The maximum file size that the AVI file format allows is about 2GB. My Screen Recorder Pro employs segmentation to work around this limitation. Whenever the recording file size in AVI exceeds ~1.9 GB, a new file (segment) is automatically created. This segment will again have a maximum size of ~1.9 GB, and if the recording continues beyond the segment size, further segmentation is carried out.
You can also specify the maximum recording file size. If the recording exceeds the size you specify, segmentation will be carried out to allow the recording to proceed uninterrupted.
