AVCHD, instead of MMV, is now widely used in recodings in Sony’s camcorders and it is acting as a video file and can be played through QuickTime player or IINA via double click on macOS. However, when I try to load AVCHD for converting to MP4 or MKV, I have little trouble trouble but is able to fix it myself and want to share my experiences of how to convert AVCHD to MP4 or MKV, mainly on macOS including macOS Sierra, High Sierra. But the guide will also apply to WMV, AVI or MPEG converting of AVCHD on both PC and Mac.
When I try to load AVCHD to two of my AVCHD MTS converters MacX Video Converter Pro and Wondershare Video Converter Ultimate and find them not recognizing my AVCHD files Sony camcorder recorded. MacX Video Converter Pro does not recogize the files either from my camera, resp. from the SD memory card on my MacBook Pro. AVCHD is also grey out when you try to add it via Add Files button in Wondershare Video Converter Ultimate.
MTS Video Files in AVCHD
As I am also running Windows, I find something different how AVCHD acts in macOS than in Windows. macOS is very helpful in handling those kinds of folder structure movies, like AVCHD, for editing in FCP or iMovie, but if you come across a problem importing AVCHD to video converters for further converting, you are supposed to follow the guide below and locate the actual video files in .mts that are all hidden in Mac OS X Mountain Lion and later.
- Hold Control and click AVCHD or right click AVCHD and click Show Package Contents
Hold Control and click BDMV or right click BDMV and click on Show Package Contents
- Inside, you will see a folder called STREAM. Double click the STREAM folder you will see the .mts video files there
Though this way you are able to add AVCHD for any AVCHD MTS converter supports MTS for converting. When comparing MacX Video Converter Pro and Wondershare Video Converter Ultimate, I’d like to recommend Wondershare as best way out as it supports dragging and dropping AVCHD to the program instead of locating the MTS media file in AVCHD for converting. And my below shows you to use the very AVCHD MTS converter to convert your camcorder files in AVCHD to any file like MP4, MKV, AVI, WMV as well as devices like iPhone/iPad and Andriod-based phones, tablets and TVs.
Convert AVCHD to MP4 MKV AVI WMV
Wondershare Video Converter Ultimte is said to be able to convert AVCHD, MTS/M2TS, MKV or any other HD & SD videos with its built-in engines to support up to 350 video and audio codecs in MPEG4, H264, VP8, DivX, Xvid etc including the 4K and 3D formats. Let’s see how Wondershare works with AVCHD files and convert them to MP4 MKV AVI WMV.
Step 1. Getting Ready
Follow the below two buttons to have a free trial version of Wondershare Video Converter for AVCHD. If you already have it, please go for step 2.
Step 2. Loading AVCHD
You are able to manualy locate the MTS file in STREAM folder mentioned above and drag one or more to the AVCHD converter but you can drag it directly to AVCHD! Wondershare will let you choose what to convert if there is one more MTS files in AVCHD. When you drag to load, Wondershare shows your loading Camcorder Files as shown below:
If there is more than one MTS files in the AVCHD, Wondershare will ask you to choose which to add and convert:
Step 3. Choose Output Profile
MP4 comes as the default output profile for converting AVCHD in Wondershare. You are always free to choose another in “Convert all tasks to” or custom your own via the Edit button on the right.
Step 4. Converting AVCHD to MP4 MKV
If there is no edit or merge needed, you can just hit Convert All to start converting. If you convert it to MP4, you are supposted to enjoy your AVCHD files on any computers or devices.
Besides, there is one thing that I have to point out that even you are able to drag or remove the mts files out does not mean you should. You will always need the special structure on Mac OS X to import into FCP X. So, it is better to leave the AVCHD in its original type.
