I'm not having any success getting Re-Master to even recognize the m2ts files in the Open dialog - they are greyed out. Having read a few older posts it seems like Re-Master has this capability, however it seems to be not working on my Mac computer.

I have successfully extracted Sony MVC files into separate L/R files with the M2TS extension and want to mux them but haven't yet seen a way to do this in Re-Master if it doesn't recognize the native files.

Suggestions?

I think you can use ClipWrap to rewrap your m2ts file into mov file first。Then Remaster should handle it。
But you can check this http://techblog.cineform.com/?p=3426.It can handle MTS,I do not konw about M2TS.

Ivan, in the AVCHD wrapper it's my understanding that there is no difference between MTS and M2TS data streams except the name. I've tried to rename the M2TS files to MTS so as to try and mux them as if they were generated by a Panasonic 3DA1 but consistently get a ReMaster error message about not recognizing the file structure. As for the M2TS files, ReMaster shows them as greyed out files so won't access them.

Frankly it's very disappointing that Cineform hasn't addressed this yet, the MVC format isn't going away any time soon and many people in the future will be looking for a simple way to process these 3D files in Neo3D software.

Thanks for your suggestions, still looking for solutions though.

Really? No one has an answer for this??? Pretty unbelievable.
