Om konvertering från MTS till AVI

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.

Varför konvertera MTS till 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.

Vanliga användningsområden

Importing camcorder footage into VirtualDub for frame-level editing and filtering
Preparing AVCHD recordings for legacy Windows NLE systems requiring AVI input
Creating lossless AVI intermediates from camcorder footage for professional post-production
Loading camcorder video into scientific analysis software that mandates AVI format
Converting AVCHD to AVI for forensic video analysis with frame-accurate seeking

Så fungerar det

FFmpeg deinterlaces and transcodes: `-vf yadif -c:v libx264 -crf 18 -c:a pcm_s16le -f avi` for compressed AVI, or `-vf yadif -c:v huffyuv -c:a pcm_s16le` for lossless AVI intermediate. The AVI container does not support B-frames natively, so H.264 encoding should use `-bf 0` or Baseline profile if stream copying is attempted. Uncompressed PCM audio is standard for editing workflows.

Kvalitet & prestanda

Lossless AVI (HuffYUV/UTVideo) preserves every pixel from the deinterlaced MTS source, providing the maximum possible editing quality. H.264 at CRF 18 is visually lossless with a reasonable file size penalty. Uncompressed rawvideo in AVI is also possible but produces approximately 11 GB per minute at 1080p.

Tips för bästa resultat

1Use HuffYUV or UTVideo codec for lossless intermediates — they provide 2:1 compression with zero quality loss
2Always deinterlace MTS footage before encoding to AVI — interlaced content causes problems in most editing software
3Pair video with PCM audio (not compressed) for editing workflows — every editor handles PCM natively
4For VirtualDub compatibility, use AVI with Xvid, H.264, or HuffYUV — these are its best-supported codecs
5If the AVI file exceeds 2 GB, verify your target application supports OpenDML (AVI 2.0) format

MTS to AVI conversion gives editors frame-accurate, indexed video from AVCHD camcorder recordings, suitable for legacy NLE systems and scientific analysis tools that require the AVI container format.

Vanliga fragor

The H.264 stream from MTS can sometimes be copied to AVI with `-c:v copy`, but B-frames in the AVCHD stream may cause issues. Transcoding to a clean Baseline or lossless codec is more reliable.

Most modern editors handle MP4 fine. AVI is needed specifically for legacy software (pre-2010 NLEs, VirtualDub), scientific analysis tools, and workflows requiring lossless intermediate codecs.

HuffYUV lossless AVI from 1080p source is approximately 2-4 GB per minute. Uncompressed rawvideo is roughly 11 GB per minute. Storage requirements are substantial.

AVI can contain interlaced video, but most editing workflows benefit from deinterlacing first. Apply yadif or bwdif deinterlacing during the conversion.

AVI supports AC3 audio, but for editing compatibility, convert to uncompressed PCM (pcm_s16le). Every editor handles PCM without issues.

OpenDML (AVI 2.0) extends AVI beyond 2 GB to practically unlimited sizes. FFmpeg creates OpenDML AVI automatically when files exceed 2 GB. Most modern applications support it.
