You can create multiple videos and combine them into a single file. This feature helps, when you are running short of time. You can create small files as time permits, and later merge them into a single file. The output file can be created in WMV, AVI, FLV, or MPEG4 formats.
To join your screen recordings, click Tools >> Join Files. You can right click the file and select Join Files, to add it in the File List.
Add the WMV and AVI files for joining with the Add button, or by dragging and dropping the files in the list.
To arrange the order in which you want the files to be joined, use the Move Up and Move Down buttons.
Selecting Output Format and Profile

Select the output file format from the Video Format drop down list. You can fine-tune the settings of the output file by selecting a profile that suits your need. When you select a profile from the Video Profile list, its details, such as the name of video and audio compressor, video bit rate and frame rate, and the audio format is displayed in the Details section. You can create your own custom profile by clicking the Custom button.
If you are joining your files to the WMV format you can provide additional information called Metadata like Title, Author, Copyright and Description by clicking on Metadata button.
Smaller dimensions means less load on the processor. Select the dimensions of the output file from the Dimensions drop down list. You can customize the height and the width. If the Lock this aspect ratio checkbox is selected, the height and the width is maintained proportionately.
