![]() Everything else is completely automated – nice job Axel! Then edit the install script as noted in the README to grab the newest version of ldecod. Sudo apt-get install mplayer ffmpeg x264 faad2 faac a52dec mencoder faad libfaad2-0 libfaad2-dev subversion csh ![]() Installation is very simple, all it requires in Ubuntu is a quick apt-get install: M2tstoavi is the best information I have found (so far!) to uncompress the AVCHD video files on my camcorder and convert them into a. It literally contains everything we need to transcode the video into formats of our choosing that are usable in non-linear video editing programs such as Avidemux or Cinelerra. On a side note, my Google-Fu is really spot on lately. The first thing I searched for was “AVCHD Linux” and found a post over at AVS Forum. Let’s get down to the meaty bits, shall we? I wouldn’t be surprised if it was the typical Sony software suite that is about as useless as the media it is distributed on. I’ve never actually installed the software that came with the Sony Handycam, so I’m not sure what I’m missing out on, but it doesn’t seem like all that much, to be honest. It would certainly be faster to playback the videos in real-time and capture them using the component outputs from the camera… but that wouldn’t be a challenge. This would be a familiar process to anyone who has used a digital camera and imports pictures to their computer. Copying files from the camera to the computer is a simple drag n’ drop affair. When plugging in the Sony HDR-SR5, it functions as a USB Mass Storage Device. Using the method detailed here, it takes about 5-6 minutes to uncompress and transcode a minute of video, on an Intel Core2Duo running at 3.2GHz with 4GB of RAM and a 10,000RPM hard drive – OUCH! It takes some rather respectable computing horsepower to actually convert the files into an uncompressed format that can be played with in a video editing software package. The compression is where a majority of the AVCHD format complaints come originate from, since there is not much out there in terms of being able to edit video stored in the format without uncompressing it first. I’ve seen it mentioned that a Standard Definition compressed clip of is actually larger in file size than an HD clip in AVCHD format. ![]() The files the camera generates are compressed at an incredible 15:1 ratio. Even in Windows (or OSX for that matter) many people have headaches with the AVCHD format, so I figure that Linux users are probably going to be having a helluva time trying to get it to work. I’ve read a few things about the format the camera uses, called AVCHD. The best example is on YouTube, where it happens behind the scenes in the Google computing cloud, and everything “just works.” The answer was a tiny bit more complicated than I imagined, and immersed me into the otherwise unknown world of video transcoding, which is something millions of people do every day but probably never think about it. When I opened it, the first question in my head was not atypical of a Linux users’ train of thought: This holiday season, I was an extremely lucky recipient of a Sony HDR-SR5 video camera with a whopping 40GB hard drive inside. ![]()
