When recording videos, you may don’t know to choose which video formats to record in, AVCHD or MP4. These two formats are the most popular video file formats for storing recorded videos. Among camcorder users, AVCHD vs MP4 has become a hot topic.

To make a choice between these two formats, you need to understand what they are, what the difference between AVCHD and MP4 is, and their advantages & disadvantages. Besides, if you want to convert AVCHD to MP4 or vice versa, some converters are recommended.

What Is AVCHD?

AVCHD is short for Advanced Video Coding High Definition that is a file-based format for the high-definition video’s digital recording and playback. This format was developed by Sony and Panasonic and it is mainly used in high definition consumer camcorders.

For video compression, AVCHD uses the H.264/MPEG-4 AVC standard. For audio compression, this format supports Dolby AC-3 and uncompressed linear PCM audio.

AVCHD was improved to include stereoscopic video and 1080-line 50-frame/s and 60-frame/s modes in 2011. This means this format has double the data rate compared to the previous modes.

It is worth mentioning that AVCHD is compatible with the Blu-ray disc format. That is, you can directly burn the AVCHD videos to Blue-ray discs and DVDs without any format conversion.

What Is MP4?

MP4, also known as MPEG-4 Part 14, is a popular digital multimedia container format that can be used to store videos, audios, subtitles and still images as a single file. Since MP4 works by compressing the files making the overall size much smaller, it is easy to stream over the Internet and access & play videos.

Besides, MP4 can hold a variety of data as well as the size reduction, making it an ideal option for offline and online use.

The MP4 file format is based on the QuickTime format that was published in 2001. Also, it was part of the ISO Base Media File Format ISO/IEC 14496-12:2004, which defines a general structure for time-based media files.

For more information on MP4, refer to our previous post – What Is MP4 and What Are the Differences Between It and MP3.

AVCHD VS MP4: What’s Difference Between Them?

After learning what AVCHD and MP4 are, now let’s make a comparison to help you know which one to choose.

File Extension

From a layman’s perspective, the most obvious difference between these two formats is the file extension. In general, once the AVCHD-formatted video is processed and transferred to a computer, it is stored with the .m2ts extension in a file with the PMB (Picture Motion Browser) software.

While the MP4-formatted video uses .mp4 file extension saved with the PMB software. Although they use the same video codec, the container format they use is different.

In this aspect, they fight to a standoff.

Video and Audio Codecs

From a technical perspective, the audio codecs that these two formats use are different greatly. AVCHD uses Dolby AC-3 as the audio codec whereas MP4 uses MPEG-4 AAC-LC codec. As to the video codec, both of them use MPEG-4 AVC/H.264.

Although they use different audio codecs, there is no much difference in the quality they produce. Thus, in terms of codes, no winner exists in AVCHD vs MP4.

Video Quality

Sony and Panasonic devices capture the highest resolution quality images in AVCHD only. This format records HD (1080i, 1080p, and 720p) and SD videos. But JVC captures MP4 up to 1080p at 60 frames per second. That is, the quality of MP4 is inferior to AVCHD.

If you regard quality as important, the AVCHD video format is your good choice and it wins hands down in AVCHD vs MP4.

File Size

Due to the high-quality video image, AVCHD is very popular among consumers. But high quality means an over-large file size. However, the MP4 video file is small.

Usually, a 30-minute AVCHD video with 1920*1080 resolution can take up 300-400MB while the file size of an MP4 video is only 100MB.

Besides, MP4 also supports HEVC/H.265 codec, so it can offer smaller file size at the same quality than H.264.

In conclusion, an MP4 file takes up 3 times less space compared to an AVCHD file. If you concern about the file size, MP4 is your choice.


In terms of AVCHD vs MP4, compatibility shouldn’t be the factor that you ignore. AVCHD can be compatible with Blu-ray Disc format, xv.Color technology, and several recording media devices like memory sticks or hard disks.

But compared to MP4, the compatible devices are less. MP4 is a universal format that is famous for its perfect compatibility with a large number of recording media and networks, players, and more. Besides, it works well with Apple QuickTime format.

This shows MP4 wins in compatibility. This is why many of you convert other video formats to MP4 for better compatibility, for example, WAV to MP4, VOB to MP4, etc.


Technically speaking, the AVCHD format is suitable for creating AVCHD and Blu-ray Disc recordings and watching on an HDTV.

For MP4, it can be saved as a single movie file and can be easily moved, copied, uploaded, and shared via the web or hard disks. You can play the MP4 video on multiple devices including Android, iPhone, QuickTime, VLC, iMovie, Windows Media Player, etc.

In usage, the winner is MP4.
