i want to add two PNGs and two text on top of an input.webm
.
each overlay is shown for one second.
i have already converted the png to webm and they are called text1.webm
and text2.webm
the output goes to output.webm
(the ffmpeg is split in lines for readability)
ffmpeg
-i input.webm
-i text1.webm
-i text2.webm
-filter-complex
[1:0]overlay=0:0:enable='between(t,0, 1)';
[2:0]overlay=0:0:enable='between(t,1,2)';
[0:0]drawtext=enable=between(t,2,3):fontfile=arimo.ttf:text='text3':x=100:y=200,
drawtext=enable=between(t,3,4):fontfile=arimo.ttf:text='text4':x=100:y=200
output.webm
