Method 1: Install Codec to Solve Sony Vegas Pro AVI issues

To fix this, one way often used is to install the codec on your computer while another way is to transcode AVI to Sony Vegas Pro supported AVI video with compatible codec or some other Vegas Pro compatible format video. Normally, if your SonyVegas Pro refused to work with AVI video, the major reason will be the codec issue. Sony Vegas Pro won't handle all AVI files. If you know that AVI is just a video container, then it will be easier to understand this kind of issue.ĪVI can work with video codecs like MPEG-1, MPEG-2, MPEG-4 (A) SP, H.264/MPEG-4 AVC, VC-1/WMV, RealVideo/Theora, Microsoft MPEG-4 V2, VP8, and audio codecs including MP3, WMA, RealAudio, AAC, AC-3, DTS, PCM, LPCM.

You must be confused that why Sony Vegas Pro can't accept your AVI files when AVI is in its supported list. Have you meet the issue that when you tried to import a AVI file into Sony Vega Pro, it kept rejecting it? Or Sony Vegas Pro just randomly decided not to work with your AVI videos for like no reason.
