Hi all,
Observations on the upload and playback of https://commons.wikimedia.org/wiki/File:Wikipedia_5_million_articles_milesto... :
1. I'm impressed by how much the video compressed, down to 1.97 Mbps on WebM 1080P.
2. I had multiple problems when uploading this file in WebM/VP9 format. Firefox crashed every time I tried to use the upload wizard with chunked uploads enabled. IE was successful after I changed my chunked upload setting to 1 simultaneous upload.
3. The upload progress bar was very inaccurate on Firefox. On IE, the bar seemed to indicate the upload progress of the 5MB chunks rather than the progress of the whole video.
4. The automated transcoding process to multiple formats on Commons is nice, although there was a notable decrease in audio quality on the OGV file that I downloaded.
5. On playback of the video in ENWP by clicking the thumbnail which results in the video popup window, I think it would be good to make the option to fullscreen the video more obvious to the viewer inside of the popup window.
Thanks!
