to DVD Video Recording Formats
Info provided by CyberLink!
Looking at the current DVD trend, the two major usage for recording on DVDs are Data Backups and Video Recording. With the massive storage space available on a DVD, it is easy to back up a great deal of data and is ideal for producing DVD movies, due to MPEG-2's large file size. But one problem with DVD burning is that the process is relatively slow; especially in comparison to CD burning. As well, because DVDs can hold up to 4.7 GB worth of data, it is unlikely that the average person will use up all of that capacity at one time. So this brings us to the new DVD Video Recording (VR) format. A format which gives you the flexibility to produce fully editable DVD movies!
What is DVD VR and What can you do with it?
In short, DVD VR is a format that enables you to produce a DVD movie that can be edited. A DVD produced in VR format will allow you to add new video contents, change menu backgrounds, insert chapters, split video clips and even remove unwanted video segments (as long as you have enough space available on the disc). And as more DVD authoring applications are adopting the new VR standard, like CyberLink's PowerProducer 2, you will be able to easily record, edit, and playback your DVD movie creations.
So now, using products like PowerProducer 2, you can reuse your re-writeable DVDs again and again, and add as much content as you want. You can transfer 30 minutes of your travel video onto a re-writeable DVD, and then a few months later you can add another 10 minutes from your next trip onto the same disc. Plus, if you want to change the selection menu to contain a new background image, music, navigation buttons, etc., it can be done with ease.
Where can you find VR Technology
Currently, VR technologies are mainly available on high-end home DVD recorders, where you can record and re-record TV programs without the need to change to a different disc. However, with developments in the software industry, you will be able to use programs like PowerProducer 2 and your DVD burner to perform the similar functions as those high-end DVD recorders.
Limitations for VR Format
However, VR technology does have some limitations to be aware of. When you delete a video segment from the VR disc, it may appear to be deleted from the DVD, but you cannot instantly add-in new contents in the "deleted" space. In other words, your DVD's available storage space will not increase just because you have deleted some contents from it. To clear more space you need to Defragment your DVD disc, using programs like Power Producer 2, which will help you optimize the available disc space.
Another issue with VR technology to make note of is that there are two different video recording standards available today: DVD-VR and DVD+VR. With a DVD-VR disc, created using a DVD-RW burning device, you can only playback the contents on a DVD-RW compatible device, and not on a standard home DVD player. However, with DVD+VR format the discs created can be played on DVD+RW compatible devices "and" home DVD players.
