I just installed AE CC 2014 and I found it in there, but it's not present anywhere in AE CC 2015. Why is this? It's quite an annoying setback. Is there any way to get the MXF OP1a codecs into AE CC 2015?
It used to be in AE 2015 until a recent update and now it's missing.
Maybe it has something to do with this: After Effects CC 2015 MXF OP1a XDCAMHD 50 PAL (4:2:2)
Looks like Adobe removed it rather than fix it.
The MXF OP1a format has been removed from the After Effects render queue. To export to MXF OP1a, use Adobe Media Encoder.
