Why Convert MPEG to AVCHD?
AVCHD (Advanced Video Coding High Definition) was developed by Sony and Panasonic for HD camcorder recording. It uses H.264 video with AC3 (Dolby Digital) audio in an MPEG transport stream container. Converting MPEG to AVCHD is useful for importing video into AVCHD-based editing workflows (Sony Vegas, Adobe Premiere), preparing content for Blu-ray disc authoring where AVCHD is a native format, upgrading legacy MPEG-2 video to efficient H.264 compression, and creating files compatible with Sony and Panasonic camcorder media management software.
MPEG vs AVCHD Comparison
| Feature | MPEG | AVCHD |
|---|---|---|
| Video codec | MPEG-1 or MPEG-2 | H.264 (default) |
| Audio codec | MP2 | AC3 / Dolby Digital (default) |
| Compression efficiency | Low (MPEG-2) | High (H.264, ~2× better) |
| Blu-ray compatible | Requires conversion | Native support |
| Camcorder support | None | Sony, Panasonic (native) |
| Surround sound | Stereo only | 5.1 surround (AC3) |
| Best for | DVD, legacy playback | Blu-ray, HD camcorder workflows |
AVCHD Audio Options
| Codec | Channels | Best For |
|---|---|---|
| AC3 (default) | Up to 5.1 surround | Blu-ray, home theater |
| AAC | Stereo or surround | Smaller files, Apple devices |
Why is AC3 the default audio codec?
AC3 (Dolby Digital) is the standard audio codec for AVCHD and Blu-ray disc content. It supports 5.1 surround sound, which is required for Blu-ray authoring. Use AAC instead if you only need stereo audio and want smaller files.
Will the file size decrease?
Yes, typically. H.264 is roughly 2× more efficient than MPEG-2. A 2 GB MPEG file often becomes 1 GB or less as AVCHD with H.264 at equivalent visual quality.
What resolution should I use for Blu-ray?
Blu-ray supports 1080p (1920×1080) and 720p (1280×720). Under Video Resolution, choose the 1080p or 720p preset. Use H.264 video with AC3 audio for maximum Blu-ray compatibility.
Can I trim the video during conversion?
Yes. Under Trim, select "Time Range" and enter a Start Time and Duration in seconds or HH:MM:SS.sss format.
What is the difference between AVCHD and MTS?
AVCHD is the format specification; MTS and M2TS are the file extensions used by AVCHD files. AVCHD files contain H.264 video in an MPEG transport stream — functionally similar to MTS but with additional metadata structure for camcorder compatibility.
