You can change the settings of your video recording to get the best possible quality for your computer. Click the Video tab on the main Bandicam window, and then click the "Settings" button in the "Format" section. By default, this is set to "Full Size". This means that the final video will be the same resolution as the original recording. If you are recording a full screen program, the resolution will be the same as that program. If you are recording a window, the resolution will be the size of the window. If you want, you can change the resolution to a set size. This is useful if you are going to be putting the video on a device that only supports specific resolutions, but may result in stretching and skewing if the resolution is a different ratio than the original recording. The FPS of your video is the number of frames that are recorded each second. By default, this is set to 30, which is the maximum FPS currently allowed on YouTube. If you want a higher quality recording, you can increase the FPS. Higher FPS will result in larger files and will put more strain on your system while recording. You may notice significant performance issues if your computer is not powerful enough to record at a high FPS. The codec is the software that processes the video while it is recording. By default, this will be set to Xvid, as this is supported by most systems and devices. You can choose a different codec if your video card supports it. If you have a high-end Nvidia card, you can choose the "H.264 (NVENC)" for the best recording quality. Lower end Nvidia cards can choose the "H.264 (CUDA)" option, AMD users can choose "H.264 (AMP APP)", and if you are using Intel integrated graphics, you can choose "H.264 (Intel Quick Sync)". If you have multiple video card options (Nvidia and Intel, for example), choose the option that uses your active video card. If your monitor is connected to your motherboard, you will most likely want to choose the Intel codec. If your monitor is connected to an Nvidia or AMD card, choose the codec that matches your card. The "Quality" drop-down menu allows you to set the general video quality of your recording. These are represented by numbers, with a higher number meaning a higher quality. A higher quality video will mean a larger file, but if you set the quality too low you will lose a lot of clarity and detail.
summary: Open the Video Format settings menu. Choose your resolution. Set your frames-per-second (FPS). Choose your codec. Set the video quality.
