kort om olika DVD-format (på engelska)
Different format includes DVD-R, DVD-RW, and DVD+RW. A 30 min 1.4GB DVD-R disc comes included in the box. Parsing the differences between formats can be difficult for beginners and even for regular camcorder users. We’ll try and give you a quick breakdown here.
DVD-R is the simplest format. The discs are one-time use only, and available in more than one capacity. You record until it’s full, and then you pop it into a playback device (home DVD player, computer, or the camcorder itself) and watch the footage. DVD-R does not allow erasing, but it is the most universally recognized format, so most every type of playback device will accept it. You do need to finalize the disc before playing it elsewhere.
DVD-RWs are a fixed capacity of 4.7 GB, and can be rewritten about 1000x over. Within the DVD505, there are two recording modes for the DVD-RW, which can be selected in the menu: VR and Video. Stay with me now; it’s gets a little complicated. In the DVD-RW VR mode, you can delete or edit stills and video clips at any time in the camcorder. You must finalize the disc in order to play VR footage back on other devices, but, the manual indicates, that device must be DVD-RW VR compatible. Be sure to check your playback device before using this recording mode. If you have space left on the disc, the VR format allows you to pop it back in the camcorder and record more footage without unfinalizing.
The other DVD-RW mode, Video, only allows you to delete the last clip you recorded. Finalizing a disc in this mode will allow it to play on most DVD devices. When you want to use it again, you must unfinalize the disc.
The third media choice is DVD+RW. DVD+RW discs do not necessarily require finalizing, though it may be necessary for certain purposes, which Sony lists as: creating DVD menus or Photomovies, playback on computer DVD drives, or when little is recorded on the disc (5 minutes of HQ, 8 minutes of SP, and 15 minutes of LP). +RW supports random write access, meaning that data can be added or deleted without wiping the entire disc. In the camcorder, however, you can only delete the last clip you recorded when using DVD+RW. Again, compatibility is not guaranteed for any playback device, so check the specs before you commit important footage to any format.
