What is AVCHD? The AVCHD video format is commonly used for recording HD video on today’s digital cameras. It uses the MPEG-4 AVC/H.264 codec for video compression, which results in great video quality and a relatively small file size. However, you may encounter problems with AVCHD because of its low support.
Here are some issues you may come across.
AVCHD is not supported on your device
The AVCHD format is not recognized by most mobile devices, so if your device is one of those, convert your video to a more device-friendly format like MP4 which is much more widely supported.
It’s impossible to share an AVCHD clip on social networks
AVCHD is not among the formats recommended for video uploading, at least for YouTube and Facebook. Even if you manage to upload your clip, the quality may be reduced, so it’s better to convert it to a more compatible format like MP4 in advance.
There's no sound in your video
This might be an audio codec problem. Try to change it by converting your video file to another format with a different codec, e.g., MP4. The right software will help you do this without losing video quality.
In the guide below, we describe different ways to convert AVCHD files to MP4, compare AVCHD and MP4, and answer some questions you may have.

Frequently Asked Questions
What is AVCHD?
Advanced Video Coding High Definition (AVCHD) is a video format invented by Canon, Panasonic, and Sony. The intention was to create the most efficient codec for recording videos, and many camcorders now use AVCHD format to store videos that they record. AVCHD can compress information into very small file sizes, making it ideal for storing information on smaller personal video cameras while maintaining high definition quality. Blu-ray supports AVCHD video as well, which also takes advantage of smaller file sizes to deliver high-quality video, meaning it can be very easy to create Blu-Ray discs from your AVCHD cameras. These files are saved on camcorders as MTS files, but once moved to another device, they become M2TS files, which are the specific type of AVCHD file that plays on a Blu-ray.
How do I play AVCHD?
While there are a number of ways to play an AVCHD video, one of the easiest and most accessible is using a free AVCHD player like VLC. It is a powerful converter as well as an amazing tool for playing many file formats, including AVCHD. To play an AVCHD file in VLC, it's as easy as simply clicking the Media button in the top left, clicking Open file, and browsing for the file you want. No conversion or editing necessary.
Which format is better – AVCHD or MP4?
It depends on what you need your file for. AVCHD has better video quality, but the file size is relatively large and format support is limited. MP4 has better compression, smaller file size, and is supported by almost every device.
