"Hello, I have some DNxHD files with a .mxf extension on them which I would like to bring into After Effects. I've never done this before. I also notice that the audio left and right are separate channels. But I don't even care about the audio, I just want to bring in the video. How would you do this?
Thanks for your help!"

According to the above description quoted from the current forum. We can clearly find that he seems to get a bit confused when importing Avid DNxHD MXF footage into After Effects for further editing. Indeed, in general, After Effects does support mxf import or export, but has strict requirements only limited to P2 and XDCAM, and obviously DNxHD codec is excluded.

As someone suggested, in order to get your DNxHD .mxf media imported into After Effects smoothly, you'd better export the MXF files from your Avid as a Quicktime basic codec using the "Same as Source" option. In AE, you can render directly to DNxHD in a Quicktime container for fast-import back into Avid. However, this way will be a bit time-consuming and somewhat complicated. Fortunately, after multiple testing we've figured out, in order to get around all these issues for good, the best solution is to transcode DNxHD. mxf to MPEG-2, the optimal video format when working with all Adobe products.
