Video Codex::Panasonic Lumix DMC-GF6 Quick Review

INTRODUCTION

Here is a quick review of the Panasonic Lumix DMC-GF6 Digital Camera (Micro 4/3 Sensor). First up is the unboxing video below which is also filmed with another Panasonic Lumix DMC-GF6 in auto-focus.


DISCUSSION

The range and versatility of this camera is truly astounding with the standard kit lens. Even for a novice such as myself I was able to get some brilliant creative shots in low light using the manual settings. This camera really does come to life when using the manual settings and although they are not as easy to tweak and control as Canon DSLR’s, they certainly do give a wide palette of variation.

FINDINGS

The maximum video recording time for the AVCHD and MP4 mode is 29 minutes and 59 seconds as expected due to EU regulations imposed on all digital cameras. See here for more information on why the 30 minute recording time limit is placed on digital cameras. If you require more recording time onboard, look at the Blackmagic range of cinema cameras. As expected they would have paid the additional EU taxes on being able to record for longer times. The time limit is imposed via red tape and is a legal president which stops manufacturers of cameras which limit the recording time, otherwise this is declared as being a video camera. There is also a time out for standby and a menu will display on the HDMI output when left unattended for a period of time. This is applied to many cameras and consumer camcorders to stop live streamers from using anything other than professional grade video cameras for this purpose. For users of Canon DSLR’s there is discussion of extending the recording time via Magic Lantern here. The recording of RAW Video is not possible, this is only available on Canon DSLR with Magic Lantern and Black Magic design Cameras.

Coders Codex::Decoding Video Streams to Textures in Unity 3d

INTRODUCTION

Here we will decode an Ogg Theora file streaming from the internet onto a plane surface scripted in Unity 3d.

DISCUSSION

The fastest method to do this as of writing is to look here and then attach this to the camera in a new unity 3d scene.

FINDINGS

The Unity docs do not seem to show a C# source example, so in full Blue Peter (UK) style: Here is one I made earlier.

Divide To Infinity Incorporates ‘Mind Biorhythm Dataspace’ with Daksyba Arts Collective

ABOUT
Daksyba are a collective of audio and visual artists from a range
of creative disciplines, combining voice, percussion, strings, didgeridoo, digital sound and video.

Daksyba Performance @ OV London Festival 2013

“Art is mostly experienced as the aftermath of the creative process. It may be composed, rehearsed, performed or recorded and as such it is but a reflection of that process. Improvisation, as a premise, invites the artist and spectator to share a moment and witness art as a unique event as it emerges, truly in the here and now” – Illi Adato, Artistic Director, Art of the Moment.

Art of The Moment is a 2 day event integrating music, dance and visual arts in fresh new ways and re-examining the relationship between the different medium. It is a celebration of art created in the glorious uncertainty of the here and now, deep in the heart of spontaneous composition.

The festival will feature contributions from the likes of the amazing Oren Marshall (collaborations include Radiohead and Charlie Haden), Maggie Nicols, Anton Mobin, Phil Minton, The Irrepressibles, Matt Black (Ninja Tune, Coldcut), h2dance, Mixmaster Morris and many other leading artists in the field.

It takes place in one of London’s most fascinating art hubs, The Albert in Queen’s Park, and is open to everyone to come and enjoy, explore, experience and get involved.

HTML5 Video

Until now, there has not been a standard for showing a video/movie on a web page.

Today, most videos are shown through a plug-in (like flash). However, different browsers may have different plug-ins.

HTML5 defines a new element which specifies a standard way to embed a video/movie on a web page: the element.
