3 title: Video Timeline Setup
7 No configuration is required if you intend to run everything on a single
8 machine, and if you acquired Ardour from
9 <a href="http://www.ardour.org"
10 title="http://www.ardour.org">http://www.ardour.org</a>.
11 Everything is pre-configured and included with the download/install.
14 <h2>Single Machine</h2>
16 If you compile Ardour from source, or have installed it from a 3rd party
17 repository, three additional tools will need to be installed manually,
18 which are used by Ardour to provide video features:
21 <li>xjadeo (the video monitor application): <a href="http://xjadeo.sf.net"
22 title="http://xjadeo.sf.net" rel="nofollow">http://xjadeo.sf.net</a></li>
23 <li>harvid (a video decoder used for the thumbnail timeline): <a
24 href="http://x42.github.com/harvid/" title="http://x42.github.com/harvid/"
25 rel="nofollow">http://x42.github.com/harvid/</a></li>
26 <li>ffmpeg, ffprobe (used to import/export video, extract soundtracks and
27 query video information): <a href="http://ffmpeg.org" title="http://ffmpeg.org"
28 rel="nofollow">http://ffmpeg.org</a></li>
31 Ardour requires xjadeo ≥ version 0.6.4, harvid ≥ version 0.7.0 and ffmpeg (known to work versions: 1.2, 2.8.2)
35 The Ardour development team is in control of the first two applications. ffmpeg
36 however can be a bit of a problem. To avoid conflicts with distribution packages,
37 Ardour looks for <code>ffmpeg_harvid</code> and <code>ffprobe_harvid</code>.
40 All four applications need to be found in <code>$PATH</code> (e.g.
41 <code>$HOME/bin</code> or <code>/usr/local/bin</code>). For convenience the
42 binary releases of harvid include ffmpeg_harvid and ffprobe_harvid, but if
43 your distribution provides suitable ffmpeg commands you can also just create
46 <kbd class="cmd lin">sudo ln -s /usr/bin/ffmpeg /usr/bin/ffmpeg_harvid</kbd>
47 <kbd class="cmd lin">sudo ln -s /usr/bin/ffprobe /usr/bin/ffprobe_harvid</kbd>
49 Binary releases are available from ardour.org as well as an installer script:
50 <a href="https://github.com/Ardour/ardour/blob/master/tools/videotimeline/install_video_tools.sh"
51 title="https://github.com/Ardour/ardour/blob/master/tools/videotimeline/install_video_tools.sh"
52 rel="nofollow">install_video_tools.sh</a>.
55 The easiest way to install the video-utilities is by running the following
58 <kbd class="cmd lin">sh -c "$(curl -s -L http://git.io/tVUCkw)"</kbd>
62 Please read the info in the previous section to familiarize yourself with
63 the tools involved first. Setting up a proper A/V post-production studio
64 can be a complicated task. As much as we streamline and simplify the
65 <em>single machine</em> setup, the <dfn>studio setup</dfn> is focused on modularity.
70 <li>Synchronization ardour → video-display-box should be accomplished by external
71 means jack-transport(netjack), MTC, LTC
72 (<abbr title="Open Sound Control - "postmodern MIDI"">OSC</abbr> and/or
73 ssh-pipe work but introduce additional latency + jitter)</li>
74 <li>Ardour launches <code>XJREMOTE</code> (environment variable, default 'xjremote' which comes with xjadeo).
76 <li>Either use a custom shell script that ssh'es into the remote box and launches/controls xjadeo there, selects the sync-source and passes though communication between ardour ⇔ xjadeo via ssh (xjadeo is launched stopped with the session).
78 <li>..or override xjremote's behavior – instead of IPC with a local running xjadeo-process, using <abbr title="Open Sound Control - "postmodern MIDI"">OSC</abbr> for example. xjadeo would run permanently and Ardour will just tell it to load files and set offsets via <acronym title="Open Sound Control - "postmodern MIDI"">OSC</acronym>. see <a href="http://xjadeo.git.sourceforge.net/git/gitweb.cgi?p=xjadeo/xjadeo;a=blob_plain;f=contrib/xjremote-osc" title="http://xjadeo.git.sourceforge.net/git/gitweb.cgi?p=xjadeo/xjadeo;a=blob_plain;f=contrib/xjremote-osc" rel="nofollow">xjremote-osc</a> example script.
80 <li>If the video server runs remotely, Ardour needs to be configured in Ardour > Preference > Video (hostname of the video-server).
83 Ideally the machines have a common shared folder (NFS or similar). Ardour's import (audio-extract) and export (mux) functionality depends on having access to the video file. Also Ardour's video-import transcodes the file into a suitable proxy-format that allows reliable seeking to any frame…
