Post your iPhone Kupi video as 9:16 on TikTok, Instagram Reels and YouTube Shorts, keep or swap the sound inside the app, add a short caption with a few relevant hashtags, turn on the platform's AI label, and keep the video out of paid ads because the song is not licensed for them. iPhone Kupi AI makes the 15-second foldable-phone dance from one photo, and this guide covers what to do after you download the MP4. It does not promise views, and it does not quote any platform's rules word for word, because they change.
The trend itself is big. Win William's original hotel-room clip was posted on 23 October 2026 and had passed 74 million views by 29 October, and remakes followed within days. A video that arrives in that window competes with a lot of similar clips, so the choices below (frame, sound, caption, label) matter more than usual.
Key takeaways
- 9:16 fits all three short-video platforms. Use 1:1 only for a feed post.
- The MP4 from iPhone Kupi AI already carries the original sound. On TikTok you can also use the in-app sound or a DJ version.
- Hashtags such as #iphonekupi, #iphonekupidance, #iphoneduo and #winwilliam describe the trend. They do not guarantee reach.
- Check the platform's current AI label rules and use the label. Do not post a likeness of someone who did not agree to it.
- The song is not licensed for ads, so keep it organic.
Should I post the iPhone Kupi video in 9:16 or 1:1?
Post it in 9:16 for TikTok, Reels and Shorts, because it fills a phone screen and is the shape those platforms are built around. iPhone Kupi AI renders in 9:16 by default, and 1:1 and 16:9 are also available when you create the video.
| Where you post | Best ratio | Why |
|---|---|---|
| TikTok | 9:16 | Full-screen vertical feed |
| Instagram Reels | 9:16 | Reels are vertical |
| YouTube Shorts | 9:16 | Shorts are vertical |
| Instagram or Facebook feed | 1:1 | Square fits the feed grid |
| YouTube (long form), desktop embeds | 16:9 | Landscape players |
The ratio is part of the render, so choose it before you press the button. Cropping a 16:9 video into 9:16 afterward cuts off the sides, and in this dance the dancer goes from close to full body, so you can lose the phone or the head. If you want the same dance on two platforms with different shapes, render each shape separately.
One more point about the frame: the dance starts with the person very close to the lens and ends with them walking out. Platforms overlay buttons and captions on the lower and right edges of a vertical video, so a caption you add yourself should sit in the upper middle, not the bottom.
Why does a 15-second video work for short-form?
A 15-second video works for short-form because it is long enough to show the full dance and short enough that people watch it to the end. iPhone Kupi AI makes every video 15 seconds, the same length as the original, so it fits all three platforms without trimming.
The routine also has a built-in hook. The first second shows a person holding a folded phone close to the camera, and the phone opens at 1 to 2 seconds. The big visual moments are the full unfold at 4 to 5.5 seconds and the toss at 9.5 to 10.5 seconds. If you add your own text on screen, put it in the first 2 seconds, before the unfold, so it is read while the person is still close to the lens.
Short clips can also loop. The video ends with the dancer walking out of frame, so a platform that auto-loops will jump straight back to the person sitting near the lens, which makes a loop feel natural.
Should I keep the original sound or use TikTok's official sound?
Keep the original sound if you want the video to work everywhere, and swap to TikTok's official sound or a DJ version if you post there and want the clip tied to that sound's page. The MP4 from iPhone Kupi AI includes the song "Базовый минимум" by SABI and MIA BOYKA, laid over the video after it renders, because the model itself outputs no sound.
The official TikTok sound is named "Базовый минимум - Sabi & MIA BOYKA". Using it inside TikTok does a few things:
- The video is linked to the sound's page, so people who tap the sound can find it.
- The sound plays from the platform's own library, which is the safer route for rights.
- You can pick a different cut of the song, such as an Indonesian DJ version, because many DJ edits of the track circulate. Check that the one you pick is available in your region.
How to do it, in general terms: upload the MP4, open the sound options in the editor, choose the in-app sound, and lower or mute the original audio so the two do not overlap. The exact buttons change between app versions, so follow what the app shows you.
A swap can cost you some sync, since the in-app version may start at a different point than the track in your file. Preview the video with the new sound and trim or shift the audio until the toss at around 9.5 seconds lands on a beat. The iPhone Kupi song page explains where the track comes from, and the meaning page covers the lyric.
On Reels and Shorts, the platform's own music library may offer a different set of tracks, and a track that is on TikTok may not be on the others. If it is not available, keep the original audio in your file.
What caption and hashtags should I use?
Use a short caption that names the trend in plain words and a few hashtags that people search for. Do not copy a caption from a viral video word for word. A caption that describes what happens is better for search and does not look like a repost.
Some structures that work without making any claims:
- A one-line description. "The iPhone Kupi dance, but it's me."
- A question. "Who else is doing the foldable phone dance?"
- A tag of the sound or creator. Mention the sound name; tag Win William only if you mean to credit the trend's origin, and know that this does not mean he endorses your video.
- A duo prompt. "Tag the person you'd do the duo version with."
For hashtags, the ones used around this trend are #iphonekupi, #iphonekupidance, #iphoneduo and #winwilliam. People also search "iPhone Duo dance" and "iPhone Kupi", so those words in the caption text help search on TikTok and Instagram. Keep it to a handful. A long block of hashtags looks like spam and does not improve reach.
Do not write numbers like "10 million views" or "going viral" about your own clip, and do not claim the video is official. The trend's reach is a fact about the original. Your video has to earn its own.
Do I have to label the video as AI-generated?
Check the platform's current AI label rules and use the label. TikTok asks creators to label AI-generated content, and Instagram and YouTube have their own disclosure settings. The rules and where the toggle sits change, so read the current help page on each platform instead of relying on a blog post, including this one.
A few practical points:
- Use the platform's own AI-generated label if the app offers one in the upload screen or the settings.
- A text note helps. Adding "AI-generated" or "made with AI" in the caption is clear and costs nothing.
- A video of a real person's face is the case platforms care about most. A video made with your own photo and your consent is the safe case. A video of a celebrity or a friend who did not agree is not.
- If a platform removes or restricts the video, check its AI policy and appeal through the app if you think it was a mistake.
iPhone Kupi AI is an independent tool and is not affiliated with TikTok, Apple, Win William, SABI or MIA BOYKA. The phone in the video is a generic foldable with no logo, and the site takes no position on how any platform treats AI content. Upload only photos of adults who agreed to be in the video.
Can I use the video in an ad?
No, do not use an iPhone Kupi video with this music in a paid ad. The song "Базовый минимум" is not licensed for ads through iPhone Kupi AI, and commercial use of music is handled by the platform's rules for business accounts. The safe route is organic posts from a personal or creator account.
If you run a business account, most platforms limit you to a commercial music library. A track that works on a personal account may be unavailable or muted on a business one. If you want a brand to use the format, ask the rights holder, or use a track from the platform's commercial library and expect a different feel.
A video of a real person also raises likeness questions in an ad. Get written permission from the person in the photo before using their likeness in anything commercial.
When should I post, and how often?
Post when your audience is online, and post a few related videos rather than one. A trend this big is crowded, so the first few hours of a post can matter, but there is no verified best time that applies to everyone. Look at your own analytics in each app after a few posts and pick the hours where your followers are active.
Some habits that tend to help:
- Post the first version quickly. A trend loses attention fast.
- Try different scenes. iPhone Kupi AI has 7, including the original hotel night, a rooftop skyline and a neon club. Posting two different scenes gives you two chances to see what your audience prefers.
- Make a duo version. The iPhone Duo dance page describes the two-person template, which gets people to tag each other.
- Reply to comments with a second clip if one idea gets attention.
Do not buy views or engagement, and do not expect any set number of them. Nothing here comes with a guarantee.
What should I check before I press post?
Run through this list on the final MP4.
- Ratio. 9:16 for TikTok, Reels and Shorts.
- Faces and the phone. Watch it once with the sound on. If a glitch sits in the last second, trim it. If it is earlier, consider a new render; the glitch guide, how to fix iPhone Kupi video glitches, goes through each one.
- Sound. Either the original audio from the file or the platform's sound, not both at once.
- Caption. A line of text and a few hashtags.
- AI label. On, using the platform's current option.
- Consent. Everyone in the video agreed.
- Not an ad. Organic use only.
- Download time. iPhone Kupi AI keeps the finished file for 24 hours, so save it to your phone or computer before you close the page.
If you do not have a video yet, make your iPhone Kupi dance video from one clear photo. Credits never expire, a Standard 720p video costs 10 credits and other tiers run from 5 to 93, and failed renders return their credits. The pricing page has the packs.

Frequently asked questions
Which hashtags go with the iPhone Kupi dance?
The hashtags used around the iPhone Kupi dance include #iphonekupi, #iphonekupidance, #iphoneduo and #winwilliam. Pick a few that fit your video and keep the caption short. Hashtags help people find the trend but do not guarantee reach. A video made with iPhone Kupi AI is unofficial, so avoid wording that suggests the creator or the artists endorse it.
Can I post the same iPhone Kupi video on TikTok, Reels and Shorts?
Yes, one 9:16 file works on all three. Upload the same iPhone Kupi AI MP4 to each app, swap the sound inside the app if you want a platform's own version, and add the AI label on each one. Some apps compress video differently, so preview it after upload. Save the file within 24 hours of rendering.
Is the iPhone Kupi sound free to use in my video?
Using the song inside a platform's own sound library on a personal account is how most people post it, but it is not licensed for ads. The iPhone Kupi AI video includes the original track by SABI and MIA BOYKA, and you should keep it organic. If a platform mutes or removes the sound, replace it with another available track.
Will an AI-labeled video get fewer views?
Nobody outside the platforms can say, and any figure you read about this is unverified. The practical reason to add the label is that platforms ask for it on AI-generated content, and a missing label risks removal. Use the label option the app offers for your iPhone Kupi AI video and check the current rules.
Should I tag Win William when I post?
You may tag the creator or mention the sound if you want to point to where the trend started, but tagging does not mean he endorses your video, and he has no connection to iPhone Kupi AI. Many people name the sound instead. Keep any text clear that your clip is a fan-made AI version and not the original.
