NAME

       sreview-cut - cut a talk out of the raw recording data

SYNOPSIS

       sreview-cut TALKID

DESCRIPTION

       "sreview-cut" performs the following actions:

       •   Look up the talk with id TALKID in the database.

       •   From the raw files, extract the amount of video that, according to the schedule, is
           part of the talk of which the event was given as the main video (with adjustments as
           specified by the reviewer, if any, applied).

       •   Extract the 20 minutes just before and the 20 minutes just after the main video into
           the pre and post videos.

       •   Apply A/V sync correction values if any exist by removing either some video or some
           audio from the beginning of the extracted region.

       •   Run "bs1770gain" over the audio of the main video, and re-integrate it with that main
           video.

       •   Set the "progress" field of the talk in the database to "done", provided its "state"
           field is still at "cutting".

       sreview-cut will never re-encode the original video, and will re-encode the original audio
       of the main video precisely once, after the "bs1770gain" call.

       Any re-transcodes should be performed by "sreview-transcode" (for production) and/or
       "sreview-previews" (for reviewers).

CONFIGURATION

       "sreview-cut" considers the following configuration values:

       workdir
           The location where any temporary files are stored. Defaults to "/tmp", but can be
           overriden if necessary. These temporary files are removed when "sreview-cut" finishes.

       dbistring
           The DBI string used to connect to the database.

       pubdir
           The directory where files available to the review system should be stored. It should
           be made available to users as "/video/" under the virtual host top level.
