We also discovered a problem with long presentations with lots of slides in a late 1.3 beta - I think it may affect 1.2 (it was fixed for the 1.3 release). Basically when the workflow gets to create the segmented video it requests the md5 sum of the file * the number of segments. The md5 was being calculated (it wasn't stored) causing the cp on the admin node to max out and the service to become unresponsive ...

by "have been build with the

In some cases there are problems with files bigger than 2GB. Sometimes those
errors are avoidable, sometimes aren't. I corrected myself a couple of bugs
in the WorkingFileRepository service (I think that was the part, but at
least it was related), which directly affected the processing of videos
(trimming them to 2GB if they were bigger). This is fixed in trunk, but did
not make it to 1.3 .

I wonder which version are you using and if *all* the machines in your setup
use a shared drive to process the videos (and have been build with the
workspace --rather than the workspace-stub -- profile).

We have a professor here who utilizes Powerpoint presentations with
large numbers of slides and imbedded in the presentations are youtube
videos, so the track for the presentation video is quite large, 1.2
gigs on average.  Several of her captures have failed during
processing and reingestion fails and the mpg for the presenter
computer is blamed.  The last two lectures for this class processed
just fine but the last 10 minutes of one lecture and the last 5
minutes are not viewable, the video freezes and the audio along with
it.  These lectures are an hour and 15 minutes.  Have we hit some
threshold?
