We finally got round to watching the recent documentary by Yann Arthus-Bertrand. Very interesting and a real eye opener that everyone should try to watch! Nary a truer sentence has been spoken than in the Matrix when Agent Smith describes humans as a virus... "you move to an area and multiply until every natural resource is consumed" - how true.

At about one and a half hour in length, it's a bit long to be watching on YouTube (although they do have the HD option on there), otherwise it is best if you can get your hands on the Blu-ray or DVD version as there's a lot of information and visuals to take in. Brilliant footage.

After losing one Playstation to the dust devils, I had to start again saving up the necessary points and podium wins to acquire the coveted Ferrari F2007 Formula 1 car.

As can be seen on our GT5P Visitor Leaderboard, the familiar vehicle for the Eiger Nordwand track is the Mitsubishi Evo, but the Ferrari F2007 is in a different league. Fantastic!

In terms of extreme adventure sports, it doesn'y get more exhilarating than this currently. Screaming down a cliff face in a flying squirrel suit ... I mean, are you completely bonkers?

If had balls big enough, I'd be right there with them, but for now I'll just have to enjoy the video and dream of one day flying like superman.

With such an impressive Gran Turismo 5 Prologue (GT5P) setup here in the house of Grundlefly, we thought it would be fun to subject visitors to a timed lap competition akin to the 'Celebrity in a Reasonably Priced Car' competition on Top Gear.

To keep it reasonably fair, all visitors have to race the same car on the same track, although the number of attempts is limitless (since some just want to keep improving their time, else they won't go home!). The chosen car is the Mitsubishi Lancer "Evo" 2006 and the course is the Eiger Nordwand (Class C).

There has been some pretty intense efforts, with shouting, cursing, shaving of milliseconds, sweat attacks, spin-outs, missed gears and beer breaks. All in all, good healthy, family fun!

It has taken me many months to get to a stage where I am happy with the quality of uploaded HD videos onto YouTube (now that they support a maximum resolution of 1280x720). At times, I was pulling my hair out, but now I think I've got a reasonable solution.

One of the main problems I had to overcome was getting rid of the interlacing effect on the exported video. Final Cut Express (FCE) imports AVCHD video OK and does an automatic QuickTime conversion to (squashed) 1440x1080 interlaced video. Exporting with QuickTime conversion and checking the 'De-interlace source video' option didn't fix the problem. The only solution I have found is to drag the de-interlace effect onto each and every video clip and make sure the Field Dominance property is set to Upper(Odd).

Once ready to export, select 'Export > Using QuickTime Conversion' as a QuickTime Movie with [Video options: Compression: H.264, Quality: High, Encoding mode: multi-pass, Dimensions: 1280x720, Scale: crop] and Audio options [Format: AAC, Bit rate: 256 kbps]. All other settings remain as default.

There was a period on YouTube where HD audio would be out of sync with the video (the low quality version would play OK), but this has now been fixed and the player chooses to skip video frames in order to keep sync'ed (a better solution in my view).
