Frequently Asked Questions
MTS and M2TS are file extensions often used for the raw AVCHD video streams. AVCHD is the overall format or standard, and MTS/M2TS are the typical file types you'll find containing the actual video data within an AVCHD camcorder's file structure.
While possible with some advanced software, AVCHD is generally not ideal for direct editing due to its compression. Converting to an intermediate codec (like ProRes or DNxHD) or a more common format like MP4 often results in a smoother editing experience.
AVCHD offers a good compromise between high-definition video quality and manageable file sizes, making it suitable for the storage limitations of memory cards in camcorders. It also leverages efficient compression standards like H.264.
Technical Details
AVCHD is a container format that typically uses the H.264 (MPEG-4 AVC) video codec and Dolby Digital (AC-3) or linear PCM audio. It's a proprietary format, often packaged within a specific directory structure including 'BDMV' and 'STREAM' folders. The actual video data is usually stored in .M2TS files within the STREAM folder.
