  • ffmpeg showing really bad results when converting to JPG [duplicate]

    8 avril 2014, par Shazam

    This question already has an answer here :

    I have this simple command :

    ffmpeg -i  movie_file -f image2 ./%d.jpg

    The result with JPG is really really bad, and in PNG is much better.
    The problem us that the png is 197KB and JPG is 7.1KB.

    Is there anyway to compress the PNG more ?
    what can be done about this ?

    see bellow, png on the right, jpg on the left.
    what can be done about this ?
    Thanks

  • Ffmpeg : Improve results with h264_nvenc video codec

    7 avril 2024, par Sulli

    I was very happy to discover ffmpeg is compatible with Cuda as using a GPU speeds up my processing time by 10 at least. But I was very sad to discover codec libx264 can’t be used and h264_nvenc is of much poorer quality (my videos are visibly pixelated, to the point I actually don’t see why ffmpeg was made compatible with Cuda in the first place :) ).

    


    I did not tweak my ffmpeg commands at all when I switched from libx264 to h264_nvenc, but maybe there are some parameters I could add to get a better quality ? Even if it leads to longer processing time, I don’t mind trading a bit of that for a better quality. Or maybe another video codec I wouldn’t know about ?

    


    I usually run my scripts on Google Colab if that matters (tesla T4 graphics card, Driver Version : 535.104.05, CUDA Version : 12.2)
