Video Resolution
Wed, 06/03/2009 - 18:25
I'm looking to install the Kaltura Community Edition Server to teach the basics of video editing across a LAN for a course this summer. Before I go ahead and grapple with the installation I'd like to know what is possible out of the box so to speak with the server with regards the resolution of the final edited video projects.
Specifically is it possible to specify the resolution and proportions of the video files. The LAN would support much higher resolutions than the Flex players I have seen so far. Is there an admin panel where I can change this - or would I have to create my own custom Flex controls?
Finally is there an equivalent of an EDL, which I could use to create HD content from edits which were specified using lower resolution interfaces?

Thanks for the reply - seems should be possible to do all sorts with the SDL. As I'm trying to mix a set up with web based editors producing a collaborative edit, and the final edit being made with Final Cut Pro - it should even be possible to convert the SDL to an XML File Cut can use.
First I've got to try to get the server working with the Mac Pro server, as it seems to make sense to use the horsepower I've got to do the encoding editing - trying two options at the moment running Ubuntu under OSX (problem with scripts to interface with ffmpeg compiled using Darwin Ports), and under XAMPP for OSX... do you know of anyone else trying to run Kaltura on OSX?

Hi David,
I also love the idea of having an application that can convert Kaltura SDLs to Final Cut Pro XMLs or Avid EDLs and vice versa!
I have been meaning to start work on such a script for a while now, but still haven't got around to it.
Please keep us all posted on your progress! If I magically find some more free time, and get a chance to play with this kind of functionality, I'll certainly post all the details here.
Good luck getting Kaltura to work on a Mac! I'll certainly be following your progress with great interest!
Best Regards, Chris!

hmm.. we have bunch of ppl using Mac too.
However, we had to release Linux first and wait with both Windows and OSX.
If the only problem is with FFMPEG, maybe you can get an already compiled version and try to set up the links yourself..
Some examples of compiling FFMPEG on OSX -

Thanks for your reply! Good to know there are some people using OSX. Would be great to hook up with them, and get hold of a GIT or SVN based version - to make it easier to keep up to date.
I've been trying a number of options XAMPP on OSX, and the built in server - but moved over to using MacPorts and installing everything from there. Got ffmpeg recognized. I've posted to a few threads on this - so to avoid confusion would like to move over to a wiki - where I document the specifics of my installation / set-up issues - ie LAN based network, integration with Final Cut XML, and OSX based server.
At the moment I'm getting a problem with recursion for the links (I entered an IP/path for the :
Your KalturaCE Server Is Only Partially Functional
6 services are down - go to the Server Monitor to learn more
Clicking on "server monitor" (http://192.168.120.199/kalturaCE_v0.9/index.php/kmc?tab=server) - leads to the recursive url "http://192.168.120.199/kalturaCE_v0.9/index.php/install/install/install/install...."
I've attached a log file: my guess is its going wrong here:

David,
do you have mod_rewrite enabled ? does your kalturaCE folder allowed to have .htaccess file ?
the .htaccess file supplied with the kalturaCE contains some rewrite rules, if your apache doesn't allow the use of .htaccess file (or don't have mod_rewrite enabled) those rewrite rules will not work and that's probably why you get the recursion.
Hi david, welcome :)
The server enables any kind of specific enconding / transcoding. This is done by changing the parameters yourself on the database or using the pre-defined profiles on the KMC.
The sizes are set from the KMC too and are accessible later.
EDL is represented as an SDL (Sequence Description Language) that we defined in Kaltura, both the Editors and the Players read this SDL at run-time to produce video. The quality of the content depends on the conversion you made, if you're using a local network, use better a conversion and the rest will work the same.
