Questions

Common questions

Is this the same app as Log Cam: Open Gate by RAW Cam?

No. Log Cam: Open Gate by RAW Cam is made by Sebastijan Grabar, who also makes RAW Cam: Open Gate DNG Video. Log Cam: RAW 4K Video Camera is a separate app made by Mehmet Ali Kısacık.

Why do log clips look flat and gray?

Because that is what log does. A log picture profile records a wider range of highlight and shadow detail than a standard profile. The result is a flat, low-contrast picture straight from the camera. You grade the clip afterwards, using the recorded highlight and shadow detail to adjust contrast and color. You do not have to watch a flat picture while you shoot. In the viewfinder’s Look mode, Rec.709 assist gives a normal-looking preview, and an imported .cube LUT previews the graded picture.

Can I record a clip with a LUT applied instead of a flat log clip?

Yes. Import your own .cube LUT into the app, and you can bake it into the recording. The LUT’s look is applied straight to the clip, so it comes out finished without an editing app. Baking is permanent: the clip is saved with the LUT applied. The other mode, monitoring, shows the LUT on screen and keeps the plain log signal in the file. Pick monitoring for anything you intend to grade.

Which log profiles can I shoot in?

Seven: Apple Log, Apple Log 2, S-Log3, Log-C3, V-Log, F-Log and F-Log2. Shoot the curve your grading workflow expects. The conversion you apply later is then the one built for that curve, and not an approximation of it. If none of that means anything to you yet, start with Apple Log.

Can I shoot log if my iPhone does not support Apple Log?

Yes. Apple states that its own Log recording needs an iPhone 15 Pro or later, and Log Cam: RAW 4K Video Camera does not use it. The app applies its own log curves in its own GPU pipeline, and does not ask iOS for Apple’s Log. So the seven profiles, Apple Log included, are not limited to the phones Apple’s Log covers, and the app needs iOS 17.6 or later. Available resolution, frame-rate and bitrate combinations depend on your iPhone model.

Where do my clips go after I stop recording?

You can record to the iPhone or directly to a connected external drive. The gallery shows clips on the iPhone and on the connected drive you select, so you can review them after recording. From there, export a clip to an external SSD, a hard drive, or the Files app.

What happens to my clips if I delete and reinstall the app?

Clips recorded to the iPhone live inside the app and are removed with it, so export the ones you want to keep before you delete the app. Exported copies stay where you saved them, whether that is a connected drive, the Files app, Photos or another device by AirDrop. Clips recorded straight to an external drive stay on that drive.

Can I record straight to an external SSD, or only export to one?

You can do both. Pick an external SSD or hard drive connected directly to the phone as the recording destination, and your clips land on it as you shoot. You can also export clips you already recorded to that drive. No computer is necessary either way. Or export to the Files app and move your clips from there. For longer ProRes sessions, an external drive gives you more room to record.

What ProRes and HEVC recording options does the app offer?

The app records ProRes 422 HQ, ProRes 422 and ProRes 422 LT. It also records 10-bit HEVC in 4:4:4 or 4:2:0, with bitrate presets from 30 to 500 Mbps.

Does it have autofocus, or do I have to focus everything manually?

The app has autofocus and tap to focus. It also has manual ISO, shutter and white balance, for when you do not want the camera to decide. You can pick which of your phone’s lenses records. You can adjust focus, ISO and shutter while you record.

Can I use an external microphone?

Yes. You can record with a Bluetooth, wired or USB microphone connected to your iPhone.
