AVCHD and Me


Oooh.  Is that a new Sony camera you’ve got there?  Impressive.  Does it really shoot in full HD?

It does?  Wow, can you show me some video you’ve shot with your new camera?

No?  Why not?

The problem with Sony’s full HD movies is that they are recorded in AVCHD.  Picasa, iPhoto, and Lightroom all fail to import these files directly.  Most of us use one of these apps to import our pictures from our camera to our computer (and delete them from the card after importing).  When this fails, what else can we do?

If I put the camera card into the Mac, I can import the movies into an iMovie event.  This import is done by iMovie copying the AVCHD from an MTS to a MOV container. The GPS and other EXIF data appears to be lost in this process, however.  There is an iMovie Events folder from which movies can then be extracted for use elsewhere.  The beauty of this approach is that I don’t have to burrow down through the folder structure on my camera card to find the pictures.

Similarly, Windows Live Movie Maker on Windows 7 can edit AVCHD files.  But on my pre-Windows 7 PC, I have to manually copy the MTS files from the Streams folder; use Sony’s bundled PMB app, or expensive video editing software like Pinnacle, Sony Vegas, Corel VideoStudio X3, or Adobe Premiere. Sony’s PMB (PC only) is the only way I’ve found to retain EXIF data.  It can be used to upload pictures for sharing, but I haven’t tried uploading videos to YouTube or Vimeo.  Sites which retain and display EXIF like Flickr and Picasa won’t get video GPS info from PMB.

I haven’t found a way for Mac users to retain GPS data on AVCHD videos.  The 1080i MP4 movies only import via iPhoto or Lightroom (I don’t have Aperture to test with that), not Picasa.  iPhoto does not retain the coordinates for 1080i videos.  Both AVCHD and MP4 can be 1080, but AVCHD is 1920×1080/60i and MP4 is 1440×1080/30p (on my Sony HX5V at least).   Lightroom and iPhoto import both 1920×1080/30p and 1280×720/30p MP4s, but do not import geographic coordinate metadata.  Picasa doesn’t even see those files on my camera card.

In short, most movie formats are easily handled at one stop by the same app that handles our pictures.  AVCHD requires video specific importing and manual deleting.  So if the AVCHD format is so problematic, why does Sony use it?  I suppose the primary reason is that AVCHD video provides full HD, but doesn’t gobble up a huge amount of space on a camera card.  The AVCHD format is also Blu-Ray compatible.  If the AVCHD folder is moved from the camera card to a DVD, BD-R, or other media compatible with a given Blu-Ray player, that player can play the movie.  If all one wants is the video clips, they are buried in the Streams folder with an MTS extension.  They play well on both the Mac and PC using the VLC Media Player (free).

The iPad camera connection kit can only import video recorded in MP4 or MOV containing a limited subset of video and audio codecs.  Since I don’t travel with a computer, only my iPad, when on the road, I generally set my camera to record in MP4. As a bonus, I can edit my movies using the well-worth-it ReelDirector app.  (Sorry, even the 720p MP4 files are incompatible with iMovie on the iPad.)  Note that 1080 MP4’s also will not play on the iPad but they can be copied from your camera card for later transfer to a computer when you get home.  This limitation is a shame because my travel videos are really important to me.

When I’m shooting locally, I do shoot in AVCHD.  This requires that I import the videos using iMovie and delete the videos directly on the camera.  (iMovie copies the videos into events instead of moving/deleting them.)  One can upload from iMovie to most online social sites (except Picasaweb).  If one includes the iMovie Events folder in Picasa, I can upload to Picasaweb using that app.

The Canon EOS Rebel records in 1920×1080/60i in MOV but does not offer GPS.  The above hassle could be avoided by the use of a Canon and an Eye-Fi card with a-GPS enabled.

In conclusion,

1) If you have Windows 7, import your AVCHD video into Windows Live Movie Maker and delete the videos from the card using your camera’s delete function.  (Or just import it with your pictures in Windows Live Photo Gallery.)

2) If you own a Mac, import using iMovie and delete the videos from the camera card using your camera’s delete function.

3) If you own a pre- Windows 7 PC, buy Corel VideoStudio and delete the videos from the card using your camera’s delete function.

4) If you can’t be bothered, avoid Sony and Panasonic and buy a camera that records in a more flexible format (like a Canon Rebel).

5) If you say “edit-schmedit”, copy the contents of the AVCHD folder onto a DVD-R or SDHC card and stick it in your Blu-Ray player.

I’ve noticed that there are a lot of people on forums frustrated by this format.  Hope this can be of help to those who wish to enjoy the highest level of performance from their camera with the least amount of hassle.

    I don’t know what version of Picasa you’re using, but I’ve been using it to import AVCHD and mp4 video from my Alpha 55 since buying it a few months ago without issue [except for the sticky one of it not erasing AVCHD video from the camera during import, which no import software I’ve seen does – the camera itself has to manage that as part of its BD-compatible playback database].
    Come to think of it, I was also importing AVCHD from my workplace’s Canon HD camera last year [unintentionally, even – using import all without paying attention].
    So .. Not sure why your experience is different, but it works fine here [on 5 computers with the most recent version of Picasa].

    Excellent. I’ll check my version numbers on Picasa and retest. At this point I’ve moved to Lightroom and use picasaweb plug-in. (Google+ has pushed me in the Picasaweb direction.)

    Your computer’s abilities to handle different video formats isn’t just a matter of the program you use. Any program you use (eg, Picasa) will make use of the audio-video coder-decoders (“codec”) that you have installed in order to read and write a particular audio/video file format. Think of a codec that tells a program how to handle a new A/V format as an extension of the operating system – like a driver for a printer, which is available for any program that wants to print things, it’s a video-file-format-understander available for any program that wants to use video files.

    Mostly you won’t notice the existence of codecs because your operating system will supply a bunch of codecs when it is first installed, and when you install programs they sometimes install their own codecs too – which other programs running on your computer can then use. Since you don’t suddenly start using a really new video format very often, it usually all just works.

    My point is that upgrading to a new version of Picasa might or might not be what you need to do: you may need to download a better codec instead (or as well). The K-Lite codec package (which has lots of codecs) comes highly recommended, though I can’t say I’ve used it myself.

    Good luck,

    Sean

      I want to test that out. Even with the latest version of Picasa I’m not seeing the AVCHD files in my import dialog.

    And how about this?

    If you use Sony’s own PlayMemories Home software to import files from a one of their HDR-CX115E units, you have to manually remove the .MTS files from the card after importing the data.
