Precision video study for Mac
Slow down the moment that matters. Fine-step through an instructional video, zoom from 10% to 300%, and pan across the picture to inspect details an ordinary web player can leave behind.

Built for active learning
Instructional video often hides its most valuable information in a fraction of a second. YTStreamPlayer turns those fleeting moments into something you can inspect, compare, and practice.
Movement
Pause at a dance transition, move forward one estimated frame interval at a time, and study exactly when weight, direction, or hand position changes.
Hands-on skills
Enlarge a knot tutorial to see which strand crosses first, then Option-drag across the magnified picture without changing the selected zoom level.
Precision work
Zoom into a tiny component, pan to the tool, and use the app timeline with estimated fine controls to compare placement before touching the real mechanism.
Craft and cooking
Study one fold, stitch, brush stroke, or cooking motion at a time. Keyboard controls help keep both hands near the work surface.
App Store gallery
Scroll through the same six Mac screenshots prepared for the App Store product page.
Purpose-built controls
Pause and move backward or forward by one estimated frame interval with buttons or arrow keys. Hold either button to repeat.
Fit the full picture, return to original size, or magnify the exact part of a lesson you need to inspect.
Option-drag, two-finger scroll, Option-arrow keys, or accessible menu commands move through an enlarged video without changing zoom.
Seek to a new point and continue from there after buffering. The player may land near a keyframe.
Use Space to play or pause, arrows to fine-seek, Command-O for a URL, searchable history, and contextual help.
Optional Google sign-in enables read-only YouTube search. Results create an ordered playlist with previous and next controls.
Privacy by design
YTStreamPlayer does not download the video, include an advertising SDK, or automatically transmit diagnostics. Loading and search connect to Google and YouTube only after the first-use disclosure is accepted.
Local controlsHistory, search terms, diagnostics, and MetricKit retention have independent settings and deletion controls.
Optional accountGoogle sign-in is used only for read-only YouTube search. Direct supported URLs can be opened without signing in.
Preview before sharingProblem reports and feature suggestions are created locally. You choose the information and destination.
Support that listens
The in-app report lets you review every included information group before anything is copied, saved, or shared.

Zoom, pan, and study video
YouTube’s embedded player does not expose decoded frames or source frame rate. Fine-step positions and frame readouts are estimates, and YouTube may seek to a nearby keyframe.
Playback requires internet access. Video availability, embedding, quality, captions, advertising, playback speeds, branding, and related links remain controlled by YouTube and the video owner.
