Video skills and equipment
by Lars Aronsson 16 Apr '25

I just tried to watch some presentation videos from Wikimania. Some had very weak sound, some had no sound in the first minutes, some only played the first minute and then stopped. I don't think the Wikimania videos are unique in having such problems. Video is new to Commons, and the expert contributors are more familiar with still images. How can we learn to make better videos? Are there some good instructions? Perhaps a free instruction video (Wikibooks, but a video instead of a book) on how to produce good videos is what we need. In fact, the English Wikibooks has a title on "Video Production", http://en.wikibooks.org/wiki/Video_Production but it doesn't have a clear focus (pun not intended). It starts out with discussing satellite TV and has long sections on file formats in different operating systems. There is a help page on Commons for converting video to the Ogg Theora format, but that is only the last step in a long chain. Given that video is new, how can we find and rate videos, nominate "good/featured videos", and give advice on how to improve quality? Is the Commons village pump enough for this? Commons has a separate graphics village pump. Do we also need a separate video village pump? Current digital video cameras use hard disks or memory cards, instead of tape cassettes. Many new models cost less than 300 euro (or dollars), some as little as 120 euro (memory card perhaps not included). Some have a special "Youtube mode", and I guess that kind of usage is what drives the price down. What models are good, and what should one watch out for? We can find free still photos on Flickr and copy them to Commons. Is there somewhere we can find free videos and copy them? Yes, at the Internet Archive. Somewhere else? -- Lars Aronsson (lars(a)aronsson.se) Aronsson Datateknik - http://aronsson.se

I think this subject should also be discussed on the Commons mailing list, as this plan is to demolish the navigational structure of Commons. 2015-08-27 15:03 GMT+02:00 Romaine Wiki <romaine.wiki(a)gmail.com>: > No we have not a clear policy on only linking sitelinks to categories if > the item itself is about a category.

As I wrote before, that thought is too simple. You only say that a zero belongs to a zero, and a two belongs to a two, then you only describe the type of page, but you ignore the subject of a page. That subject matters much more than the namespace number. Especially Wikinews is a wrong example, as most categories on Commons do not have a 1 to 1 relationship with Commons. However, articles on Wikipedia do have mostly a 1 on 1 relationship with categories on Commons.

WikiDACH 2015 - Wikipedia tut gut
by Sebastian Wallroth 02 Aug '15

02 Aug '15

Vom 30. Oktober bis 1. November 2015 findet nun endlich im prächtigen Schweriner Schloss [1] die erste WikiDACH [2] statt. Der Landtag von Mecklenburg-Vorpommern gestattet die kostenfreie Nutzung damit sich die Welt der Wikipedianer (und aller anderen Wikimedia-Projekte) mit den Menschen der Region, sowie ganz Österreichs, der Schweiz und Deutschlands austauschen können. Teilnehmer können hier ihr Interesse bekunden [3] und es werden noch Helfer [4] gesucht. Wer einen Vortrag oder Workshop [5] anbieten möchte, trägt sich bitte ein. Bitte beschreibt, was Ihr anbieten möchtet. Ein griffiger Titel ist dabei sehr wichtig, außerdem natürlich das Format und die gewünschte Länge des Slots. Da wir viele Besucher erwarten, die die Wikipedia und ihre Schwesterprojekte noch nicht kennen, wäre auch eine Angabe hilfreich, ob sich der Slot für Anfänger eignet.
