I'm pretty confused about AVCHD and why it causes so many computers so much trouble. How is it that my Canon camcorder can play back AVCHD video so beautifully on the TV, yet there is really no simple option I can find that will allow for the equally beautiful playback of such video once it's been offloaded from the camera. Is there some super-hampster in that camcorder? Is it a eight core monster able to decompress and play AVCHD without breaking a sweat while my quad-core CPU and 1 gig video card crumple like prepubescent girls doing chin-ups?
I just don't get it. At this point, while I love my camcorder, I seem to think the technology is either way ahead of the curve for simple playback or HD video is still in that infancy where nobody can agree on a format and thus we have nothing but confusion and half-assed answers.
Can anybody share in my frustration or lead me to the promised land? |

My AVCHD video plays fine, I'm running a dual core machine with a 512 MB video card. It's obviously the Canon's fault.

I don't think I've had any problem with mine on a Mac using iMovie or Final Cut Pro. I have 8 cores (which I don't think will make a difference) and just a 512mb card. I do think that it might convert it to the Apple Intermediate Codec on import though and I then edit and output from that video.
At least I think that is what happens... |

I had a lot of issues getting it to work with my linux box ( I know, those linux fanboys again ), but found that for just playing the MTS files VLC ( for winders too ) seems to do a wonderful job. Now if you want to edit, thats a different story altogether.

I have a similar problem with the AVCHD files from my Sony camcorder, which produces mts files. VideoLAN(updated to version 1.0) player also plays it very choppy. Just shows a few stills, just drops a ton of frames. The latest PowerDVD(HD version). I tried the trial, plays them better than any player I've tried thus far. Watchable but could be better. Updated a bunch of codecs, still no luck. I guess I don't have the correct one installed? I have 256mb video card and 1.5gb of system memory.
Doc, try the CoreAVC decoder trial and see if that helps. It won't let me download the trial again, but it's worth a shot just to see if it plays the files.

But what I don't get is why the little camcorder is so proficient at it while a computer can't keep up and chokes? I'm guessing the actual crunching power of the camcorder isn't awesome.
I've been using Adobe Premiere Elements 7 and while it does ok, it does leave a lot to be desired. First playing back on a computer has trouble because the screen natively wants to display in progressive and I seem to get a lot of interlace artifact. But even figuring out how to export files and in what format to be played on what device on the TV is very difficult and I would think well beyond the typical consumer. I'm surprised the cameras have a following unless I just stumbled across a for-geeks-only piece of equipment.
I've heard the Windows Media Player in Windows 7 is supposed to be able to play native AVCHD video which will be helpful. Hopefully it does a good job of it. I'm hoping the playback technology catches up with the format instead of it becoming obsolete.
Techo, do you know what benefit CoreAVC would have over PSE7?

The little camcorder has a h.264 hardware decoder specifically for this task, as do many of the newer gfx cards as well but the consumer ones are way behind the commercial cards that shops use to edit film. I think those also have hardware encoders. If you bought a ATI or NVidia video card after 2007 you shouldn't have a problem. As they should both decode HD video files without leaving any work for the CPU, so I read.
CoreAVC I read is more efficient software decoder so it's worth a try. Just to see if it makes a difference. It will also install a codec which will make Windows Media Player play the file if it can't already. But the codec is also a trial. pffft. I'll be trying it on another pc over the next few days.
ETA:
Searching for more info. Every few months I try to see if anything new has come out. Run into this forum today //www.hv20.com/forumdisplay.php?f=19 seems like a wealth of knowledge there. And an oldie of an article but those same problems still exist //news.cnet.com/8301-17938_105-9746777-1.html
In that last link a poster suggested MediaCoder. Downloading that now. Have a feeling my PC just doesn't have the proper codec installed or there's a bunch of old ones hanging around that get in the way.

| This works fine if you use pinnacle studio 12, I have been using that for all my video production and dont have any issue. Also the AVCHD video format is nothing bu blue-ray V1, so if you have blue ray burner, just dump the directory structure from your Canon camcorder, burn it and play it in any blue-ray player and you should not have any issue. |
