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

Uncompressed

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

Preface: data versus video
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 uncompressed

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

Disadvantages of using uncompressed

 * Requires lots of storage
 * Requires very fast hard disk

Uncompressed formats

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