Convert Multi-audio Channels MXF with Original Audio Tracks Preserved

How to keep multiple audio channels when converting MXF to MP4/MKV/MOV format with lossless quality? This guide provides a simple way to convert multi-track MXF to MKV/MP4/MOV file for playback and editing.


Found on multi-track MXF forum, there are following issues you may have encountered:

“I have some MXF files from a normal Canon XF100 and want to convert them to any format that FCP adopts. The key point is I don’t want to lose any of the audio channels that I recorded with two microphones. Is that any workflow for this?”

“I have downloaded some MXF files from the P2 Card, recorded using a Panasonic AG-HVX201AE Camera. I want to extract a small P2 MXF clip to play with QuickTime Player, is there any way to keep all my audio tracks?”

“I have some XDCAM files recorded from Sony PMW-200, when I put them onto pinnacle studios, they don’t lag. When I upload them to moviemaker however, the videos are very laggy and freezy. Is there any way to fix this? My clips have different mics on the left and right channels, so I want both audios (channels) to play at the same time.”

From above, you can see many folks are asking how to get your editing programs and media players to work with multiple audio channels MXF files. I also have this problem but most the converting program cannot do this; they either loss one of my audio track or duplicate one of them and cover to another channel. So, to playback or edit multi audio channels MXF videos on Mac, the best way is converting MXF to program or device supported formats retaining multi audio channels. Here, Pavtube iMixMXF would be a quick answer to the questions mentioned above. You can choose to either mix the multiple audio tracks/channels into one track or repack them with all the audio channels preserved.

    I find this works in that the audio comes out correctly, but the video has trails and blips – any ideas?
