To view videos stored in your GR IV’s built-in 53 GB memory:
- Press the ▶ Playback button.
- Press and hold the Movie button to switch between the SD card and internal memory.
- Alternatively, go to MENU → Playback Settings → Playback Memory Selection → Internal Memory.
- Press the – side of the zoom control to display thumbnail images.
- Look for thumbnails showing a movie duration, select one, and press OK to play it.
Important: The GR IV does not appear to offer a video-only playback filter. You can select internal memory, but photographs and videos remain mixed together.
Workaround: Connect the camera to your computer, open its internal storage, and filter files by video type (such as .MP4) to see only your recorded videos.
