DVEdit

Tech specs

  • Chroma subsampling: DV or MiniDV(NTSC) = 4:1:1
  • Chroma subsampling: DV or MiniDV(PAL) = 4:2:0

DVcamEdit

XDCAMEdit

Recording DVcam onto optical disk

DVCpro, DVCpro50 and DVCproHDEdit

Panasonic's formats.

They all use exactly the same tape medium but the tape runs faster through the mechanism for the higher quality formats.

Tech specs

  • DVCPRO = 25Mbit/s 4:1:1
  • DVCPRO50 = 50Mbit/s 4:2:2
  • DVCPRO100 = 100Mbit/s 4:2:2

P2Edit

Recording of DVCpro, DVCpro50 or DVCproHD onto PCMCIA-sized solid state memory cards.

P2 to hard diskEdit

CamerasEdit

  • Panasonic AJ-HDC27 - DVCproHD, variable frame rate

BetacamEdit

MPEG2/IMXEdit

HDVEdit

Tech specs

  • Chroma subsampling = 4:2:0
  • Bitrate = 25 megabits per second

the 'prosumer' high definition format, recording high definition video onto miniDV tape using MPEG2 compression

HDCAMEdit

Tech specs

  • Chroma subsampling = 3:1:1
  • Resolution recorded to tape = 1440 x 1080

Cameras

  • Sony HDW-F900, 1920x1080 sensors
  • Sony HDW-750P
  • Sony HDW-730s

UncompressedEdit

  • Post production is often done uncompressed
  • It's now becomming possible to capture uncompressed, too

Preface: data versus videoEdit

Formats like 2k and 4k are considered "data" rather than "video". A scanner which produce 2k files from film negative are called "data scanners" as apposed to "telecines". Why? The main difference between "data" and "video" is that "data" doesn't use any chroma subsampling and is always RGB (as apposed to a video colour space like YUV). I.E. data is always 4:4:4 RGB.

Advantages of using uncompressedEdit

  • No compression artifacts
  • Maintain full latitude (useful if the footage will be graded)
  • Very little processing required

Disadvantages of using uncompressedEdit

  • Requires lots of storage
  • Requires very fast hard disk

Uncompressed formatsEdit

  • HD <= 1920x1080
  • 2k = 2048x1556
  • 4k =
  • 6k =
  • 8k =
