Video bitrate refers to the amount of data processed per second of video playback. A higher bitrate results in better video quality but requires more bandwidth. It’s especially crucial when streaming high-definition content or gaming online. If your connection speed is limited, you may need to lower the bitrate to prevent buffering.

GOP Size

GOP (Group of Pictures) is a term used in video compression. The GOP size determines the frequency of keyframes in the video stream. A shorter GOP size can improve video quality, especially during fast-moving scenes, but it may increase file size. A longer GOP size is used to reduce file size without a noticeable impact on quality.

Force Key Frames

In video encoding, keyframes serve as reference points for subsequent frames. Forcing keyframes ensures that the video quality is maintained even if there’s significant movement in the video. For live streaming or fast-moving content, forcing keyframes can help reduce visual artifacts.

Frame Width & Frame Height

These settings control the dimensions of the video frame. Adjusting frame width and frame height impacts the overall video quality and aspect ratio. For example, you may want to adjust the frame width to match the native resolution of your TV (e.g., 1920 for Full HD or 3840 for 4K).

Slices

Slices are segments of video frames that can be independently decoded. In encoding, slices can help distribute processing power across multiple cores, improving performance and reducing latency during video playback. This setting is especially important for streaming videos or encoding large files.
