Sony claims that Vegas Pro 10/11/12/13 supports most commonly-used video codecs, including the MP4 (MPEG-4). However, problems like "Sony Vegas won't Open MP4 files" come up from time to time. For the users of camcorders like GoPro HD HERO4/HERO3/HERO2, Sony NEX-3, Sony Bloggie should be a familiar phrase. What's reason? If you are attempting to edit MP4 videos in Sony Vegas Pro, what's the available workaround?
In fact, the native import of some flavors of MP4 wasn't supported until Vegas 10. In addition, based on our testing, some MP4 files will import into Vegas Pro without QuickTime perfectly, whereas other MP4 files absolutely require QuickTime. The reason of the error mostly lays in the video format codec parameters. Not all MP4 files are supported by Vegas Pro, but some special .mp4, such as .mp4 (avc video codec, aac audio codec) videos. To make those unsupported MP4 files work well with Sony Vegas Pro, there are two methods:
Solution 1: Install the K Lite Codec Pack is a possible solution.
Note: We found people blaming the codec saying K-Lite is that it blindly installs all kinds of components (not just codecs), many of which are not compatible with each other. And it does not uninstall cleanly. If don't want to install a pile of codecs on your PC, try another approach.
Solution 3: Transcoding MP4 to Sony Vegas Pro more editable formats like MPEG-2 - it seems to be much easier and more effective.
To convert MP4 files to Sony Vegas friendly format, you can use EaseFab Video Converter Ultimate. It does a good job in converting .mp4 files to Sony Vegas Pro most compatible format like MPEG-2 with least quality loss. Plus, it supports encoding camera shootings in different formats (H.264 MOV, MTS/M2TS, XAVC, MXF, etc.) to video editing software compatible file types, i.e. MPEG-2 for Premiere Pro, DNxHD for Avid Media Composer, WMV for Windows Movie Maker, AVI to Pinnacle Studio to meet your different needs.
