Premiere 2017 V.1.2 Crashing when exporting to MXF OP1a with a .MOV as a source

Hello all,

We are having an issue when exporting to MXF OP1a with the source file being a .MOV file. Premiere (and media Encoder) Hang up and a memory leak begins eventually crashing the used program.

This does not happen with all .MOV files here is the media info of a file that it does occur on.

While on with adobe support I was told this must no longer be a supported format...

We have found a work around which involves transcoding the .MOV files to MXF outside of adobe and then using those however, this is very inefficient as we have tens of thousands of items in our library. We have used this workflow on previous versions of premiere and will roll back to 2015 if we must however we would like to avoid that. I suspect this has something to do with Adobe now using their own quicktime decoders and is likely a bug.

Any thoughts or suggestions however to make this work in 2017 without the workaround of having to transcode the files outside of premiere would be greatly appreciated.
