About MTS to AVI Conversion
AVI (Audio Video Interleave), Microsoft's 1992 video container, uses an indexed frame structure that enables fast, frame-accurate seeking — a critical feature for video editing that the MPEG-2 Transport Stream format used by MTS/AVCHD lacks. Converting MTS to AVI moves camcorder footage into an editing-friendly container compatible with VirtualDub, older versions of Adobe Premiere, and Windows-based video production systems.
Why Convert MTS to AVI?
The MPEG-2 Transport Stream container used by AVCHD was designed for streaming and broadcast, not for frame-accurate editing. Its packet-based structure can cause timeline misalignment in editors that expect AVI's sequential frame index. Some NLE software (particularly older Windows-based systems) only accepts AVI input, and scientific video analysis tools often require AVI for frame-by-frame examination.
AVI also supports uncompressed and lossless intermediate codecs (HuffYUV, Lagarith, UTVideo) that are essential for multi-generation editing workflows. Converting MTS camcorder footage to a lossless AVI intermediate eliminates compression artifacts before grading, compositing, and effects processing.
