Bizarre: France government agency cautions children against watching 3D

November 6, 2014 3DM Leave a comment

Evidence free medicine: BBC News – French health watchdog warns on 3D usage for children.

Scholar.google.com did not turn up any papers on the subject. Pubmed.gov did turn up some papers:
http://www.ncbi.nlm.nih.gov/pubmed/23224123 – this paper formed an hypothesis, not a conclusion – and is referenced by the government agencies as the basis for this recommendation. The abstract says “As there is hardly any information available in the medical literature on this subject it is the aim of this article to provide an overview of the technology and physiology with the advantages and disadvantages.”
http://www.ncbi.nlm.nih.gov/pubmed/23928879 – looked at a group of people with pre-existing vision problems to understand the impact of bad 3D imagery on them. Pretty much the same in this paper – http://www.ncbi.nlm.nih.gov/pubmed/24516978

Thus, these recommendations are based on the practice of evidence-free medicine.

Youtube 60 fps demo video clip

October 30, 2014 3DM 2 Comments

I have posted a demo video clip of Youtube’s new 60 fps support.
To play at 60 fps, you must select 720p or 1080p viewing modes and use the Chrome browser and the HTML5 video player. The Flash player (used in many other browsers, by default) does not appear to support 60 fps and just stops working.

However, if you wish to watch 3D clips on Youtube, then you probably still want to use the Flash-based video player – but it appears we probably will not be watching 60 fps in 3D. It’s possible as we can always upload side-by-side 3D videos in 60 fps mode, but the HTML5 player will display them in their original side-by-side format – you may have to manually switch your TV or monitor to side-by-side 3D mode in that case, in order to watch in 3D.

For niche video content producers, Youtube is a dying platform

July 8, 2014 3DM Leave a comment

Youtube is a dying platform for niche video content producers.

Youtube: Video 1 received 196 views in 3 weeks.
Flickr: Video 1 received 2,648 views in about 2 weeks.

Youtube: Video 2 received 116 views.
Flickr: Video 2 received 787 views

Youtube: Video 3 posted Jul 6, 22 views.
Flickr: Video 3 posted last night, 29 views already.

Hmmm… Youtube has done to its content search algorithm what Facebook has done to their newsfeed – and both are going to lose their content producers!

The same type of videos I posted a year and longer ago to Youtube would receive hundreds to many thousands of views. But in 2014, similar videos are lucky to get even 100 views.

We know Youtube has changed their search algorithms, their recommended and “Watch” lists and how they prioritize who gets listed. From the perspective of niche video content producers, it is clear we are better off posting our content elsewhere. Or switch to producing video game mashups and cat videos!

Just guessing but Youtube seems to have become a platform for a group of established Youtube stars, up and coming music acts and “cover” singers, and viral videos.

The other possibility is fundamental changes in viewership – the audience now wants very high quality content (think Devin Graham or Corridor Digital), the audience now wants “channels” that focus on specific topics (there are some hints that this is happening), the audience wants “personalities” (strong hints that this has happened). The type of content people were looking for a year or three ago has changed – mountain bike racing, big events, air shows, etc – has all faded.

But that explanation fails to explain why the same video is watched 8 to 15 times more often on Flickr than on Youtube.
