If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a 'runtime' error message. Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. Sony Movie Studio 13) could share the same file, saving valuable memory allocation, therefore making your computer run more efficiently.

These files were created so that multiple programs (eg. Dynamic Link Library files, like, are essentially a 'guide book' that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. is considered a type of Dynamic Link Library (DLL) file. ✻ Portions of file data provided by Exiftool (Phil Harvey) distributed under the Perl Artistic License.

Furthermore, a hard disk drive with a low transfer rate (on which Vegas Pro is installed) can also cause this problem.Copyright 2011 Sony Creative Software Inc. RAM and Hard Drive: We all are familiar with these Random Acess Memory or RAM is required by a computer to run different processes and Hard drive is required by a computer to store data.

Most people suffering from this problem have low-quality Graphics Processing Unit or GPU which do not have the graphical processing power to support Vegas Processing.

GPU Bandwidth: As previously explained, people keep upgrading their camera tech while ignoring their computer specifications.

This means that Vegas Pro has to do a lot of work to decode the video as it is playing back in real-time.

Video Codec: AVCHD H.264 video codec is used by the vast majority which specializes in saving video files after highly compressing them.

Thus, the same CPU now needs to work six times more when editing with Vegas, which causes the lag. Standard Definition video is up to six times smaller in file size compared to Full 1080p HD video.

Poor CPU Power: This problem genuinely started when people started to upgrade their Standard Definition Cameras to AVCHD Video Cameras but were still running their computers on Duo Core Central Processing Unit or CPU.
