What is the difference between a container and a codec?

A container (like MKV or MP4) is a wrapper that holds video, audio, and subtitles. A codec (like H.264 or VP9) is the actual algorithm used to compress and decompress the video data within that wrapper.

Is MKV better than MP4?

Neither is inherently 'better' in quality, but they have different features. MKV supports more advanced features like multiple subtitle tracks and attachments, while MP4 has much broader hardware and web compatibility.

Why would I use 10-bit encoding for 8-bit content?

Using 10-bit encoding for 8-bit sources often improves compression efficiency and significantly reduces 'banding' artifacts in gradients, even though the source lacks the extra color depth.

What does BT.709 mean in video settings?

BT.709 is the industry standard color matrix for high-definition (HD) video. It defines how digital values are converted into the colors you see on a screen to ensure consistency across devices.
