While many have tried to standardize the naming of frame rates, many companies find ways to still confuse people.

When it is specified that a camera operates at "29.97i" or "30i", it means that it will have 29.97 interlaced frames per second.
When it is specified that a camera operates at "59.94i" or "60i", it means that it operates at 59.94 fields per second (or 29.97 full frames per second).

Notice that both of these definitions are exactly the same. Whether measured in frames or fields, you get the same number of full pictures per second.

**Exception. Some higher end cameras have the ability to operate at 59.94 full frames per second. However, this is most commonly noted as "59.94" or "59.94p".

Hope this helps.

It's as Devin says, in practice it's the same thing. (Though previously you were never capturing 59.94 frames/sec, rather 59.94 FIELDS/sec.)

The nomenclature has changed such that previously we spoke of no of frames for progressive systems, no of fields for interlaced systems - the standards bodies have now decreed that the nomenclature should ALWAYS refer to no of FRAMES, regardless of progressive or interlace. Unfortunately some manufacturers are much slower to adopt the new terminology than others, but what you're now seeing is manufacturers doing just that.
