30fps to 29.99…
i have a lot video products that i have been selling via one particular website, and they have always asked for 30fps. and now i have found another site on which i am selling my vids and they want 29.97fps. does it matter which way i do this? i am definitely not an expert in the nuances of video, so i could use some help (and maybe my little scenarios below will seem somewhat naive or absurd to true professionals):
i thought of three ways to do this (i’m sure there are more):
1) just render out from my 30fps timeline by changing to 29.97 in export settings.
2) take my 30fps sequence and import it into a 29.97 sequence and render out as 29.97 (not sure this would make any difference or not) 😮
3) render out as 30fps (using a lossless codec like qt animation) and then import back into premiere and render out as 29.97 (i thought this might work more smoothly since all transitions and effects would be already rendered and perhaps that would make for a smoother transfer from 30 to 29.97)
btw: my projects include both 30fps and 29.97fps media. and i just thought of this: would you suggest going into “interpret footage” and changing all video to 30fps for a 30fps project and change to 29.97 for a 29.97 project? maybe this is an unimportant or silly thought as well…
well, thanks for your time.

If you shot with any sort of video camera…the footage is already 29.97. The only way to have 30 fps straight up is if you rendered it out of something like After Effects or other video creation software. Or if you shot with a DSLR that doesn’t shoot 29.97 (early Canon 5D, most point and shoot cameras).
But if you shot with a video camera, ANY video camera, and you shot 30fps…it’s 29.97. Because that’s the default video signal for NTSC.

i don’t do a lot of shooting. most of my stuff is created in AE (motion graphics, etc) or is 3d animation – and both, up to this point, have been 30fps progressive).
if i do shoot something, it’s with an old canon HV30 (which shoots 30fps progressive). and i work with a lot of stock footage, and some of it is 30 and some is 29.97. all my actual projects (in premiere and AE) are set up as 30 fps, not 29.97.

Just select 29.97 when you render out a master for them, it’ll be fine.

the HV30 is an HDV camera. HDV is 29.97.

not sure how to do the quote thing here…
Dave quoted me, and then responded:
“[Lon Waitman] “most of my stuff is created in AE (motion graphics, etc) or is 3d animation – and both”Then it’s pretty easy to work in 29.97, yes?
My main question was not how to go from here, but to work with old project files that were already 30fps.
And I guess I really don’t understand my camera. It has three settings for shooting — regular HDV, 30fps progressive HDV and 24 fps progressive. Aren’t those last two different than 29.97? (and i have mainly shot with the setting at 30fps progressive)

btw, thanks chris tompkins and dave laronde, that it will be ok to just render out at 29.97.

Correct. those three settings are 1080i 29.97 interlaced, 29.97psf (basically progressive) and 23.976psf (again, basically progressive.)
They write it as 30fps and 24fps because that makes more sense to consumers and it’s shorter. Very, Very few cameras that say 30fps actually shoot 30fps… most really shoot 29.97. Shane Ross listed the few exceptions: The Canon 5D Mk2 with it’s original firmware, and most point and shoot cameras.
All real video cameras shoot fractional frame rates. (in the US anyway)
