See it on the real screen
Judge colour, contrast, and framing on the actual iPhone your audience watches on — live, while you edit, with no render or transfer.
See it on the real screen
Your editing monitor is not the screen your audience uses. A laptop or a calibrated grading display shows your edit very differently from a phone held at arm's length in daylight — different brightness, different contrast, a different aspect ratio, and a much smaller frame. PreviewMonitor closes that gap by putting the live picture on an actual iPhone, right next to you, while you work.
That's the whole idea: stop guessing how the edit will land on a phone, and just look at one.
Why a real device matters
When you're cutting content for TikTok, Reels, or Shorts, the finished video is almost always watched on a phone. Things that look fine on a big desktop monitor can fall apart on a handheld screen:
- Brightness and contrast read differently on a phone, especially in a bright room. Shadows that look rich on your monitor can crush to black on a phone.
- Framing changes when the picture is small. A subject that fills your editing monitor can feel lost on a phone, and fine detail or text can become unreadable.
- Motion feels different at phone size and brightness.
Seeing the edit on the device it's made for lets you make those calls with your eyes instead of from memory.
No render, no transfer
The usual way to check an edit on your phone is slow: export a draft, AirDrop or upload it, wait, watch it, go back, change something, and do it all again. PreviewMonitor skips that loop entirely — the picture streams live from Premiere Pro or After Effects to your iPhone as you scrub and play. Change a grade or a cut and you see it on the phone immediately.
Inspect the detail
Because it's a real, full-resolution picture on the phone, you can lean in:
- Pinch to zoom right into the frame to check edges, text legibility, compression artifacts, or a tricky bit of keying — further than the Photos app normally lets you zoom. See Monitor a Clip for the same controls offline.
- Grab a full-resolution still to your Photos library for a before-and-after comparison, or to keep a reference frame. See Saving a framed still.
- Add a social safe-zone overlay to see colour and framing inside the real platform chrome at the same time.
PreviewMonitor shows your picture on the iPhone's own display — it doesn't re-grade, tone-map, or "correct" the image. What you see is your frames, shown on a real phone screen. That's exactly the point: you're judging the picture on the kind of device your audience will actually use, not a simulation of one.
Get the cleanest picture
So the picture on the phone is a faithful reference, keep the stream healthy and high-quality:
- Use a strong connection and a sensible Resolution Limit so what you're judging isn't softened by a weak network. See How networking works.
- Prefer H.265 on a modern iPhone for the best quality at a given bandwidth — see Encoding settings.
- Keep an eye on the live HUD if the picture ever looks worse than it should; it tells you whether the network is the cause.
