rendering out to 16×9 PAL anamorphic with AE file?
Hi everyone,
I need to ask this question straight out as I have too many times now rendered out for compositing in after effects, in what I have thought was the right aspect ratio etc, and then realising that it doesn’t really lock in correct… i really thought I had this process boiled down, but i don’t so here we go…
I’m trying to get to 720×576 PAL anamophic, i,e. 16:9 with rectangular pixels at aspect ratio 1.42. This is the format I want to composit in.
Thus, in C4D I render out with following numbers in the fields in the Output tab in Advanced Renderer:
Resolution: 720 – 576
Film Format: 720 – 576 (it seems logic to me to change this to a 16×9 format, but if I do above numbers change too)
Pixel 1.42 – 1What happens now is that my render comes out fine, but my accompanying AfterEffects file that I save out doesn’ match up 100%. However, if I later, after rendering, change my resolution to 1024 – 576 (which equals proper PAL 16×9) and save out a new AE file (not render) I get a composition with square pixels which my previous rendered movie fits and onto which the new AE exported camera also locks onto perfectly.
I’m sorry for the long post. This is just as confusing to me as it seems…
While I am getting this to work with this roundabout way of doing it, I am sure there is a more intelligent way of solving this and setting it all up…
Any advice would be super appreciated.. after all that’s why I’m writing this 🙂
Cheers,

Wow, that is potentially confusing. All I can bring to the tale is my personal experience with this type of problem and quite simply said, I don’t really get it either… but, I have noticed that the AE comp that the c4d/.aec file generates has always been square pixels. I’m not certain why the render file and the ae file don’t match, maybe Maxon thinks its doing you a favor by making a square comp, if you’ve ever tried to arrange planes in ae in a non square format, it can be quite frustrating. So, maybe check the comp settings of the .aec generated comp and see if simply changing the pixel ratio fixes you up. Please let us know your results.

Bear,
Thanks for your reply! It’s good to know that i’m not alone out there. The thing is that I’m much more versed in AE than C4D. I usually work in non-square pixel comps in AE due to the anamorphic 16×9 standard, so I get that part of the problem.
It’s like you say though. The AE (.aec) comp out of C4D always turnd out in square pixels, even if one sets the pixel dimensions specifically to 1.42:1 .. unfortunately it doesn’t work to just changing the pixel dimentions in AE from square to rectangular (not for me anyway) without messing up the camera match from C4D…
so back to where I started I have to correct the frame size in C4D (for the AE export only, that is) to 1024×576 to get a square pixel comp in that format instead which then matches up in AE with my 720×576 anamorphic C4D render…sorry, feel like i’m just repeating myself, though hoping that something will come out of the mist… please bluntly point out if i’m being thick and missing something obvious here… i think that pondering over this might have somewhat numbed my brain… cheers /d
