Frage von ennui:
Many cameras with HD video function, DSLR or mini-camcorder, have indicated in their specifications, a frame rate of 30p, partly as the only possible frame rate. Are these "true" 30p? Or 29.97 rounded off as in SD NTSC, only to slip number? Or maybe so-so, depending on the model?
Antwort von tommyb:
It all depends on the devices.
As DV camcorders record the work with 29.970 - because it provides the standard.
The cameras can rotate synonymous videos, almost always make exactly 30p (such as the 5D MKII).
Ie no default = no compulsion 29.970

Are these "true" 30p? Or 29.97, as in SD NTSC You have, of course, in
both cases, 30 frames per second.
The different time bases apply only to the "census" of the images in relation to real time, ie on the time code that is used and synonymous only in NTSC / ATSC procedures.
It distinguishes between drop-frame timecode and non-drop frame timecode.
In both cases, the material has a speed of 29.97 frames per second.
All 300 seconds only, then begin exactly as s.Anfang Picture of a second.
The drop-frame timecode, and omits to take account of the 30p every 300 seconds, a picture
in the census. The understanding is important that it happens only in the count. The actual images in the film, of course, remain available!
The non-drop frame timecode can be made and no picture is ever to 30p, so some actual elapsed time and time code diverge.
So it is of relevance only in so far for you, if you are working with time code. However, 30 (real) images have you ever.

And cameras that need no processing time code, such niceties have not.
But it just does not change the fact that in both cases you have 30 images.
