How to Play Zoetrope Vinyl Records

Got a zoetrope vinyl from Blood Records, Vinyl Moon, or another label? Here's everything you need to know to see the animation come to life.

What is a zoetrope record?

A zoetrope vinyl has a pattern printed on its surface — usually a series of slightly different images arranged in a circle. When the record spins on a turntable and you view it under a strobe light at the right frequency, the images blend together into a smooth animation. It's the same optical illusion behind the 19th-century zoetrope toy.

Many artists and labels release limited edition zoetrope picture discs. Blood Records is one of the most well-known, regularly dropping zoetrope vinyl editions that animate album artwork right on the record.

What you need

Just two things:

A turntable — any standard turntable that plays at 33⅓, 45, or 78 RPM.

A strobe light — or just your iPhone. The Zoetrope It app turns your flashlight into a precision strobe tuned to the exact frequency your record needs.

How to use it

Step 1

Put your zoetrope vinyl on the turntable and let it spin at the correct speed (usually 33⅓ RPM).

Step 2

Open Zoetrope It and turn on the strobe. Point your phone's flashlight at the spinning record. Darken the room for the best effect.

Step 3

Watch it come to life. The app starts with settings that work for most zoetrope vinyls. If the animation doesn't look quite right, use the fine adjust slider until it locks in.

Tip: If the animation drifts slowly forward or backward, nudge the fine adjust slider. When it's perfectly synced, the animation appears frozen in motion. For best results, dim the lights or use the app in a dark room.

The math behind it

The strobe frequency is calculated from your turntable speed and the number of animation frames:

Frequency = (RPM ÷ 60) × Frames
Result in Hz (flashes per second)

Here are some common combinations:

RPMFramesFrequency
33⅓3620.0 Hz
33⅓4022.2 Hz
33⅓4826.7 Hz
453627.0 Hz
454030.0 Hz
454836.0 Hz
Don't want to do the math? The Zoetrope It app handles all of this for you — just pick your RPM and frame count.

Recording the animation

Want to share the effect on video? Zoetrope It has a camera mode that locks your iPhone's frame rate to match the record's animation. The camera shutter acts as the strobe, capturing the zoetrope effect directly — no flickering, no strobe needed.

Frequently asked questions

Can I use any phone flashlight app?

Regular flashlight apps don't strobe at precise frequencies. Zoetrope It uses a hardware-level strobe synced to your exact turntable speed and frame count, which is what makes the animation visible.

Why can't I see the animation?

The most common issues: wrong frame count (recount carefully), room isn't dark enough, or the strobe needs fine-tuning. Use the fine adjust slider to nudge the frequency until the animation locks in.

Does it work with any zoetrope vinyl?

Yes — it works with any zoetrope picture disc regardless of label, including releases from Blood Records, Vinyl Moon, and indie pressings. Just match the RPM and frame count.

What's the photosensitivity warning about?

Strobe lights can trigger seizures in people with photosensitive epilepsy. The app shows a warning on first launch. If you or anyone nearby is sensitive to flashing lights, use the camera mode instead — it doesn't use a visible strobe.

Is the app free?

Zoetrope It is available on the App Store for iPhone.
