I am planning on buying an AVCHD camcorder in the beginning of the next year, so I would like to make sure I can edit it on Linux. So far I haven't been able to play mts (source files from such camcorders) files with VLC (the feature is already requested) and I would like to edit the footage of course. Is there any information, when, if, Kdenlive (or it's depending packages) will get the support for this codec? |

We can support it when ffmpeg does. Can you play the file with ffplay? |

it start playing, but the picture is unrecogniseable. this might be due to the fact that my current computer it's as powerfull (it can play 1080i files, but AVCHD is supposed to be much more CPU intensive) I've also searched on the ffmpeg.org website, but couldn't find AVCHD mentioned anywhere, but there is support for AVC (HD just meand High Definition aka big resolution). Maybe someone can test files like these and see if they work for them: |

No, ffmpeg does not support AVCHD yet, so nor does kdenlive. But I have a new camcorder that produced AVCHD so I have been motivated to look into it. I would say that there is at least a 'fair' chance that kdenlive will work with AVCHD by early next year, but that isn't a promise. |

I can only recommand to look at the HV20.com forum. |

Canon is releasing HG10 in october, which is essentially the same optics as HV20 and with an HDD and it records to AVCHD. I'm planning on buying HG10 if I can get proof of satisfying performace filming sports (fast moving objects). |

I read on Camcorderinfo that AVCHD was giving poor results: http://www.camcorderinfo.com/content/Ca ... Format.htm Quote:
A camcorder’s compression method has a huge impact on video quality. This becomes particularly clear with the HG10. The HV20 (Review, Specs, Recent News, $903), released early this year, uses HDV compression, which is older but has a much higher quality, particularly in regard to how it renders motion. AVCHD tends to show compression artifacts – blocky, pixilated groupings of image aberrations. Quote:
There are further constraints. Software engineers were tearing their hair out for awhile trying to create efficient ways to deal with the tightly woven algorithms. Working with AVCHD is taxing on your computer, and you’re going to need a powerhouse processor and memory to do it with any expediency. They also write that 24P mode does give good results. We need to wait for HG10 release, to be able to download footage. |

HG10 24p AVCHD raw footage is available here: Quote:
this one should be on the lowest setting: AVCHD is h264 .... |

I am almost sure that ffmpeg supports h264 full frames, not interlaced format. The reason is that ffmpeg guys believe that interlaced format has no future. In 24p mode, there "should" be no problem (except bugs!). |

Obviously, this is not 24p raw footage Quote:
ffmpeg -i 00011.MTS test.avi The raw files are interlaced, thus not working in ffmpeg. My personal choise is to buy an HV20, work in mpeg2 during a year, resell it and buy the next-next generation of camcorder working in AVCHD (full frames) on Flash cards. If you would like to be sure about AVCHD support on ffmpeg, contact ffmpeg-user directly. |

You may ask 24p footage to this person: http://dvinfo.net/conf/showthread.php?t=101059 Kind regards, |

I'm not interested in 24p, I wnt as many frames as possible. AVCHD is indeed a very new thing in camcorders, but it probably will get more popular with the rise of popularity of HDD and memory card camcorders - this is the main reason for me: ditching tapes. At the moment I tape over my tapes a lot and it's going to ruin my camcorder completely (i have the cheapest one, ha!), so on my expensive camcorder I don't want this to be an issue. On Watch-impress there is a mpeg video of HG10 performance and I didn't see any artifacts, except whe filming a water stream...but I probably should check it out on a Full HD TV, just be sure... If all else fails, I can stil consider GZD-H7 (i hope it's called that) from JVC, which can shoot mpeg2 I think... |
