GyLog

What cameras does GyLog work with?

Two main ways. iPhone's own camera (standalone — the same device shoots video and runs GyLog, no external mount needed). Or most other cameras you already own — mirrorless, DSLR, and other interchangeable-lens bodies — by attaching your phone (iPhone or Android, with GyLog running) firmly to the camera so they share motion. Any secure attachment works: a shoe mount, a rig or cage, a bracket, an arm — whatever holds the phone steady against the camera body. The phone records the motion the camera experiences, and that data drives the stabilization in post. Cameras you can't attach the phone to firmly, or whose timestamps drift unpredictably, will be harder.

Is Gyroflow required?

Yes. Gyroflow is the free, open source stabilizer that uses GyLog's data. You can use Gyroflow Desktop, or a Gyroflow plugin inside supported editing software such as DaVinci Resolve and Adobe Premiere Pro / After Effects. Final Cut Pro uses Gyroflow Toolbox, a paid third-party plugin on the Mac App Store.

What does the audio recording do? iOS only

On iOS, GyLog can record an optional local reference audio track for sync. If timestamps drift between devices, the waveform lets you realign the gyro data with your video. The Android version does not record audio — it logs motion only.

I shoot ProRes RAW with Blackmagic Camera. Do I still need GyLog?

As of the April 2026 update, Blackmagic Camera stabilizes even ProRes RAW on iPhone 17 Pro and later — for most shoots that’s the simpler option. GyLog earns its spot when you want full post-production control over sync, trimming, rolling shutter, smoothness, and crop. If you do shoot with GyLog for later stabilization, set Blackmagic Camera’s Reference Source → Internal to avoid frame-timing issues that can otherwise break stabilization. (Currently tested with iPhone 17 Pro ProRes RAW.)

Can my phone double as an HDMI monitor for my mirrorless camera?

It depends on the camera. Some manufacturers (Sony, for example) offer their own monitor app for iPhone or Android, turning the phone into a wireless preview over Wi-Fi — the same phone can monitor your shot and run GyLog at the same time. For cameras without such an app, iPhone can't act as an HDMI monitor (iOS restricts external HDMI input), but it still works fine as the GyLog logger — just use a separate monitor for framing. On Android, many phones can do both at once: third-party HDMI monitor apps (over USB-C) often run alongside GyLog on the same device. We haven't tested every camera and phone combination, but it works on many.

Is my data private?

Everything stays on your device. GyLog does not upload motion data, audio, or video anywhere.
