DV Transcoding Workflow

How you use Compressor to transcode your video into DV Stream format files depends
on how you intend them to be used. The basic steps are listed below.

Stage 1:

Creating a Batch

As with any transcode, you need to start by creating a batch. See

Preparing Compressor

for Transcoding with Custom Settings

for more information.

Stage 2:

Creating Jobs with the Source Video Files

Import the source video files either by dragging them from the Finder to the batch or by
choosing Job > New Job With File.

Stage 3:

Adding Targets with a DV Setting to Each Job

Each of the jobs requires at least one target—in this case the jobs need targets with a
DV Stream setting. If there is more than one job, it is easiest to select all the jobs by
choosing Edit > Select All and then choose Target > New Target With Setting to apply
the same setting to all the jobs.

Stage 4:

Submitting the Batch for Transcoding

Click the Submit button to start the transcode process. See

Creating DV Stream Output Files

Compressor provides the tools you need to encode, and batch-encode, Dolby Digital
Professional (AC-3) audio files.

Dolby Digital Professional format (also known as AC-3) is a very common compressed
audio format for DVD-Video discs. Compressor accepts multichannel sound files in a
variety of formats and gives you complete control over the AC-3 encoding process. Dolby
Digital programs can deliver 5.1-channel surround sound with five discrete full-range
channels (left, center, right, left surround, and right surround) plus a sixth channel for
low-frequency effects (LFE), sometimes known as “the subwoofer.” Another surround
option is Dolby Surround, with four channels (left, center, right, surround). But not all
AC-3 audio is 5.1 surround sound. Dolby Digital Professional is commonly used to encode
stereo files to greatly reduce their file size.

creating surround sound audio files using other output formats.

Note: It’s important to understand that Compressor cannot take stereo audio files and
create 5.1 surround sound from them. If you want to create a 5.1 surround sound AC-3
audio file, you must first create the six channels of audio it requires. This must be done
using other applications outside Compressor.
