Does it have one of those nicey numbers? If it's a 50XX :: XX, it would point to the audio stream being compressed and because of the failure, compressed in a format/ CoDec AE does not know or cannot handle. I'm afraid in that case you will have to convert or extract your audio externally. I suggest you use GSpot or similar tools to view the full info on the AVI. then go looking for tools that can handle your file.
Mylenium, thanks for responding;
my particular .avi does not have the 50XX :: XX that you mentioned in either the error message or the .avi filename;
after your post I attempted to use Adobe Media Encoder to re-do the .avi, but Media Encoder did not like it either;
however, windows media player plays it successfully;
I should mention the error message in full:
"After Effects warning: Audio conforming failed for the following file: my_file 8000_1.cfa. Perhaps due to disk space."
for some reason the error mentions .cfa instead of .avi ... hmmmm, interesting;
Oh yes, CFA is the actual conform file. I recommend you check your media cache settings in the AE prefs. Simply purge it. It defaults to your user home directory (My Documents\Adobe) and on many systems this can get very full. These conform files are not cleaned out automatically, since AE keeps them around in case you use the same items later again, so you should make it a regular routine to purge the cache, when you are done with a project after a few weeks. Or you assign it to anotehr directory on another drive that has more space so you can keep it indefinitely.
I'll check it tomorrow and update the post;
thanks for you time;
Mylenium, unfortunately clearing the cache did not solve it;
1 - Edit --> Purge --> All
2 - Edit --> Preferences --> Media & Disk Cache --> Conformed Media Cache --> Clean Database & Cache
3 - deleted Database folder & Cache folder ( as defined by Edit --> Preferences --> Media & Disk Cache --> Conformed Media Cache )
but still the problem exists;
if I come up with anything I will post it here;
Mmh, then perhaps the stream is really damaged? Can you open the file in anotehr program with the audio intact? It may be worth a try to e.g. load it into VirtualDub and save the audio and video as two new separate files.
so, my .avi is coming from a digital camera, manufacturer: Praktica;
the .avi does not seem to work in any of my adobe products: AE, premier, media encoder;
well, I downloaded virtualdub, and imported my .avi into it, and simply chose File/SaveAsAVI, which gave me a new .avi which is effectively a copy of the original;
I imported the copy.avi into AE and it seems to work fine;
I am not a video person, so it is really not practical for me to attempt to discover the reasons why Praktica's .avi's are not working in AE, etc; so I will settle on the videodub workflow;
thanks for your time,
Ran into this problem today
Google pointed me to this thread. Do you happen to have Premiere running at the same time?
I was having the same issue with .r3d RED footage on Mac AE CS5. But as soon as I quit Premiere, After Effects stopped giving me that message. (Even though Premiere had no footage loaded. And yes, all my disks had gobs of free space)
no I asn't using premiere then; I concluded that it was related to the digital camera's built-in .avi exporter, which is what I used for the ae file.
I had the same problem ... and i just covert the video format to WMV ... and its work as i want ^-^
I had the same issue today and I found a solution!
You need to change the name of the clip or audio file and reconnect the media. That will refresh the indexing on premiere and will let you conform the file as a new file.
Hope this help to solve the issue.
