The quality of the recorded video depends on the video quality of the source file, computer configuration, computer performance and the recording size of the recording area you select. For a better quality recording, we suggest you use a computer with a dual-core CPU and 2 GB of RAM or above. Also please check the following:
1. Make sure the source video is of good quality.
2. Close any other unnecessary programs to make sure the computer is not being over tasked, and if you wish to record an online video make sure that the Internet connection is running smoothly, you can also wait for your web browser to buffer the online video before starting to record it.
3. Ensure there are no other sounds when you play the video.
4. When the red frame appears, drag it to set the recording area larger before clicking the REC button to start recording.
