Hd 24p At 23.98

[ericw]

Hi all,

I will be working on a project that will be edited in HD720p24 (23.976p). Do I need to somehow set the framerate within maya to this value? Will I be able to playback the rendered images at the correct speed using fcheck, framecycler or quicktime? What other issues would be important in setting up my pipeline?

Thanks in advance

Eric

unless you sync audio you dont need to.

This is a typical misconception jsut like dpi. see poepe dont acthat computers have no clue of realworld mappings, cerualy work recognize all that well certtainly times the easiest for the computer but....

Maya makes frames, just like it only makes pixels. DESPITE the fact that 90% of people seem to think on the contrary.

And yes the computer can conform teh speed to whatever despite the setting agan all move files are just FRAMES. infact i doubt that the computer can actuay playback the frames even that accurately (theers allwsy slight fluctuation in the actua gained framerate it just fixes it by waiting a bit more elsewhere) so there will be shift anyway.

Yes, we do need to sync audio and lip sync too it after it had been cut at 23.98 fps. I know it seems that it is a trivial difference, but since we will be doing on the order of 450 minutes of animation, it may be critical

Can I actually set the fps in maya to 23.976? How do you do that? Anyone have experience with this? We are cutting on FCP as well.

Thanks,

Eric

Well you probably wont do it all in one go in any case since having 450 minutes of animation in one file is unwieldy at best. But more likely impossible to load (it also takes approximately 1.5 man years to produce at minimum). so you could fix the difference in each shot even then your time would lag half second across the film so if you fix the difference in say 10 shots the allocated lag would be about 0.05 seconds (roughly one frame) over the course of each shot, now since 450 minutes is long time

1) you cant really expect people to watch it in one go at minimum youd need it in 3 parts, even then having a movie with one shot for each part is going to be booring into the utmost. so in all actuality it wouldn't realy accumulate at all.

2) So in all actuality you'd have at most 10 minute shots during which time the sync would go off by a hundredth of a second or 1/4 frame! This mans you probably animate bigger offset than that.

3) the sound crew is not going to be happy to do the entire movie in one go, neither is the guy doing the cutting because theres not going to be anuything to cut together.

but yes you can set the value for maya playback. Just do playbackOptions -playbackSpeed 23.976;

In the end no difference but feel free to be pedantic More than that your computer cabt sustain this rate perfectly (the computer will wary the framerate more than the difference of one promille) so during editing, playback, etc you wouldn't notice any difference so you couldn't relay sync more accurately either.
