* To track new releases, take a look at [[http://freecode.com/projects/video-contact-sheet/|its Freecode page]].
* Requirements (most desktops should have all, or most, of them): [[http://www.imagemagick.org/|ImageMagick (at least version 6.3.5-7)]] (convert, montage and identify commands), [[http://mplayerhq.hu/|mplayer]] or [[http://ffmpeg.mplayerhq.hu/|FFmpeg]] (preferably both), and some common stuff available on most sane desktops: bash (≥ 3.1) (for bash v2.05b use vcs 1.12.2), sed, grep/egrep, getopt and cut.\\ DVD support (optional) requires [[http://untrepid.com/lsdvd/|lsdvd]] and perl.
* Slightly buggy :P
* Any contribution, suggestion or bug report is welcome.

===== Description =====
This is a bash script meant to create video contact sheets (previews) of videos. Any video supported by mplayer and ffmpeg can be used.
A note of warning: Unlike most similar tools it, by default, makes screenshots the same size as the video, see below for details on how to change this.
Take a look at the [[vcs:docs|documentation]] and/or use the ''--help'' and ''--fullhelp'' options to learn how to use it.
==== Notes ====
* Using ''-i'' or ''-n'' with values that lead to the same number of vidcaps doesn't necessarily yield exactly the //same// vidcaps, you'll have to play with them for best results.
* Example: With a video that lasts for 22min 14secs, ''-n 6'' will create the six vidcaps:\\ 3:22, 6:44, 10:04, 13:28, 16:50 and 20:12, while ''-i 3m'' will create 3:00, 6:00, 9:00, 12:00, 15:00 and 18:00.\\ As you can see, ''-n'' distributes the vidcaps all over the video while ''-i N'' starts at ''N'' and goes in increments of it up to the end.
* You can set the aspect ratio of the video with ''-a''. It is only required for anamorphic material and discouraged for the rest.\\ It can take either a floating point number (like ''1.33'' or ''1.778'') or a fraction (like ''4/3'' or ''16/9''). The latter is slightly preferable.
===== Default behaviour =====
By using configuration files and/or command line options the default behaviour can be tweaked to your needs, these are the defaults, followed by a link with the explanation on how to change it:
* Captures are made every 5 minutes. See //[[vcs:docs:usage]]//.
* Captures are the same size as the input video. See //[[vcs:docs:usage#capture_size_and_aspect_ratio|Size and aspect ratio]]//.
* Captures are arranged in 2 columns (if there's more than one capture). See //[[vcs:docs:usage#number_of_columns|Number of columns]]//.
===== Documentation =====
[[vcs:docs|Documentation has been moved to a separate set of pages]].

More samples can be found in the documentation pages, e.g. in: [[vcs:docs:samples]], [[vcs:docs:example_configs]], [[vcs:docs:colours]].
===== Known Issues =====
* Getting stuck on first frame
* This happening is a sign that the decoder (FFmpeg or MPlayer) has problems dealing with the input file. Interrupt with CTRL+C and re-run with ''-O stderr=/dev/stderr'' to display decoder errors. It might be due to unsupported codecs or broken files, there's little more you can do, except trying with the other decoder (''-M'' to use MPlayer, ''-F'' to use FFmpeg, which is the default).
* Getting gray frames
* This is a decoder error (either due to a broken file or some codec bug). Again little to be done other than switching decoders.
Remember this is a (neverending) work in progress, please report any bugs you encounter, either through e-mail or the [[https://b.outlyer.net/vcs/|bug tracker]].
