How can I separate a video into two parts?

Nero Vision closes when trying to add a video?

• I'm trying to burn a Video DVD of a concert that is in two parts. I added the first part to the list, but every time I add the second part, Nero just closes. No crash message, no warning, it just closes, and it's only THAT video that does it. How can I fix this? As far as I can tell the video is NO different from the first video, so I don't see why this is happening. They're both MP4 and as I said before, the first one adds just fine. Thanks in advance.

• Answer:

  Low end specs computer, not enough resources for video processing will be the most likely cause for that. Video processing, encoding and editing requires high end processor and graphics card to run smooth. List your computer specs here and I can tell you for sure what needs to be upgraded to improve your video editing performance. Also lack of proper video codecs can cause a shutdown in your Nero Vision. Best video editing programs are Sony Vegas and Pinnacle Studio.
