Dr Ari Jaaksi's keynote speech from OSiM 2008
The first of many OSiM and Maemo Summit recordings have been put online. This one is of Dr Ari Jaaksi's keynote speech at OSiM World 2008 where he discusses the future of the Maemo Platform.
Slide are here:
All recordings were done in lovely high definition but google seems to down covert it pretty badly. I'm still looking for a better host so if there are any suggestions, leave a comment below.

Did you contact andrew regarding putting this up on maemobox?

Yes, Vimeo has 500 MB upload limit per week, but it is manageable in two ways:
- First of all, the video is encoded to have 3 Mbps and be 720hd (using the Quicktime export in the iMovie for example to encode to H264). That saves some space. The default audio is PCM, but changing it AAC saves some space further. For example Kate Alhola's 1 h 20 minutes presentation was 470 MB if I remember correctly. The Maemo Summit music video linked by some commenter, was under 100 MB.
We are doing with Kate so that either one uploads a video per week and we can have two long videos published per week this way with joint effort (totals 3 hours of video). I haven't had problems with the upload limit that much therefore unless the video is extremely long. But 1 h 20 minutes of HD material is almost a size of full length movie, I presume that a talk can be fitted into it, assuming that you use some good tools to encode the video - if you are not using Mac, then it might be a bit trickier, you might need to look at mencoder (which runs on Linux, Mac and Windows) which does presumably a lot nicer work than some proprietary MS stuff - I have converted some my HD videos with that, prior I got a Mac - it was back when I had only Linux machines around.
Vimeo is excellent service and I have not found that would offer either better resolution or better length for the video. You need to encode it very well with proper codec and proper bit rate and not put anything less compressed to the upload than what is what you get when you stream the HD stream. Otherwise you are spending just your upload limit for nothing.
The weekly limit seems to be also for calendar weeks, so if you upload something on weekend, you may be able to already upload on Monday.

Good points Karoliina.
I'm having to transcode under windows because of the AVCHD format but I'm taking them over to cinelerra under Ubuntu to add slides and do the post-processing. AVCHD can be done under Linux but I have never been happy with the result.
I'm still experimenting. For example I uploaded a higher quality version to blip.tv but that seemed to have changed the format from 16:9 to 4:3 - http://blip.tv/file/1289824 and I can't find an option to change it back. (I also forgot to fix the interlacing that you can see on it).
I may succumb and buy an imac for video and photo editing as, I'm sorry to say, the offerings under Linux in this area aren't so strong.
Low res is better anyway...
Low res is better anyway... there are some devices out there that have problems with high definition content ;)

Vimeo has a 500mb weekly
Vimeo has a 500mb weekly upload limit and some of my recordings are way above that. If I can keep the sizes below 1gb then blip.tv looks like a good candidate.
