When I play a file with a .avi extension on my computer, the associated viewer it opens in is Windows Media Player. When this happens, I get the sound but not the video. Hence, I want to download some type of viewer that will best work with an avi file.
You don’t need a new viewer, you need new codecs. Find and download the Nimo codec pack, and you can use Windows Media Player to view your files. There are a lot of settings to play with, but the default ones seem to work OK.
BTW, a file type (AVI) does not tell you which codec you need. You may be able to run some AVI files and not others. If it is a codec you are missing Windows Media Player 6 will tell you it is attempting to download it.
To see what codecs are installed go to Control Panel - Multimedia - Devices and there you can see the audio and video codecs
FWIW, I recommend not installing various MPEG4 (AVI) codecs to view different video files. Installing a variety of codecs can cause system instability issues.
Rather, I suggest installing ffdshow. It’s a universal MPEG4 directshow playback filter that will work with MS Media Player, Zoom Player and any other directshow compatible video player. Also, it contains a host of post-processing options (denoising, deblocking, etc.) that can radically improve the picture quality of your videos.
Depending on where you get it from, the Nimo codec pack has a history of carrying a virus or just screwing up your system in general. It almost single-handedly wiped out my laptop a month back… and it wouldn’t even let me play a DVD until I uninstalled it completely.
The DivX bundle is said to install spyware software, though AdAware never popped up anything on my system, but it is far more stable and reliable.
Frankly, the codec mixup is a HUGE mess. Microsoft refuses to touch DivX encoding in particular and MPEG4 in general for the same reason they don’t like MP3 - their own formats, WMV and WMA. Of course, the majority of computer users don’t even know what a AVI is, they just click on things and expect them to work.
For the record, ffdshow is an excellent program. I got a fairly decent boost in image quality from it. It’s also fairly well-behaved. No serious crashes in the several months I’ve been using it.
I really like Crystal Player. It’s small, optimized for performance, buffers frames while paused, and automatically and continuously synchronizes audio and video at each keyframe.
