Tag <a-scene arjs="patternRatio: 0.75">
<a-marker type="pattern" preset="hiro" vidhandler="target: #vid1">
--------
<a-marker
        type="pattern"

        vidhandler="target: #vid2"

Glitch : Multi Pattern Code

Solution

I think that actually it is not possible, because is not implemented. You could add as you did patternRatio to the <a-scene> but this will add the same patternRatio to all markers in the scene. You could add PatternRatio to the a-marker component inside the component-anchor.js in this way:

// FIXME
AFRAME.registerPrimitive('a-marker', AFRAME.utils.extendDeep({}, AFRAME.primitives.getMeshMixin(), {
    defaultComponents: {
        'arjs-anchor': {},
        'arjs-hit-testing': {},
    },
    mappings: {
        'type': 'arjs-anchor.type',
        'size': 'arjs-anchor.size',
        'url': 'arjs-anchor.patternUrl',
        'patternRatio': 'arjs-anchor.patternRatio', // add this line !
        'value': 'arjs-anchor.barcodeValue',
        'preset': 'arjs-anchor.preset',
        'min-confidence': 'arjs-anchor.minConfidence',
        'marker-helpers': 'arjs-anchor.markerhelpers',
        'smooth': 'arjs-anchor.smooth',
        'smooth-count': 'arjs-anchor.smoothCount',
        'smooth-tolerance': 'arjs-anchor.smoothTolerance',
        'smooth-threshold': 'arjs-anchor.smoothThreshold',

        'hit-testing-render-debug': 'arjs-hit-testing.renderDebug',
        'hit-testing-enabled': 'arjs-hit-testing.enabled',
    }
}))

you should rebuild the lib before using, run: npm install and then npm run build in the main AR.js folder. I have not tested the code so i can not sure that this code works. BTW it will be nice to add such a feature...
