What are all these downloads?

We offer as much media from a talk as possible. This might include the speaker's original presentation materials as well as recordings of the talk. The presentation materials are in the "Presentation" column of the table. These are often OpenOffice.org files, but may also be PowerPoint, HTML, JPEG or PNG files. We offer PDF versions of most presentations too. You obviously need to use the appropriate program to read these presentation files, for example xpdf or Adobe Acrobat Reader for PDF files. The files in the "Presentation" columns do not contain video or audio of the talk.

I've got the notes, now I want to see the talk!

The videos of the talks are in the "Video" column of the table. If there is no link, then we don't have video of that particular talk. If there is a link, clicking it will download the file, unless you have a media player plugin enabled in your browser. Save the file to a known location and then play it back with your favourite media player. If you have a media plugin installed in your browser, then the video will start playing automatically. The download files are quite large - between 30MB and 100MB, depending on the length of the talk and the encoding. You should ensure you have sufficient hard disk space to save these files before downloading, and may want to use a download resume program if you are using a dial-up connection.

The videos are released under Creative Commons license, specified at the beginning of each video and on the download page. For clarity's sake, you may play, pause and rewind the videos to your heart's content.

The video files are too big for me to download / Can I get a better quality version?

Download size is a major concern for us when producing the videos. The files we produce have to be a suitable size for people to download. Although we host the files on archive.org, people who download the videos still have to use their bandwidth to do so. We try and produce files that are quick to download on a broadband connection. This rules out using high quality formats like raw MPEG2 video and WAV audio. We use compressed formats to make the downloads as quick as possible. You can expect file sizes to be 30MB for a short talk and 90MB for an hour-long talk. These should take between 10 minutes and half an hour to download. If you really want a higher quality version, then we may produce a DVD of the talks in the future.

If you are on dial-up and cannot download these files easily because of their size, then please ask on the MailingList and someone may be able to post you a CD-ROM with the files on. Alternatively, attend a LUG meeting where there is bandwidth available to download these files.

Why is there more than one version of the video available, and what's the difference?

If you are running Linux, you should probably download the OGG version. The OGG version should play back using Totem, Xine, Helix Player or Mplayer (at least) on the mainstream Linux distros. If you are running Windows, try the WMV version. The WMV version should play back on a Windows system using Media Player. If you can, use the OGG version, as it's better quality in a smaller file size. If you are having problems playing these files, please see the /OggFAQ and the /WmvFAQ. Recently released videos also have an MP4 version available. This video file is suitable for use on certain portable media players, as well as computers.

There isn't an OGG or WMV version of the talk I'm trying to download, just an AVI.

Please see the /XVidMP3FAQ.

Why are the video filenames all different?

Basically, different people helping out! Sorry, but we're dependent on volunteers and sometimes things get forgotten.
