Does Client mix 24p & 30p?

[robfilms]

Client needs to create dvd to project at non-profit gala.

Client has talking head interview footage that was shot 24p/Standard Def.

He has another talking head interview tomorrow.

Should he shoot tomorrow's interview 30p/Standard Def and "correct" the previously shot 24p. Or shoot tomw's interview 24p matching previously shot footage and drop both 24p talking head interviews onto 30p timeline so a dvd can be made.

Does Client mix 24p & 30p?

Thoughts?

Thanks in advance

Be well

My number one philosophy and ethic in video production is never, EVER, mix frame rates.

By mixing in 30p, you'd enforce the rest of the 24p footage to be interlaced for compatibility with the 30p footage.

Thank you for sharing your thoughts.

Are you suggesting shooting the next interview at 24p/standard def (he used the DVX100b for the first talking head interview but didn't realize he set the camera to 24p)?

If so, will having 24p be a problem when creating a dvd for projection since a dvd spins at 30fps (29.97) not 24p

Again, thanks for sharing.

It does not matter which frame rate the DVX was set to use... it all goes to tape at 29.97. 24p footage has a pull-down added, and in order to edit that footage in 24p (23.976), the pull-down must be removed.

Now, are we talking about the regular 24p, or 24p Advanced? Both go to tape, as I said, at 29.97. If the pull-down is not removed, both can be edited in a 29.97 sequence. However, if it is to be edited at 29.97, 24p is more advisable than 24pA because of the 2:3:2:3 cadence. 24pA's 2:3:3:2 cadence was designed to be easier to remove for 24p editing, but makes it a bit more clumsy for editing at 29.97.

A DVD is perfectly capable of handling 24p material.

Oh I'm well aware of the cadence, hence me even mentioning that his using 30p in conjunction with 24p would force the 24fps footage to keep its cadence. It's a crime :crybaby:

It's great that you understand the cadence, but the explanation was for the benefit of the OP.

By the way, Cinema Tools can be used to convert your 30p footage to 24p.

I would never convert true 30p footage to 24p- looks like hell because progressive frames with motion in them have to be thrown away. Do a bit more research about this. 24p with 30p in a 29.97 timeline is not that big a deal as long as you leave the pulldown intact. Now this would preclude making a 24p native DVD and will not look as good say on a projector or a progressive display as it could have editing natively at 24p. But many folks would probably not notice the difference.
