Sony and Panasonic jointly developed AVCHD and announced it in 2006, aiming to bring the efficiency of the then-new H.264\/MPEG-4 AVC codec to consumer and prosumer high-definition camcorders, which until then had relied on tape-based formats like HDV. Both companies shipped the first AVCHD camcorders in spring 2007, recording to memory cards, hard drives, or recordable discs instead of tape.<\/p>
The format’s defining choice was wrapping H.264 video and Dolby AC-3 audio inside an MPEG-2 transport stream, a broadcast-derived container, constrained by a specific set of camcorder profiles for resolution and bitrate and organized in a defined BDMV-style folder structure so AVCHD discs would play on Blu-ray-compatible hardware. That heritage is why raw AVCHD footage \u2014 the .mts files inside a camcorder’s PRIVATE\/AVCHD folder \u2014 behaves differently from a simple video file: metadata about chapters and clip continuity lives in companion index files, not the video stream alone.<\/p>
For a DAM ingesting footage from consumer or prosumer camcorders \u2014 corporate video, event coverage, older marketing archives \u2014 AVCHD is a recurring source format, and the practical pitfall is losing the folder structure during a naive file copy, which breaks chapter and continuity metadata. Because AVCHD uses long-GOP compression optimized for recording efficiency rather than editing, DAM-driven workflows typically transcode it to an intra-frame mezzanine codec for active editing while keeping the original AVCHD card structure intact as the camera-original archive.<\/p>","protected":false},"excerpt":{"rendered":"
