FFmbc is a fork of FFmpeg that is "customized for broadcast and professional usage".

480x360 frame containing letter-box 16:9 square-pixel video to IMX30 MXF

After using ffmpeg to transcode to IMX30 video and audio it is possible to use writeavidmxf to create media directly usable in Avid MediaComposer 3.0 and above.

IMX30 (720x608i25) video + 4 PCM audio tracks in an MXF file to h.264 video + 2 AAC audio tracks in an MP4 file
