  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Creating farms of unique websites

    13 avril 2011, par

  • Freeze frames at a time on videos and slow down videos

    24 avril 2020, par Nguyễn Trọng

    Suppose I have an mp4 video with a duration of 60 seconds.

    



    I want to freeze 1 frame at the 10th second and 40th second and then extend them to about 3 seconds.
At the same time I want to increase the speed of the video to 2 times from the 1 to 20 seconds and 2 times the video slow from 30 to 60 seconds.
The video output I received was 3 + 3 + (20 - 1) * 2 + (30 - 20) + (60-30) * 2 = 108 seconds
Is there a way to do it in one statement ?

    



    Thank in advance and sorry for my bad english.

    ffmpeg -i C:\Temp\test.avi -ss 00:00:30.0 -c copy -t 00:00:10.0 C:\Temp\out.avi

    and this is the output messages :

    The audio was extracted correctly, but I can’t see video (it’s all black). Can someone help me ?

  • Normalizing with ffmpeg-normalize, slight variations in sound

    20 mai 2022, par Antti Rytsölä

    I have some flacs which I am trying to normalize for Spotify and Distrokid.

    


    I got the guide from this post

    


    ffmpeg-normalize inbound/*.flac -t -14 -lrt 11 -tp -1 -ext flac -c:a flac -of normalized/


    


    Now the problem is ( before submitting to Distrokid ) that when listening to normalized versions there seems to be light deviations, like muffling, to the sound at half a second lenghts.

    


    Small sample, towards the end.

    


    Now I'm asking for help because even though I can try different settings I still want to conform to Spotify normalization guide.

    


    The Spotify guide is as follows :

    


    Target the loudness level of your master at -14dB integrated LUFS 
and keep it below -1dB TP (True Peak) max. This is best for lossy 
formats (Ogg/Vorbis and AAC) and makes sure no extra distortion’s 
introduced in the transcoding process.

If your master’s louder than -14dB integrated LUFS, make sure 
it stays below -2dB TP (True Peak) to avoid extra distortion. This 
is because louder tracks are more susceptible to extra distortion 
in the transcoding process.


    


    and

    


     ffmpeg version N-102727-g580e168a94-tessus
 ffmpeg-normalize v1.22.8


    


    Tracks now on Spotify.
