On the beginning of this year we decided to transcode our old videos to have mp4&#x2F;webm&#x2F;hls renditions (we only had .flv at that time) so we could also generate the thumbs. For new videos I created this project <a href="https:&#x2F;&#x2F;github.com&#x2F;flavioribeiro&#x2F;video-thumbnail-generator" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;flavioribeiro&#x2F;video-thumbnail-generator</a>  and we are integrating it with our encoding pipeline.
