Having Trouble playing AVI. files in quick time

You could open the video in QuickTime Player, go to the Window menu, Show Movie Info and look in the Format: field to see what type of video codec you might need.

And then look here:

great link, but still can't play an AVI file.
installed Xvid and AC3 and still get nothing.

Any suggestions?

In the show movie info window it says
Format XVID, 720 x 480, Millions,

Another file I can't view reads
Format: DX50, 572 x 312, Unknown

Running Quicktime 7.0.4 Pro
Installed Codecs:
3ivx D4 4.5.1 for OSX
Flip4Mac WMV Import.component
AC3 Codec.component
DivX 6 Encoder.component
DivX 6 Decoder.component
XviD_Codec v0.5.1.component
Flip4Mac WMV Export.component
AppleIntermediateCodec.component

Dan I won't go into all I've gone through to find this solution or explain the details other than you must convert avi to DivX. There is a small application available for free download at http://www.feringa.net/downloads/avi2DivX.jar

When you say that you can't play the file do you mean that it won't open, or that there is no video, or no audio or some combination?

DX50 is DivX 5 by the way. The DivX 6 component will play DivX 5 video. It appears that it will also handle xvid (even without the xvid delegate component.)

Thanks for the link, I downloaded the jar file and it failed to convert.

Info section says "FourCC codec used in this AVI file is not SEDG"

Any more suggestions, I really appreciate the response.

I get neither audio nor video. I get a white screen and the Quicktime is missing components... message.

Ummm...
DivX 6 for Mac for Intel - Beta 1

Apparently I forgot to add that to the big list at the link I gave you. Its in there now though. 🙂

I installed the xvid component as needed after getting only a black screen that plays (but no audio).
Then after rebooting I then got only video (mute off and volume was turned up) but no audio.
Am I missing another codec?
Have Quicktime 7.0.4 with XviD and also Divx video 5.0 components installed.

Pismo G3 400 Firewire Mac OS X (10.3.9)

Go back into QuickTime Player, Window menu, Show Movie Info and check the Format: field again - it should list the audio format as well. Perhaps its AC3 ?

AC3 CoDec - 0.4b1 for AC3 audio in AVI files - FREE - this one claims compatibility with QuickTime 7.0.2 and later
http://www.mactcp.org.nz/quicktime/AC3CodecMacOSX.sitx
AC3 CoDec - 0.3 - FREE - NOTE: NOT CURRENTLY COMPATIBLE WITH QUICKTIME 7.0.2+ ! (If your AVI's have no sound, remove this CoDec)
http://www.insaneness.com/

A52 decompressor for A52/AC-3 audio (although not in avi divx files apparently) - FREE
http://shep.thefridgeowl.com/a52codec.php

No audio format listed at all in that location only XviD.

I downloaded the jar file too and it failed the conversion with the same error message.

Hmmm, do you have or would you download MPlayer OSX or VLC to see if either will verify that there is no audio in the file?

MPlayer OS X - Plays just about everything has built-in decompression for other formats such as Indeo Video 3 - FREE

-- If QuickTime Player won't even open a file, try running MPlayer and showing the playlist window, drag the file into the playlist and click the "i"nfo button to see the file format, video and audio compression types.

VLC (VideoLAN Client, application, not a QuickTime Component) - FREE
