FFMPEG Advanced Techniques Pt1 - Advanced Filters

In the past, we've worked with FFMPEG as a conversion tool, but in fact, this little command line utility is so much more! We kick off this two-part series by first delving into some of the more interesting filters provided by the program!

6:03 Just a note, the command “ffmpeg -filters” shows a summary of all available filters, while “ffmpeg -h filter=«filter»” gives information about how to use the filter named “«filter»”. So, for example, “ffmpeg -h filter=eq” gives help on the equalization filter.

*Expand for Notes*

*1. Filters interchangeable between images and video*
In case you're wondering, yes, those filters that I applied to images also apply to video! I used images to simplify the explanation, but you can absolutely use them in the exact same way with video files. Sorry for the confusion!

*2. On Debugging and Help*
Unfortunately due to high IRL workloads, I'm not able to look at your command calls and help diagnose problems. You may contact me at hello(at)nerdfirst(dot)net for paid consultation, if you really see the need.

What a great video! Much higher quality than the average found on youtube.

-filter_complex_script filename

This is much better than trying to inline a complex -filter

This is awesome - I really love the last demo at the end - did you ever publish the FFMPEg command you ran?

Hello bro, can you help me out please. I have a list which contains pairs in the form of (startTime, endTime). I want to lower the volume of all the portions of an audio represented by the elements of the list. I can do it manually by using the volume filter of ffmpeg but i have to write a very long filter demonstration. Can you tell me a method so that i can store the filter description in a text file and then write an ffmpeg command which reads the filter description from the text file

[davidc]

Thank you 0612! Very informative, appreciate the time you took to make this video. :) Do you know if it is possible to specifically change the pitch of a video to the exact pitch you want? For example to the musical note C4? Thanks!

Sir, how to add utf-8 subtitles to video using ffmpeg. we are seeing the letters distorted kindly help

[gyorgykenez]

Although my English is very poor, only the so-called "Continental English" (speak Hungarian and German); nevertheless, this tutorial is useful for me, both for learning the language after voice and for the well-visible command line patterns. Thank You.
I was looking for a solution to image sharpening so I found your tutorial movie. I understood almost everything you said and presented on the subject, but unfortunately this doesn't work for me. Looking further, I discovered that there was a problem with the syntax. Maybe the 3 years difference, but today my FFmpeg doesn't accept >> -filter ”unsharp = lx = 3: ly = 3: la = 1.0” << expression. Fault notice is the follow: Filtergraph ‘unsharp = lx = 3: ly = 3: la = 1.0’ was defined for audio output stream 0:1… could you give some advice, please?
