The growing up beside you trend is a 7 second clip that cuts from an older photo of two people to a newer one, with each person's age above their head. The growing up beside you AI video maker on videosi builds it from one photo of the two of you, by guessing a younger snapshot from four years earlier and then cutting to your photo as it is now. That younger snapshot is generated by AI; it is not a real photo of you from four years ago.
This guide goes past the basics and answers what people ask once they start making their own: why the caption and the ages work, how to choose the photo, how the younger half is guessed, how it differs from an aging filter, and what to check before posting.
Key takeaways
- You need one photo of exactly two adults. The younger snapshot is an AI guess, not a real archive picture.
- Both people must be adults, and the age boxes start at 22, so even the younger half stays at 18 or over.
- The first half is always four years lower than the numbers you type, and the cut lands at 2.2 seconds.
- A 7 second Standard 720p clip costs 10 credits, and the Single pack is $6.90 for 10 credits.
- Check the ages and caption before you post, and label the video as AI generated.

Why do the caption and the two ages work so well?
The clip tells a whole story in two lines of text and two small numbers. The caption first reads "looks like I'm growing" and, after the cut, completes to "I'm growing up beside you". The sentence is unfinished until the second photo arrives, so viewers wait for the cut.
The ages do the rest. Seeing 19 and 26 become 23 and 30 tells you exactly how much time passed and that the two people stayed side by side while it did. The edit is used for couples, best friends, siblings and long marriages, and the format is simple enough that anyone with two photos can copy it.
That is also why videosi keeps the text locked to the original structure. The trend page rebuilds the caption change and the two numbers, so the clip reads the same way as the posts people already know.
What happens second by second in the clip?
The video runs 7 seconds and has four beats. From 0 to 2.2 seconds you see the earlier snapshot: the two people standing close, facing the lens, the first caption at the top and two small ages beside their heads. At 2.2 seconds there is one hard cut to the newer photo, the same pair in the same close two-shot, in different clothes.
From 2.2 to 5 seconds the caption completes and both ages are four higher than before. From 5 to 7 seconds the two stay in frame with a slight sway and soft smiles while the sound plays out. The cut is a real cut, not a slow fade, and that hard edge is the part viewers recognise.
How should you pick the photo?
Use one sharp photo with exactly two people, standing shoulder to shoulder and facing the camera. Both faces should be large, clearly visible and evenly lit. Crop out anyone else, because the clip has room for two faces only.
Avoid sunglasses and hats. When both faces are visible, the younger snapshot looks like the same two people instead of two strangers. Small, dark or crowded photos are the most common reason a result does not look like you, so spend a minute choosing the best frame from your camera roll.
Your photo is the only source for both faces, hair, skin tone and clothes in the "now" half. Nothing from the trend's original clip remains, so what you upload is what you see.
Should you upload one photo or two?
Both work. The simplest route is one photo of the two of you together. If you have no good shot of the pair, you can add each person as a separate photo instead: photo 1 is you and photo 2 is your partner, friend or sibling.
Each face is locked to its own photo, so the first person stays the first person and the second stays the second. With two separate photos, pick two that match in light and sharpness, because a bright portrait next to a dim one can make the pair look mismatched in the final frame.
How does the AI guess the younger snapshot?
The model reads your photo and rebuilds the same two people exactly four years younger, as in a casual phone photo from back then. The skin is a little younger, the hair slightly different, the clothes simpler, the background plain and indoors. The two stand close, smile, and one hand is raised in a small wave.
It is a guess, not a recovery. The model does not know your real old pictures, so the younger snapshot will not match the photos in your camera roll. Think of it as a plausible earlier version of the pair. If you want to post it, do not present that first half as a real archive photo.
Behind the scenes, the page uses Seedance with a 7 second reference clip of the trend, which supplies the framing, the cut timing and the caption timing. Your photo supplies the people.
How do the ages work, and why do they start at 22?
You can type your age now and the other person's age now. The numbers appear above each head in the "now" half, and the first half shows the same people exactly four years lower. For example, 30 becomes 26 in the earlier snapshot. Leave the boxes empty and the clip uses 28 and 30, with 24 and 26 in the first half.
The boxes accept 22 to 90. The lower limit is deliberate. Both people must be adults in every frame, and a four year step back from 22 lands on 18, so the younger half never drops below adulthood. Photos of children are not supported.
The numbers are part of the joke, so type the real ones. AI drawn digits can still come out wrong, which is why the page tells you to check them before you share.
How is this different from the age filter?
The aging filter shows one person turning old, with numbers that climb up to 80. The growing up beside you clip shows two people in an older and a newer photo with their real ages, and it goes only four years back. One is about a distant future, the other about the time you have already shared.
If you want the older-face version, the age filter AI page makes it from a single selfie. If you want the couple or friendship version, use the growing up beside you page with a photo of two.
What if your partner has no photo with you?
This is the case the AI version was built for. The real trend needs two matching photos taken years apart, and many pairs only have the new one. With videosi you need only the newer photo, and the earlier half is generated.
If you have no photo of the two of you at all, upload one photo each, as described above. Choose shots with similar light, ask your partner for a clear front facing picture, and type both ages. The result still opens on a younger pair and cuts to now.
Who can be the second person?
Any adult: a partner, friend, sibling or parent. The trend itself is not limited to couples, and best friend and sibling versions are common.
The only firm rule is that people shown must be adults. The page asks for ages from 22 up, and it does not support photos of children or make an older version of the pair.
What can you do when the result looks off?
First check the photo: more than two faces, a very small face, heavy shadows or a hat are the usual causes. Swap in a sharper picture and try again. Second, check the ages and caption in the finished clip, since they are drawn by AI and have not been fully tested yet.
A failed or timed out render returns its credits automatically, so a technical failure does not cost you. The clip comes with the trend's original sound and no watermark, so there is nothing to clean up afterwards.
On cost, a 7 second Standard 720p clip is 10 credits and the Single pack is $6.90 for 10 credits, so one clip is one Single pack. Larger packs and plans lower the price per video. You can start from the growing up beside you page and see the exact price before you generate.
What should you do before posting?
Watch the whole clip once with sound. Check that both numbers are right and that the caption reads "looks like I'm growing" and then "I'm growing up beside you". Confirm that each face looks like the right person.
Then label the video as AI generated where TikTok or Instagram ask for it, since it is realistic AI video. Remember that the first half is an AI guess of how you looked four years ago, so keep it clear that it is not an archive photo. Tag your person, and keep the text simple. The format works because it is short, honest about time and easy to read in two seconds.
