Hello Ludovic.

Could you (and possibly others) please confirm that the file is accessible?

I've tried downloading ftp://ftp-upload.gnu.org/incoming/other/conf_stallman_posttraite_cut.ogv from my local machine and from fencepost as well; the directory exists, but I can't seem to read the file:

[luca@sussman /tmp]$ wget ftp://ftp-upload.gnu.org/incoming/other/conf_stallman_posttraite_cut.ogv
--2013-10-15 17:00:25--  ftp://ftp-upload.gnu.org/incoming/other/conf_stallman_posttraite_cut.ogv
           => ‘conf_stallman_posttraite_cut.ogv’

No such file ‘conf_stallman_posttraite_cut.ogv’.

Maybe I'm doing something wrong.  Anyway, at this point it might be quicker for you to just FTP the file to my machine.  I'm sending you instructions by private e-mail.  Thanks a lot.

I've put a new version of the video in ftp-upload.gnu.org/incoming/other/conf_stallman_posttraite_cut.ogv

We have reworked three things:

  • We have removed the constant noise (with audacity)
  • We have made the voice of Richard less "metallic" (again, with audacity)
  • We have cut the video after 1h34mn because the sound was badly captured at the source level.


Best regards,
Ludovic.

Unfortunately, I've checked the source version. It is noisy all along, and the end of the end has issues with the sound as well.

For the noise, I'll try to apply a noise reduction algorithm.

Uploaded the current file as requested by Richard.

Ludovic, please contact us again if you come up with a fixed version; we can replace the file later.

I couldn't fix the file by re-encoding it.

If Ludovic can provide another version I'll upload it; or if you want, I can also upload the current version as it is.  It's acceptable up to some time between 1:48:00 and 1:49:00, for a talk lasting around two hours and five minutes.

Please let me know what to do.

Best regards.

The file might be damaged near the end; I'll have a better look at it tomorrow, on a different computer.  (The talk is audible and understandable before that point).

No promises, but I can try and re-encode the video to work around the break, if that is the problem.  Quality will not improve other that from the damage point on, but it shouldn't become appreciably worse either.

Hello Jeannie, and Ludovic.

Indeed the quality is not perfect (even if the video is still perfectly watchable); it looks and sounds like the file was encoded from an already noisy analog source.

I don't know of any easy way of cleaning-up the video; if Ludovic submits a better version of course we can replace the file.  I'll upload what we have, for the time being.

Regards.
