• Youtube dl for python : set mp3 last modif date date

  24 janvier 2021, par Vladimir Tarasov

  I'm using Youtube-dl (and ffmpeg) in a python project.

  


  The problem I have is that, on download, the downloaded file takes as default the youtube's release date of the video instead of the download date.

  


  My youtube-dl options

  


  ydl_opts = {
    'format': 'bestaudio/best',
    'outtmpl': path + urlToTitleYT(link) + '.mp3',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '320',
    }],
}


  


  Which opt could i use in order to change the file last modification date to the download date ?
(Or do i have to edit it manually ?)

  


• Can I extract an audio clip (a single word) from the video and insert at different points/timeline of same video using FFMPEG/libvlcsharp ?

  16 décembre 2019, par Siddharth

  I want to load a video that has a soundtrack, and I want it to take an audio clip of a single spoken word and I want the clip inserted at different points in the video. The output will be the new video. I also want to insert an image at certain points in the video (watermark).

  Can I do this using FFMPEG or libvlcsharp ?

• In Advanced SubStation Alpha (Ass file) how can I animate each word as it is spoken ?

  29 mai 2024, par Nick Powers

  Hello I am trying to get Ass (Advanced SubStation Alpha) code to animate (highlight in green) each word as it is spoken and then have it revert back to white afterwards. What happens with my code is very odd. At first I cannot even see any text. It then appears with multiple lines overlapped, partially hanging off the screen. From this point it "kind of" works. I can see the desired highlighting happening but because the text is all jumbled and overlapping it can hardly be called a success.

  


  In case it is relevant I am using ffmeg to burn in the subtitles. I am using the following command :

  


  ffmpeg -i FortuneTeller1.mp4 -vf "ass=FortuneTeller1.ass" Subtitled.mp4

  


  The resolution of the source video is 1080x1920 (vertical).

  


  My ultimate goal is to burn Hormozi style text with per word animations. I'm far from that so any input would be appreciated ! If you need any additional info/code to help troubleshoot this please let me know what you need and I will provide it.

  


  I have the following Ass code in the Events section :
