8-bit 4:2:0 video stores 256 shades per color channel and reduces color resolution by sampling color information (chroma) at one-quarter the rate of brightness (luma). This format is efficient for compression and streaming but offers limited flexibility for color correction and grading compared to higher bit-depth and chroma subsampling formats.

AVC (Advanced Video Coding), also known as H.264, is a widely used video compression standard that balances high video quality with efficient file sizes, making it ideal for streaming, broadcasting, and video storage. It achieves compression by reducing redundancy within the video data, which helps maintain quality while keeping file sizes manageable for various platforms and devices.

Long-GOP (Long Group of Pictures) is a video compression technique that reduces file size by storing only the changes between frames rather than every individual frame. It uses a combination of I-frames (intraframes with full image data), P-frames (predicted frames), and B-frames (bidirectional frames) to efficiently compress video over a sequence of frames. This structure allows for significantly smaller file sizes compared to All-Intra (All-I) compression, which encodes every frame independently. However, Long-GOP can be more processor-intensive to edit, since reconstructing any given frame may require decoding multiple surrounding frames.
