Videos about lab.js HOT 1 OPEN

I have never used videos with lab.js, and do not know the "proper" way to do so. But as an exercise I added an html.Screen component and then added a video element there, e.g.,

<video controls><source src=${this.files["movie.mp4"]} type="video/mp4"></video>

I also uploaded the video file (a small one) to the component. This all worked. I would not, however, trust this if you need to present a video with millisecond accuracy.

I had to use a small file to avoid the "This file is too large to be opened" error in the Builder. That seems to be a limitation of what the Builder allows you to upload, not a limitation of lab.js itself. To get around the limit in the Builder I edited my video element to

<video controls><source src="movie.mp4" type="video/mp4"></video>

I then exported the study for local use, manually added my larger movie file to the same folder as the study, and this worked.
