- Container: Encapsulates all elements of a video, including audio, video content, and metadata.
- Codec: Responsible for compressing video and audio; affects both file size and quality with separate codecs for each.
- Frame Rate: Measured in frames per second (fps); a higher frame rate yields smoother motion in videos.
- Frame Size: Individual frame dimensions in pixels; directly connected to video resolution and aspect ratio.
- Resolution: Indicated by numbers like 1080p or 4K; reflects the video's image quality through varying horizontal lines and pixels.
- Aspect Ratio: Ratio of width to height in a video; common formats include 4:3, 16:9, and 21:9.
- Bitrate: Measure of video quality; a higher bitrate correlates with superior video fidelity.
