Hi guys,
Ouch, yes, this is broken. Sorry about that; I’ve put the bug in the system. The workaround is to open your comp in AME and encode there.
A little background info: In CS6 we added two new classes of codecs to the MXF OP1a encoder, AVC-Intra and XDCAMEX. All of those codecs have this failure (AE applies an incorrect output constraint) except one, AVC-Intra Class50 1080 correctly constrains to 1440×1080@1.33. Under the hood we have to manually write the constraints for each format into AE, so it looks like we goofed this when those codecs were added.
So please use AME for encoding to MXF OP1a if you need to use AVC-Intra or XDCAMEX codecs. The other codecs (DV, IMX, XDCAMHD) use the correct constraints.
