Compiling and formatting your 3D disc
Compiling
When you compile your Blu-ray Disc with a 3D Playlist, DoStudio Authoring will automatically create an
ISO that you can burn to a BD-R/RE or mount and play back on a softplayer. The ISO will be found in your
.BD folder's 3DISO folder.
You can compile your 3D project to a 2D Blu-ray Disc by choosing Compile > Compile 2D Blu-ray Disc. You
can also click the Compile 2D Blu-ray Disc button the toolbar or press Shift+F6. Compiling your 3D project
to a 2D Blu-ray Disc takes less time than compiling to a 3D disc, giving you more time for testing.
For more information, see "Compiling your Blu-ray Disc" on page 167.
Formatting
When you are ready to format your disc for replication, DoStudio Authoring will not create the ISO and will
do the same steps as a 2D disc.
For more information, see "Formatting your Blu-ray Disc for replication" on page 175.
3D metadata offset file (.ds3d)
The .ds3d ASCII text file is used to position subtitles on the screen. Subtitles can appear at a fixed 3D depth,
or they can move in 3D space as the video plays. Each line is treated as separate input line. Blank lines are
allowed, and comments are allowed at the START of the line by using the pound key (#).
The .ds3d text file is based on a sequence of depth offsets for duration of frames as seen below.
For every duration of frames (DOF), there must be the same number of offset sequences (NOS). In the
preceding example, there are 3 offsets. This means that it is important to group the various changes in
depth into equal numbers. For example, if we have a 2 minute, 24 fps video and there are 100 different
offset depth values, we can group the offsets into 10 NOS every 288 frames: 120 seconds x 24 frames per
second / 100 = 288 frames.
Each NOS is a positive or negative number indicated by + or – without a space between the number. For
example, +1 would move a subtitle in front of screen depth, and -3 would move a subtitle behind screen
depth.
The .ds3d file doesn't include any information that points directly to the .dost file. The reason for this is that
the two are completely independent, allowing for subtitle playback on 2D and 3D players.
