I have movies that I want to view and edit in iMovie, but it and QuickTime does not recognize one of the two codecs associated with the files. The codecs are MPEG-2 and AC3. IMovie '08/'09/'11 cannot access non-system or non-video editor added codecs. Muxed MPEG2/AC3 content must be imported directly from the camcorder into iMovie '08/'09/'11 as iMovie has its own special cancorder import routines built into the app which turns the MPEG-2 video into all I-frame MPEG-2 video and the AC3 audio is converted to Linear PCM (AIFF) content, both of which can be edited in iMovie. In addition, start and/or end time offsets are added to minimize variations in A/V synchronizarion.
Content that cannot be imported directly from a camcorder or simulate import as if it were directly from a camcorder must be manually converted to edit compatible compression formats.

Hi Folks I'm not sure where this post belongs as it appears to be several issues, so I'm posting to audio as this is the latest. I'm not an expert but I've been video audio editing editing with several programs for a couple years. I'm running 64 bit Vista I was using 32bit and VDub mod without problems for about a year. Then it suddenly stopped working. I was unable to load and play all avi files. I was getting the error message: 'Couldn't locate decompressor for format DIV3 (Microsoft High-Speed MPEG4 V3 Hack: DivX Low-Motion) requires a Video for Windows (VFW) compatible codec to decompress video.
DirectSHow codecs, such as those used by, are not suitable' After doing some forum searching, and trial and error, I switched to for 64 bit and downloaded and installed vdub 64 bit. I had success with avi files encoded with all types of vidoe codecs (so far), but with avi files that were encoded with AC3 audio, I got the error message: 'No audio decompressor could be found to decompress the source aduio format. (source format tag: 2000)' I first went into settings for audio decoder (x64) to see if AC3 was enabled. It was enabled with liba52. I tried switching to libavcodec but no success.
After more searching on this forum, I downloaded the (build 1.63b) and the Decoder (build 1.6). I installed the AC3filter without hitch, but when I went to install the AC3ACM Decoder, I kept getting the error message: 'Setup can not copy the file AC3ACM.acm 'Ensure that the specified location below is correct.' I made sure I was installing the x86 x64 bit version. Tried and retried, manually pointing the installer to the specified path. Strange thing is now the problematic AC3 avi files will load into Vdub 64.

I have tried again to install the AC3ACM Decoder without success. Yesterday when I was trying to resolve the video issue I had the same problem installing the Divx3 codec. A similar error message popped up saying: 'An error occurred while copying file Divxc32.ax Cannot copy file to destination directory' I'm wondering what's up.
Are the two failed installation issues indicative of another underlying problem that I'm not figuring out? I feel like I'm heading down the road of redundancy, installing more codecs than I need. Shouldn't having AC3 enabled in Klite have been enough for VDub to work? Maybe I just don't understand the issue. Can anyone advise me on this or point me to a directory explanation that will clear this up? With thanks for all the help I've received here so far.
Great forum with great advice.
How To Install Ac3 Codec
Sometimes when you try to play a video file in a player like Windows Media Player, you might receive an error that the file cannot be played, or a codec is not installed on your system. In fact, a number of audio and video playback issues can often be caused by not having the correct codec installed on your computer, or even the wrong version installed.

If you’re wondering what a codec is, it’s most commonly made up from the 2 words Coder- Decoder, and is simply a device or a small piece of software that can encode or decode a piece of data, in our case audio or video data. If for example you download a movie clip from the internet, your media player has to have access to the same decoder that it was encoded in. Sometimes if you were to ask a less experienced person if they have, most users would not be able to tell you easily.
Finding this information can be quite difficult for an average home user, but there are ways to get it, some easy and some a little more difficult. Here we’ll provide the manual way of finding your installed codecs through Windows, and also some automatic ways through 3rd party software to help determine what video and audio codecs are installed.
Find Your Codecs with Sherlock A program to give you some useful information about your computer’s installed codecs is Sherlock – The Codec Detective! Everything is listed in the single window and you can easily see information about the codec, it’s associated driver file, version, date and description. Sherlock is a tiny portable executable file of around 80K meaning no installation is required. When you run The Codec Detective it will first scan for installed codecs and list in a window any that appear to have problems.
When you get to the main interface these “broken” codecs will be displayed in red. You can easily switch between audio and video codecs by selecting from the drop down in the top left of the window.

There is also an option to export the data about all the installed codecs to a text file which is handy if information about what’s installed needs to be sent to somebody to troubleshoot or determine if the correct files are installed. The program has been tested and works on Windows XP to Windows 7. Using Nirsoft InstalledCodec Nir Sofer of Nirsoft is known for producing simple and effective little utilities, and InstalledCodec is yet another one that does exactly what it’s designed to do. In addition to the audio and video codecs present on the system, it can also display the DirectShow filters, and a valuable function for users of a 64-bit Windows is the ability to display the relevant 64-bit codecs and filters. Any missing or problem codecs will show in pink in the main window.
Each entry has a lot of information displayed on its line including names, descriptions, locations, sizes and also the merit of the codec, which is the priority at which each codec is given over other compatible codecs for a particular format. Another useful option, although not something the novice should play around with unless guided by someone more experienced is the ability to enable or disable anything in the list, ideal for troubleshooting problem codecs.
InstalledCodec is a portable program and works on Windows 2000 to Windows 7. Codec Information Through Windows One way of checking is through any version of Windows Media Player although the button link is in rather a hidden away location. Open windows Media Player and if you don’t have a toolbar menu visible right click towards the top of the program to bring up the context menu. Go to Help - About Windows Media Player, then click on the Technical Support Information link at the bottom.
This will open a webpage that lists several bits of information including installed audio and video codecs. There is also the MSInof32 built in Windows utility which can display codec information, but it doesn’t display all those installed and only seems to list pretty much the defaults installed by Microsoft. Windows XP users also have a rather basic option to display the names of installed codecs by going to Control Panel - Sounds and Audio Devices - Hardware tab.
Now click on either Video or Audio codecs in the window and click the Properties button. Click on the Properties tab to be presented with a list of the desired codecs. Double clicking an audio codec will give you a few options such as changing its priority and disabling it altogether.
By Many media codecs are included in Windows Vista, but as technology changes daily, it is important to know how to install new codecs for the Windows Media Player. Codecs are important in the Windows Media Player world because you need a codec to translate different kinds of media files into data that WMP can understand. A codec (short for coder-decoder or compressor-decompressor) is a small program that converts data from one form to another. Unfortunately, filename extensions don’t tell the whole codec story.
For example, WMA files can have a WMA 7, WMA 9.2 or WMA 10 format. It’s up to Windows Media Player (or Winamp, which also plays WMA files) to look inside the file and decide which format was used to create the file. After the determination has been made, WMP (or Winamp) hauls in the right codec to decipher the file. You don’t need to lift a finger. Sometimes, though, Windows Media Player doesn’t have the correct codec on hand to play a particular file. For example, AVI is a popular file format that can be created using a particular kind of video-encoding technique called DivX. Although DivX files are gaining in popularity, Windows Media Player still doesn’t include its codec.
So, in order to play a file using this format, you need to install a new codec.
