22C3: Private Investigations (2005) on CCC Event Blog

22C3 audio and video podcasts available

Tue, 27 Jun 2006 23:53:28 +0000

Oh yes, it took a while. But we finally managed to finalize the 22C3 audio and video recordings and to provide them via a podcast feed as well.

We now provide audio recordings in MP3, MPEG-4 Audio and Ogg Vorbis format and videos in MPEG-4 AVC (H.264) 320×240 format in addition to our originally posted full resolution MPEG-4 versions. The new videos run on the iPod and are around 25% the size of the big files.

To make the material easily accessible, you can subscribe to the main podcasts feeds for either audio or video or just download the files directly from these web pages:

We’d love to hear from you what you think about the content being offered using podcast technology. ~~As a convenience, we also provide podcast feeds for the Ogg Vorbis and the MPEG-4 AAC audio versions.~~ These are considered to be experimental. Drop a comment if you think if the podcast in general or these alternative versions are useful for you.

All podcasts are hosted by the Chaosradio website which is also our central point for CCC’s audio and video podcast content including recordings from other CCC events as well.

About the event ID

Fri, 21 Apr 2006 12:29:00 +0000

As you might have noticed, each lecture recording has an ID (three or four digits long) that is embedded in the file name and the introductory slide in the video itself. You also find this event ID on the 22C3 Fahrplan being used in URLs and such.

The more important information is that this ID will be unique over ALL Chaos Communication Congresses since 1998 (not everything is online properly but it will). So there is not only no clash with IDs used at 21C3, there won’t be one with 23C3 as well. And this goes for all events that have been planned with our Pentabarf conference planning software, including the recent Easterhegg event in Vienna and the upcoming regional events like Datenspuren, GPN5, MRMCD, ICMP3 and others.

This should make our conference program even more trackable.

Gentlemen, fire up your clients (2nd Update)

Fri, 21 Apr 2006 01:30:40 +0000

All recorded 22C3 videos are online now (via BitTorrent and HTTP). Get the individual torrent files or get all torrent files in one tar.gz archive: 22C3-videos-complete-20050506.tar.gz (here are the checksums).

We still plan to provide complete torrent sets and extra torrent sets optimized for DVD-sized download chunks so that it is easier to archive that stuff. We are a bit distracted by other stuff currently, but we will bring you an update soon. Audio-only versions will follow soon as will the iPod-versions.

If you want to mirror the content, please use BitTorrent to get the files and publish your server address in the Wiki. All mirrors are welcome. Please make sure you keep track of the final updates by subscribing to this blog.

Update: We have now updated our archive to include all 140 recorded events. Please use the new links above to get the additional stuff. Recordings for these events have been added: Personal experiences bringing technology and new media to disaster areas, Bluetooth Hacking – The State of The Art , Elektronische Gesundheitskarte und Gesundheitstelematik – 1984 reloaded?, Die Technik im neuen ePass, Biometrics in Science Fiction and Black Ops Of TCP/IP 2005.5.

It’s Feedback Time

Thu, 20 Apr 2006 21:59:07 +0000

We are coming along well. The recordings are on the server now and we are creating .torrent files now. Once ready, we will publish them so that you can use BitTorrent to download them. Once we feel that the first run is over, we will open direct HTTP access to the files. If we would do this from the beginning, I am sure the server wouldn’t survive it.

So now that we are able to give you what you want, there is something we want from you:

PLEASE PROVIDE FEEDBACK ON THE LECTURES!
USE THE FEEDBACK FORMS!

Each event has it’s own unique feedback URL, easily accessible on each event’s web page in our 22C3 Fahrplan. So it shouldn’t be too hard to locate the proper resource.

For instance, if you just seen the recently posted video of our 22C3 Opening Event, why not go ahead and give us feedback on this on the corresponding feedback page? Oh, that easy? Yes. That easy.

Apart from the rating, please also leave an opinion on the lecture as well. This doesn’t have to be much, just speak your mind and let us know what you think.

This whole feedback business is very helpful for us in determining what was okay and what went wrong. So please take your time and tell us what you think. Thank you.

Here we go

Tue, 18 Apr 2006 22:25:33 +0000

I uploaded the first official 22C3 video recording: it’s the recording of the opening speech and keynote. Unfortunately, the video quality itself is not good as this is one of the recordings that had to be recovered from the failed realtime recordings. Most other videos will be much better. Here it is:

22C3-390-en-private_investigations.mp4 (MPEG-4, 1.2 MBit/s)

A few notes on the format: this is a standard MPEG-4 encoded (audio and video) file in a standard MP4 container file. The native resolution is 720×576 pixels but as this is derived from video, it is a non-square pixel format. The file has the proper bit set (the so-called PAR or SAR bit) to reflect this property. Your video player should honor this bit and scale the video on playback, effectively extending the displayed area to 785×576 pixels.

We would be happy if you could download the file and post success or failure of playback as a comment to this post so that we know we are safe (or not). We will post the rest of the videos once we are sure everything is fine.

Sorry again for all the delay. We will spend another post on what we had to go through to make these works available.

Ninety-Five Percent

Sat, 08 Apr 2006 19:10:15 +0000

Yes we know, we suck. But rest assured a lot of work is being done to bring the 22C3 videos out. Consider it to be 95% done and we are pretty confident you will hear from us soon.

There has been a lot of talk on why things took so long (again) and although I won’t dig into the whole story here, it was a sequence of disasters that started with almost all realtime recordings being plagued by non-linear syncing of audio and video. So most of the material had to be recovered and re-encoded from DV backup tapes which took a long time (around 2 TB of data had to be moved to and fro).

As a few backups failed as well, we had to manually recover the de-synced realtime recordings and all the talks in the main lecture hall had to be manually re-mixed as well as we have been recording with two cameras at the same time. Confusion took its toll as well and now we are spending significant time to put some quality assurance in reviewing the encoded material and to make sure that the files are consistently and correctly named. We want to be sure that once we put the stuff online we don’t have to recall it again.

A final bunch of lectures will even take a bit longer but we are about to release 95% of the lectures sometime next week. We hope we will be lucky enough to achieve this goal but don’t blame us if we miss the mark once more as this is not the only thing we have to take care of these days with limited resources.

Thanks for your patience so far. We are sure you will be pleased with the results.

22C3 Fahrplan 2.0 Update

Wed, 05 Apr 2006 17:53:01 +0000

We just released the “2.0” update to the 22C3 Fahrplan which now includes most lecture materials (excluding just a few slides by some lazy speakers). There will be some minor updates in the coming days to add the remaining stuff and another update to point to the recordings once the audio and video files are online.

22C3 recordings update

Wed, 15 Mar 2006 04:01:02 +0000

We expected to be done by now but there is still work to be done. Main problem is that we have to manually rearrange around 50 sessions to fix the audio syncing which was garbled due to technical problems. But we are making progress, step by step and we are slowly reaching the end of the tunnel.

As the stuff is ready, it will be available both via BitTorrent and a podcast (podcast might kick in a bit later to wait for the main rush to flow down).

Thanks for your patience.

Chaosradio International

Wed, 22 Feb 2006 01:47:40 +0000

We are promoting our English language Chaosradio podcasts now under a new label called Chaosradio International to make clear what is easily consumable by non-German speakers. We released episode CRI005 today and you can access the other four episodes as well that feature interviews with selected speakers of 22C3.

22C3 Recordings: The Final Samples

Tue, 07 Feb 2006 16:27:26 +0000

Okay. Good news on the horizon. All videos are collected, a naming scheme is defined and we have sorted out our formats. The encoding machines are ready to run. And will be started any moment.

To give you the chance for some final checking, we have put up some samples for the various formats for you to test. So if you are technically inclined you might want to check them out in terms of quality and compatibility. The sample is always the same two minute clip.

MPEG-4 H.264 320×240 iPod Video compatible (MPEG-4 H.264 Baseline Profile Video, MPEG-4 AAC Audio, MP4 Container, 0,23 MBit/s)
MPEG-4 720×576 (MPEG-4 Video, MPEG-4 AAC Audio, MP4 Container, 1.2 MBit/s)
Windows Media 9 Standard 720×576 (WMV9 Audio/Video, WMV Container, 1.9 MBit/s)
MPEG-2 720×576 (MPEG-2 Muxed Audio/Video, VOB Container, 6 MBit/s)

Take your pick and feel free to comment here.

When will the recordings be available?

Sun, 05 Feb 2006 02:06:15 +0000

“…it’ll probably be only days away.”

More info from the people working on them here.

22C3 Speaker Interviews

Wed, 01 Feb 2006 01:16:29 +0000

After pointing you to a German summary in our podcast let’s also point you to four podcast interviews done with 22C3 speakers. Each podcast begins with a short German introduction but the interviews are held in English.

CRE010: Régine Débatty (lecture, speaker info)
CRE011: Joi Ito (lecture, speaker info)
CRE012: Eric Blossom (lecture, speaker info)
CRE013: Jacob Appelbaum (lecture one and two, speaker info)

We should have done more of this stuff! And we certainly will in the future.

22C3 recordings and slides

Mon, 09 Jan 2006 02:42:29 +0000

There has been some confusion regarding the AV recordings and slides of the 22C3 lectures. So let us explain what is coming and that everything will be fine.

The good news is: everything has been recorded! Yes, we have had our accidents but the fallback systems have worked so nothing is lost. As quite a few recordings have to be recovered from tape, the whole process will take a while but we are confident that we can deliver what everybody wants by the end of January.

More confusion has been generated as a couple of recordings have been available in WMV format up front which made many people believe it is our intention to provide everything in WMV only. This is not the case. The truth is that this has been just an additional service that was not related to the main documentation process.

So everything will be cool. Every single lecture will be available in the following video formats:

MPEG-2 (5 MBit/s)
MPEG-4 (1.2 MBit/s Simple Profile)
WMV (250 KBit/s)

In addition, all lectures will come in audio-only versions also in MP3 and OGG format in reasonable bit rates. All video and audio recordings will be licensed under the Creative Commons Attribution-NonCommercial-NoDerivs 2.0 Germany license.

And yes: we’ll make sure the MPEG-4 version will run on the iPod. There might be a iPod-compatible MPEG-4 H.264 768 KBit/s version as well in the near future. We’ll see what we can do.

Another idea is to provide the lectures in original order in a podcast that releases a lecture a day (or so). If you think this is a good idea voice your support by dropping a comment here.

The slides will be available on the event description pages in our Fahrplan as soon as they are available. Most of the stuff is already there and as long as all speakers will send us their slides, we will publish it. If you are a speaker and you haven’t sent us the slides, please do so.

This is going to be the best documented C3 ever. We are very happy about this.

Did you know?

Fri, 06 Jan 2006 20:37:28 +0000

Some people still get it wrong but I’d like to clarify it here one more time: it’s neither the “Chaos Computer Conference” nor the “Chaos Computer Congress”. It’s the “Chaos Communication Congress“. Not that it is too important but in the end we would be happy if you would just get it right ;)

In case you’re still confused, just stick to the “xxC3” moniker we have established in the recent years. It’s our primary choice for tagging as well.

Thanks for listening. This was a recording.
