Hmm... it require Java, cool. Waiting for IcedTea to do some release, so I can also enjoy blip.tv in web browser :) next step, take the videos that prof andrew handed me of freed.in sep 2007 and pull out some segments. those interested to pitch in, we could meet next week and collaborate on doing this. Instead of pulling out some segments, how about making available complete videos of Freed.in available online on WWW, or at least available inside JNU network, hmm...? So, how about running ffmpeg2theora on those DVs. I've transcoded couple of AVI MPEG2/MP3 videos (of 1hr-3hr. duration) to Ogg Theora/Vorbis on my desktop, sometimes nightly jobs. The output is satisfactory, and in most of the cases 50%-66% reduction in size, and sometimes 5%-10% reduction in size. e.g. ftp://ftp.vim.org/pub/vim/stuff/7Habits20.avi (506 MiB/DivX MPEG-4/MP3) got reduced to (200 MiB/Theora/Vorbis). The time ffmpeg took to re-encode videos is playback time (+/- 20%) on my Intel Pentium 4 630 (EM64T/3GHz), 2 GB RAM (400MHz/Dual Channel) with sometimes X running with KDE/GNOME or sometimes nightly. I've no experience of DVs, but if DVs are available in RAW format (which I think is uncompressed), then its less time consuming to encode them, hmm...? So transcoding of those DVs can be scheduled nightly on some boxes at JNU. Anyways, anyone aware of distributed audio/video transcoding application, so that one can optimize performance of transocing in a GRID environment, hmm...?

Cool. i just tried this. here is the link to the footage: http://blip.tv/file/589104/ and i chose from the drop-down play web-version of ogg theora. horridly enough, it asked me to download the JRE. again. i have already downloaded and installed it. could someone else please try if this is consistent? 11. optionally, also adds to archive.org if i have an account there.

Instead of pulling out some segments, how about making available complete videos of Freed.in available online on WWW, or at least available inside JNU network, hmm...? there's a reason raw footage needs to be edited down. it's to cut out the boredom of watching 8 hours that has probably 4 hours of stuff worth watching. besides, who's going to watch one huge cunk of say a 90 min or 2 hour video? so whichever way the cookie crumbles, you need to make short segments, perhaps of 15 minutes each, so people can skip through to what they wish to watch. So, how about running ffmpeg2theora on those DVs. I've transcoded couple of AVI MPEG2/MP3 videos (of 1hr-3hr. duration) to Ogg Theora/Vorbis on my desktop, sometimes nightly jobs. great to hear this.

dear all, 01. transferred this footage from my miniDV camcoder over a firewire card straight into kino running on ubuntu feisty. a few years ago configuring firewire was a real pain under gnulinux. now it's transparant. have card, will travel. kino is a gpl video-edit software. http://kinodv.org 02. video trimmed directly in kino, which is sensible enough to understand segments from the tape automatically. 03. created the simple title and credits using kino's built-in titler effects filter. for subsequent video-submissions, have figured out how to author more sophisticated titling sequences. 03a. transition effects such as fade in and out rendered through kino. 04. downloaded and installed ffmpeg2theora. 05. joined three segments into one in kino. one-click stuff. 06. exported ogg theora file, from the 720 x 560, to 640x480, directly. the original raw dv is 540mb. the final ogg file a mere 23mb. 07. created an account on blip.tv after recoiling away from youtube's draconian terms--and-conditions. http://niyam.blip.tv 08. blip.tv automatically transcodes ogg theora to flv, and also allows me to offer the option of the original source ogg theora to visitors. cool! 08a. extracted a still image from kino to use as the thumbnail for the video gallery. 09. blip.tv allows choices of creative commons licenses to be applied to the video. 10. automatically links it to my flickr account, and once i start a blog, to it as well. also allows other rather interesting features, such as link to myspace, etc. 11. optionally, also adds to archive.org if i have an account there. 12. rss feeds to miro, even itunes, available. 13. direct upload from mobile phones to blip.tv possible. 14. option to allow your videos to be suitable for mobile viewers as well. all the way till HDTV. w o w ! in fact, blip.tv encourages you to publish at broadcast quality while using high-compression. 15. lots more to this stuff. am specifically excited and fascinated by the paradigms and workflows available under a 100% foss value-system and while using gnulinux. suddenly, video is just becoming the coolest thing to do under foss. discovered kino outputs flash format files directly too. thse are *.flv, and also *.swf with some xhtml wrappers. interestingly, blip.tv asked for a java runtime edition (JRE) to be installed under firefox for me to view the video. was hesitant to do this due to the problems i faced last month with my system. however, braved it and installed the JRE. fortunately, everything worked flawlessly. next step, take the videos that prof andrew handed me of freed.in sep 2007 and pull out some segments. those interested to pitch in, we could meet next week and collaborate on doing this. recommend we create a separate group id for this on blip.tv, either ilug-d, linux-delhi, or freed.in. let the discussions begin. regards niyam -- niyam bhushan ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - February 22/23, 2008 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
