1080×1920 · 60 fps

Every impact lands on the beat.

Drop a track. Zictovid turns it into a vertical 3D video where every bounce hits exactly on the beat. 1080×1920, 60 fps, ready for TikTok.

The principle

Sync is not a promise. It is a construction.

Simulating a ball and hoping it lands on the beat does not work: the moment of contact depends on the time step, and nothing constrains it. Zictovid starts from the beat times and derives the geometry of the level from them. The trajectory is solved backwards.

01

We listen to the track

The analysis picks up onsets band by band — lows, mids, highs — and turns them into a map of beats.

02

We compute the trajectory

Each beat is snapped to the nearest frame, then the parabola between two impacts is solved in closed form. No simulation.

03

We build and render

Platforms land where the ball passes, the 3D scene is built, the render comes out natively vertical.

Why it holds

Four properties simulation cannot give you.

Exact by construction

The maximum error is half a frame — 8.3 ms at 60 fps. The threshold of perception sits around 20 ms.

Reproducible to the bit

Same track, same video. The engine uses no unseeded randomness and no physics iteration.

Musical, not metronomic

A heavy kick throws the ball high, a hi-hat gives a small bounce. Beat strength drives the height.

Natively vertical

1080×1920 at 60 fps, the format of TikTok, Reels and Shorts. No cropping, no black bars.

Gallery

Videos, not mockups.

Every thumbnail is a real render from the engine.

Pricing

A clear quota, because rendering costs GPU time.

No unlimited plan: one video takes minutes of graphics card, and promising infinity would be lying. You know exactly what you are buying.

Feedback

What the eye notices first.

The ball hits dead on the beat. You see it straight away, and that is what holds your eye.

Frequently asked

What people ask before trying it.

How can the video be exactly in sync with the music?

The engine does not simulate a ball and hope it lands on the beat. It starts from the beat times found in the track, snaps each one to the nearest frame, then solves the parabola between two impacts in closed form. The geometry of the level is derived from the trajectory, not the other way round. The maximum error is therefore half a frame — 8.3 ms at 60 fps, below the threshold of perception, which sits around 20 ms.

Does the same track always give the same video?

Yes, to the bit. The engine uses no unseeded randomness and no physics iteration: the same input bytes produce the same video. That is what lets you iterate on an edit without watching the sync shift between renders.

Which files can I upload, and what is the size limit?

An MP3 or a WAV, up to 40 MB. The accepted length depends on the plan: 30 seconds on the free plan, up to 180 seconds on the widest one. It is the length, more than the number of videos, that bounds a plan — rendering is paid by the GPU-second.

What is the output format?

1080×1920 at 60 frames per second, natively vertical — the format of TikTok, Reels and Shorts. Nothing to crop before posting, no black bars.

Is there a free plan?

Yes: 3 videos per month, 30 seconds max, with the zictovid watermark, and no card required. The Creator plan, at €19 per month, goes up to 30 videos and removes the forced watermark.

Why is there no unlimited plan?

Because one video burns real minutes of graphics card. Promising infinity would mean either lying, or quietly throttling the first heavy user. A published quota says exactly what you are buying.

Can I post the video on TikTok, Instagram or YouTube?

The video is yours, with no restriction on our side. You do remain responsible for the rights to the music you upload: a commercial track stays subject to the rules of whichever platform you post on. Zictovid provides no music licence.

Do I need to install anything?

No. Everything happens in the browser: you drop a track, the render runs on our machines, you collect an MP4. No editing software, no graphics card on your side.
