Technically, there are no limitations.

However, please note that the longer your recording lasts, the more resources are required for persistent capture of the image with the constant quality. 

Also, if your recording is expected to be rather long, we suggest ensuring there is enough free space on your hard drive. 

If required, you can change the output folder or drive in the product menu Settings - Preferences- Files on Windows OS or MacOS.

We would also recommend using the internal drive as the output drive in order to avoid any sudden disconnect.
