Recording openSUSE Talks

From openSUSE

Equipment

Setting up the location

Post processing the recording

There are different options on how to get the recording from the camera to the PC and how to process it. Our standard workflow for creating video files from openSUSE talks is grabbing with dvgrab and processing with kino and ogmtools. More information about video editing options can be found at Video_editing.

dvgrab

To get a raw dv file on disk, connect the camera with firewire, rewind the tape and grab the recording with (as root):

dvgrab -size 0 dvout

To grab live data from the plugged in camera:

dvgrab -size 0 -noavc dvout

kino

Kino can be installed from Packman (1-click).

import the dv file

cut

apply effects

Make sure the file inputfield on the upper left corner points to your desired output directory (don't forget to add an / at the end of the path).

When the sound level is too low, try to add an audio gain by selecting "Gain" in the audio filter tab and raising the black line.

To add the openSUSE logo overlay to the video, add the "Superimpose" video filter and configure the logo.

export

When kino finds a ffmpeg2theora executable in the path it will automtically offer this as an export option in the export->'other' tab.

KDEnlive

With version 0.7 kdenlive got our tool of choice to create the openSUSE videos. Grab it from Packman (1-click).

You can download the template we used to create the Fosdem 2009 talks with the openSUSE logo in the upper right corner and a startscreen that displays the topic.

As I have problems with exporting ogg files directly from kdenlive, I exported as dv, and then created the .ogv files with ffmpeg2theora.

Publish the media

wiki

Please add talks to the Talks page, for conferences we have dedicated pages, such as Fosdem 2008, Fosdem 2009.

opensuse.blip.tv

Andrew Wafaa started a dedicated openSUSE channel on opensuse.blip.tv. Ask FunkyPenguin or digitltom in irc to get files published there.

The channel uses a slightly modified logo which you can find here. Also interviews are preceded with this coversheet. To use the coversheet edit it as needed, then save to pdf and from there open it in something like the GIMP and save as png.

tube.opensuse.org

To publish new media on tube.opensuse.org we use rsync:

rsync -vtrp . rsync://widehat-opensuse.suse.de/opensuse-tube-push/

Please ask tschmidt if you want some files to be published.

To fetch or mirror data from tube, there is the rsync module: rsync://widehat.opensuse.org/opensuse-tube
