To post your toc toc video on TikTok, Reels or Shorts, upload the MP4 from Toc Toc Dance AI as it is: it is already vertical 9:16, it runs 11 to 15 seconds, it has the trend sound mixed in and it carries no watermark. The only decisions left are whether to keep that sound or swap it in the app, what to write in the caption, and whether to tag a friend.
Key takeaways
- The file is ready to post. You do not need to add the trend sound in TikTok, though you can swap it there.
- Keep the built-in sound for the cleanest match to the trend. Swap it when you want a particular TikTok sound page, or when an app mutes or flags the audio.
- The door version works as a tag-a-friend post: the caption does the tagging and the video does the joke.
- Leave the video in 9:16. Eleven seconds is short enough to loop, so do not pad it.
What is already in the toc toc video file?
Each Toc Toc Dance AI download is an MP4 with the picture, the trend sound and nothing laid over it. That means the dance, the room and your face come from the render, and the audio is a cut of the song, mixed in after the video was made.
The details that matter when you post:
- Sound. "son original - NLBZ", the most used TikTok sound for the trend, found under about 36,000 videos when we checked on 25 October 2026. It is a cut of "Toc toc", a 2015 French party song by Patrick Sébastien.
- Format. 9:16 by default. The tool can also output 1:1 and 16:9, but the vertical file is the one for TikTok, Reels and Shorts.
- Length. 11 seconds for the solo templates and 15 seconds for the hallway and trio templates, because each follows the length of the clip it was measured from.
- No watermark. Nothing is stamped on the picture, so there is nothing to crop out.
- File name. The download is called toc-toc.mp4, which you can rename.
The file is yours to post. Toc Toc Dance AI is an independent tool and is not affiliated with Patrick Sébastien, his labels, the Jean Phil account, TikTok or ByteDance, and the sound belongs to its rights holders, which is why the next section is worth reading.
Should I keep the trend sound or swap it in the app?
Keep the built-in sound if you want the post to match the dance beat for beat, and swap it in the app if you want your post attached to a specific sound page. Both are fine, and you can try one and then the other.
The file's sound was cut to fit the picture, so the hops, the knocks and the freeze land where they should. If you replace the audio with another cut of the song, the timing may not line up, and the comedy of the dance depends on it. In that case, line up the first knock with the first beat of the new sound, and check the freeze at the end.
Reasons to swap:
- You want the trend's sound page. TikTok groups videos by the sound they use, and a post with the "son original - NLBZ" sound from the sound picker appears on that sound's page. A video with the same audio baked into the file is not necessarily linked to it. If being listed there matters to you, add the sound in the app and lower or mute the video's own audio.
- An app mutes or flags the audio. The sound is a cut of a copyrighted song, and rights holders can ask us to remove it. If an app drops the audio on your upload, pick the sound from the app's own library instead, or from the platform's licensed music.
- You are posting on Reels or Shorts and want that app's version of the sound. Each app has its own audio library, and the available cuts differ.
Reasons to keep it:
- It already fits the clip, so you do nothing.
- You avoid timing drift from a second edit.
- You can post the same file on all three platforms in a few minutes.
If you do nothing, you still have a complete post. Swapping is an option, not a requirement.
How do I post it on TikTok, Reels and Shorts?
Open each app, create a new post from the camera roll, pick the MP4 and publish it with your caption. The steps are close to identical across the three platforms.
- Save the file to your phone. Download the MP4 from Toc Toc Dance AI and keep it in your camera roll.
- Start a new post. On TikTok choose upload, on Instagram choose a new Reel, on YouTube choose a new Short, and pick the video.
- Leave the picture alone. Do not crop, zoom or add a second clip over it. A 9:16 file already fills the screen.
- Decide on the sound. Keep the original audio, or follow the swap steps above.
- Add a caption and the cover frame. Pick a frame from the stare or the ta-da, when the face and costume are clearest.
- Mark it as AI-generated if the app asks. The video is an AI render of you. Each app has its own label for synthetic content, and using it is the honest default.
- Publish.
You can post one file on all three platforms. If you want to avoid the same caption three times, change the wording slightly for each. The file does not change.
What caption works for a toc toc video?
A short caption that names the joke works best, and the dance itself is the hook. The toc toc videos on TikTok that travel are the ones where the caption is as flat as the dancer's face.
Some patterns that fit the deadpan tone:
- A flat label. One plain line that says what you did, such as the name of the dance, with no exclamation marks.
- A situation. "Me when someone knocks" style captions, because the dance is a knock-knock joke.
- A template note. Naming the look, like the blond bob, helps people searching for that version.
- A search phrase or two. Words people actually use: toc toc dance, toc toc trend, toc toc AI.
Keep hashtags few and relevant. The trend is under a month old, so tags are still shifting; look at what the top posts under the sound are using on the day you post, and copy the pattern and not a fixed list.
One caution on captions: do not paste the song's lyrics. They are copyrighted, and a caption does not need them. The title and the line people search, "Toc toc, on frappe à ma porte", are enough if you want to reference the song.
How does the tag-a-friend door video work?
The door version is a two-person joke and the caption is half of it. Someone in a blond bob opens a front door and a costumed guest hops in straight at the camera. People post it with a line that dares a friend, and the comments fill with tags. Several US accounts posted versions from 14 October 2026, captioned with lines like "You can name one friend, can't you?".
Front Door Parade makes that format from two photos: yours as the person at the door and your friend's as the guest. The 11-second clip already contains the entrance, so the caption only has to supply the tag.
How to post it:
- Write the dare in the caption. A single line that asks a friend to show up, in the same flat tone as the video.
- Tag the friend whose photo you used. They are in the video, so they will want to see it. Only use a photo of an adult who agreed to be in it.
- Tag in the comments as well if you like. Some people split the tags between caption and comments to keep the caption readable.
- Reply to comments with another render. If three friends ask to be next, the next video is one upload each away.
Because the door template is directed in words, entrances can vary between renders. If the first one misses, render again before posting. The common failures post covers what to do when the entrance goes sideways. You can also use Side by Side for a duet that does not depend on an entrance.
What size and length should a toc toc post be?
Post it as 9:16 and at its natural length of 11 to 15 seconds, and do not stretch it. Vertical full-screen is the format of TikTok, Reels and Shorts, and the file already fits it, so no black bars or cropping are needed.
Length is where people overthink. An 11-second clip is well under the limit of all three platforms, and a short clip is easy to watch twice. Adding a slow intro or an end card dilutes the format. If you want more, post a second template as its own video instead of stitching two together.
On resolution, Standard 720p looks fine on a phone. Choose a higher resolution only when the face is small in frame, as in the hallway and trio templates, where 1080p is available on the Pro and Ultra tiers. Higher resolution costs more credits, and the pricing page lists each option.
What to avoid:
- Re-exporting through an editing app at a lower quality.
- Adding captions across the face during the stare beat.
- Cropping a 9:16 file to square or the wrong way round.
What if the video is not ready to post yet?
If the dance looks off, fix the render and not the caption. A drifting face, a wrong outfit or a missed beat will not be saved by a good sound or a clever tag.
Most problems are solved by a different photo, another template, a higher tier or a re-render. A failed or blocked render returns its credits automatically, and a render that finishes but looks wrong counts as a completed video. The Single pack is $6.99 for 10 credits, enough for one Standard 720p video, and credit packs are final sale.
If you are not sure which template to use, Blond Bob Solo is the classic look, Come As You Are keeps your own clothes, and Hallway Rush is the 15-second dorm corridor. To understand why the clip looks the way it does, see why copied toc toc prompts fail. To make one, go to the generator.
Frequently asked questions
Does the toc toc video have the sound already?
Yes. Every Toc Toc Dance AI video has the trend sound, "son original - NLBZ", mixed in after rendering, so you can post the MP4 as it is. You can still swap it for a sound from TikTok, Reels or Shorts inside the app.
What size should a toc toc video be for TikTok and Reels?
Use 9:16 vertical, the default Toc Toc Dance AI format. The solo templates run 11 seconds and the hallway and trio templates 15 seconds, well within the limits of TikTok, Reels and Shorts. The file has no watermark, so you do not need to crop it.
How do I make the tag-a-friend toc toc door video?
Pick Front Door Parade on Toc Toc Dance AI, add your photo as the person at the door and your friend's photo as the guest, and generate. Post the 11-second video with a caption that dares your friend and tag them. Use photos of adults who agreed.
Can I post the same toc toc video on TikTok, Reels and Shorts?
Yes. The vertical MP4 from Toc Toc Dance AI works on all three. Change the caption slightly for each app, mark it as AI-generated if the app offers a label, and swap the sound in-app only if you want to join a specific sound page.
