  • Fixing animation strobiness with FFMPEG

    26 juillet 2022, par MarcTheSpark

    I have an animation I'm making with Processing (it's of some numbers moving around on a black background), and I'm trying to avoid the strobe-like effect that happens when the numbers move fast.

    


    I think the way to go is to do some sort of blur of adjacent frames, and I was wondering how to accomplish this in FFMPEG. I could create a high FPS version of the animation (120 FPS or whatever), but how would I reduce this to a 30fps video with some sort of motion blur ?

    


    Sorry if I'm not explaining this well. I feel like the strobiness is a well-known issue with probably a well-known solution, but I'm having trouble finding it by searching online.

    


  • How to mimic Instagram/TikTok HLS streaming capabilities ?

    30 avril 2023, par nickcoding2

    I'm converting a .mp4 file to HLS in Node.js and storing it in S3. What are the important options to pass in here ? I'm currently passing in the below, because that's what was suggested in some online tutorial I followed.

    


    '-profile:v baseline',
'-level 3.0',
'-start_number 0',
'-hls_time 3',
'-hls_list_size 0',
'-f hls'


    


    Should I be lowering the hls_time parameter to say, 1 ? Isn't the smaller that number, the more granular each segment is, and the quicker each segment of the stream will be loaded on the client side ? What are other things to consider here ? I'd like to get as close to TikTok/Instagram media playing capabilities as possible.

    


  • What does 'Past duration X.XXX too large' mean ?

    12 janvier 2017, par Erik

    When encoding H.264 using ffmpeg I get the following type of warnings en masse :

    Past duration 0.603386 too large
    
Past duration 0.614372 too large
    
Past duration 0.606377 too large

    What do they mean ? I have not found anything clear online or in the ffmpeg documentation.
