New page
== Video Tools ==

=== Non-finalcut capture path===

* FireWireSDK capture utility to m2t file

* m2t to mov: 

<code>ffmpeg -i ocean_hdv_ca_200903_200911.m2t -f mov -vcodec copy -acodec copy ocean_hdv_ca_200903_200911.mov</code>

*

=== High Resolution Video ===

* 24P workflow with open source tools [http://eugenia.gnomefiles.org/2007/07/13/canon-hv20-24p-pulldown]

* HDMI capture card (BlackMagic Intensity) [http://www.blackmagic-design.com/products/intensity/]

* PCI-Mini and BlackMagic card solution on MBPro [http://panocamera.com/blog/?cat=3]



=== Sub-titles and Closed- Captioning===

[[subtitle manipulation]]



=== VIDEO CONVERSION ===

* ffmpeg command reference http://linux.die.net/man/1/ffmpeg



* <code> ffmpeg -i infile.avi -vcodec mpeg4 -b 8000k outfile.mp4 </code>

* drop audio <code> ffmpeg -i infile.avi -vcodec mpeg4 -an -b 8000k outfile.mp4 </code>

* resize to youtube preferred HD <code> ffmpeg -i infile.avi -vcodec mpeg4 -s 1280x720 -b 8000k outfile.mp4 </code>

* youtube recommendations http://www.youtube.com/t/howto_makevideo

* vimeo http://www.vimeo.com/help/compression



=== VIDEO -> FRAMES ===

* <code> ffmpeg -i infile.avi -s 720x480 -f image2 infile-%03d.tga</code>

* <code> ffmpeg -i toiletpaperhead\ wind.mov -deinterlace -r 0.5 -an -y -vcodec mjpeg -f image2 -sameq /Volumes/Reservoir/Frames/toilet_0.5/toiletpaper_wind_0.5_%05d.jpg</code>

=== FRAMES -> VIDEO ===

<code> ffmpeg -i /Volumes/Reservoir/Frames/toilet_0.5/toiletpaper_wind_0.5_%05d.jpg \

-r 30 -vcodec mpeg4 -an -b 4000k toiletpaper_wind_0.5.mp4

</code>



* Force input framerate to 8 fps, output framerate to 30fps:

<code>

ffmpeg -r 8 -i dfsp%04d.tif -r 30 -vcodec mpeg4 -an -b 24000k dfsp03.mp4

</code>



*imagemagick to crop/convert images:



<code>

convert '*.tif' -resize 1280x720 resized/dfsp%04d.tif

</code>



<code>

convert -verbose 'dfsp01_%04d.tif'[1-500] -resize 1280x720 resized/dfsp%04d.tif

</code>



*converting through python script

<source lang="python">

from subprocess import call



import sys

for i in range(751,6992):

    try:

        cmd = "dfsp01_%04d.tif -resize 1280x720 /Volumes/Reservoir/Process/dfsp/dfsp%04d.tif"%(i, i)

        print "convert " + cmd

        retcode = call("convert " + cmd, shell=True)

        if retcode < 0:

            print >>sys.stderr, "Child was terminated by signal", -retcode

        else:

            print >>sys.stderr, "Child returned", retcode

    except OSError, e:

        print >>sys.stderr, "Execution failed:", e



</source>



* downsizing 4k frames to HD 1080p (using imagemagick):

 imconvert scstereo_01628.tif -geometry 1920x1080 small.tif

* joining left and right frames to make single-frame images (with python and imagemagick <code> montage </code> command):

<source lang="python">

 from subprocess import call

 

 import sys

 for i in range(0,5856):

    try:

        cmd = "-geometry +0+0 left/scstereo_left_%05d.tif right/scstere_right_%05d.tif -depth 8 joined/wide_1080p_%05d.tif"%(i, i, i)

        print "montage " + cmd

        retcode = call("montage " + cmd, shell=True)

        if retcode < 0:

            print >>sys.stderr, "Child was terminated by signal", -retcode

        else:

            print >>sys.stderr, "Child returned", retcode

    except OSError, e:

        print >>sys.stderr, "Execution failed:", e



</source>

=== TIMELAPSE ===

<code>



ffmpeg -r 1 -i %04d.jpg -vcodec mjpeg -qscale 1 -s 1440x1080 -an output_1080.avi



</code>



=== Misc ===

[[ffmpeg to make a dvd]]
