The headache issues with Sony Vegas dealing MP4 files may causes by hardware issue or codec issue. First make sure your computer is powerful enough and has enough disk space as Sony Vegas requires your computer be powerful enough and have enough disk space for video editing. That’s to say, if your source files are quite large and you won’t have enough space on the output folder, Sony Vegas will not import MP4 files.

If your computer is powerful enough and you have enough space on your hard drive, but still have problem of loading MP4 video to Sony Vegas, the issues can be caused by the unsupported audio and video codecs packed in the MP4 container. you’d better transcode MP4 to a format editing-friendly format, such a Vegas’ MPEG-2. Here is a workaround for you: https://format-compatible.blogspot.com/2014/10/how-to-use-mp4-files-in-sony-vegas-pro.html

I had the same problem.
The only think I had to do is to install Quicktime 7 and my problem is solved.
Better look on forums before posting because there are already many treats like this in the internet.

Actually, Sony Movie Studio supports MP4, but it only prefers MPEG-4 codec instead of others. However, MP4 as a container format can include various video codecs. So if your MP4 files are not accepted by Sony Movie Studio, it’s probably because of the video codec incompatibility. To get rid of the trouble, you need to transfer MP4 files to Sony Movie Studio preferred codec and then import to Sony Movie Studio for editing.
