#2 VLC – Open Source Software to Convert Individual FLV Video

When it comes to VLC, we all know that it's a famous media player to play any multimedia files and DVD. It's also packed with a hidden feature - convert videos with limited supported formats.

You have to accept its imperfections if you use VLC. It can merely convert one FLV video at a time, and there may be errors with codecs.

Steps to convert FLV to MP4 Mac via VLC:

1. Run the program. Navigate to “File” > “Convert/Stream” to open the conversion window.
2. Drag and drop an FLV file into the free FLV converter for Mac.
3. Select MP4 as the output format under “Choose the Profile”.
4. Click the “Customize” button beside the format option. Under the 'Audio Codec' tab, tick the box 'Keep original audio tracks'. (Important step for saving as MP4 format)
5. Click 'Save as File'. Name the converted MP4 and choose the output destination.
6. Hit “Save” in the lower right corner of the main panel.

Even though you have selected MP4 as the output, VLC will still turn FLV into M4V format. M4V is a division of MP4, sharing lots in common with MP4. It’s designed for Apple products and opened in iTunes by default, which means if you want to play FLV resources on an Apple device, you can go with this FLV-M4V conversion.

To use MP4 instead, simply change the extension to .mp4. Note: If step4 is missing, the video after changing the extension can't be played.

#3 HandBrake – Bulk Convert FLV Files for Free, But Slow

HandBrake is a free FLV converter for Mac with limited editing features, like tweaking video/audio parameters, adding subtitles, importing chapters, etc.

It's able to convert various videos and DVDs to MKV and MP4. In addition to these two output formats, HandBrake has no more options.

tips: HandBrake itself can’t convert protected commercial DVDs. To unlock the function, you have to install the software library - libdvdcss (aka. libdvdcss2).

Steps to batch convert FLV to MP4 Mac using HandBrake:

1. Run HandBrake. A dialog for adding a video file will pop up automatically.
2. Import an FLV file. It doesn't let you import bulk files directly.
3. Choose the output format – “MP4 File”, and edit dimensions, filters, etc. as needed.
4. Hit “Browse” to select a destination path for your encode.
5. After finishing the setup, add FLV to queue. To add more FLV files, repeat this operation - click 'Open Source' to upload video > 'Add to Queue'.
6. Open the Queue window, click “Start” to extract FLV to MP4 on Mac.

How to Convert FLV to MP4 on Mac Free Online?

Zamzar.com is considered the best free online FLV converter for Mac. It enables you to convert FLV to MP4 without watermark or time limit online. More than a video converter, it also converts audio files, images, documents, etc.

It says that the size of the uploaded file cannot exceed 50MB. According to my test, the maximum is 400MB. But once file size exceeds 50MB, the conversion speed will be very slow. Plus, you can only convert up to 5 FLV videos to MP4 at once.

1. Visit https://www.zamzar.com/ site.
2. On the home page, hit 'Convert Files' to import FLV.
3. In the next box, select your desired format - mp4.
4. Click the 'Convert Now' button. Wait patiently for the process.
5. Download the MP4 videos.

How to Change FLV to MP4 on Mac with Command Line Tool?

FFmpeg is a command line FLV converter for Mac with the ability to convert between most video and audio formats. It also lets you set the different codec to use for each stream.

For non-technical users, FFmpeg is not recommended. Its extremely complicated installation alone can scare you off.

1. Install FFmpeg to your Mac. (Check the tutorial)
2. Activate Terminal app and go to where your file is stored.
3. Use the command: ffmpeg -i input.flv output.mp4.
   Type ffmpeg(if it's not in your path, you should enter its full path), –i, drag an FLV file into Terminal, and then type xxxx (resulting file name).mp4.
4. Press “Enter” to transcode the video.

You can also input the command: ffmpeg -i input.flv -c copy -copyts output.mp4 to remux FLV into MP4 instead of re-encoding it. Remuxing only copying video and audio streams to another container, no substantial changes.

To batch covert a folder of FLV, enter for f in *.flv; do ffmpeg -i '$f' -c copy '${f%flv}mp4'; done.

Quick Q&A

1) What is FLV?

Flash video, also abbreviated as FLV, is a container file format. It transmits digital video content through Adobe Flash Player or Adobe Air on Internet.

There are 2 types of flash video: FLV and F4V (new type of flv), we can generally describe their relationship as equivalent to that of .doc and .docx.

FLV can be used to deliver different video contents, movies, TV shows, presentation, animation, advertisement, etc. It’s web-friendly in file size, making it easy to upload and download.

2) Why convert FLV to MP4 on Mac: FLV vs. MP4

FLV	MP4
Internet search	Not recognized by search engine spiders	Easily accessible
Video quality	Small size but not pay attention to quality	Higher compression, less quality loss
Compatibility	Support most web browsers but relative lower compatibility with mobile devices	Accepted by almost all programs and devices (Apple products, Android devices, etc.)
Play file	Need to install Flash Player plug-in	No plug-in required
Battery life	Consume more power	Consume less power

Obviously, MP4 is superior to FLV in the above aspects. But the major reason to extract FLV files to MP4 on Mac lies in the poor compatibility of FLV. You are unable to open FLV on Mac via QuickTime, iTunes, iMovie, or others.

3) How do I turn FLV into MP4 through OBS Studio?

OBS Studio is a free screen recorder and video editor that aims at mixing media files and recording game/live streaming. Same as FFmpeg, it’s able to remux FLV into MP4 on Mac without re-encoding.

1. Initiate OBS Studio. On the menu bar, click “OBS” > “Preferences” to open the “Settings” window.
2. In the “Output” tab, select the recording format as MP4. Click “OK”.
3. Head to “File” > “Remux Recordings”.
4. Drop FLV videos into the “Remux Recordings” window.
5. Hit “Remux”.

However, when you encounter power loss, blue screen of death, BSODs, etc. during the recording process, the MP4 file will be unrecoverable, which is caused by the structure of MP4.

OBS team suggests setting the recording format as FLV or MKV (good for multiple audio tracks). They can record safely even if your computer meets issues.

Therefore, you'd better record FLV files with OBS, and then convert them to MP4 with other tools.

4) Can Adobe Premiere export FLV as MP4 on Mac?

Yes, Adobe Premiere supports 10+ resulting formats, including MP4.

But the software is not a dedicated FLV to MP4 converter for Mac. It’s an industry-leading video editor for film, TV, and the web.

5) What’s the best FLV player for Mac?

After the FLV file is changed to MP4, it can be viewed on any platform. if you still need an FLV player, give a try on VLC, Cisdem Video Player, or install Perian for QuickTime.

Final Thoughts

No matter which way you choose to convert FLV to MP4 on Mac, make sure if they can meet your basic needs on video conversions, an all-in-one video converter for Mac is always the one saving time and effort.
