Use the size (-s) switch with ffmpeg to resize a video while maintaining the aspect ratio.įfmpeg -i input.mp4 -s 480x320 -c:a copy output.mp4 12. You can also specify the -shortest switch to finish the encoding when the shortest clip ends.įfmpeg -i video.mp4 -i audio.mp3 -c:v copy -c:a aac -strict experimental output.mp4įfmpeg -i video.mp4 -i audio.mp3 -c:v copy -c:a aac -strict experimental -shortest output.mp4 11. This command saves image frames from the video after every 4 seconds.įfmpeg -i movie.mp4 -r 0.25 frames_%04d.png 10.

You can use FFmpeg to automatically extract image frames from a video every ‘n’ seconds and the images are saved in a sequence. You can also use the -s switch (like -s 400x300) to specify the exact dimensions of the image file though it will probably create a stretched image if the image size doesn’t follow the aspect ratio of the original video file.įfmpeg -ss 00:00:15 -i video.mp4 -vf scale=800:-1 -vframes 1 image.jpg 9. This command will extract the video frame at the 15s mark and saves it as a 800px wide JPEG image. Use the scale filter to specify the width of the GIF, the -t parameter specific the duration while -r specifies the frame rate (fps).įfmpeg -i video.mp4 -vf scale=500:-1 -t 10 -r 10 image.gif 8. Convert a video into an animated GIFįFmpeg is an excellent tool for converting videos into animated GIFs and the quality isn’t bad either. The -vn switch extracts the audio portion from a video and we are using the -ab switch to save the audio as a 256kbps MP3 audio file.įfmpeg -i video.mp4 -vn -ab 256 audio.mp3 7. Use the -an parameter to disable the audio portion of a video stream.įfmpeg -i video.mp4 -an mute-video.mp4 6. Mute a video (Remove the audio component) Create an input file with a list of all source files that you wish to concatenate and then run this command.įfmpeg -f concat -i file-list.txt -c copy output.mp4 5. If you have multiple audio or video files encoded with the same codecs, you can join them into a single file using FFmpeg. Encoding a video takes time but you can speed up the process by forcing a preset though it would degrade the quality of the output video.įfmpeg -i youtube.flv -c:v libx264 filename.mp4įfmpeg -i video.wmv -c:v libx264 -preset ultrafast video.mp4 4. You can use the -vcodec parameter to specify the encoding format to be used for the output video. This command will split the source video into 2 parts - one ending at 50s from the start and the other beginning at 50s and ending at the end of the input video.įfmpeg -i video.mp4 -t 00:00:50 -c copy small-1.mp4 -ss 00:00:50 -codec copy small-2.mp4 3. If you want to split a large video into multiple smaller clips without re-encoding, ffmpeg can help. You can use the time offset parameter (-ss) to specify the start time stamp in HH:MM:SS.ms format while the -t parameter is for specifying the actual duration of the clip in seconds.įfmpeg -i input.mp4 -ss 00:00:50.0 -codec copy -t 20 output.mp4 2. If you are just getting started, here are some commands that will give you a good idea of the capabilities of this tool. ffmpeg -formats to get a list of every format that is supported by your FFmpeg installation.
