I am using Kdenlive 16.04 and need to render in mxf format. But cannot find option for mxf.
Will appreciate help with this.

You would need to create a custom render profile specifying the mxf extension.

Example: 10-bit DNxHD (185Mbps) 1080/25p + PCM audio:



Bear in mind though that MLT/FFMPEG creates mxf files in the OP-1a format, which is fine for most applications, the exception being Avid Media Composer which requires mxf files in OP-Atom format. If that is a requirement you would need to look at secondary tools for converting your render e.g.

What video (H264, DNxHD, ProRes etc) and audio format (PCM, AAC etc) do you want to render out to and at what resolution/frame rate ?
