FFMPEG Advanced Techniques Pt1 - Advanced Filters

very int video

great video 👍 thanks for sharing

Wow this is help me alot to understand the filter. Thanks for this education.

would you know how to make an audio lowpass filter stronger? i currently have "lowpass=f=400" in my "-filter:a". I want to cut off/dampen the frequences above 400 even more

contrast =-100
Shadoe=+30
White=40
Black=15
Temp=5183k
Tint=30
Saturation=75
Orrange=45
Yellow=35
clarity=-55
Dehaze=-5

Can you convert this preset into code. It is lightroom preset

Can I use bot vf and filter at the same time

Ridiculous ffmpef does not have a decent GUI.

I want an API where I can transfer pixels each frame to something that will store it as a mp4 file ...


Sequencing pictures are really annoying...

'well..' it was a wonder full tutorial :)

Wonderful

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.

Is sharpening filter syntax only for the image or the video file?

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

Nice!

So how would I change the video encoding to SW libebml v1.3.7 +
libmatroska v1.5.0 ?

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

Very well done, thank you

I've known ffmpeg for years but never got to using it until recently, I think i've tried in the past years to no success. This is a great tutorial for filters which is what I need.

Useful video ...
I've converted a file from ts to mp4 using ffmpeg....although it has 1280x720 resolution, the picture quality of the video is blurry....
