  1. Hi all,

    I am developing a web application using FFmpeg, and I would like to know your recommendations about what filters (to be implemented as presets) my users could use to enhance the video image quality and fix the common video problems.

    I have in mind for example to use the "Automatic Levels" filter (using "pp=al"), "Audio Level Normalization", some "Denoise" filter, and "Deinterlacing" filter.

    But as you can see I only have in mind 4 filters while FFmpeg has a lot of them.

    What filters could I add to a Set of Presets for my users? Something useful. Like a Set of Swiss Army Knife tools.

    I am looking forward to hearing your recommendations.

    Any other tool or fix is good too, even using other software in the shell. No problem.

    Thank you very much in advance!!

  2. you can have a look at what Videofilters are available in VLC video player to determine what you would like to include (+ default parameter values), then look if they are available in ffmpeg -vf.

    adding a small amount of noise can be helpful for compressed video, gaussian blur (spatial smoothing), etc.

    This is what I need, some ideas. Adding noise as a preset might be another one.

    Blurring might be also good if the source is not very detailed.

    On the other hand, I guess you meant to extract the list of filters from VLC in the command line, and then to see if there are something equivalent in FFmpeg

    Basically, I asked because the list of filters is so big in FFmpeg, that I thought that somebody might have a better idea than me about them because of their experience.

    Thank you! Resizing is something I already have covered, but taking a look at some articles to see if I missed something is always very recommendable!!
