videóformátum

A videóformátum, or video format, refers to the way digital video data is organized, stored, and presented. It encompasses the file container, the video codec used for compression, and the audio codec for sound. Different video formats are designed for various purposes, including streaming, broadcasting, recording, and editing.

The file container, such as MP4, MKV, or AVI, acts as a wrapper that holds the video and audio streams, along with metadata like subtitles and chapter information. The video codec, such as H.264 (AVC) or H.265 (HEVC), determines how the video frames are compressed and decompressed. Efficient codecs reduce file size while maintaining acceptable visual quality. Similarly, audio codecs like AAC or MP3 compress the audio data.

The choice of video format impacts file size, playback compatibility, and streaming efficiency. For instance, MP4 with H.264 encoding is widely used for web streaming due to its good balance of quality and compression. Professional video editing often utilizes less compressed formats to preserve maximum detail during post-production. Understanding video formats is crucial for users to select the appropriate settings for their needs, ensuring smooth playback and efficient storage.
