field problems after effects 3d images

[Matt Waryga]

Hey,
Unless you exported the 3d animation as lower field first I would not interpret as separate fields. In AE I would keep the interpretation of each item how you originally exported that source either from Maya or final cut. Since you are exporting it back to final cut, and it seems it likes to have LFF footage, I would make sure to render the composition with fields. This option is found in the Render Queue tab under render settings, Time Sampling, then Field Render.

Hope this is of some help.

hey matt, thanks for taking the time to answer, ive tried doing what you said and im actually starting to think its not about fields…

the thing is when i do it like that it loads in final cut with the shift fields filter on +1 and the fields are really wrong i change it none and it looks like it did before…

it might be a frame rate thing, when i export from maya it doesnt say anywhere nothing about frame rate im using the CCIR PAL Quantel PAL, does anybody know if it uses 24 or 25 frames?

in after effects it interprets it as 25 ,actually im going to play with that and see if tumble upon the problem…

thanks! Regards Dave

Hey Dave thank you for answering, sorry maybe i didnt explain myself, i do go from maya to AE with the TIFF sequence, what i export from FC is the video footage im going to integrate the 3d in, but as i just said to matt im starting to think its not a field problem…maybe a frame rate problem or just shity animation from my part.

and i havent actually read the help section for that( i know i should have )but i will read it right know thanks for the link 😉

Hey Dave thanks for the fast reply,thats actually something i dont look at very much: Frame rates, as i usually only do 3d stills and the footage i get is always DV never cineon ( i wish it was cineon).

I actualy didnt know the first wit, its interesting, but as i live in Spain i always deal with PAL 25 frames and thought maybe maya was exporting 24 frames with the CCIR Quantel PAL ( as it doesnt say anything in maya about the frame rate , or probably i havent found the place )

Anyways its a pleasure to read the “to wits” i will keep in mind to check the frame rate first , thanks again

go 59.94fps from Maya then each field gets a frame or use Revision’s fieldskit Re-interlacer which adds fields motion estimated, something AE can’t do alone. It works great on animated buttons too.

[Chris Wright]

that was NTSC 29.97fps 59.94 fields/sec. PAL is 25fps or 50 fields/sec. So for PAL TV, Maya out 50fps as fields off, so when its dropped into PAL comp, the frames will get turned into fields automatically, yay!

Now if for some reason, you are unable to render out of Maya, for any reason, like time just use this.

Hey Chris! thanks for taking the time to answer ,this is a very good suggestion…im rendering from maya right now with PAl 50 field frame rate preset.

Thanks for the Link its very interesting ( reading it know ).

ill post back when the render is over!

Thanks again best regards Dave

Yiiiiija! problem solved!Chris you are the man of the week for me!!

i rendered out of maya with the PAL 50 field preset and then in AE in the interpret menu i told AE that was 50 frame per second, rendered that out as a quiktime with PNG compression with alpha and voila smoth and sexy animation on a external monitor.

id like to thank matt cue,Dave LaRonde and Chris Wright for there advice!
