Re-Authoring a Job
Before starting a job at the authoring stage, it may be useful to understand the job file data and work directory items
needed. Before going into this however, please make sure you read the page on Re-Running Part of a Job.
There are two occasions when a job is started at the authoring stage by pressing the silver button under 'Author'.
1. Re-authoring a job that has been previously captured with DVD-100. The job may even have been
completed but if changes to the menu are desired, the DVD can be authored again. The original chapters
and thumbnails chosen during the capture stage will still be used unless custom chapters are specified.
2. Starting a job at the authoring stage when pre-encoded files are being used rather than starting with realtime
capture and encoding. See Pre-Encoded Files Property Page for further discussion on the use of pre-
encoded files. If this is the case, a determination will be made based on the job settings whether chapter
selection is needed before authoring. In addition to selecting DVD chapters, this process also captures
bitmaps to use for DVD menus and case wrap printing as well as determining the lengths of the pre-encoded
segments. If chapters, bitmaps and segment lengths are not required, the chapter selection will not be run.
If the chapter selection is required, it can take as much as 30% of the video's time to finish. (If the video is
one hour in length, the chapter selection could take as much as 20 min)
In order to be able to author the DVD, the job file must point to the audio and video elementary streams. These
would have been produced by the video capture stage. These files should be located in the directory: <working
directory>\<JobID>. If producing a DVD with chapters, the video capture stage would also have identified
candidates for chapter starting points and thumbnail bitmaps of those frames. The quantity and frame number for
each of those potential chapter starting points must be found in the job file in order to successfully author the DVD.
The thumbnail bitmaps are stored in the same working directory as the elementary streams.
Finally, the job can be re-authored by clicking on the Author button above when the display tab is either on the
Setup or Author page. It is important to note that when re-authoring from the Setup display page, the above-
mentioned prerequisites apply to the current job. If re-authoring from the Authoring display page, the last authored
job will be re-authored.
Re-Printing a Job
Before starting a job at the printing stage, it may be useful to understand the job file data and work directory items
needed. Before going into this however, please make sure you read the page on Re-Running Part of a Job.
In order to be able to print the DVD print assets, the job file should contain the running length of the DVD which
would have been determined in the video capture stage. If printing the case wrap with thumbnail pictures, the
bitmaps must be found in the directory: <working directory>\<JobID>. When printing, the chapter insert, the starting
point and length of each chapter is needed. This information is produced by the video capture and authoring
stages.
Finally, the job can be re-printed by clicking on the Print button shown above when the display tab is either on the
Setup or Print page. It is important to note that when re-printing from the Setup display page, the above-mentioned
prerequisites apply to the current job. If re-printing from the Print display page, the last printed job will be re-printed.
