  • How to compress video applying even blur effect

    17 octobre 2016, par Kukuster

    How to compress video applying well-looking apportioned blur effect, like in JPG image ?

    I tried some ffmpeg postprocesing libraries, they are fspp, spp, uspp (takes really long time to render), etc. I almost reached the goal using fspp with parameters 5:60:15 . But blur was stronger than needed, and it’s leave bad artifacts when i try to use less compression. Also uspp is does beautiful and compresses enough, but it’s leave about 50% of video unblured. I also haven’t much time to try all uspp features. Is there resolution special for this purpose ?

    The point is to implement video compression with the only side effect of compression approaches jpeg-compression-like blur or blur-mask-like. Also it would be very good if there is a simple option to choose between :
    1) more compress, less pretty blur / more strong blur ; and 2) less compress, prettier blur / less strong blur.

    I am used to use ffmpeg and i’m running linux, so it would be so nice if there is a way to solve this with ffmpeg.
    Here is my ffmpeg input data about the video streams :

      Duration : 00:01:03.02, start : 0.000000, bitrate : 4010 kb/s
    Stream #0:0(und) : Video : h264 (High) (avc1 / 0x31637661), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 3870 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 47.95 tbc (default)
    Metadata :
      handler_name : VideoHandler
    Stream #0:1(eng) : Audio : aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 133 kb/s (default)
    Metadata :
      handler_name : SoundHandler

    Edit : attaching jpeg pictured as example of desired output :
    not blured
    blured
