• How do I independently fade in/out multiple (3+) overlay texts over video using FFMPEG ?

  10 janvier 2019, par Balpreet_1988

  When I use this code the 1st text fades out when second text fades in. This should not happen in this code :

  I have tried the provided code in multiple ways but this is not working.

  ffmpeg -y -i title.mp4 -filter_complex "[0:v]drawtext=fontsize=100:fontfile=tst.ttf:fontcolor=0xDEB887:shadowcolor=black:shadowx=5:shadowy=5:text='Top 5 Upcoming Samsung':x=50:y=200,format=yuva444p,fade=t=in:st=0.2:d=1:alpha=1[ovr1];[ovr1:v]drawtext=fontsize=100:fontfile=tst.ttf:fontcolor=0xDEB887:shadowcolor=black:shadowx=5:shadowy=5:text='SmartPhones in 2019':x=50:y=400,format=yuva444p,fade=t=in:st=2.2:d=1:alpha=1[ovr2];[0][ovr2]overlay" test.mp4

  This should fade in 1st text at 0.2 seconds which should stay till the end of the video and 2nd text should fade in at 2.2 seconds and remain till end of video.

• Can't install the modules

  13 janvier 2019, par Megaluk

  I’m trying to install ffmpeg-binaries it works perfectly local but when I go to hiroku it starts to say that he can’t find the modules.

  This is for a Discord bot, running node.js I tried to install with npm other ffmpeg’s but only that works without implementing the ffmpeg itself

  Installing node modules (package.json + package-lock)
