Angular – Property binding ngif not used by any directive on an embedded template

I am creating a simple application in Angular (Angular2 RC4) and I'm finding it difficult to run the application with the live server in nodejs.

I would like to aid as to what I can do to work around the error that is appearing in the Chrome console.

Erro in console Chrome:

browser_adapter.ts:82
EXCEPTION: Template parse errors:
Property binding ngif not used by any directive on an embedded template. Make sure that the property name is spelled correctly and all directives are listed in the "directives" section. ("
</video-list>

[ERROR ->]<video-detail *ngif="selectedVideo" ="selectedVideo">
</video-detail>"): AppComponent@8:0**

app.component.ts

import {Input, Output, Component} from '@angular/core'
import {Config} from './config.service'
import {Video} from './video'
import {VideoListComponent} from './videolist.component'
import {VideoDetailComponent} from './videodetail.component'

@Component({
    selector: 'my-app',
    templateUrl: 'app/app.component.html',
    directives: [VideoListComponent, VideoDetailComponent]
})
export class AppComponent {
    title = Config.TITLE_PAGE;
    videos: Array<Video>;
    selectedVideo : Video;

constructor() {
    this.videos = [
        new Video(1, "Test", "www.test.com", "Test Description"),
        new Video(2, "Test 2", "www.test2.com")
    ]
}

onSelectVideo(video) {
    //console.log(JSON.stringify(video));
    this.selectedVideo = video;
}
}

app.component.html

<h1 class="jumbotron">
