FFmpeg<\/a> is a great command-line tool for dealing with audio and video files. Here are some useful commands:<\/p>\n\n\n\n

1. Reduce the size of a file<\/span><\/b><\/p>\n\n\n\n

Try passing the file straight through ffmpeg<\/code> and check if the size reduces:<\/p>\n\n\n\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
ffmpeg -i input.mp4 output.mp4<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n\n\n\n

To reduce the size further, scale the video to half the width and height:<\/p>\n\n\n\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
ffmpeg -i input.mp4 -vf <\/code>\"scale=iw\/2:ih\/2\"<\/code> output.mp4<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n\n\n\n

2. Convert a MOV file to MP4<\/span><\/b><\/p>\n\n\n\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
ffmpeg -i input.mov -vcodec h264 -acodec aac -strict -<\/code>2<\/code> out.mp4<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n\n\n\n

3. Create a video from an image by panning across it<\/span><\/b><\/p>\n\n\n\n

If you have a landscape image, first set its height to 1600px, preserving aspect ratio (using an image editor such as IrfanView<\/a>). Then run the following command to create a video which pans across the image from left to right:<\/p>\n\n\n\n

\n
\n\n\n\n
\n
1<\/div>\n<\/td>\n
\n
\n
ffmpeg -loop <\/code>1<\/code> -i input.jpg -vf crop=<\/code>1200<\/code>:ih:<\/code>'min((iw\/10)*t,9*iw\/10)'<\/code>:<\/code>0<\/code> -t <\/code>5<\/code> out.mp4<\/code><\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n\n\n\n
