the video installations I made in 2006-2008 did the following on a single Mac Quad G5 (later MacPro)
- Display live feed from 1080i camera - record live cam to disk at full frame rate - put live feed into 300 frame buffer and scrub through it at various rates - play up to 4 1080i clips off of two hard drives. This was all done with plenty of CPU in reserve. The codec was AppleIntemediate which is simply Photo-JPEG with specific CPU optimizations. You can see one of these in the lobby of OneArts Plaza in Dallas, Qualcomm HQ in San Diego and several private collections. http://www.lincolnschatz.com/category/lincoln-schatz-recent-new-media-video-art-installation-from-here-commission-for-one-arts-plaza-dallas/ On Fri, Sep 24, 2010 at 5:18 PM, palmieri, ricardo < ricardopalmi...@gmail.com> wrote: > some tips to use hd videos under gridflow/gem? hd videos in photoJPEG > looks so heavy. > i would like to hear experiences using HD video under pd. > > cheers > > > palm > > 2010/9/24 Mathieu Bouchard <ma...@artengine.ca>: > > On Fri, 24 Sep 2010, Matteo Sisti Sette wrote: > > > >> When talking about video codecs, I think/thought there is actually no > >> difference, that is, motion-jpeg would be just a name for "photo-jpeg > used > >> to encode a video stream" as opposed to encoding an image.
