Create video contact sheets. A video contact sheet is an image composed of video capture thumbnails arranged on a grid.
$ vcsi sample.avi \
-t \
-w 850 \
-g 4x4 \
--background-color 000000 \
--metadata-font-color ffffff \
--end-delay-percent 20
$ vcsi sample.avi \
-t \
-w 850 \
-g 3x5 \
--end-delay-percent 20 \
-o output.png
The above contact sheets were generated from a movie called "Big Buck Bunny".
$ pip install vcsi
vcsi is currently packaged for the following systems:
| Linux packages | |
|---|---|
| Arch (AUR) | https://aur.archlinux.org/packages/vcsi/ |
| Arch (AUR, git master) | https://aur.archlinux.org/packages/vcsi-git/ |
| Gentoo | https://packages.gentoo.org/packages/media-video/vcsi |
Your system is not listed?
$ apt-get install ffmpeg
$ python setup.py install
Running Windows? See the note below.
Download a binary build of ffmpeg from Zeranoe here (e.g. 64bit static): http://ffmpeg.zeranoe.com/builds/
Extract the archive and add the bin directory to your PATH so that ffmpeg and ffprobe can be invoked from the command line.
If you have issues installing numpy with pip, download an already built version of numpy here: http://sourceforge.net/projects/numpy/files/NumPy/
Python modules:
- numpy
- pillow
- texttable
- parsedatetime
Must be in your PATH:
- ffmpeg
- ffprobe

number of pixels spacing captures both vertically and
horizontally (default: None)
--grid-horizontal-spacing GRID_HORIZONTAL_SPACING
number of pixels spacing captures horizontally
(default: 5)
--grid-vertical-spacing GRID_VERTICAL_SPACING
number of pixels spacing captures vertically (default:
5)
-w VCS_WIDTH, --width VCS_WIDTH
width of the generated contact sheet (default: 1500)
-g GRID, --grid GRID display frames on a mxn grid (for example 4x5)
(default: 4x4)
-s NUM_SAMPLES, --num-samples NUM_SAMPLES
number of samples (default: None)
-t, --show-timestamp display timestamp for each frame (default: False)
--metadata-font-size METADATA_FONT_SIZE
size of the font used for metadata (default: 16)
--metadata-font METADATA_FONT
TTF font used for metadata (default:
/usr/share/fonts/TTF/DejaVuSans-Bold.ttf)
--timestamp-font-size TIMESTAMP_FONT_SIZE
size of the font used for timestamps (default: 12)
--timestamp-font TIMESTAMP_FONT
TTF font used for timestamps (default:
/usr/share/fonts/TTF/DejaVuSans.ttf)
--metadata-position METADATA_POSITION
Position of the metadata header. Must be one of
['top', 'bottom', 'hidden'] (default: top)
--background-color BACKGROUND_COLOR
Color of the background in hexadecimal, for example
AABBCC (default: 000000FF)
--metadata-font-color METADATA_FONT_COLOR
Color of the metadata font in hexadecimal, for example
AABBCC (default: FFFFFFFF)
--timestamp-font-color TIMESTAMP_FONT_COLOR
Color of the timestamp font in hexadecimal, for
example AABBCC (default: FFFFFFFF)
--timestamp-background-color TIMESTAMP_BACKGROUND_COLOR
Color of the timestamp background rectangle in
hexadecimal, for example AABBCC (default: 000000AA)
--timestamp-border-color TIMESTAMP_BORDER_COLOR
Color of the timestamp border in hexadecimal, for
example AABBCC (default: 000000FF)
--template METADATA_TEMPLATE_PATH
Path to metadata template file (default: None)
-m MANUAL_TIMESTAMPS, --manual MANUAL_TIMESTAMPS
Comma-separated list of frame timestamps to use, for
example 1:11:11.111,2:22:22.222 (default: None)
-v, --verbose display verbose messages (default: False)
-a, --accurate Make accurate captures. This capture mode is way
slower than the default one but it helps when
capturing frames from HEVC videos. (default: False)
-A ACCURATE_DELAY_SECONDS, --accurate-delay-seconds ACCURATE_DELAY_SECONDS
Fast skip to N seconds before capture time, then do
accurate capture (decodes N seconds of video before
each capture). This is used with accurate capture mode
only. (default: 1)

Margin (in pixels) in the metadata header. (default:
10)
--metadata-horizontal-margin METADATA_HORIZONTAL_MARGIN
Horizontal margin (in pixels) in the metadata header.
(default: 10)

Alpha channel value for the captures (transparency in
range [0, 255]). Defaults to 255 (opaque) (default:
255)
--version show program's version number and exit
--list-template-attributes
--frame-type FRAME_TYPE
Frame type passed to ffmpeg
'select=eq(pict_type,FRAME_TYPE)' filter. Should be
one of ('I', 'B', 'P') or the special type 'key' which
will use the 'select=key' filter instead. (default:
None)

is any string supported by `parsedatetime`. For
example '5m', '3 minutes 5 seconds', '1 hour 15 min
and 20 sec' etc. (default: None)
--ignore-errors Ignore any error encountered while processing files
recursively and continue to the next file. (default:
False)
vcsi now supports metadata templates thanks to jinja2. In order to use custom templates one should use the --template argument to specifiy the path to a template file.
Here is a sample template file:
{{filename}}
File size: {{size}}
{% if audio_sample_rate %}
Audio sample rate: {{audio_sample_rate/1000}} KHz
{% endif %}
{% if audio_bit_rate %}
Audio bitrate: {{audio_bit_rate/1000}} Kbps
{% endif %}
{{frame_rate}} fps
Resolution: {{sample_width}}x{{sample_height}}
