Videos need editing or repair to improve quality and enhance the viewing experience. Sometimes, however good in quality, you may just want to edit, cut, sharpen, rotate, add sound or text over them. To do such tasks, there are a plethora of video editing tools. But unlike paid editing platforms, which may not let you do all the activities, FFmpeg is a complete software project for multimedia files. It has a vast suite of libraries and programs which lets you convert, edit, repair, and improve your video formats.
FFmpeg multimedia framework has its distinct fan following too, owing to its multi-facet utilities.
Recently, NASA used FFmpeg to combine the high-resolution images taken from GOES-R series of Earth observation satellites to create a video. While some miles away, the game developer- Looking Glass Studios included FFmpeg video support in its latest Dark Mod Thief game version 2.06.
Everyone from end users to developers use open source FFmpeg to create, convert, record, cut, stream, encode, transcode, mux, demux, and so much more to their videos.

FFmpeg is a command-line tool that uses commands to convert audio or video formats.
For example: To extract sound from a video and save it as MP3, you can use command line: $ ffmpeg -i video1.avi -vn -ar 44100 -ac 2 -ab 192 -f mp3 audio3.mp3
To increase video play back speed command line is: $ ffmpeg -i video.mpg -vf “setpts=0.5*PTS” highspeed.mpg
It can also capture and encode in real-time from various sources such as a TV capture card. FFmpeg comes with a wide range of audio and video codecs support. You can use to fix your video-related issues of any file format on Linux, Mac OS X, Microsoft Windows, the Unix BSDs, and Solaris systems.
Yes, it can. You can try to repair your video files using various command lines in FFmpeg. But this could be a little tricky for beginners. You should have knowledge of various command lines to perform different tasks in FFmpeg.
Also, the success of repair of corrupt video files depends upon what issue you want to fix and how badly the file is damaged.
To use FFmpeg you need to open a command prompt window and give specific command lines to fix corruption or inaccessible video problems.
Note: Keep your file name exactly the same including the upper and lower case in the command line.
Once the process finishes, you can see the new video file on the Desktop with the file name that you entered (here as Birthday.avi)
Similarly, you can use different command lines for various actions like below:
To check for corruption in the input.ts stream video file and save the errors in log file:
ffmpeg –v error –i corrupted_input.ts -f null – &> corruptions.log
To fix the corrupt video file use:
ffmpeg –i corrupted_input.ts –map –ignore_unknown/-copy_unknown –c copy fixed.ts
If it’s a corrupt MP4 video:
ffmpeg -i input.mp4 -c copy output.mp4
To fix a WMV video not playing and showing message video too long:
In FFmpeg, first convert the video to still images and then still images back to video.
First extract all the frames into JPEG images using command line: .\ffmpeg.exe -i ‘.\Video 36.wmv’ -an -f image2 filename%03d.jpg
Note: Remember the number of images created (say for example 99987 images).
Then, extract the audio using:
.\ffmpeg.exe -i ‘.\Video 36.wmv’ audio.mp3
Find the exact duration of the audio by using command:
.\ffprobe.exe -i .\audio.mp3 -show_entries format=duration -v quiet -print_format json
You would the output something as:
{ “format”: { “duration”: “4325.56210” }}
Now calculate the frame rate of the output video to match the audio and video by diving number of images formed by the audio duration:
Here 99987 by 4325.56210 = 23.1153. This is the frame rate for your output video. It is necessary to use the exact number.
Next use command line and press Enter:
.\ffmpeg.exe -framerate 23.1153-f image2 -i .\filename%3d.jpg -codec copy ouput_noaudio.mkv
Now, use command line to mix the audio and video to get the final perfectly playing video:
.\ffmpeg.exe –i .\output_noaudio.mkv –i .\audio.mp3 –c copy –map 0:v:0 –map 1:a:0 output.mkv
