About Saving Visitors' Bandwidth on a Website with Videos
To avoid preloading all video data in <video> tags, use one of the following approaches with the preload attribute:
Show a placeholder image
<video preload="none" poster="{{ post.video_cover.url }}" controls>
<source src="{{ post.video.url }}" type="video/mp4" />
</video>
Show the first frame of the video
<video preload="metadata" controls>
<source src="{{ post.video.url }}" type="video/mp4" />
</video>
