Sony Vegas error: "An error occurred while opening one or more files. An error occurred while opening a codec"

Hi!
I'm not English, so probably there will be a lot of grammatical errors: I'm sorry for this!
Anyway, everytime I try to open an .AVI file with Sony Vegas Pro 11 (64 bit) it says (how you can se from the title):
"An error occurred while opening one or more files.
An error occurred while opening a codec"

This appen opening my camera's videos. It's strange, because some time ago Sony Vegas could open that type of files!

I try to find the exact codec of this videos and GSpot says that are "Motion JPEG" videos.
What can I do to fix this problem?
Thanks!

Have you installed any codec packs like K-Lite? These can really mess up Vegas Pro and other NLE's.

[Antonio Varriale] "In the "installed-programs" list I found "MyFreeCodec" and I uninstalled it, but I had the same problem."

This could still be the cause. Many codec packs don't uninstall correctly and leave your PC in an unusable state for video editing. This may have happened to yours. You should never install a codec pack on a video editing PC.

[Antonio Varriale] "So, now.. What should I do? "

I don't know of any way to recover from a codec pack problem other than to format and do a clean install and never install a codec pack again. I know that's extremely drastic so I would only do it as a last resort.

[Antonio Varriale] "I think it's strange that Vegas has problems with "Motion JPEG" files: a lot of people on Youtube have the same problem, but with Xvid/DviX .avi."

Well... Vegas (or any video editor for that matter) is depending on the codecs installed on your PC to decode the video files. When the codecs get messed up, it's not Vegas' fault. Try re-installing Vegas to see if it can re-establish it's own codecs again.

Install Quicktime Movie Player and K-Lite Mega Codec Pack
Restart PC,open up Vegas and see if it works this time.

Or else

Download freemake video converter
Convert to .MP4 OR to .WMV and try reimporting those files into Vegas
MP4 and WMV works like a charm in Vegas

Thanks for the tip :D
Never faced any issues like that lol

[Glenn Cowan] "What about the Avid DNxHD codecs? "

Avid DNxHD is a great intermediary codec.

[Glenn Cowan] "I successfully was encoding to the 175 setting...that is until this morning, now I get the dreaded "An error occurred while converting with a codec.""

While you are getting the same error as the title of this thread... this thread turned out to be primarily about AVI codec paks and the problems they could cause. Since AVI codec paks don't affect MOV files, this is probably not your problem.

I would start a new thread and explain exactly what you have been doing that no longer works.
