The goal here was to create a quick video player for zooming in on sections of video, going frame by frame, and (optionally) showing the original pixels.
- It only works in Chrome, Edge, or Opera (Due to reliance on WebCodecs)
- Should work with most mp4 files
- To load a file, drag it into the window
- There are also some famous presets included under the "Video File" menu.
- By default, it shows the actual pixels when scaled up. Select "Smooth" to use more traditional smooth scaling.
- There's currently no audio
- Controls:
- Spacebar = pause/play
- A slider at the bottom of the screen to move the playhead
- < and > stepsingle frames
- left and right arrows play forward or backwards while held
- up and down arrows play at 10x speed
- Mouse Wheel = zoom in/out (on the position under the mouse)
- Left Drag = Pan image
- Right Drag left/right = scrub video
- Center Drag left/right = Zoom
- Double click = reset zoom/pan
- U = show/hide UI
- F = full screen
Bugs:
- Not working with 60Hz video (plays at half speed)
- Not working on mobile devices.
I'll update this OP as I add features and UI improvements (suggestions and requests?) Eventually, it will form the basis for some video analysis tools.
