My dad has a Sony HXR-NX5E which writes its output to SDHC cards in AVCHD format.

Wanting to back up his video and not understanding the AVCHD structure, I originally got him to copy the contents of the PRIVATE/BDMV/STREAM/ folder to his backup storage, seeing as they were the video files and they were playable in VideoLan Client. My dad filmed multiple separate events onto the same SDHC card and I thought that by separating the *.MTS files for a each event into a separate folder, we'd be able to separate the events and work with them later.

I now know that we ought to have backed up the entire BDMV folder and in order for him to edit the video and transfer it to Blu-ray or DVD, it's easiest for him if we could recreate a AVCHD structure for the video files.

It seems to me that it ought to be straight-forward to recreate the clip files (*.CLI) for each of the *.MTS files and create a single playlist (*.MPL) file which will play each of the clips in sequence with no menus or anything else (and an INDEX.BDM and MOVIEOBJ.BDM file) without touching the MTS files at all. But after searching for and trying out a bunch of different free and trial programs, I can't seem to find anything which I can get to carry out this task.

I have problems with programs creating superfluous menus, insisting on re-encoding the MTS files and insisting on combing the video into one short file, presumably with all the streams overlapping.

Can anyone give me any advice on how I might achieve this?

To be clear, I would like an AVCHD which contains no menus, immediately begins playing the first clip and continues playing each clip in sequence until the last one, without re-encoding the video files.

When your dad got the camera did it come with software from Sony? Specifically does it have Sony's PMB (Picture Motion Browser)? If he lost it, go here: sony-mea.com/support/download/316131 Go here to learn how to use it: youtube.com/watch?v=k5tmwml4zeA –  filzilla May 17 '12 at 20:43
    
Thanks for that link. I didn't know of PMB. I've installed it now, but unfortunately, it doesn't appear to be able to directly import MTS files, so it won't work for my purpose. To be clear, I presume it can import MTS files as part of an AVCHD structure, but not without, like the files I have. –  Paddy O'Loughlin May 18 '12 at 22:56

Guess the original poster found his way to do it - I found the following that worked for me, even though I followed a different procedure. I didn't want to convert the MTS files before importing them to iMovie into anything else and was missing too the additional index / descripition files. this is the source and works for Sony SW / Cams. Potentially with other HW / SW constellation a similar way is possible. http://www.mac-forums.com/forums/movies-video/263323-how-import-mts-files-into-imovie-have-been-archived.html

So what I did: 1. I added the folder with my MTS files on my USB drive with the Sony PMB Picture Motion Browser - in fact I used the more recent Play Memories Home edition 2. Now I marked the MTS files from that source and exported them to an external USB drive - but you can use basically any medium (SDHC, maybe even DVD if you think that's better for archiving)

And now the new folders created can be either imported directly from the medium, copied to the Mac or other location from where you again can import them as archive in iMovie.

Good luck.

I use ffmpeg for that. Just plain concat filter with stream coping works.

ffmpeg -f concat -i ./file1.MTS ./file2.MTS -c copy output.avi
