  válasz Lauda #5613 üzenetére

  DVD-nél standard felbontások vannak -legalább is a következők közül tudsz választani (Wikipediáról (angol):

  DVD-Video can consist of either MPEG-2 at up to 9.8 Mbit/s (9800 kbit/s) or MPEG-1 at up to 1.856 Mbit/s (1856 kbit/s).
  
  The following formats are allowed for MPEG-2 video:
  
  * At 25 fps (usually used in regions where PAL is standard):
  
  720 × 576 pixels MPEG-2 (Called full D1)
  704 × 576 pixels MPEG-2
  352 × 576 pixels MPEG-2 (Called Half-D1, same as the China Video Disc standard)
  352 × 288 pixels MPEG-2
  
  * At 29.97 or 23.976 fps (usually used in regions where NTSC is standard):
  
  720 × 480 pixels MPEG-2 (Called full D1)
  704 × 480 pixels MPEG-2
  352 × 480 pixels MPEG-2 (Called Half-D1, same as the China Video Disc standard)
  352 × 240 pixels MPEG-2
  
  The following formats are allowed for MPEG-1 video:
  
  * 352 × 288 pixels MPEG-1 at 25 fps (Same as the VCD Standard)
  * 352 × 240 pixels MPEG-1 at 29.97 fps (Same as the VCD Standard)

  Kép akadásra:
  
  DVD-Video discs have a raw bitrate of 11.08 Mbit/s, with a 1.0 Mbit/s overhead, leaving a payload bitrate of 10.08 Mbit/s. Of this, up to 3.36 megabits can be used for subtitles and a maximum of 9.80 megabits can be split amongst audio and video. In the case of multiple angles the data is stored interleaved, and so there's a bitrate penalty leading to a max bitrate of 8Mbit/s per angle to compensate for additional seek time. This limit is not cumulative, so each additional angle can still have up to 8Mbit/s of bitrate available. Professionally encoded videos average a bitrate of 4.0-5.0 Mbit/s with a maximum of 7–8 Mbit/s in high-action scenes. This is typically done to allow greater compatibility amongst players, and to help prevent buffer underruns in the case of dirty or scratched discs.
  

  A hang akadásra nem tudok mit mondani.
