To post a shaking head video, download the 10-second MP4 within 24 hours, upload it as it is in 9:16 to TikTok, Instagram Reels or YouTube Shorts, keep the original sound that is already in the file, turn on the AI-generated content label where the app asks for it, and write a one-line caption that tells a small joke about a test, a computer or a bad day. AI Shaking Head produces the file without a watermark, so there is nothing to crop or cover.
Key takeaways
- Render in 9:16 for TikTok, Reels and Shorts. AI Shaking Head also offers 1:1 and 16:9, but vertical is the format the trend lives in.
- The trend's original sound is already added to the finished file, so leave your editor's music alone and upload the clip as it is.
- The caption formula is a short setup about a test, a Chromebook or a computer shutting off, followed by the clip as the punchline.
- Label the clip as AI-generated where the app offers the option. Each app has its own toggle, and the wording changes, so check the screen in the app you use.
- Finished files stay downloadable for 24 hours. Save the MP4 right away.
- AI Shaking Head is independent and not affiliated with TikTok, CapCut or ByteDance.

Which ratio and resolution should I pick before I render?
Pick the ratio before you render, because it sets the frame the whole clip is composed in. For TikTok, Instagram Reels and YouTube Shorts choose 9:16. For a square feed post choose 1:1. Use 16:9 only if the clip will sit in a wide video or a website. You can render the same photo again in another ratio, but that spends credits, so decide where it is going first.
For resolution, a Standard video at 720p costs 10 credits and is good enough for most phone screens. Higher tiers cost more: Fast at 720p is 17 credits, Pro at 720p is 20 and Ultra at 720p is 37. If the clip is for a post you care about, a higher tier holds the face and the eye snap more closely, which matters because the whole joke is the face. If you are only testing a photo, Standard at 480p costs 5 credits.
There is no free tier. The smallest pack, Single, is $6.99 for 10 credits, enough for one Standard 720p video. Credits never expire, and a render that fails returns its credits. The pricing page lists every pack.
What is already inside the video file?
The file already holds the picture and the trend's original sound. AI Shaking Head renders a 10-second clip built around three loops of the trend: a smug squint with the eyes shut, a snap where the eyes pop wide open, a quick wide-eyed side-to-side shake, and a return to the squint. Each loop is about 3.6 seconds. After the picture is rendered, the original sound is added, so the file you download is complete.
There is no watermark on the finished clip. A watermark would look messy on a post. You can upload the MP4 as it is.
Your download is available for 24 hours. Your uploaded photo is deleted within 24 hours. So after a render finishes, save the file to your phone or computer, and keep a copy in case you want to post it again later or on another app.
Should I keep the original sound or choose a sound in the app?
Keep the sound that is already in the file for a first post. The trend is the sound and the face together: the squint, the snap and the shake are timed to the clip's original audio, so replacing it with a different track breaks the joke. Uploading the MP4 as it is keeps the beats lined up.
On TikTok, the original sound in the viral clip is listed as "original sound - I.d.k NAME". On 2026-10-29 about 697 videos had used it. If you want your clip tied to that sound page, you can look for the sound in the app and use it there, but your own file already carries the audio, so you do not need it to get the effect. Whether a given app lets you attach an existing sound to an uploaded file depends on the app and the version, so treat that as optional.
Two cautions:
- Do not stack a second sound on top. Two tracks at once muddy the beat.
- If an app mutes or replaces audio for any reason, play your clip back before you post it to check that the sound survived the upload.
The original sound belongs to its creator, so follow each app's rules on sounds.
How do I write a caption that sells the joke?
Write the caption as a setup and let the clip be the punchline. The original post framed it as how a friend, "hb" for homeboy, acts after restarting a test on a Chromebook that had 95% of the poster's grade on it. A remake used "how bro looks when he turns off your computer when you are mid test that is 75%". The caption is a small piece of school humour, and the face does the rest.
Here is the formula:
How [person] acts when [annoying thing happened] on [device or situation].
The annoying thing should be small, specific and relatable. A few shapes that fit the trend:
- How my brother acts when he restarts my Chromebook mid-test.
- How my cat looks when I say the test is worth half my grade.
- Me when the teacher says "that was on the study guide".
- How my dog acts when I say we are not going to the park.
- Me after I get an answer right and nobody noticed.
Keep these rules in mind:
- Name the subject in the clip. If the photo is your cat, say "my cat". The joke lands because the face is real.
- Keep it short. One line. The clip is 10 seconds, and a caption that takes longer to read than the video is a miss.
- Use a real number when it is funny. A test worth 95% or 75% of a grade is a big part of why the original worked. Make it your own figure.
- Do not explain the meme. People who know the trend get it, and people who do not will ask in the comments.
Which hashtags should I use?
Use a small set of hashtags that match what people already search. The ones that the trend's remakes use are #shakingheadtrend, #shakinghead and #funnyedit. The original used #relateable, #school, #hb, #dance and #funny. A mix of two or three trend tags and one or two topic tags is enough.
A simple pattern:
- One or two trend tags: #shakingheadtrend and #shakinghead
- One format tag: #funnyedit
- One topic tag for your subject, such as your pet or the school joke
Do not copy a long block of unrelated hashtags. Tags that do not match the clip do not help, and a pile of them can look like spam. Put the tags in the caption or the first comment, depending on how your feed usually looks, and keep the caption itself readable.
Hashtag use changes quickly, and the trend was only about a week old when this was written. Check what is showing under the tag the day you post, and adjust.
How do I label AI-generated content on each app?
Label the clip as AI-generated where the app offers a toggle. The clip is made with a video model from a photo, and the major apps ask creators to disclose realistic AI-generated video. TikTok has a setting for AI-generated content in the post options. Instagram and YouTube have their own disclosure options for altered or synthetic content. The names and the screens change from time to time, so look for the option in the post settings before you publish and follow the wording on screen.
A few practical points:
- The label is about honesty with viewers. A shaking head video of a cat is clearly a joke, and a label does not spoil it.
- A label may be needed if the clip shows a person who could be mistaken for real, so be most careful with selfie and baby clips.
- Do not remove a label an app has added.
- Read the app's current rules before you post, because they change.
A word on privacy and consent. Use a photo of your own pet, your own face or your own child. Baby Giggle is for a parent or legal guardian to use with their own child, fully clothed. Do not make clips of someone who has not agreed, and do not post a baby clip if you would not want it shared widely. A public post is public.
How should I time the post?
Post soon, and do not wait for a perfect moment. This trend started in the US in October 2026, with the original posted on 2026-10-20 and remakes appearing from 2026-10-21. Remakes with cats, calves, kids and others followed within days. Trends like this move fast, so an early post is more useful than a polished late one.
Some practical timing notes:
- The render takes about three to four minutes, so you can make a clip, check it and post it within a short session.
- School humour fits the school week and evenings in the US, since the trend's audience is mostly US teens and students. That is a reasonable guess from the topic and not a measured statistic.
- If you have several clips, post one, see how it does, and then post a different subject instead of the same joke three times.
- Remember the 24-hour download window. If you want to post tomorrow, download the file today.

What should I not post?
Do not post anything that the clip is not. A shaking head video is a short joke, and a few things turn it into a problem.
- Someone else's face without their consent. Use your own photo or one you have the right to use.
- A public figure or a famous person. Keep it to pets, family you have permission for and yourself.
- A child that is not yours. Baby Giggle is only for a parent or legal guardian uploading a photo of their own child, fully clothed.
- A clip that claims to be real footage. Label it as AI-generated and let people enjoy it as a joke.
- A caption that makes fun of a real person. The school and Chromebook joke works because it is about a situation, not a named individual.
The acceptable use policy lists what is allowed on the site.
What if the clip is not ready to post yet?
If the clip is off, fix the photo, the template or the tier before you spend credits again. A render that fails returns its credits automatically, but a finished clip that looks wrong counts as a success and there are no refunds, so a short check first is cheaper than another render.
To get a better result:
- Use a sharp, front-facing photo with both eyes visible.
- Pick the template made for your subject. Smug Cat, Wide-Eyed Kitten, Dog Head Shake, Farm Calf, Any Pet Any Place, Selfie Head Shake and Baby Giggle are all on the templates page.
- If the face changes during the shake, move up a tier.

Frequently asked questions
What size should a shaking head video be for TikTok and Reels?
AI Shaking Head renders in 9:16, which is the right size for TikTok, Instagram Reels and YouTube Shorts. It also offers 1:1 for feed posts and 16:9 for wide videos. Pick the ratio before you render, because changing it later means a new render.
Does the video already have the original sound?
Yes. AI Shaking Head adds the trend's original sound to the finished 10-second MP4 after rendering, so you can upload the file as it is. Do not add a second track on top, and play the clip back after upload to confirm the sound came through.
What hashtags go with a shaking head post?
AI Shaking Head users commonly pair the clip with #shakingheadtrend, #shakinghead and #funnyedit, then add one tag for the subject. The original clip used #relateable, #school, #hb, #dance and #funny. Check what is showing under the tags the day you post.
Do I need to label the video as AI-generated?
AI Shaking Head makes the clip with a video model, so it is best to turn on the AI-generated content label where TikTok, Instagram or YouTube offers one. The screens and the rules change, so follow the wording in the app when you post. A label does not spoil a joke.
How long can I download my video?
AI Shaking Head keeps finished files available for 24 hours, and uploaded photos are deleted within 24 hours. Save the MP4 to your device as soon as the render finishes, which takes about three to four minutes. A render that fails returns its credits.
