darktable – photography workflow application

February 28th, 2011 No comments

i just stumbled over this nice and free application.

a virtual lighttable and darkroom for photographers: it manages your digital negatives in a database and lets you view them through a zoomable lighttable. it also enables you to develop raw images and enhance them.

this project tries to fill the gap between the many excellent existing free raw converters and image management tools (such as e.g. ufraw, rawstudio, f-spot, digikam, shotwell). The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. the main focus is on user interaction, both in terms of a smooth interface design as well as processing speed. high quality output is also one of our goals.

all editing is fully non-destructive and only operates on cached image buffers for display. the full image is only converted during export. raw image loading is done using libraw and rawspeed, high-dynamic range, and standard image formats such as jpeg are also supported. the core operates completely on floating point values, so darktable can not only be used for photography but also for scientifically acquired images or output of renderers (high dynamic range).

it is amazingly fast compared to other equivalent (but costly) tools like adobe lightroom, apple aperture or bibble labs.

it also has plugins that enhance the funcionality a lot. in my opinion it’s functionally equal to the highcost payware.

try it out!

mythtv userjob handbrake transcode / convert to x264

September 8th, 2010 2 comments

Endlich hab ich eine Möglichkeit gefunden meine über DVB-T mit MythTV aufgenommenen Sendungen automatisch nach x264 zu konvertieren. Die Filme haben danach nur noch ein Drittel der ursprünglichen Dateigröße. Das Script stammt im Original von Defcronyke Webmaster. Ich habe lediglich ein paar Zeilen auf meine Bedürfnisse geändert und benutze zur Konvertierung nicht den mencoder, sondern das HandBrakeCLI da ich mit der Originalversion des Scripts Probleme mit deutschen Umlauten hatte. Lest euch erstmal die Originalquelle des Scripts durch und schaut euch dann meine Version an. Dort wird auch erklärt wie man es in mythtv einbaut. Die Kommentare im Script sind größtenteils aus der Originalversion und in Englisch.

Benötigte Software:

  • MythTV (doh!)
  • HandBrakCLI

WICHTIG: Benutzung auf eigene Gefahr. Ich übernehme keine Garantie für die Funktionalität oder irgendwelche Schäden die bei der Benutzung des Scripts entstehen.


# mythtv multi-pass auto-transcode to x264 with HandBrakeCLI, remove commercials, and delete original recording bash script
# This Script is copyright © 2010 Defcronyke Webmaster, The Eternal Void Network. 

# variables
# $1 must be the directory/file to be transcoded. (in mythtv enter: "%DIR%/%FILE%")
# $2 must be the output directory / file name. The directory must be writeable by the mythtv user (in mythtv enter: "/path/to/output-dir/%TITLE% - %PROGSTARTISO%.mkv")
# $3 must be chanid (in mythtv enter: "%CHANID%")
# $4 must be starttime. (in mythtv enter: "%STARTTIME%")
# full userjob command should look like this: /path/to/this-script/ "%DIR%/%FILE%" "/path/to/output-dir/%TITLE% - %PROGSTARTISO%.mp4" "%CHANID%" "%STARTTIME%"

# a temporary working directory (must be writable by mythtv user)

# MySQL database login information (for mythconverg database)

# MythTV Install Prefix (make sure this matches with the directory where MythTV is installed)

# go to correct working dir

# remove commercials
$INSTALLPREFIX/mythcommflag -c "$3" -s "$4" --gencutlist
$INSTALLPREFIX/mythtranscode --chanid "$3" --starttime "$4" --mpeg2 --honorcutlist
$INSTALLPREFIX/mythcommflag --file "$1" --rebuild

# handbrake converting
HandBrakeCLI -e x264  -b 1000 -a 1 -E faac -B 128 -R 44.1 -6 dpl2 -f mp4 --crop 0:0:0:0 -d fast -p -m -2 -T -x ref=2:bframes=2:me=umh -i "$1" -o "$2"

# uncomment the following 6 lines to delete the original recorded show, associated picture files, and remove entry from database (make sure everything else works properly before trying this)
#rm $1
#rm $1.100x75.png
