• Answer:

  Camstudio is not stable. If you want to record for more than 3 hours, you should use Bandicam. It's free and decent recording software. * Key features of Bandicam - You can upload the recorded file to YouTube without converting. - The recoded file size is much smaller than other capture programs. - The maximum file size is unlimited as long as the local Hard Disk has free space available (Over 24 hours recording). - It has less lag than other capture programs (Bandicam uses much lower CPU/GPU usage). - Bandicam can record video at resolutions up to 2560×1600 in high quality (1080p full HD video can be made).
