- Frame Rate: Users can specify the frame rate of the output file using the -r option. For example, to convert a MOV file to an MP4 file with a frame rate of 30 fps, the following command can be used: ffmpeg -i input.mov -r 30 output.mp4
Audio Options
FFmpeg also provides a range of options for customizing the audio output. Users can specify the audio codec, bitrate, and sample rate, among other options. For example, to convert a MOV file to an MP4 file with AAC audio and a bitrate of 128 kbps, the following command can be used:
ffmpeg -i input.mov -c:a aac -b:a 128k output.mp4
This command specifies the AAC codec for audio and sets the bitrate to 128 kbps.
Merging Multiple Files
FFmpeg can also be used to merge multiple files into a single output file. This can be useful for combining multiple video clips or adding audio to a video file. To merge multiple files, users can use the -f option to specify the input format and the -i option to specify the input files. For example, to merge two MOV files into a single MP4 file, the following command can be used:
ffmpeg -f concat -i input1.mov -i input2.mov output.mp4
This command tells FFmpeg to concatenate the two input files and convert them to a single MP4 file.
