Part 1: How to install and use FFmpeg on Windows 10 <\/strong><\/h2>\n

<\/a><\/div>\nHere we would show you how to install and use FFmpeg on Windows 10. You could follow the below guide to learn the details.<\/p>\n
1.<\/b> You need to download the latest FFmpeg build from the official FFmpeg website<\/strong><\/a>. You can either Download the 32-bit version or 64-bit version that suits your system. Click the Download Build button to start downloading.<\/p>\n
2.<\/b> You need to add a program to system path using Environment Variables to make FFmpeg work directly on Windows 10.<\/p>\n
3.<\/b> Navigate to the downloaded folder where the FFmpeg zip file is a store. Right-click on the Zip folder and click extract from the drop-down menu.<\/p>\n
4.<\/b> Right-click on the extracted folder and click Rename from the drop-down menu with title FFmpeg-20180424-d9706f7-win64-static to FFmpeg.<\/p>\n
5.<\/b> Copy the FFmpeg folder and navigate to C drive. Paste the folder to the root of C drive.<\/p>\n
6.<\/b> To use FFmpeg in Command Prompt, you need first to add the bin folder containing the FFmpeg executable file to your Windows path.<\/p>\n
7.<\/b> Navigate to Advanced button and click Environment Variables at the bottom of the window.<\/p>\n
8.<\/b> In the Environment Variables window, Select the variable Path and click Edit to change the Path variable.<\/p>\n
<\/a><\/div>\n9.<\/b> Click New and type the path of FFmpeg folder \u201cC:\\ffmpeg\\bin\\\u201d and click OK.<\/p>\n
10.<\/b> Type the path directory according to the drive or folder where you have placed FFmpeg folder.<\/p>\n
11.<\/b> Once done, the path gets added to the Environment variables. Click OK to apply changes.<\/p>\n
With all these changes, you then only need to verify if FFmpeg is installed successfully. Launch Command Prompt and type the command FFmpeg in the command prompt terminal and hit Enter.<\/p>\n
<\/a><\/div>\nIf the FFmpeg is added properly to Windows Path, the command prompt will display the details about FFmpeg like its version number, configuration, etc. If you weren\u2019t successful, it only means that your command prompt did not recognize the commands. Cross check to see if you have added the FFmpeg folder to the system path properly.<\/p>\n
Then, you could freely use FFmpeg to handle video files on your computer as you like.<\/p>\n
Part 2: How to install and use FFmpeg on Mac<\/strong><\/h2>\n
On a Mac, you can install FFmpeg using Homebrew which is a superb package manager for the MacOS ecosystem. Here is the one-liner to install FFmpeg on a Mac machine (testing and working on Cataline v 10.15.5).<\/p>\n
\n- \n
- 1.<\/strong> Firstly, install Homebrew. <\/li>\n
- 2.<\/strong> Then install FFmpeg through the ffmpeg formula: brew install ffmpeg <\/li>\n
- 3.<\/strong> This will download a lot of dependencies such as x264, but after that you should be good to go. <\/li>\n
- 4.<\/strong> To update ffmpeg later on, run: brew update && brew upgrade ffmpeg <\/li>\n<\/ul>\n<\/div>\n
If you want additional tools like Netflix\u2019s VMAF on MacOS with FFmpeg, all you need to do is to include if when you install ffmpeg. For example: brew install ffmpeg --with-libvmaf<\/p>\n
The brew page is an excellent resource for all the possible options.<\/p>\n
Part 3:How to crop a video using FFmpeg after running this program successfully <\/strong><\/h2>\n
Then, let\u2019s go to the main topic: how to crop a video using FFmpeg without losing video quality.

<\/a><\/div>\nOr, you could try the below solutions to make use of the crop feature within FFmpeg. the below are the crop command:<\/p>\n
\n- \n
- ffmpeg -i in.mp4 -filter:v \"crop=out_w:out_h:x:y\" out.mp4<\/strong><\/li>\n<\/ul>\n<\/div>\n

ffmpeg -i in.mp4 -filter:v \"crop=80:60:200:100\" -c:a copy out.mp4<\/span><\/p>\n
2. To crop the bottom right quarter<\/b>, just try these commands:
\n\u201cffmpeg -i in.mp4 -filter:v \"crop=in_w\/2:in_h\/2:in_w\/2:in_h\/2\" -c:a copy out.mp4<\/span>\u201d
\n\u201cffmpeg -i in.mp4 -filter:v \"crop=320\/2:240\/2:320\/2:240\/2\" -c:a copy out.mp4<\/span>\u201d
\n\u201cffmpeg -i in.mp4 -filter:v \"crop=160:120:160:120\" -c:a copy out.mp4<\/span>\u201d<\/p>\n3. Crop 20 pixels from the top<\/b>, and 20 from the bottom:
