It depends on where they came from. AVIs can be made up of any of thousands of codecs. AVIs produced by third-party software programs often use proprietary codecs that are very difficult to work with.
What model of camcorder is your AVI coming from and what resolution is it? How did you get it from the camcorder to your computer?
Welcome to the forum.
Unfortunately, the AVI format can have almost anything within it. It's like saying "I have a car, and it won't run." The first quetion would be, "what kind of car is it?" It could be a Ferrari, or a Chevy Volt. Lots of differences.
For more background, and for tips on finding out what is in the AVI, see this FAQ Entry: http://forums.adobe.com/thread/440037?tstart=0
If you can let us know what is inside the AVI "wrapper," someone can give you tips on how best to handle that material.
Hi Bill, Thanks for your reply, I have followed your link and now understand a little the problem. I think I will stop here and forget about the avi and not bother.
Thanks again Bill
Hi Steve, Thanks for your reply to my post, I have decided it is not worth the trouble to fix it. I just asumed the software was up to the job.
Thanks Again Steve
What did you find in that AVI "wrapper?" Did you run one through MediaInfo, or G-Spot?
My first guess would be DivX, or its open source cousin, Xvid.
However, we've seen some other CODEC's, that are not traditional to AVI, inside.
