How to Make a Check One Check Two AI Video, Step by Step
Updated October 22, 2026
Quick answer
Sign in to CheckOneCheck, upload one clear front-facing photo, pick 480p or 720p, buy enough credits and generate. The video comes out silent — add "Check One, Check Two" from the platform's audio library when you post, and line the opening "yo" up with the first frame.
What You Need
- One photo — JPG, PNG or WebP up to 10 MB. Use a sharp, front-facing photo of yourself or a consenting adult; waist-up framing works best because the arms carry the gestures.
- A CheckOneCheck account — sign-in is required to generate; guest sessions are off.
- Credits: each 11-second video uses 374 at 480p or 836 at 720p. $1 = 100 credits; one-time packs start at $5.
Step 1 — Pick the Photo
Use a sharp, well-lit, front-facing photo — eyes open and visible, no sunglasses or heavy filters. The face should take up a good part of the frame.
Waist-up framing is ideal because the reference keeps the arms for the nod and the point. Full-body works too; group shots don't.
Step 2 — The Poolside Scene
There is one scene at launch. Your photo replaces the centered adult; the lip timing, head nod and hand gestures are kept from the reference.
| Scene | What it does | Best photo | Credits |
|---|---|---|---|
| Poolside | Your photo becomes the rapping subject on a sunlit poolside terrace | Front-facing, waist-up | 374 / 836 |
Step 3 — Generate in the Studio
Open the studio, sign in, drop your photo in, pick 480p or 720p and hit generate. Follow the task status — the video lands in your history when it is ready.
When the video is ready, download the MP4. Videos are created private — nothing is posted to a public gallery.
Step 4 — Download and Add the Sound
The MP4 comes out silent on purpose — no song is baked in. To post with the original sound, upload the video to TikTok or Reels, tap "Add sound" and search for "Check One Check Two" — pick the sound most posts in the trend use.
This is the important step: align the sound so the opening "yo" lands on the first frame of your clip. In the TikTok editor, drag the sound until its first beat sits at time 0 — that is what makes the lip-sync read as real.
Step 5 — Post Responsibly
- Mark the video as AI-generated when the platform asks.
- Only use photos of yourself or of people who agreed.
- Don't post real people without their OK — and never photos of minors or public figures.
Photo Do's and Don'ts
Do
- Use a sharp, front-facing photo with even light.
- Fill a good part of the frame with the face; waist-up is ideal.
- Keep the expression simple — eyes open, slight smile.
Don't
- Sunglasses, masks or heavy beauty filters.
- Strong side profiles or a face smaller than a thumbnail.
- Motion blur, harsh shadows or extreme angles — and group shots.
Troubleshooting
The face looks off in a few frames
A sharper, more front-facing photo usually fixes it. Faces that are small in the source photo come out less cleanly — crop in tighter and retry.
The mouth doesn't look synced to the song
The lip timing follows the reference clip. Make sure you added the sound inside TikTok or Reels and aligned the opening "yo" with the first frame — a sound that starts a beat late will read as out of sync.
The generation is taking a while
Processing time varies. Follow the task status in the studio — the clip lands in your history when it is ready.
The result came out blurry
Start from a higher-resolution photo with the face well lit and unobstructed, then run it again.
