TirkyMag™

The magazine that changed everything.

A rotary prism camera that stops

Every high-speed camera wastes film. The physics of rotary prism systems demand acceleration at the start and deceleration at the end of every take — unusable footage that goes straight to the bin.

TirkyMag™ changes that. Our patent-pending technology allows the K65K to stop mid-take — something no other rotary prism camera has ever done. When the director calls cut, the camera actually stops. No wasted acceleration. No wasted deceleration. Just the footage you need.

Save film. Save time. Shoot more.

At 800 fps in 6-perf mode, K65K burns through film at an extraordinary rate. Every second of acceleration wastes meters of precious negative. Every deceleration does the same.

TirkyMag™ recovers those tails. The system captures the acceleration and deceleration phases and returns them to usable stock. On a typical high-speed shoot, that's up to 56 meters saved per take — real budget that stays in your pocket, not on the cutting room floor.

But the savings go beyond film stock. With tail recovery, you fit more takes on a single roll. Fewer magazine changes mean less downtime, fewer interruptions, and more momentum on set. When you're shooting a complex high-speed sequence, every reload costs time — time you could spend capturing the shot.

2000 feet. Double the runtime.

The original K65K magazine held 1000 feet of 65mm negative — already generous by high-speed standards. TirkyMag™ doubles that to 2000 feet, giving you extended takes without magazine changes.

For complex high-speed sequences that demand multiple passes or extended run times, this isn't a luxury — it's a necessity. Less downtime for reloads means more time capturing the shot.

Load it like you know it

TirkyMag™ uses the standard Kodak core — the same one you've loaded a thousand times. No proprietary spools, no adapters, no learning curve. If you've ever loaded a film magazine, you already know how to load TirkyMag™.

The intuitive daylight-loading design keeps things simple: open, thread, close. The film path is clear and accessible, with visual guides that make even first-time loads foolproof. On set, simplicity is speed — and TirkyMag™ delivers both.

Intelligent film transport

TirkyMag™ isn't just bigger — it's smarter. The magazine features an advanced film transport system that maintains perfect tension across the entire speed range, from 1 fps to 800 fps. Variable-speed torque motors adjust in real-time, ensuring consistent registration whether you're shooting dialogue or freezing a bullet in flight.

Quick-change design

Despite its increased capacity, TirkyMag™ maintains a practical footprint. The quick-release mechanism allows magazine swaps in under 60 seconds — critical when every minute on set costs money. The light-tight design protects your negative during changes, even in challenging conditions.

Why it matters

High-speed cinematography is expensive. 65mm negative costs more per foot than any other motion picture format. Every meter wasted is money lost — and every magazine change is time lost. TirkyMag™ was designed with one goal: maximize the value of every foot of film and every minute on set.

Combined with K65K's unmatched speed and resolution, TirkyMag™ makes large-format high-speed cinematography not just possible — but practical.
