The good news is you don’t have to force yourself to learn about AVCHD. You can simply convert them into a different format like MP4 or FLAC. Doing so will save you from the trouble of learning about this unfamiliar format and since you’re most likely well-versed in MP4, the perfect option is to convert AVCHD to MP4.

Part 1. How Do I Open an AVCHD File?

AVCHD is a file specifically meant for studio recordings. This format is usually utilized by people using camcorders. Its codec is the same as MP4 although it uses Dolby AC-3 for its audio. The main selling point of AVCHD is that its compression is top-notch, resulting in a very small file size while still maintaining good quality. Hence, it’s the perfect format for Blu-ray.

AVCHD playback is easy if you have the correct media player. Of course, you can use AVCHD discs or Blu-ray if you only plan on watching the video. However, if you want to deal with edits afterward, you can use the following media players:

  • Windows Media Player. Playing AVCHD files on WMP is the perfect option for Windows users since this media player is installed by default. Moreover, such a media player supports numerous formats and if there is an error, you can easily solve it by updating the program.
  • As usual, VLC supports this format, especially since you can also add unfamiliar video and audio codecs to the platform. Since it’s free, you can enjoy this media player without restraints.
  • Media Player Classic. If you’re more into lightweight media players, I suggest looking into Media Player Classic. This software supports hundreds of formats. On that of that, this player is open-source, so you can install useful plugins to extend its functions.

Regardless of which media player you use, you’ll eventually end up seeing that other formats are much better than AVCHD in several aspects. For that reason, we’ll proceed to how you can convert AVCHD to MP4.
