Supports: MOV
MOV is Apple's QuickTime container — the native output of iPhone, iPad, Final Cut Pro, and most prosumer cameras that ship with QuickTime support. AVCHD (Advanced Video Coding High Definition) is the consumer HD camcorder spec developed by Sony and Panasonic in 2006: H.264 video plus AC-3 audio inside an MPEG-2 Transport Stream (.mts / .m2ts) arranged in a strict BDMV/ directory structure. The most common reasons to convert MOV → AVCHD:
PRIVATE/AVCHD/BDMV/STREAM/ for tape-style archival.BDMV/STREAM/ on a regular DVD-R or BD-R and standalone Blu-ray players from 2008 onward, plus PS4 and PS5, will play the disc like a real Blu-ray. No Blu-ray burner required when the runtime fits a DVD.| Property | MOV (QuickTime) | AVCHD |
|---|---|---|
| Container origin | Apple QuickTime (1991) | MPEG-2 Transport Stream (.mts / .m2ts, 2006) |
| Video codec | H.264, HEVC, ProRes, Animation, DV | H.264 only (Main / High profile) |
| Audio codec | AAC, ALAC, PCM, AC-3 | AC-3 (default) or LPCM |
| Resolution | Any (4K, 8K, anything) | 1080p / 1080i / 720p (HD only — no 4K) |
| Alpha / transparency | Yes (Animation, ProRes 4444) | No |
| Disc authoring | Not a disc format | Plays on Blu-ray / PS4 / PS5 from BDMV/ folder |
| Camcorder ingest | Not accepted | Native — Sony, Panasonic, JVC HD camcorders |
| Native playback | macOS, iOS, QuickTime | Sony / Panasonic camcorders, Blu-ray players, PS4 / PS5 |
| Best for | Mac editing, lossless intermediates, iPhone capture | Camcorder workflows, AVCHD discs, legacy HD NLEs |
| Setting | CRF | Approx bitrate (1080p) | Best for |
|---|---|---|---|
| Highest | 18 | 24-30 Mbps | Mastering, disc authoring, near-source |
| High | 20 | 18-22 Mbps | High-quality archive, Blu-ray-on-DVD |
| Medium (default) | 23 | 12-16 Mbps | Camcorder re-ingest, general AVCHD |
| Low | 26 | 6-9 Mbps | Long-form footage on a single SD card |
| Lowest | 28 | 3-5 Mbps | Maximum runtime on small media |
Note: AVCHD spec caps peak video bitrate at 24 Mbps for AVCHD 1.0 and 28 Mbps for AVCHD 2.0 (Progressive). If a downstream device rejects the file, drop the bitrate below 24 Mbps.
They're closely related. MTS is the raw filename extension AVCHD camcorders write directly to SD card. M2TS is the same content used inside the AVCHD BDMV/STREAM/ folder structure on a disc. AVCHD is the overall spec — the folder structure plus the stream format. Our converter outputs the stream that both extensions wrap; pick the .mts or .m2ts variant if you need a specific extension, or stick with AVCHD for the folder-ready file.
If the camcorder supports AVCHD ingest (most Sony Handycam, HDR-CX/PJ, FX, and Panasonic HC-V / HC-X models do), yes — copy the converted MTS file into the PRIVATE/AVCHD/BDMV/STREAM/ folder on the SD card and the camcorder will see it. Older bodies may also need the index files refreshed; some manufacturer utilities rebuild that automatically.
Yes — that's one of AVCHD's main use cases. Place the MTS file inside BDMV/STREAM/ on a regular DVD-R, add the standard BDMV/ index files (most disc-burning apps add these automatically when you select "AVCHD disc"), and any Blu-ray player from 2008 onward, plus PS4 and PS5, will play it as a Blu-ray-style disc — no Blu-ray burner needed.
Yes. ProRes 422, ProRes 4444, and ProRes Proxy all decode on the way in and re-encode to AVCHD-compliant H.264. Expect a notable size drop because ProRes is an intra-frame mastering codec (large) and AVCHD H.264 is a heavily inter-frame delivery codec (small). Alpha-channel content from ProRes 4444 is flattened — AVCHD has no alpha support.
No. AVCHD caps at 1080p (1920×1080 progressive, 1440×1080 interlaced). The converter downscales 4K MOV sources to 1080p when AVCHD is selected. If you need to keep 4K, output to MP4 or MKV instead.
Yes. iPhone recordings (HEVC inside a MOV wrapper) decode on input and re-encode to AVCHD's required H.264. The audio track is re-encoded from AAC to AC-3. Dolby Atmos / spatial audio metadata is dropped — AVCHD targets stereo or 5.1 AC-3 only.
If your MOV used HEVC (the iPhone default since iOS 11), AVCHD's mandatory H.264 re-encode is roughly 30-50% less efficient — same visible quality, larger file. Drop the CRF to 25-28 or pick the Low quality preset to claw the size back. Conversely, ProRes MOVs shrink dramatically — a 90-minute ProRes 422 MOV typically lands at 6-10 GB in AVCHD at default settings.
Only the primary audio track converts (re-encoded to AC-3). MOVs carrying multiple language tracks or commentary tracks see only the first stream survive — AVCHD consumer devices expect a single primary audio stream. If you need every track preserved, keep the source MOV or convert to MP4 instead.
The converter outputs the stream file (the .mts content). The surrounding BDMV/INDEX.BDM, BDMV/MOVIEOBJ.BDM, and BDMV/PLAYLIST/00000.MPL index files are generated by your disc-authoring app (multiAVCHD, tsMuxeR, ImgBurn with AVCHD template, or built-in tools in Vegas / EDIUS). Drop the converted .mts into the authoring app's input list and it builds the folder structure for you.
