Importing 3840×2880 footage
Hi all,
Looking for help on an issue I don’t understand.
My workflow is to sequence JPGs in After Effects at 24fps, export to Quicktime ProRes files, then edit in FCPX. Lately, I’ve been exporting these JPG sequences at a custom 3840×2880 resolution instead of 3840×2160, because that way I can get more of the original 4:3 image without cropping – I can then make choices in FCPX, if I want to shift the 16:9 frame around.
However, when I import my footage into the FCPX 4K timeline, I have to enlarge the clips to 134% in order to cover the full 16:9 frame without any pill-boxing. At first I assumed this was some weird glitch — the original clips are recognized as 3840×2880 in the info tab — but now I am starting to see some artifacting on certain images that make me think FCPX is indeed enlarging the clips bigger than 100%.
Can anyone tell me why I have to make the clips 134% instead of <100%? The only answer I can think of is that FCPX is recognizing my custom resolution as anamorphic for some reason, and squishing it back to 2160px height. Never had this issue when I used the same workflow in FCP7.
Thanks

Select all the clips and change the spatial conform to “none” in the inspector.

Jeremy is dead-on right: FCPX is assuming you want that footage to fill the frame it expects, so when you scale on top of the scaling it’s already done, your artifacting results. I’ve had this happen to me with 4k footage and now I don’t take that setting for granted.

Thanks very much for the response!
However, I just tried this and now my footage is stretched from 4:3 to 16:9, and, at 100%, covers the 4K (3840×2160) frame area. I can only guess that the program is interpreting it as anamorphic somehow? at 100% it should be larger than the frame..
Unfortunately I am still unclear on how to fix this without re-rendering out the footage at the standard resolution…

Thanks very much for this response! Works perfectly!

Ugh I sent that first message too soon — was accidentally looking at the one 16:9 clip in my timeline. Now I can’t figure out how to delete a post on this board. Apologies and thanks again.

You chose “none” and not “fill”?
Spatial conform of none should put your photos at 100%scale and crop the top and bottom.
If you are seeing anamorphic then put your clips in a timeline first before viewing. Make sure your timeline is set to 4k 16:9. (3840×2160)
