If you are a movie lover like me, you probably have had reasons to download movies from open-source platforms. The reason for this can be personal, but in my case, the movies are either not available on my paid streaming platforms or I may just need to set up another streaming app to access the movie. If you are like me, you would agree that it’s such a hectic task. The solution? For me, I just check for an open-source platform to download the movie, but even at that, this method is not completely hitch-free.

I’ve downloaded my fair share of videos from the internet, so imagine my surprise when one day, I downloaded one and couldn’t play it on my local video player. After a few minutes of trying to figure out what the problem could be, I realized it was because they were formatted in AVCHD, a video format commonly used for recording HD video on today’s digital cameras. This video format typically uses the MPEG-4 AVC/H.264 codec for video compression, which results in great video quality and a relatively small file size.

However, AVCHD isn’t widely supported across video playing software, which is why I encountered the aforementioned challenge, and was advised by the internet to convert to MP4. Out of curiosity, I explored every MP4 converter I could find, from free classics like VLC to pro tools like HandBrake, and quick online converters like Movavi Video Converter. In this guide, I’ll walk you through a list of apps that make converting AVCHD to MP4 easy, explain why I picked each one, and highlight what each tool does better than the rest.

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.

Frequently asked questions

▶️ What is AVCHD?

AVCHD stands for Advanced Video Coding High Definition, a format developed by Sony and Panasonic for recording HD video on camcorders. It’s known for preserving high-quality video and audio while keeping file sizes relatively minimal. However, AVCHD files can be large and aren’t always supported by all devices or media players, which is why many people convert them to MP4.

▶️ Which format is better – AVCHD or MP4?

Neither format is strictly better than the other. It depends on your needs. AVCHD is ideal for keeping the highest video quality, especially if you’re editing or archiving footage. MP4, on the other hand, is more versatile and works across most devices, platforms, and apps, making it the better option for sharing and everyday use.

▶️ How do I convert AVCHD to MP4 on a Mac?

On a Mac, you can use tools like Movavi Video Converter, VLC, or Handbrake to convert AVCHD to MP4. The process usually involves importing your AVCHD file, choosing MP4 as the output format, and starting the conversion. Most of these programs are straightforward, and some even allow you to tweak resolution or file size for the best results.

▶️ Can I import AVCHD files into my Android phone?

Directly importing AVCHD files to an Android phone is tricky because the format isn’t widely supported on most mobile devices. To play your videos smoothly, it’s best to convert AVCHD to MP4 first, using a desktop or online converter like Movavi Video Converter, Handbrake or VLC. Once converted, the MP4 files can be transferred via USB, cloud storage, or even messaging apps.

▶️ How do I transfer AVCHD files to my iPhone?

Like Android, iPhones don’t natively support AVCHD files. The easiest method is to convert your AVCHD video into MP4 on your computer first, then transfer it to your iPhone using iTunes, Finder, or AirDrop. Once it’s in MP4 format, you can watch, edit, or share the video on your iPhone without any compatibility restrictions.
