Did you read my whole email? You didn't even adapt the filter. Your
filter won't work, as I wrote, you're fading away the combined video!

I literally wrote:

and
> -filter_complex "[1:v]fade=t=in:st=5:d=1,fade=t=out:st=10:d=1[over];[0:v][over]overlay=0:0"

which adds up to:

  -i input.mp4 -loop 1 -i 34232944.png -filter_complex "[1:v]fade=t=in:st=5:d=1,fade=t=out:st=10:d=1[over];[0:v][over]overlay=0:0" -c:v libx264 -crf 23 output.mp4
