I need 147Gb of free space, but my home directory on gcc.gnu.org only has 117Gb.

overseers, any way to create room somewhere on sourceware for me to
upload the 2013 videos?

Given that the converted videos would probably take up a similar amount of 
space to the originals to have a similar quality (and until the MP4 
patents all expire - around 2027, apparently, by which time 147Gb may be a 
negligible amount of space - we'll want both the originals and the best 
available unencumbered format), maybe we should ask gnu-prog-discuss what 
the best place is for hosting large amounts of high-quality GNU-related 
video?  The issue can hardly be unique to the Cauldrons.

(The above assumes the originals are MP4 or some other patent-encumbered 
format.  If an unencumbered format there's no real point in converting 
unless the result of conversion is much smaller than the original - which 
might well be the case if the original format is one that only compresses 
individual frames, such formats also being more likely to be 
unencumbered.)

FWIW, it seems

http://audio-video.gnu.org/

is official GNU hosting for videos.  But I don't know if they'll archive 
the original files for later conversion to future unencumbered formats, 
and of course you still need somewhere to put the 147Gb of files to get 
them to the audio-video people.  I suppose it may be worth filing an issue 
in http://savannah.gnu.org/task/?group=audio-video explaining what files 
you have and asking how to provide them.

We should be able to assume that having videos hosted there (possibly in 
addition to other places) is sufficient for GNU purposes (if that project 
is provided with the source material in as good a quality as provided to 
some other site, I hope they will ensure they provide the video in an 
unencumbered format and readily accessible with only free software with 
quality as good as on the other site).
