One of the best, if not the best, video capture software available is MSI Afterburner. This software is a general GPU utility which includes overclocking options, GPU monitoring, and Screen/Video capture. However, as with most other video capture software, MSI Afterburner does have a few gropes. One of them is the fast that the software does not compress video which results in absurdly large file sizes. Another issue some have had is the MSI Afterburner not recording the amount of FPS that one is playing at(or lower quality recordings). Both of these problems have fairly simple solutions.
While MSI Afterburner itself does not compress videos, there are plenty of third party software options that do so. One credible and reputable option is HandBreak, which can be obtained through the following link to their download page: http://handbrake.fr/downloads.php. In order to utilize this software, one must first select the file which can be located, by default, in Users/Public/Public Videos/Captured or wherever one has designated the video output folder to be in MSI Afterburner’s settings. Then one needs to select a destination folder and file name. Also video quality, codec and fps can be set from the video tab and audio stream can be set from the audio tab. Usually, its is best to select the H.264 codec and a constant quality of around RF:20. Afterwards, a user must simply click the start button. For best encoding times it is recommended to not have many CPU intensive programs in the background as video compression/encoding software is remarkably CPU intensive.
Some users who have not gotten themselves acquainted with the Video Capture tab of the settings menu may find that the FPS and capture quality is not what they desire. To resolve this issue all that one needs to do click “setting at bottom right corner of the main software screen and proceed to select the Video Capture tab. There, a multitude or options are listing. For most uses, video format is best kept at MJPG compression while quality should be kept anywhere about 70% (the greater, the better). Frame size is a matter of personal preference but it is best to use full frame in order to record the entire frame (what is displayed at any given moment in game). FPS should be anywhere between 30 and 100 depending on what is recorded and what FPS one typically plays at.
