WikiPedia articles:
BetamaxEdit
VHSEdit
sVHSEdit
Hi8Edit
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.

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
HDCAM SREdit
Tech specs
- Chroma subsampling = 4:4:4
D1Edit
D5 HDEdit
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 =
