Monitor a Clip

Preview a local video or photo on your iPhone — zoom, frame-step, grab stills, and check overlays, with no computer needed.

Monitor a Clip

Monitor a Clip lets you load a video or photo straight from your phone and preview it in the same player you use for live streaming — no Mac, no PC, no Wi-Fi. It's the quickest way to check a render, review footage on a real handheld screen, or test how a clip sits inside a social layout.

Monitor a Clip needs no connection to Premiere Pro or After Effects — it works entirely on your phone.

Loading a clip

On the home screen, find the Monitor a Clip section and pick a video or photo from your phone's library (or from Files). It opens immediately in the player.

What you can do

Once a clip is loaded, you get the full preview toolkit:

  • Pinch to zoom — zoom into any part of the frame to inspect detail, and keep going further than the Photos app normally allows. Double-tap to zoom in and out, and pan around while zoomed.
  • Step frame by frame — use the transport controls to move one frame at a time and check a specific moment.
  • Check the layouts — switch on any layout overlay (TikTok, Reels, Shorts, or Universal Safe Zone) to see how the clip will look framed for social, captions and rails included.
  • Grab stills — tap the save button to export the current frame (with the overlay, if one is active) to your Photos library.

When to use it

  • Reviewing an exported render on your phone before you post it.
  • Checking that a vertical clip's action stays clear of platform UI.
  • Looking at colour and framing on a real device, away from your desk.
  • Trying the app's preview tools before you start a live stream.

When you're ready to mirror your edit live from your computer instead, head to Connect your iPhone.
