Batch Processing

Batch processing allows one to queue up large numbers of tasks and process each
one automatically without the user's intervention. This is especially useful if you intend
to do a lot of conversions but don't want to sit around waiting for one task to finish... just
to set up the next one.

With RAR support and multi-volume archiving in 15,000,000 and 20,000,000 bytes,
video distribution is considerably easier in VCDGear. Any task in the VCDGear or
VideoCD sections can be queued up. External programs/batch files can also be
added to the queue for execution.

Each task added to the batch processor list has its own independent error handling.
For example, you can tell Task #10 to stop on ALL errors but Task #1 to #9
to continue regardless of errors.

STEP 1

A task can be opened or saved from a file. Clicking on the [task] button will show you the
options for that. A third option will also be available and this will open the batch
processor (batch list).

To Save Task Project, you need to have everything set up -- the input and output filenames,
the extraction/conversion type, etc... If Save Task doesn't do anything when you click on it,
it means that you must have left out something.

Tired of going to Save Task Project, entering a filename to save task file, clicking on OK,
then adding it into the batch processor (see below)? The ===> button makes a temporary
task file and automatically queues it into the batch processor... saving you a bunch of
clicks and keystrokes!

The batch processor holds the list of queued tasks. Tasks can be added/moved/deleted
from the queue at any point. Clicking on [add task] will bring up the Task Properties screen.

STEP 2

A task is split into 2 areas: the Task Type and Error Handling. You can queue a task
file that you just saved in either the VCDGear page or VideoCD page. You can also
RAR up specific files or all output files generated by previous task! Automatic
unRAR and Delete RAR options can be queued, and user command line.

WARNING: Delete RAR archive has been known to delete your files EVEN if the
decompression failed. This is due to a bug in WinRAR v2.80 which tells VCDGear
that everything went fine (and poof.. files are gone!). I have spoken with the author
on this bug and he said it will be fixed in v2.90. Use the latest version of WinRAR
and be cautious.

I am not responsible for loss of archive files in any way so don't say I didn't warn you :)

STEP 3

Select the Error Handling types. Queries in VCDGear are the message prompts that ask
YES/NOl. This type of prompt can appear when (for example) VCDGear believes
that you may not have enough disk space to run a certain task.

STEP 4

If you are not Adding to RAR, you can skip this step.

Archiving with a volume size and amount of compression (0% means no compression) can
be done in the Archiving Options section. If you choose 15/20mb for the volume size, do
not specify the -v parameter in the Compression Parameters of the VCDGear Configuration.
VCDGear will automatically add it in for you.

To specify your own volume size not listed in VCDGear, select None. In the VCDGear
Configuration under Compression Parameters, add the necessary volume size parameter.

STEP 5

Click OK to get out of the Task Properties. Your task should now be listed in the Batch
Processor. You can right-click on a task to edit its properties at any point in time.

Click [start] to begin running all queued tasks! If a task dies and you don't know why,
check the Log page.
