Show or hide non-horse videos

How the on-device detector decides what to hide, and how to override it when it gets one wrong.

The iOS app keeps your video list focused on horse footage by hiding videos the on-device detector decided aren't equestrian. You can override the detector either way — and your overrides stick.

What gets shown by default

The main video list shows two groups:

  • Horse videos — the on-device classifier saw a horse in at least one of three sampled frames (25%, 50%, 75% of the video) above a confidence threshold.
  • Unscanned videos — the detector hasn't run yet. They stay visible so you don't lose sight of fresh footage while ML catches up.

Videos the detector classified as not a horse are hidden from the main list — but they're never deleted, and you can flip them back at any time.

Override the detector

If the detector got it wrong on a specific video, you can correct it from the list:

  • Hide a non-horse video — swipe left on the row and tap Not a Horse. It disappears from the main list.
  • Restore a hidden video — open the hidden list (see below), then swipe left and tap Mark as Horse, or open the video and tap the same button in the detail view.

Manual labels always win over the detector, and they survive a re-scan — once you've told the app what a video is, it stops second-guessing you.

View your hidden videos

At the top of the video list, next to the filter icon, there's an eye toggle:

  • Eye icon — you're looking at horses + unscanned (the default).
  • Eye-slash icon — you're looking at the videos the detector hid. Tap any to review or restore.

Unscanned videos don't appear in the hidden list — only videos the classifier or you explicitly marked as not-a-horse.

Why some real horse videos get hidden

Wide arena shots, dark indoor lighting, or videos where the horse is partly occluded can fall below the detector's confidence threshold. False negatives are rarer than false positives, but they happen — that's why the manual override exists. If you notice a pattern, just flip the eye toggle and rescue the missed ones.

Privacy

Horse detection runs entirely on your iPhone using Apple's built-in Vision classifier. No frames or labels leave the device for this step — only a per-video yes/no flag is stored locally, alongside any manual override you set.
