I see the video frame rates for EOS DSLRs listed with "(29.97)" after "30" and "(59.94)" after "60". I do know all about what those frequencies mean. But I also know that the North American digital video standards recognize BOTH the whole number rate AND the 1000/1001 rate, now. My question is, is the lower 1000/1001 rate listed because it is available option, or is it the only rate provided?
And what about the 24p rate ... is it really 23.976 Hz?
I'm looking over choices for a new DSLR. If one has BOTH video frame rates and the other does not, then that will be a big favor for the one with both.
And another question. There are some systems which have 24p as a capture frame rate, but up convert it to 30p the same way a 24 fps film would be upconverted to legacy NTSC TV broadcasts. Although such conversion is no longer needed since ATSC supports both 24p and 23.976p, and video to file encoding formats all support true 24p encoding, there are some products that make silly assumptions. If a DSLR video feature can encode 24p as 30p, as an option, that's fine. But recording it literally the frame rate it is shooting at is highly preferred (and it's video out on HDMI should likewise be as is if the rate conversion isn't enabled).
