ffmpeg Fade-in stuck at first frame
14 janvier 2017, par Pradeep VaradharajanI am trying to apply a fade-in effect at the start of a video and a fade-out effect at the end of a video.
The fade-out effect works as I expect. However the fade-in doesn’t. I am noticing that at the starting, when the video is supposed to be black before fading in, the initial frame shows up vaguely and is stuck till the fade duration ends. The Audio fade-in seems to work correctly however.
ffmpeg -i infile.mp4 -strict experimental -y -vf "fade=t=out:st=28:d=2, fade=t=in:st=2:d=2" -af "afade=t=out:st=28:d=2, afade=t=in:st=2:d=2" fade_in.mp4
Can someone please help me understand what I am doing wrong here ?
According to ffmpeg documentation for this filter, the below example is supposed to make the first 5.5 seconds black, then fade in for 0.5 seconds :
fade=t=in:st=5.5:d=0.5

Want to convert my 16:9 size MKV video to 4:3 size AVI video file
19 septembre 2012, par Bimal RekhadiyaI have a video in MKV format and it's size is 720x304 (16:9 ratio) size video.
I want to convert it to AVi format (using xvid video codec). The output file size should be 480x360 (4:3 ratio) and also want to keep the original (16:9) ratio so it should be cinemascope (black areas at top and bottom).
I am on Ubuntu linux OS so I can use mencoder, avconv(ffmpeg) or any tool that work on Linux.
I am trying this command :
avconv -i sample.mkv -vcodec libxvid -r 25 -b 1200 -aspect 4:3 -q 1 t.avi
But the problem is that the video is stretched to 4:3 and I want to keep original video's ratio and want to add black boxes at top and bottom so it will look cinemascope.
Please provide me command to do this.

ffmpeg PNG to mp4 - Black screen
1 answer
I am converting a mp3 to a mp4 and simultaneously adding an image to it using FFMPEG.
Here is the command I am using.
ffmpeg -loop 1 -i ../image.jpg -i "track 1.mp3" -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest -vf scale=800:400 "track 1".mp4
The image appears when the video is played in a web browser. However, it doesn’t appear when the video is played on Windows Media Player or on QuickTime.
Any ideas why ?
