name is jisoo-addicted-ai.mp4. Rename it if you like, since platforms do not read the name. Keep the original file and upload that, not a screen recording. A screen recording adds interface elements, compresses the picture a second time and may cut the sound.
A practical check before posting: play the clip once with the sound on. Look at the faces, the hands and the corridor, and listen for the beat. If something is off, the guide to eight common duet fails lists what to change, and failed or blocked renders return their credits automatically.
How do I post it on TikTok?
On TikTok, open the create screen, choose to upload from your phone, pick the MP4 and add your caption and hashtags on the post screen. Because the file already has the trend sound inside it, you do not need to add a sound at all.
The place to be careful is the sound picker. Adding a sound from TikTok's library on top of the file would layer two audio tracks. Leave the sound as it is and check the volume balance on the preview. If you want to use TikTok's own copy of the song instead, you can lower or mute the file's audio in the editor and add the library sound, which keeps the clip tied to the platform's licensed catalog. That is your choice and it depends on what is available in your region.
TikTok also asks creators to label AI-generated content, and the platform provides a setting for it. Turn it on. It is honest, it takes seconds and it avoids a takedown for unlabeled synthetic video. The site is unaffiliated with TikTok, so check the app's current prompts and settings, since they change.
Set the cover frame to a moment where both faces are clear. If the post screen lets you choose a cover from the video, pick a frame near the start, when the dancers are in view.
How do I post it on Instagram Reels?
On Instagram, tap the plus icon, choose Reel, pick the MP4 from your library and trim nothing, since the clip is already the right length. Add a caption on the final screen, tag your partner and share to Reels. You can also share to your Story or main feed from the same screen.
Reels has its own music library and its own rules about audio in uploaded files. If the platform detects third-party music it may mute the audio, limit where the Reel is shown or show a notice. That is the platform's system, and the outcome depends on the rights situation, so do not assume the sound will stay on. Watch the Reel after it processes.
Reels also lets you add a cover image and a text overlay. A short on-screen line over the first second can help people understand the clip with the sound off. Keep it brief so it does not cover the dancers.
Instagram has a label for AI-generated content. If it is offered when you post, use it. Check the current wording in the app.
How do I post it on YouTube Shorts?
On YouTube, tap the plus icon, choose to upload a video and select the MP4. A vertical video under the Shorts length limit is treated as a Short automatically, and a 15-second clip qualifies. Add a title, which Shorts uses more than people expect, and a description with your hashtags.
YouTube has its own Content ID system, which scans uploads for music that belongs to someone else. A claim does not always mean a removal. It may mean the audio is muted, the video is blocked in some regions or revenue goes to the rights holder. If a claim appears, YouTube's notice explains what it affects. You can often resolve it by swapping the audio for a track from YouTube's own library inside the Shorts editor.
Shorts asks creators to disclose realistic altered or synthetic content. A dance video of real-looking people made by AI is the kind of thing that disclosure is for. Turn it on when the upload form offers it.
What should I write in the caption and hashtags?
Write a short, honest caption and use a few hashtags seen on other posts. You do not need a clever line. A clip that shows a hallway duet works because people recognize it, so the caption can be light.
Here are the kinds of caption that fit, without any claims you cannot back up:
- A plain line that names the trend, such as "Our ADDICTED hallway duet" with the AI label.
- A tag-your-partner line, such as "Tag the person who has to dance this with you."
- A neutral line about how it was made, such as "Made from two photos with an AI video tool."
Hashtags that appear on posts about this trend include #JISOO_ADDICTED and #ADDICTEDchallenge. Note that #ADDICTEDchallenge is just a tag people use. It is not proof that an official challenge exists, so avoid wording like "join the official challenge". Use two to five hashtags at most. A long block of tags looks like spam on all three platforms and does not help the clip travel.
Do not use the names of JISOO, ROSÉ or BLACKPINK in a way that suggests they made, joined or approved your video. The site is not affiliated with them, their agencies or labels, or TikTok, and your caption should not imply otherwise.
How should I handle the music question?
Treat the music as someone else's property and follow each platform's rules. The sound mixed into your file is the trend's original audio, taken from the song ADDICTED. The song belongs to its rights holders, and a purchase on this site does not grant any rights to it.
This is not a legal opinion, and it is not a promise about what a platform will do. It is a set of facts worth knowing. TikTok, Instagram and YouTube each run their own music libraries and their own detection systems. A track licensed for use inside one platform's editor may not be licensed for the same sound baked into an uploaded file. What happens varies: the audio may play, be muted, be limited to some countries or draw a claim.
You have three reasonable paths. The first is to post the file as it is and accept what the platform does with the audio. The second is to mute the file's audio and add the same song from the platform's own library, which usually keeps it inside a license the platform holds. The third is to post it without the trend sound and use a track the platform offers you. Whichever you choose, you remain responsible for what you upload.
If you plan to use the video commercially, such as in an ad or on a brand account, treat the music as unlicensed unless you hold the rights. Platforms often have separate commercial music libraries for business accounts. Read the current terms before you post.
How do I tag my partner and make the clip feel personal?
Tag your partner in the caption and, where the app allows, in the post itself. The clip is built on two people, so the person next to you in the hallway is the obvious audience. On TikTok you can mention them in the caption and add them as a tag. On Instagram you can tag them in the Reel and in the caption. On YouTube you can mention their channel in the description.
Ask before you tag. Because the video is made from their photo, they should know it exists and agree to it. Do not use someone's photo without their permission, and never upload photos of minors or of celebrities, including JISOO and ROSÉ. The site blocks both. A friend who finds out about a video of themselves from a public tag may not be pleased.
A few small habits help the post feel personal without any tricks. Send the clip to your partner first, in a private message, so the reaction is theirs. Reply to comments in the first hour, since that is when friends are most likely to see it. And keep the AI label visible, so no one is misled.
When should I post, and how often?
Post when your own audience is awake and likely to look. No public study in this article's scope gives a reliable best time for ADDICTED duets, and posting times differ by country, age group and account. Any exact hour you read without a source is a guess.
A sensible approach is to check your own analytics. TikTok, Instagram and YouTube all show when your followers are active. Post at one of those times, note the result and try a different time for the next clip. After three or four posts you will have a pattern that belongs to your account, which beats any general advice.
Posting more than one version is fine, and the platforms treat each upload separately. If you make a second clip with different photos or another model tier, post it as its own video and not as a duplicate. Each render of the Hallway Duet can come out slightly different, even from the same photos. Each render costs credits: Standard 720p is 10 credits and the Single pack is $6.99 for 10 credits. The pricing page lists the larger packs.
The practical order, then, is simple. Make the clip, check it with the sound on, post it with an AI label, tag your partner and keep the caption honest. If a platform changes what it does with the audio, that is its decision, and the rights to the song stay where they are.
Frequently asked questions
Why does my uploaded ADDICTED duet sound different or go silent?
A platform may mute, limit or claim audio it recognizes as third-party music, because the sound in your file is the trend's original audio from a song that belongs to its rights holders. Watch the post after it processes. If it was muted, you can add a track from the platform's own library instead.
Should I mute the video and add the song inside the app?
That is a reasonable option. Muting the file's audio and choosing the song from TikTok's, Instagram's or YouTube's library keeps the music inside a license the platform holds, where it is available in your region. Check the volume on the preview so the library track is not too quiet.
Do I have to label the video as AI-generated?
The platforms ask creators to disclose realistic synthetic content and each has a setting for it. Turn it on when the upload form offers it. It is honest, it is quick and it protects the post from being removed. Menus change, so check the current wording in the app.
Is #ADDICTEDchallenge an official challenge I can join?
No. It is a tag people use on posts, and its presence does not prove that any official challenge exists. Use it to be found next to similar clips, along with #JISOO_ADDICTED, and avoid wording that suggests approval from JISOO, ROSÉ, BLACKPINK, their agencies or labels, or TikTok.
Can I post the same file on all three platforms?
Yes. A 15-second 9:16 MP4 fits TikTok, Reels and Shorts. Upload the original download to each one and not a screen recording, set the AI label per app and watch how each platform treats the audio, because the three handle music differently.
