For controlling audio quality, see the AAC encoding guide. In the above example it uses the default quality of 23 for video, and 192 kBit/s constant bitrate for audio.Īs for audio, the static builds do not support libfdk-aac, but if you have support for it, you should use that instead: ffmpeg -i input.webm -c:v libx264 -c:a libfdk_aac output.mp4įDK-AAC gives you better quality than the internal AAC encoder. It is set with the -crf option, where the default is 23, and lower means better quality (typical values are from 18 to 28). Now to just right click on the file and select rename. Click the 'OK' button at the bottom of the dialog box. Click to uncheck the box for 'Hide extensions for known file types'. After that, you can add more videos for batch conversion. A dialog box with the title 'Folder Options' will appear. If it is needed, change the output format to one of the 37 video formats supported.

If you want to control the quality, have a look at the x264 encoding guide. Now your video is uploaded and you can start the WEBM to MP4 conversion. For that, the basic command would be: ffmpeg -i input.webm -c:v libx264 -c:a aac -strict experimental -b:a 192k output.mp4 Now, by "to MP4", I assume you mean to use H.264 and AAC as video and audio codecs, respectively. Sudo cp ~/Downloads/ffmpeg/ffmpeg /usr/local/bin/ Let's say you downloaded it to ~/Downloads/ffmpeg/ffmpeg, then do: sudo mkdir -p /usr/local/bin If you downloaded it manually (not with Homebrew), I would suggest copying the ffmpeg executable file to your PATH, so that you can use it from the Terminal. Convert WebM video files to many popular devices, such as iPhone, iPad, Samsung, PS4, TV, Xbox, etc. The online video converter is 100 free to convert WebM to MP4 online, as well as other video and audio formats.

Install it through Homebrew with brew install ffmpeg You can change basic video info and convert WebM videos online at the same time.
