Typically, a Blu-ray Disc has a 25 GB capacity and can hold 135 minutes of high-definition video using MPEG-2 plus 2 hours of standard
definition bonus material, or it can hold a total of 10 hours of standard-definition content. Blu-ray Discs come in BD-R (recordable) and BD-RE
(rewritable) formats.
Premiere Elements supports single-layer, 4.7 GB DVDs of the following types: DVD+R, DVD+RW, DVD-R, and DVD-RW. It also supports
dual-layer 8.5 GB DVD+R discs. Choose the media supported by both your DVD burner and the DVD player on which you plan to play the DVD.
Not all DVD burners and DVD players support all types of DVDs. For example, many, but not all, TV DVD players recognize DVD+R discs.
This format uses write-once recordable discs, and is compatible with both stand-alone DVD players and DVD-ROM drives. DVD-R discs
are available in two media types: General Use and Authoring. Most consumer DVD-R burners use the cheaper General Use discs, and some
professional burners use Authoring discs. You must use the correct media type for your burner. However, once written, the discs should be
readable in either type of DVD player or drive. (General Use DVD-R is designed to prevent backup of encrypted commercial DVDs.)
This non-rewritable format is compatible with most DVD players and DVD-ROM drives. The first generation +RW burners did not support
DVD+R recording, and probably cannot be upgraded to do so. However, all current models of DVD+RW burners support DVD+R recording.
Compatibility of DVD+R discs in stand-alone DVD players is similar to that of DVD-R.
These formats are similar in functionality and compatibility with DVD burners and players. DVD-RW and DVD+RW use
rewritable discs that can rewrite more than 1000 times in ideal situations. The majority of stand-alone DVD players play video recorded on
DVD-RW and DVD+RW discs, but the compatibility is not as high as with DVD-R and DVD+R. Current DVD-RW burners can also burn to DVD-R.
If your DVD burner is not compatible with Premiere Elements, you can burn the project to a folder, which allows you to use the software
included with the burner to burn the final DVD.
Compatibility issues for DVDs
When choosing media and hardware, consider the following compatibility issues:
The DVD+R and DVD-R formats are compatible with more set-top players than DVD+RW and DVD-RW.
DVD-ROM drives are compatible with more DVD formats than set-top DVD players, often because computers can update firmware and
drivers easier than a set-top player.
Older DVD players support fewer DVD formats.
Select the preset for a given format in accordance with the available space on the target medium and the needs of the target audience.
Video encoding for DVDs and Blu-ray Discs
Making a DVD or Blu-ray Disc involves encoding your video into the MPEG-2 format or the H.264 format (Blu-ray only). Compression reduces
your video and audio files to take up less storage space. For example, a 60-minute video in Premiere Elements takes up approximately 13 GB.
However, a single-layer DVD holds only 4.7 GB. (Dual-layer DVDs hold 8.5 GB.) To maintain maximum quality, Premiere Elements compresses
the movie only as much as necessary to fit it on the disc. The shorter your movie, the less compression required, and the higher the quality of the
video on the disc.
The Blu-ray presets are suitable for exporting AVCHD-quality files.
Compressing video and audio for use on a disc is very time consuming, even on high-end, dedicated systems. The time required varies depending
upon the speed of the computer processor, the amount of available memory, and the complexity and length of a project. A standard video project
of 60 minutes may take from 4 to 6 hours to burn. Many DVD and Blu-ray Disc producers burn a project overnight.
The Blu-ray format H.264 is computationally intensive and, hence, takes a long time to encode. However, the compression is high and
allows more video data per MB. MPEG-2 is not as computationally intensive, so it is faster, but the amount of video information per MB is less.
