  • How to convert a Video to a Slideshow with synced audio ? [closed]

    25 mai 2013, par Henry Mazza

    I want a simple way to convert a Ted Talk Presentation to a SlideShow + (synced)Audio format so I can listen to it in my car. I don't want to lose most of the visuals as it does in the audio format and also want to reduce the storage/cell data needs of the video format.

    So far I already extracted the key scenes with timing and the audio, now I must glue this together in a synced fashion.

    Possible ways I found but couldn't make work :

    • MP4Box to make a .m4b (audiobook/enhanced podcast) with mp4chap to set each image as a chapter image (but I could find proper documentation on how to do this)
    • FFMPEG to make a flat movie with the images (but I couldn't make each image stay for a random period of time)

    Ultimately I will automate this process in my VPS and make my private podcast server, so no fancy tools that don't work in Linux, please.

    EDIT : actually the Podcast is a lousy idea, the artwork must be in a square aspect ratio and has great compatibility problems with varius players. Still studing the Book format.

  • ffmpeg concat video and image issue

    11 octobre 2018, par Dion Russell

    I have a video it’s 190 seconds long.
    I want to show a part of the video with audio and a watermark (from 28th second to 154th second)
    and then the video fades out, and then show an image for 5 seconds at the end of the video.

    everything was working fine until i added concat and endpic.jpg

    Here is the script it wrote but it’s not working. It’s really driving me crazy.

    ffmpeg -y -ss 28 -i input.mp4 -loop 1 -i watermark.png -loop 1 -t 5 -i endpic.jpg -f lavfi -t 5 -i anullsrc -filter_complex "[1]fade=in:st=3:d=1:alpha=1,fade=out:st=20:d=1:alpha=1[w]; [0][w]overlay=main_w-overlay_w-10:main_h-overlay_h-10[sonh];[sonh]fade=out:st=154:d=1[sonhh];[sonhh:v][sonhh:a][2:v][3:a]concat=n=2:v=1:a=1[v][a]" -t 155 -map "[v]" -map "[a]" output.mp4
