AVI, introduced by Microsoft, is the standard video format for Windows machines. Macs, however, do not accept a number of codecs in AVI containers. As a result, you may have difficulty opening AVI files with Mac apps like Photos, Safari, QuickTime Player, iMovie, Final Cut Pro, etc.
MP4 is a universal video format with maximum compatibility and smaller size than AVI. Converting AVI to MP4 makes it play on Mac without hurdles. Here provides 4 methods to convert AVI to MP4 on Mac.
|Full name||Audio Video Interleave||MPEG-4 Part 14|
|Developer||Microsoft||Moving Picture Experts Group|
|Video quality||Support high-quality video without compression||Support high-quality video with efficient compression|
|File size||Large||Relatively small|
|Video codec||Video codec||MPEG-1, 2, 4, VP8, VP9, H.264/AVC, H.265/HEVC|
|Compatibility||Microsoft devices, Windows-based players, etc.||Almost all devices and players|
Video quality and file size: A video saved in an AVI container typically requires more space than one in MP4, since AVI does not support the H264 and H265 video compression standards. It is also possible to store 4K or 8K video in an MP4 container rather than AVI, which struggles to handle high-res video due to its antiquated nature.
Video codec: Even though you were able to see some AVI videos encoded in the H264 codec, they are still quite large and can't be opened on older devices. The fact is AVI format hasn't been specifically optimized to handle modern efficient video encoding.
The best-recommended software to turn AVI into MP4 on Mac is Cisdem Video Converter. AVI files encoded with any codec are supported, including DivX and Xvid. It's super fast without compromising image quality. If you want to play AVI videos, there's an AVI player integrated into Cisdem Video Converter, too.
Further, it supports video conversion between all kinds of SD/HD/4K formats, such as MKV to MOV, H264 to HEVC, MP4 to MP3, YouTube to MP4, AVI to Android, etc. To facilitate multiple conversions of AVI files at once, batch processing is allowed.
STEP 1. Load AVI files
Cisdem AVI converter for Mac has three interfaces. Drag-n-drop your AVI videos from local folder to the first one for video conversion.
STEP 2. Choose the desired output format – MP4
Click the format profile icon, and a drop-down list appears to bring up the format profile options. Pick up "General Video" > "MP4 Video” or “MP4 HEVC Video" (amazing visual quality while saving 50% bit rate).
It also covers a wide range of available pre-set devices, choose the Apple iPhone/iPad series, Android smartphones, game consoles, etc. as you like.
STEP 3. Edit AVI files (optional)
The program has useful video editing capabilities: crop AVI; create special effect/watermark/subtitle; etc. Click the icon to enter the video-editing mode.
STEP 4. Convert AVI to MP4 on Mac
Via “Output” at the bottom, choose the destination path to save the converted files. Finally, click the icon to begin converting AVI files to MP4 in bulk.
iMovie is an Apple-based video editor with the ability to edit video footage and export it as MP4 or MOV.
But not all types of AVI videos are supported by iMovie. AVI is a multimedia container format, not a specific type of file. It can be compressed by a quantity of codecs. Those AVI videos encoded with Indeo, native DivX, Cinepak, ALaw 2:1, Intel ITU H.263, etc. can’t be put onto iMovie.
So before turning AVI into MP4 on Mac, check if it’s an iMovie compatible video codec.
To convert AVI to MP4 on Mac with QuickTime player, three conditions need to be met:
If all three are met, then you can:
QuickTime X doesn't offer a video conversion option. However, when you open a playable AVI file in Mavericks or Mojave, it will automatically convert AVI to MOV. Since Catalina, the feature was abandoned.
As a powerful command-line tool, FFmpeg allows you to convert/stream/record video and audio files. Its advanced codec library - libavcodec ensures high portability and codec quality.
To use this open-source AVI to MP4 converter for Mac, you must know some basic coding techniques. Otherwise, you won't be able to start. The installation of FFmpeg is already very complicated for technical novices.
Online video converter is also a popular way for AVI conversion. Video.online-convert.com is a free online file converter. It has 7 parts: Audio converter, Video converter, Image converter, Document converter, E-book converter, Archive converter and Hash generator.
You can try this free online tool to convert AVI to MP4 on Mac, but don’t ignore its limits and drawbacks:
Yes, but not straightly.
Although VLC gives you an output option: Video- H.264 + MP3 (MP4), it's actually M4V. The M4V and MP4 formats are very similar. The main difference is that M4V might optionally be encrypted by DRM copy protection.
You can change the file extension to .mp4, but the video and audio are often corrupted or come with some serious lagging. If this happens, try to customize the profile:
In addition, when converting large AVI files (more than 500 MB), VLC stops short of the full conversion.
Obviously, VLC is not a good AVI to MP4 converter for Mac to get the task done.
HandBrake is a free video transcoder to convert videos from nearly any format including AVI, unprotected DVD, and BluRay sources. It lets you add multiple AVI files to the queue, and transcode them to MP4 in batches.
But it's not a perfect AVI to MP4 transcoder for Mac.
For those who are using Mac OS X 10.4.7+ and QuickTime 7 or previous, you are able to install Perian - the third-party component packages of QuickTime Player.
The best way is to look for alternatives to QuickTime. Both VLC and Cisdem Video Player are free to play AVI files on Mac.
The post shares the fastest and best ways to convert AVI to MP4 on Mac. To be honest, freeware is not an ideal choice due to the slow speed, low quality, complex operation, or limits. And online converters will let out your personal information. I believe a professional desktop AVI to MP4 converter for Mac is needed, which is safe, more stable, and gives you higher quality than other tools.
Megan has an impressive deal of experience with Mac software and has the ability to explain tech stuff in a simplified, straightforward and easy to understand way.
Thank you sooooo much. You were heaven sent!!! I am working on a 527MB of AVI video. It always stagnates when converting and it is a nightmare! You brought a great app to me and it worked like a charm.
