This missed the cut in the edit of a book chapter for an anthology the project team is working on. Thought it ought to appear somewhere as vaguely useful to what this project has done. The Circus Oz Living Archive research team have had innumerable, and significant, discussions about content and curation — the very stuff of the archive —… Read more →
Thanks to all who took part in the Digital Acrobatics symposium. Â Video and audio presentations will be available soon, but right now you canÂ see pics here.
Joining of Sequences 5.1 If the source media has been split into multiple files by hardware or software the most effective way to deal with such files is to: compress them using this protocol individually (things work faster when dealing with smaller files) use QuickTime 10.x to do a simple ‘butt edit’ by open the first clip locate the next clip in the finder drag the second clip into the first (which is open in QuickTime Player) it will drop in where you place it repeat click ‘done’ when finished and you will be prompted to save it name it, and when saved it will be ready for upload THE SETTINGS Description: 640 px frame controls on 1000kbs max resizing File Extension: mov Email notification to: Time remapping: source frames play at 24.000 fps Audio Encoder AAC, Mono, 24.000 kHz Video Encoder Width and Height: Up to 640 x 360 Pixel aspect ratio: Default Crop: None Padding: None Frame rate: 24 Frame Controls On: Retiming: (Fast) Nearest Frame Resize Filter: Linear Filter Deinterlace Filter: Better (Motion Adaptive) Adaptive Details: Off Antialias: 0 Detail Level: 0 Field Output: Progressive Codec Type: H.264 Multi-pass: On, frame reorder: On Pixel depth: 24 Spatial quality: 75 Min.

It emphasises the use of ready to hand video technologies (for example a mobile phone) and simple online tools for the collection and curation of video into more complex works. The sorts of projects that the students make are observational and poetic, and provide a way to rethink a) some uses of content for the archive, b) a methodology for creating poetic works using similar tools but with more ‘informal’ material from Oz gathered using ready to hand technologies.
Here is the video from our May 2011 Spiegeltent event, by filmmaker Anna Vaz.
Starting to collect links about HTML 5, and all the rest over on my usual research blog in the ” Resources ” section. Need somewhere to park this stuff.
Just a test for now as we work out tech requirements. However, a lot of really interesting research in this project happens around the table in our weekly meetings. This is where the thick practice of interdisicplinary research is made visible, but aside from meeting notes not really captured. So wouldn’t it be good to video this, just in case?… Read more →
Live streaming I think might let you jump to any point in a video stream without having to buffer all the data that is before that point, and it might resend some lost packets so you get more control over the integrity of the video (ie most of the data will arrive). But I have not been able to find anything specific about that yet. http live streaming introduction page http live streaming tech overview http live streaming tools (actually, you need an AppleID to find these) best practice for iPhone/iPad Apple intro to HTML 5 and video tech note about export settings for Apple hardware devices, lots of detail about data rates, codecs, max bitrates, framerates and the like, for the video nerd.
However, in the early days, when bandwidth was narrow, video was small, and not many of us actually played with it online, QuickTime had this thing called a reference movie (which was not the same as the reference movie option you get when saving a QuickTime file in QuickTime) which was a tiny little place holder video you created. … This is going back to the future because a series of steps and constraints have been reintroduced: if you want to send video or audio that is over 10 minutes in length over a mobile network (NOT WIFI) to an iOS device then you just have to use HTTP live streaming (this is the overview page ) If that isn’t enough then you must include a low bit rate version with a max data rate of 64 Kbps that it can default to when you hit that service shadow you need to run your compressed video through some other tools to get it ready for Live Streaming – this includes the Media Stream Segmenter, the Media File Segmenter, and the Media Stream Validator But it is ambiguous in the documentation if you have to do this, or it is recommended – essentially the protocol lets the client jump from different versions as it plays.
